 about here live from New York it's ask a couple engineers everybody but two engineers one of them is very trustworthy oh thank you trust for the engineer you trust this man yeah we've been exciting show tonight with billions of new products all sorts of news and of course a special guest we will be talking about that shortly that's right let's start the show off okay on tonight's show the code is trinket 10% off everything in the Adafruit store the code is trinket expires 1159 p.m. tonight we're going to talk about the show and tell we got our friends from Adafruit East Adafruit West Adafruit South all corners of the Adafruit globe oh yes we have infested your country sorry Adafruit's we'll talk about an exciting new book that everyone to get it's getting started with Adafruit trinket the author is here Mike Barela we're gonna talk about some of his projects we're gonna talk about trinket and more Adafruit learning system we're gonna have a couple tutorials we're gonna talk about and then guess what Lady Adafruit we're gonna go straight to new products because we have two weeks of products I know yeah so we're gonna we're gonna do that yeah all that and more you guessed it I'm asking engineer okay I can deal yeah we're gonna do this okay so first up pay some bills coast trinket celebration of Mike probably sending his book to the publisher it's very close don't ask now the maybe the last revision before going to the printer I think they want to get it to the printer in several days and then the ramps up and everything so all right it will anybody doing pre-orders with booksellers are looking forward on in your store very soon all right you heard it here speaking of discounts and buying things and more we still take bitcoins Mike have you ever used Bitcoin for anything I have not yeah I was very tempted to build a miner from you guys's tutorial but you know I I just get very busy between way it's another job I mean we have we have the miner project we've done a bunch of stuff with Bitcoin but I couldn't keep up with it when things were changing so fast and all the different wallets and all the different things I can accept Bitcoin as payment like I know how to do that I could do you know like website and business stuff for Adafruit but I've personally not used Bitcoin to buy something that I wanted to buy online yet feel like I'm missing all of it you might be I bought I used bitcoins to buy those Bitcoin miner chips which then like totally didn't work out and I got a refund and then we ended up making money on the failed order because the Bitcoin price yeah so we did buy something with Bitcoin okay so technically we did we bought chips to mine bitcoins yeah yeah I think a lot of people might do that I think a lot of bitcoins are used to buy things for Bitcoin it's like it's a self-fulfilling hobby okay we still have our free deal going on right now $200 gets you free UPS ground the continental US $50 more gets you a free oh sorry $99 more gets you free Adafruit half size permapretta all right lady we had the show until we are shown tell is super quick we don't know if there is a Google plus issue because we're trying to be sneaky what we wanted to do was have the show until be a staff meeting right before the show until and so we invited our team member circle and then we invited the show and tell circle so we don't know if that's possible because we have a huge number it's a Google plus like who knows like it maybe you can't and make her fair too so we don't know so we're gonna try something different but we had some cool stuff from our staff members yeah we had none Pedro show up and they have 3d Halloween projects also don't forget tomorrow is 3d Thursday with Matt no and Pedro everything that's fit to print be tomorrow so check it out they also showed off this really cool Cortana costume apparently that's their neighbor that's so cool they have a neighbor that they made a Cortana costume on it's halo with them that's awesome and then Phil B actually wanted to try out a project where you had multiple raspberry pies on Wi-Fi with fake candies all synchronizing to one host computer and he says it works quite well so people want to synchronize moving LED projects like if you want to dance costumes or like you know to look computing moving blocks or robotics you can have it all use Wi-Fi as your wireless protocol instead of like doing XBs or something and then Tony showed off the beagle bone black and pie temperature sensor stuff he's working on he took our most popular raspberry pie temperature sensors TMP 0 0 6 MCP 9808 hybrid season thermal couple amplifier max 31855 and ported all those Arduino libraries to Python so they work great with the beagle bone or a raspberry pie either or or any other operating system that has I squared C support or bitbang support and can use Python so it'll be really handy for people who are not using Arduino and want to use our code that's it it was fast yeah all participants on the show and tell who aren't staff members again as you know the show sticker that's right they also get all the free Adafruit gear one of the most I guess best perks at Adafruit is if you work at Adafruit you get all the electronics you want there's not even like a discount you basically just get whatever you want for free yes you have to build something with it yeah that's what we decided on eBay it'll be weird yeah it might be better for some of our customers who really buy everything just to come work for us so how do they join the show until if you would like to show up next week for the show and tell super fun party with me fruit fruit faction Phil and other special guests go to the Google plus page at plus little dot com slash plus symbol Adafruit and find the thread where we say common here to get added to the show and tell circle once you're added we will invite you next week and every week following on Wednesdays 7 30 p.m. Eastern time you can join and show your project can be the tries can we crash can be your Halloween project anything like it's cool like some people show up and they're like I made a basket I'm like that's cool it doesn't have to have the LEDs in it I mean like LEDs will make it a little better but okay with just baskets and join the party get free stickers I electron-sized my daughter's dog last Halloween and I showed it on show that's right you had the TARDIS that's right that's how I think we we met you right Mike over yeah show and tell that's right I think a show until or I think you had done a project and posted up and like the Google plus comments or something like that was one of the or both yeah I think maybe you'd notice I'd done some work with the splora I made sure everybody knew what the connector wasn't then figured out that you're me and another person on Google Plus figured out the pinout for your display was the exact same pinout these are displayed totally terrified he well he that's just as personnel yeah that project inspired the soundboard that I'm working on now okay so so speaking of origin secret hero origin stories yes Mike is here so Mike so Mike is a senior foreign intelligence service officer with the US Department of State he's a graduate of Whitman College in California Institute of Technology and Electrical Engineering you've worked at HP NASA Boeing you've traveled the world lived a number of countries including providing security to the American embassies and avid electronic enthusiasts you've worked on computers since the introduction of the PC you rekindled your level electronics and microcontroller interests by authoring a number of popular articles using a different compatible I'm sorry the Arduino compatible systems this includes collaboration with a different industries on their popular trinket microcontroller Mike bro welcome welcome to ask an engineer thank you you can read from the book thank you for having me it's wonderful actually seeing all the behind the scenes and it's just such a great company to be involved with well first thank you for making so many cool tutorials so we knew the trinket was gonna be popular we just needed to make sure that people got an idea of what they could do with it and so we sold how many trinkets so far I believe it's like 25,000 25,000 out the wild don't know I didn't count the the packs but yeah yeah so it's a very popular platform and thank you for sharing all these wonderful projects with people it's so essential they're fun and and oftentimes I just get an email from Phil saying hey what about this great idea and it's like yeah sure together and or if I had an idea I could pitch it to you and it's just a such a great collaboration so after you wrote all of these tutorials how many I'll tell you well yeah well there's there's so many it scrolls off the page but um well some are by other people no I don't think I wrote 20 some are by other great you're a 14 diners okay yeah 69 pages and there's there's my my daughter's afraid dog and the King Charles Cavaliere spaniel was bred to be completely terrified of everything except for sitting on someone's lap well that's that's they love yes but they passed a law in England that they could go anywhere and they couldn't be disturbed because they were the other kings don't roll dog yeah but wait it's like a holy cow yeah I know it's kind of falling out of favor you know all right so so I have a question so you have a very impressive background so you're a senior foreign service officer with the US Department of State so you're an engineer for the US government exactly so what is that like it's great I mean yeah I had some background before with other places but it was kind of recessiony and not a lot of jobs and you work for a big corporation that makes airplanes and you kind of lost in the crowd but then you see that'll add in the newspaper says see the world interesting people and do engineering and it's like whoa I never knew that existed most people don't so we actually we go to career fairs we go to engineering fairs we we try to let people know that you can love engineering and also work for the government and see the world and you know help our country so how long have you been doing this 26 year okay so obviously you like it I do yeah it's a it's a great job it's a because we're in the State Department you know you're not it's not like you come and go with whatever whoever's president or in Congress you're this is a job job it's not like that's it's a job job you're you're you're foreign service which is kind of like civil service except backwards and and and you're yeah you're just doing it you don't flow in and out and since the engineering that we do is related to security security has just grown over the years and it's a an issue that the government still has a lot of need for and so there's no kind of let up in the hiring of the people that so anybody watching who is a US citizen can apply to one of the many positions right all I have to do is go to careers dot state dot gov and look for security engineer and they open it up to applications every now and then and you have to do a little little testing to see if you know your stuff you have to have a bit certified degree in engineering or physics I believe yeah we have physicists we have chemical engineers you know it it helps a little bit to have electrical engineering because there's a certain job I mean yeah there's there's positions for all types right but they train you and in all the systems the government does and they teach you about overseas life and then you go out and have a lot of fun okay so how many countries have you visited I knew you're gonna ask I've only visited probably about 25 countries well my colleagues some of my colleagues have visited well over a hundred I'm just not as well traveled I guess okay so you do engineering on a regular basis as part of your day job or you managing people or what now now being in so long I'm relegated to managing engineers and projects and stuff but yeah we if you're joined up you're doing engineering basically on a daily basis overseeing lots of projects within Washington or overseas there's a build stuff and you get to take apart stuff yes and and it there's a wide variety of all kinds of equipment and designing systems and it phases over from security and to cybersecurity and it's a lot of fun so and I was gonna say so you're managing people so you must be like boy if there was some engineering I could do at home because I'm you know all engineers they seem to do engineering at night and they also do engineering day so the trinket came along and I guess this in Arduino and this stuff probably you know started making you think hey like this is it looks like it's a good time to start soldering and building stuff is that how it well I'd really wanted to kind of transition from my hobby was computers and and doing a lot with PCs and then I just really had that itch from using microprocessors from the college here and I wanted to get back in it so I started just like most of your customers with Arduino and starting the basic projects and then Explorer came out and I thought oh that's cool it's kind of like a game and actually I found a couple games and talked to the authors and poured them over to that and then you guys introduced trinket and it was like cool you can have well you have a 8-pin microcontroller and it's again inexpensive enough but you can just throw a bunch of neopixels on and just like wow people so that that got me going they're not a lot of neopixels at the State Department yet no there's not I want to use some throwies to kind of like get them involved with it but one of the things I like about your approach with all the trinket stuff is so you know the trinket isn't a FPGA or that can like do everything an emulator so it can't it can't do all the stuff there's constraints and with this constraints you can be very creative and I and I like how you've taken some of these projects and you know you only have so many pins and so much memory but you've managed you very complex projects that turned into a book yeah and well not just my project there's a couple projects again from the age of fruit team but it is a challenge I mean like the occupancy sensor that's one that you sent me a university wanted something for their their rooms and I had to really kind of engineer that one because we were within like 10 bytes of maxing out the flash so yeah exactly and just just little tiny changes you had one little line of code and boom so it's a challenge what I thought I would do is I'd give lady a chance to talk about where this trinket came from so there's some photos and we've had we've had to trinket for a while it's one of the fastest-selling products that we have it's one of the things I like to tell people it's it's not disposable and in terms of you're gonna you're gonna throw it away and there's a trinket dispenser although maybe we can do that one day but it's one of those things where you're not scared to put it in a project and it could get damaged or wet or you can experiment and it blows up it's not a big deal like in in the arena world around $30 still a lot of money it is if it doesn't work out so what was the origin of the trinket what what made you decide to make this little so I step platform actually got the exact she been using the 80 tiny 85 I used it for that TV gone so I actually use the chip before and actually really liked it because it's got 8k a flash only eight pins but it's internal crystal and like it's kind of like fun to use because it's like it's just a it's just like a really low profit dollar less and then I saw that de melas who's on the Arduino team added a little had a little add-on that added 80 tiny 85 support and I was like okay that's kind of interesting and I started to see more and more people do projects with 80 tiny 85 and I thought like well the nice thing about this is you know it can do USB bootloading is it like kind of sort of by like sinking with like the J pulses on the on USB and you know you can make a really small 2k bootloader you still have enough to do a little you know have like 6k a flash for doing a project so you know I worked on it for a while and like Frank Xiao who did the bootloader imported the USB TV bootloader onto it but basically it was like what what is the minimum amount of stuff to add on to make it basically a lot like an Arduino to power LED a reset button a red LED so you can you know get blinking immediately also tells you the bootloader is going and it has a little USB plug and you can use it on a breadboard just like what's the minimum and how inexpensive can you make it so that you can because a lot of people like a fixie bike Arduino yeah no brakes like you just have to like stop pedaling I like the teensy which was a Paul Stofferton's USB VR board and what I liked about it it was it was really low cost and very easy to use and have USB built in and it was just like okay you're just it's small and you can easily embed into things and there are a lot of projects we want to do that was like well nothing will fit you know like you wanted to get into it a costume or a prop or a wearable you can't fit a full Arduino and even like a micro can be a little bit too big and also it's a little expensive so having something under 10 bucks was kind of like the goal and so like all these little things kind of came together and we had the pick-and-place capability to pick-and-place the small parts we got the new pick-and-place and that was like a really good part to we couldn't do with the old pick-and-place we have to have this one yeah because there's all these 603s and you want to have everything lined up and you want to be able to make them very fast yeah and so Mike what other dev boards besides of course trinket and our in Arduino stuff but what other dev boards have been playing around with as you've kind of returned to your electronics hobby well I must say that writing the book I've I haven't had a lot of chance in the last six months didn't use any dev board like in six months like everyone releases a new dev board so fast exactly and then you have a lot of parts coming out that you know everybody's salivating over and I just saw that Edison just came out and there's all kinds of things coming out but but it's not just that when I'm interested in is I really like the fact that especially a different you're lowering the barrier of entry again you said in that like the intro to the book and in the old days just to program a controller you had to have all this equipment and and and it would be nearly impossible for anybody with modest means to to get into being able to do that but you're taking open source and creative design and making it so not just a person with an engineering degree can do this a person with a design background or a hobbyist just get or a seven-year-old who'd like this is one of our biggest growing customer basis is really really young kids and they know what they want to do and so this is the these microcontrollers are just one of the ways to get there they have projects in mind they don't really care it's just a tool for them right so I'm you've provided the means the book is providing some steps how to get there one way to get there or to be a reference also so if you're playing with this and you say oh I I really don't know how to do a certain thing you can go look it up real quick and and you have it and then you can go on you're not stuck with your project you're saying I just really can't get over this problem hopefully this will lower some barriers along with again with with the hardware you've built so people can actually achieve what they want to build yeah it used to be like man I mean well nothing I like about the 89 85 so it reminds me of the first processor users that pick the 12 f 808 ooh I don't remember 16 I don't know I'm not 16 if it was the it was the 508 the pick 12 C 508 which are in 509 which were like two one one or two K and and these were like really cute there were eight pin microcontrollers and yeah you had power ground reset and then you had three IO pins and you can do actually quite a couple projects of them but you need an e-prom burner right because it were a racer are you be a racer because they you could only get them in either one time or you know the five dollar like with the golds and the crystal window and everything and it would take like ten minutes to program it's the fact that you could just plug something into USB and just program you don't even need like a like a pick programmer with the flippy switch man it's so easy nowadays yes so for the book there is eight chapters introducing trinket software installation connection and programming libraries optimization optimization intermediate projects advanced projects going further with trinket troubleshooting making electronic sounds part sourcing and publication so eight chapters all together it's a little bigger than they had wanted originally and it was going to be black and white and then I think they really liked it and they're just like we think yeah they didn't they didn't seem to want to cut it down which they could have they liked the number of projects but also I think they did you wowed them with pictures of the neopixels and and the other yeah content that we put in so they just said okay we'll we'll spend the extra to run it in color so the images are in color yes wow yeah they switched up so the getting started books are black and white black and white and they don't really how they don't they're not meant to have a series of projects where you show this it's more about like how to get it started installing an IDE and just like okay this is how a computer program works on this microcontroller and Adafrit style is we trick you into learning all that because you want because you want to have that neopixel product you want to have that thing that that lights up so I used to write books and I have you know memories of kind of the challenges of writing book what was the best part about putting together a book and what was one of the more challenging things for you about doing a book about a lot of rocks well I'll start the the challenging I mean to try to get from writing tutorials to get to the book they're they're a little bit different medium so you want to I realized actually it might actually make me a better tutorial writer having written the book and the thoroughness that you want to do in a book because you don't want to skip something that might be like an engineer would think is just something you just don't think about doing yet somebody again the seven-year-old with their mom or dad doing the project and it's like how did the person get from a to b and engineering school they call that and the look and the rest is left to the student you know from a to b homework exercise yeah no this is the hardest part exactly you have to be through it because you can't just say Google it you can't just say go to the tutorial has to be all the book correct and so that was I was a little challenging but it was also I think it was fun in trying to take myself as the person who would read the book and say okay what material would I need to understand this better and so the the learning system and the material was there helped but I spent a lot of time in the Adafruit forums and there was I was looking at questions people were asking and if I knew the answer I'd answer it but a lot of questions I didn't even know about and then one of your forum members would would present an answer and it's like oh wow great and then I would incorporate that answer and then again no one needs to do a forum search or revise a tutorial that that this information is all together and in the book yeah we have we have like four or five paid engineers in the forums that they work like you know 20 to 40 hours a week because everybody has their own little experience like oh yeah like really tough ones like okay so I'm stringing the sensor and the cable is 20 feet long and then I get spurious something and I'm like okay so you have to like actually get to like serious engineering especially since you're not there in a deep bucket and the oftentimes you're like do you have a multi-meter like I do not have a multi-meter I'm like okay let's try like eight things and maybe one of them will fix it so that's that's another thing that's tough about writing books electronics to beginners is they don't even have a multi-meter sometimes much less an oscilloscope to prove right I I recommend they get a multi-meter and you can get some great ones for exactly I say that you can a oscilloscope might help in some things but that's maybe something that somebody might want to go to a makerspace or a school or something and look at using because that's a that's an investment so if folks want to right now they can get the early release through the e-book system that a Riley has right and you could just search for trinket on shop.aureli.com correct and then you're going to be releasing the book probably when when people are well again in the publishing world is about a slippery as the ate a fruit release schedule so definitely next month okay that's great and I'm told I this is not the most solid information but if anybody is attending World Maker Faire I believe they might have some hard copies of the early release okay all right they go and listen to me talk about it at 11 o'clock on Saturday I might even sign it if that was even it doesn't increase the value of the book but I would be glad to to talk to people about it I mean I'll be hanging out around the the author tent is this your first maker fair that you've been to no yes there was the northern Virginia Maker Faire that was the first one I attended took my bride out there and we had a good time and then Brian Jepsen was working on the DC Maker Faire which was right after the White House Maker Faire and and we were editing the book and after we had talked about the book I said can I help out and so I helped them set it up so I've been on the outside and inside okay so with all that being said we are going to dive directly into new products so Mike I want you to participate in China chime in ask questions as we're doing this you can be the audience advocate just like you are the book we are before the show got going I gave Mike a tour and he said boy you guys are releasing a lot of stuff and we are we got all these new machines lady it has been on a terror and so the only downside is we really have to tell everybody about these products so do you want to switch places more do you want to go that way and Mike and center yeah why don't you go this way and put my concern okay so right before we show the banner drink it drink yeah pretty much everything you see if it's in stock is 10% off so lady Ada okay ready for this grab the bucket okay it's new product time thank you okay over there so okay you ready for this yeah okay first up we got a new power supply okay so we have these new power supplies and we actually start ordering these before the Raspberry Pi model B plus came in they are two amp five volt power supplies in the USB port these are really great if you want a power like a Linux machine like a big global black or other package I can fly 10 sorry five volts two amps and we have two versions one can go back to has a USB port and you can plug in like you actually has iPhone resistors quote-unquote iOS resistors you can plug in a tablet it'll charge it two amps or an iPhone it'll charge it like an amp or whatever so that's you can do that you can use any USB cable you want the thing is if you're drawing two amps though a lot of USB cables are kind of cheap and they have really thin wires in them cuz like I got this dollar USB cable yet cuz the wires are like 30 gauge it's fine if you're just like plugging in something for data but it's not good enough if you're drawing two amps no and all engineers they got to watch the gauge wires I tell people in the trinket book fifty percent of the issues are off pretty much their USB cable you believe like I've seen the power only USB cables and I'm daylight I say it's gonna give you people but we also have a version of this power supply that has a USB cable built in and it's an extra thick wires 20 gauge which is like really thick for a stranded wire so it's a nice hefty cable and it will only drop like point two volts even if you're drawing a full two amps so like it's totally great for use with your anything that has a micro USB connector especially Raspberry Pi model B plus because you have the four USB ports but of course you can use anything else needs to be powered I'm also gonna mention this so we go above and beyond so this is a UL UL SCC CE yeah high quality power supply and so super clean power doesn't droop or flicker yeah this is actually a high quality one and so we're at the point where big institutional buyers when they contacted us they actually require this now they're like hey is it you is your stuff UL and all that yeah so we're not the cheapest there are definitely super sketchy cheap ones that you can get out there but we really spent a lot of time on this if you're gonna plug this into your $65 Linux board you know power and they have a little bit of headroom if you look at this one I think it's 5.1 volts and the other one is like 5.2 there's a little bit of extra voltage headroom so with the voltage drop across the cable it'll still it will never get below like 4.8 volts even at like full current draws this is a really good choice if you want to run a big monitor off you know if you have like a screen and a Raspberry Pi and Wi-Fi and like you know in sdr radio all that good stuff this is a good pack yeah to get all right next up so we got some battery we got this battery this is actually a battery that I got for a special purpose this is a 2 amp hour lipoly battery standard rechargeable lipoly battery 3.7 volt nominal 4.2 volt max works with every one of our lipoly chargers I specifically got it because it fits perfectly into the battery pack one to the other end let's do the overhead so I can just show it this is like the exactly the perfect whoa so for the battery shield that we actually just put back in stock this battery fits in exactly I had it like custom fitted and it's 2 amp hour so this will run your parts for a long time and it doesn't it's not too tall so you can stack a shield on top and yeah it's a good battery that's what I got it for but it's also handy in case you ever need you know 2 amp hour battery at a good price okay use it with any of our chargers batteries very long so little display little display is a big display this is the teeny one it's a 1.44 inch diagonal tft display it's a tft so that's just pretty good color 120 by 120 pixels it's a little cost it works with Arduino you know we have like projects it actually uses the same chipset as the 1.8 inch tft it's just cuts off the bottom 32 pixels whatever it's good for little projects it actually looks really good there's a micro USB so you can display images we have code tutorial I don't have a demo for it but you know it's a display you can see the images and imagine how big it is okay we're like long next up this one is a bigger display this is our capacitive 2.8 inch tft breakout so if you want to add a capacitive 2.8 inch tft with touch single touch display it's beautiful it's colorful it's got capacitive touch a lot of people have been asking for capacitive touch not just resistive capacitive touch has a much nicer feel also display looks much better because there's no you know rough overlay the overlays like pure glass and it's patterned and I even have a demo for it over here I just have to hear it wired up sorry I had to be with me yeah ask for engineers so this is the display you can tell it's got a nice black background and then instead of using your fingernail you actually use your fingertip just like you know most smartphones these days and most devices these days so yeah okay so is the buffering on the display or is it in the processor so would you say is the buffering in the processor or the display the display it actually has internal video I'm this is one of the many of the displays we have like the one we bought before they're not raw displays actually have VRAM inside display so you write to it with SPI or 8-bit so this can be used by like like this is why Arduino which has like no memory at all can drive it but you can also connect it for example to a Raspberry Pi or Beaglebone if there's we have the example code for Raspberry Pi and I think also Beaglebone for this display so you can use Python PIL the Python imaging library or Pygame or whatever to just display directly on today here's a question for the engineers if you want to take it what's the difference between capacitive screens and resistive screens with resistive screens have two thin layer Jeopardy buzzer it's too little layers that they have resistive fill of coatings and when you press the button or you press it the screen with your fingertip you're actually shorting the two layers together and actually potentially on but are you're shorting these two conductive layers and then the resistance resistivity of the layers is what gets measured with capacitive it actually your body acts as a fluid thing yeah yeah so you have to touch it with your finger you can't use your nail you actually be conductive to your hand has to be skin yeah banana use fruit yeah fruit is good yeah if you're holding free that's that's where the name of the company came from if it's things that you can make work with a touchscreen well people that what people like about capacitive is that it's this you don't have to push on it you just you can just lie your finger over so it's a much nicer feel also you never have to calibrate it because the calibration is fixed so you it never goes out of calibration like resistive does and also looks better looks much clearer because it's just this glass covering instead of the resistive covering so but it's more expensive so there's all right we're on our journey with new products here next up this we just put it in the store yeah and this is a big deal this is we had this for signups and now we have it in it is the pie tft 3.5 inch I wanted to tweak the kernel a little bit and update the Debian package and I learned how to do that today this so we have it now in the store and live and you can buy it it is 480 by 320 pixels it plugs right onto your pie with the pie model a model b model b plus all the pies we have a install script that installs our kernel onto it and then it actually just like boots right into the console and you can run x so you can run pie game or you can run whatever that normally you do to the display and you can also have hdmi on the side the hdmi is a different output so you can have both if you want it's a lot for the pie to do but if you want you can have likes you know something running on the hdmi monitor and then little display for something else our 2.5 inch pie tft is really really popular and so we wanted to upgrade to a bigger screen so it's twice the resolution but it's not twice as big it's only a little bit bigger so the density is much nicer the pixel density and this one has a resistive screen we'll eventually have a capacitive screen to you but you know there's definitely no UTA on that I haven't started but resistive works quite well a lot of the pie stuff has been going on probably why you've been knee-deep in book writing are you gonna play around with pie stuff I have played around with pie stuff I made one of those little pie laptop tablets with the atrix the laptop dock right exactly and I go way back with unix and all that stuff so I'm gonna ask you like if you have a Unix background or if you I do have some and and I did that at Boeing and I did some things that might actually be called hacking right now as far as capturing co-workers passwords and stuff but no so so this I really find the Raspberry Pi a great product because it actually allows you to use a larger operating system but not something either obscure is like risk OS or something unless you really want to and then the ecosphere that that is creating both the hardware Adafruit and other companies and the software I mean people are writing libraries and again you don't have to if you don't want to try to figure out all the the nitty-gritty you can just say there's open source material out there and and I can take that yeah there's like again like Python libraries like there's tons of Python so yeah I'm showing the here's a display live it's got four little mounting holes that you can they're perforated so you can break them off with pliers if you don't want little mounting tabs it's exactly the same size as a pie so if you have like a case that just fits the pie that way it'll it'll snap right on and I just have a keyboard connected to the pie so I'm gonna log in so yeah just you can use it as a console and then I will start X little not crash why would live demo there you go and yeah you have a you know a fairly large display here that you could run stuff in so like for example if I want to run idle or you can run a web browser if you want you can you know use the touchscreen you can use a mouse and keyboard all's good and yeah it's big enough that you can actually use it for a lot of stuff and I think it'll be popular uses SPI and for the resistive touchscreen and the display you can get like 20 frames a second depends what you're doing if you're trying to play video just one of the you know the pie itself is not great at playing video but I you know it can it can display stuff at about 20 frames a second or faster if you overclock it alright lady we're gonna kick it up a notch we guys we got like eight rows of products do you think okay here's cables extension cable yeah this is actually used for a future project but it's basically if you have something that uses a 40 pin flex connector like our TFT displays and you want to extend it like see here you've extended it this little extender you can plug the FPC into one end and then you know whatever 20 centimeters later you've got the other than the cable it's just extender but handy if you're like I want this display to be farther away from the driver board even though like sometimes not supposed to like extend like high-speed lines you know you can try it often it works just fine okay next step extended right we got a book this one by request designing circuit boards with Eagle once we started selling the Lady Aida selected versions of Eagle a lot of people said well I'd really like to to learn Eagle so do you use any cat tools at all um yes I took a great course on kikad with the YLM guys oh yeah yeah we have a kikad badge and a Gita badge that workshop to use to ward when people learn it and then today Altium has a like a free version that's a lot of people been asking for free Altium for like yours because it's like it's a super expensive tool I don't do anything that needs it we don't do like I think that like requires Altium I like the stuff we do even you know Eagle now has matched trace length so like the only thing that was really like I wish you could do serpentines like Eagle does it now you know is Eagle the best no it's also not the worst it's very ubiquitous very ubiquitous and all cat software is difficult so given that next up this is kind of a big deal we worked on this for a while with the folks from Leap Motion we are one of the few companies that have the Leap Motion sensor so it's it's a USB device yeah I guess you should describe it it's because it's weird yeah it uses it's basically it without infringing on anybody's patents I believe it uses the same technologies connect similar where we didn't actually people have experimented with this before it uses an IR camera and IR grid or mesh and it projects that mesh and then it can detect the mesh I mean the demo shows it being able to detect each finger I'm not everybody loves spinning globes with their hands for demos that's a lot of fun I think you can do basic motion detection there's an API I think detecting each individual finger you know depends a little bit on the light and usage and people's hands and stuff but you can I think do like the demos at this one where you can sort of do hand motions I think does work and there is a community of developers a couple thousand developers who are doing stuff with the Leap Motion so I thought it would be an interesting thing to add since it is a sensor like many others that we carry in the store and they seem to be really interested in getting a developer community and you know there's not like a made for Leap Motion like thing you have to pay into it so anyone can give out for it they encourage it and I my wife really one-one we bought one and they must have thought I was a developer because they keep asking me to to try to join the developer group and it's like well I'm I'm just trying to get the wife acceptance and coming soon next year getting started with Leap Motion SDK by Mike Borrell oh wow that's a lot of writing awesome all right moving right along lady at it this is actually a sub part of the next part is a little adapter board that we made for the click touch screen add-on HDMI monitor so we now have a five inch 800 by 480 monitor we have one with a little HDMI only driver we also have one with a bigger driver that can do BJ in compositing okay basically what we do is that these screens have a resistive layer over them and we split out those resistive lines and connected have a USB connector so you can use this with actually any computer that has HDMI and USB it shows up like a mouse and you have a research screen so I can show it on the overhead okay I should plug into a pie but you don't have to use a little pie you can use it with anything you want to use it with a yeah I used it with a beagle bone black and a Windows computer oh can you actually hide my face you face I'm gonna hide you yeah yeah I just turned down the light because it's it's so bright from here but yeah you have a you have it connected to USB through this little adapter and we'll eventually have like some sort of enclosure or something and then you know this just looks like a mouse you can see it every time it detects a press it actually blinks a little bit and these are you know we calibrate these in the factory so when you get it it's just ready to go and yeah you can do whatever you want with the with a monitor and use it as a as a generic touchscreen what I like about this is it's not too big a five inch display it's like it's kind of like tablet sized but you know it basically because it can run HDMI it's HDMI it can work with any computer so if people want to do single board computer interfaces that had touch screens but they wanted more resolution than the pie TFT so this is 800 by 480 so that's almost three times as much resolution as the pie TFT 3.5 inch so yeah it's basically we have multiple touchscreen solutions like pie TFT sits on top this is HDMI so it can it's you know higher resolution and you know it's much faster and much bigger but it's more expensive so there's just trade-offs okay and then I guess this is another yeah then we have the version this is I think the version that has the it's just a bigger driver okay so the HDMI driver in this one also can do VGA input or composite input if you have something that has composite output for some reason you want a mouse I don't I don't know what that would be but let's say you do or has VGA which is pretty common if you have a computer that has VGA output and doesn't have HDMI you can use this monitor just fine with that as well so we have it's a little bit more expensive though because that's all the extra ports so again trade-off do you want HDMI only less expensive or VGA or composite or HDMI input and it's you know the figure okay we're still need even new products here so we've got these knobs you know these are the best knobs these knobs are the best and like people like we've got three colors red white and blue which is yay American or French and these are soft touch knobs now I can't we don't have some sort of simulator that you go put your hand through the display and feel how nice and sticky these knobs are yeah but they have a nice soft rubbery silicone feel that is really grippy because I really hate like the hard plastic knobs these are nice and soft they fit they have such an opinion about until until you have really crappy knobs and then you're like I wish I had those soft just now and I have to agree I've used a lot of knobs and projects over the years and a lot of them came from Radio Shack and they were hard and slippery and these are extremely nice no if you want to dial in exact excuse me values these are the knobs okay you know I have opinions but you know why everyone who like is building synthesizers and these are um this is a T18 so this is the 18th spline very standard the other standard is D-chef well I'm working on getting D-chef ones too but for now I have T18s these are well known and yeah they're skirted and they're lovely and I don't know I love these knobs okay they fit great on the potential we have in the the panel mount and breadboard friendly ones in the in the shop so yeah okay so tweak all you like well we have plenty of knobs next up we have an updated version of our ruler yes our PCB we demand we now have the ruler with one-tenth inch markings not one eighth inch all the electrical engineers we're like everything is on a point one inch grid and so we want to have the grid on the ruler too and I'm like yeah but no ruler has one-tenth and unless you're an architect and they have the scale rulers but anyways it's now one-tenth okay I hope you're all happy okay the one-eighth people are gonna be very sad they're gonna be so bad but yeah well I understand most stuff is point one inch boundaries okay next up JTAG adapter this is a thing that you only need if you know you need it you're probably like what the heck is this if you have something like a sticker JTAG programmer which like I have holding up here like we saw in the store we have the edu version I can get other JTAG adapters they often have this ginormous chunky 20 pin connector which is great if you have like a motherboard but not great if you're making like a little Cortex M3 or M4 or even M0 eval board or break up board oftentimes you'll use it will SWD connector which is a little guy I'll show it on the overhead how teeny it is it is half an inch pitch so this little cable it basically adapts from this chunky cable a little chunky cable to this little one we will be releasing boards that uses connector so we have to have an adapter because well like you can tell it's like you can't bring boards this little cable and yeah it's just adapter if you know you need it you're like oh I need that we have it it's great doesn't big to small and then we have these cables sold separately they're the little SWD cables if you don't have one you get a cable oftentimes you have the cable you just need the adapter so there you go SWD okay JTAG next up I can do this one so we got this in we are continuing to put in more types of filament so this is the ninja flex and this is a new color this silver metallic so if you want to thank you engineer all right it's not shiny metallic but it is a is a silvery metallic yeah it's like a silver yeah so this is a flexible filament for your 3d printers yes desaturated a different block yeah last week next up we have a great amazing ways to charge things yeah wirelessly these are the wireless chargers that adapt to USB I know these are weird so we're gonna have more photos of this soon because this is an unusual yeah I'm not seeing any other place have these how did okay I don't know what the heck they're really for but they're you know they're basically a little wireless key key charging modules these are receivers so if you have a charging plate that's like standard the key wireless charging standard these are the receivers this is what you put on the thing that you want to charge with your charging plate and they come in yeah see if you have a dumb phone that doesn't have the charger yeah it stick it on the back right and then you can make your own wireless charger on the line's on top yeah so I'm totally gonna just take advantage of your your kindness so what you would do is that was the last time you saw you have to basically get the one that orients properly so this one is oriented this way and then yeah you stick on the back and like now you have a key charging phone congratulations and then we also have a longer one and then there's two versions there's the forward and reverse so if you see this one it goes on the little us the micro USB connector has a little notch so of course you have to get it in the right way so check the images to make sure depending on each phone is different like sometimes it's forward sometimes reverse if you have a larger tablet type thing or from the side and you want to have it flip around you'll need this one so there's four options short and long and yeah they give you five volts out and you have to get the charging dish but they're available in the phone stores yeah I picked one up really inexpensively oh thank you all right it's great okay next up we've got drill bits drill bits we're also gonna end mill soon but the drill bits came in first we have PCB drills these are very hard carbide drills they're used for drilling PCBs that's why they're the little expensive they're not like cheap drill bits like one-eighth inch you know mild steel bits or whatever you get these are high-speed carbide drill bits and they come in and I still protect a thingy and we have them in point five point seven point nine and one point one millimeter use this in a dremel you can use this I use actually a dremel drill because the high-speed drill you do want to run especially to drill the PCBs which is what we use them for you do want to have them one little bit fast I don't remember exactly the speed but check out I did worry to tour about drilling PCBs and I think I just say like 500 rpm or faster I think is I didn't even want like 1000 rpm but look at the tutorial and yeah you can just use these in your little hand drill or if you have something the only thing is you know make sure that your drill is when you go down and go straight because these are very thin they'll break if it's twisted but these are hardened I mean your normal tiny drill bits typically break very easily these don't break terribly easily but I mean it is like point five millimeter with you know diameter they're they are fine just watch out like I we have ones that last us for like a half a year until like you bump it while you're drilling and then it cracks off but most part they're quite good well we'll have end mills as well soon okay people who want end mills these are only for drilling not for side to side action all right lady you got like three more products and then we are wow okay yeah this is you've wanted this for a while this is very interesting and when I saw this I was like what is that and I'm like oh I really like this and I'll actually set up a little demo hold on this is this is a laser break beam sensor do I have that right laser break beam sensor and it does exactly the opposite of what most laser break beam sensors do and I'm actually going to use this so here's here's what it is so usually and I'll what it doesn't do usually when you have a laser beam you have to have a sensor on the other end of the laser so this is like has a laser usually you have to have a sensor over here and then when you break it the sensor no longer senses the beam the light that would come out the laser and that way you know that the beam is broken so if you want to do like a laser break beam sensor problem is you have to have that that sensor perfectly calibrated like because the beam spot is so small that even on the other side like a meter away if you don't have like the sensor the photo cell really big and also like centered also can get dirty and so this is a little bit of a problem that you have to have something on the other side well this is a weird sensor that has a lens so you've got the laser diode part but there's also a lens with a light sensor and the light sensor is looking for the beam up to about a meter away so instead of having something on the opposite side you can it just uses this lens to detect the reflection of the beam so it just if it doesn't get the reflection anymore that it thinks it's right so for example here's the beam and then and then I just there's a trinket but actually not used I just used it for about power supply here so the beam is all the way on the wall over there but then when I put my hand it senses it that that beam is reflected off my hand and it sees that spot and then it says the beam is broken so I should make sure I don't bump it into anything else on the table so yeah as I put my hand in front of it it detects it so the only trade-off is that it has to be able to see that reflection so you can't use it we try a couple things first of all hands work great as well as anything that's like shiny and reflective if you have someone wearing a sweater doesn't work as well because the sweater doesn't reflect the beam of light it disperses it so you have to keep that in mind it also depends on the light levels you want if you want to have a good contrast spot but for many projects where you want to have a break beam this will work quite well okay all right next up we just put this in the store just a few hours ago this is the DIY gamer kit yes wow gamer kit it's a little DIY shield that plugs into a Arduino and it has a display you can play a flappy bird on it I think let me see what they I don't even know what this is this was build a while ago yeah so this is the flappy bird and then you press start and then okay I've already lost shoot let's go start okay I'm gonna really get a flappy bird apparently so yeah there's a couple games like pong there's like flappy bird there's snake and Tetris and other other fun games but honestly like I remember this is as good as the web version of the iOS what level are you up to candy crushing out well without paying you still haven't paid yet no I'm up to like four six years I gotta finish this game then I'm gonna get back to some engineering okay yeah cuz you've been really slacking off lately yeah it's a fun little portable game ones of a nine volt you can you know play games using Arduino if you want to have an Arduino project that's like portable and it has like an IR receiver and LEDs and it's I think it's just fun I think you do like multiplayer games even and there's a button in the light sensor so it's kind of like it it's a little bit of a explore but like with the display built-in okay lady the last product of the night oh yeah you got through it yep it is the pro trinket backpack yes so trinket we have pro trinket and pro trinket has a little backpack and this is a neat little what is this yeah this is a little thing that I know you've told me about many nights over dinner you said you know it'd be really cool is if we had a little power supply because then you'd be able to and then you would just tell me a bunch of stuff I don't understand okay so that with the pro trinket I've been noticing a lot of projects that people in building with trinket or or even pro trinket where they want to embed it in something portable and small so you want to be battery powered but then they also won't be able to charge the battery and it's so I thought when designing the pro trinket like maybe I should put battery charging capability built in but then like you know it makes a lot bigger and if it's connector and it adds a lot of expenses you know so instead what it did was I then the pro trinket which is like just the basics and then I made a board that fits on top and it's a little backpack so you can see it's it's it there's another board on top of it that gets soldered on and it has passed through pins and then you can plug in a lipo battery so I have this little 100 milliamp but you can use any size lipo or lithium-ion battery and as a built-in lithium-ion charger and like right now I'm charging it but when I unplug it the you can see the green power LED it's still working and so you can run your project off of a lipo and then charge it in when you need to plug it into USB to charge it or reprogram it and it's kind of free running so it's basically like a built-in backup battery UPS capability and it'll work with both the 5 volt and the 3 volt trinket 5 volt trinket you'd technically be overclocking but I've never found that to be a problem with a 3 volt trinket of course it works great the battery gives you 3.7 volts and it gets regulated down to 3.3 so this should let you do projects where you only have the micro USB port available and then you just plug it in to recharge the battery when the battery is low or to program the pro trinket you to program it in and there's also two pins on the two pads on the backpack that you can cut a trace and then connect to switch so if you want to have an on-off switch it has the ability to also be an on-off switch so you can charge it and then have it be off and then when you want to just turn it on and it'll run off the battery when it's on that's great for all kinds of wearable type yeah a little wearables project a lot of the trinket projects you did the only thing is that the pinout doesn't match the trinkets this is only for pro trinket but going forward I'm going to try to make all my boards use these three pins in a row so you can use it for any future board cuz it's a common question like well I like this valve or dev board little mini thing but I I want to add battery it's because these little lipo lipoli batteries are so inexpensive everybody wants to add them because it's like five bucks for a little battery now it's portable you don't You don't have to get double A's or triple A's. It's a double A. There's shields, there's capes, there's blocks, and now there's backpacks. Yes. Well, I mean, just generic backpack. I don't think I'm gonna have more than one. Yeah, okay, just one backpack. Okay. All right. Power backpack. And with that, that was new products. All right, whoof, you got through it. Okay. Okay, so. I know it over. It's fine. Anything that you saw that's in stock is 10% off, folks. Go ahead and drink it. We're gonna do one quick thing. Here's top secret for the night. Last week, we showed a little bit of a preview for Adafruit.io. It's our new Internet of Things service we're working on. It's in beta. We have another screenshot, and this is one of the real-time Adafruit.io things you can do, which is get data and look at it. You can get data, like the graph, and you can send data with the slider. Yeah. Ooh, vibrational. We can't talk more about it, because it's not out yet. It's not out yet. That's it. We're gonna do one round of questions. Okay. Here's a question for Mike. Special bonus. Because a couple of people had trinket questions. Okay, come in. So I'm gonna. Right here. Yes. Okay, I have a question before we go. Can you use the Adafruit trinket code with an Arduino Uno? Also, are diode-specific? Like, how resistors have to have certain amount of ohms to work for your project? So I think they're asking. So can trinket code be used on Uno? A lot of it can. Anything that uses timers, the timers are very different on the trinket. The pin numbers have to be changed. So like, the trinket uses pins zero and one, but on the Arduino Uno, you don't use those pins. Right. The analog code on the Uno and company, you can use like A1 to reference, but that doesn't work on the trinket side. It just used one, but it should work. You have to rearrange the pins, but the code in general works. Yes, and so a lot of projects for trinket actually did kind of were shrunk from the Uno, so it works, and then it goes backwards too. Like Becky would prototype Gemma projects on a Flora, and then once it's working, she would then, you know, and she made sure it was small enough, it would then, we compiled for Gemma. So that's pretty, that's a very common thing. Sure. Okay, and with that, we're going to do a trivia question. We're gonna give away something. Yes. Every type of trinket we have. Wow. And so that's trinket, three volt, trinket five volt, pro trinket three volt, pro trinket five volt. So that's four trinkets. You get four trinkets all together. I can't win because I won the resistor cross stitch. Oh yeah, did you like that? I haven't made it yet. Okay. I'm not a big cross-stitcher, but that's my lifetime, but I think somebody out in the audience. You also, in person people, I would be really sad if you're like, I don't need to wait a minute about it. So I have a nice hand answer. Yeah. So, as you can see on this screen. Yeah, so this week we're gonna, it's gonna be one where you have to post a link. So YouTube comments don't allow that, so I'm gonna do a Ustream one. So if you're in the Ustream chat with a ton of people, the first person to put the URL of Mike's book on the O'Reilly. Oh. The O'Reilly site. The O'Reilly site. So if you go to oreilly.com and search for trinket, you'll see it come up and just post a link to it in the Ustream chat and you will win all of those trinkets. And another special treat is, if you've won, when the book comes out, we'll also send you a copy of it. You'll just have to remind us. That's nice. Because we're gonna stock it in our store. Oh, don't forget, if you won before you can't win again. Even though you really want all this cool stuff. Right. We wanna make it fair. Everyone gets a chance. Oh, there's a hint. On the Adafruit site, you did post a link to the O'Reilly book. Oh yeah. Oh yeah, there's lots of hints. Oh, there's, all there is a hint. Hints, hints. Yeah, it's everywhere. Yeah, we're kinda done with the really hard questions because it's like nobody got them. Yeah. Okay. For BCG, you got it. Congratulations. Congratulations, you did it. Yay. Oops. You are the winner. Yeah, no. Did you erase everything? No, I didn't erase everything. And while you're there, you can pick up, if you pick up a copy of the raw book, which is nearly done compared to a lot of other raw books, they upgrade it for free until the final version. So you don't have to worry that you have an outdated book. That they give you free updates. So email supportedadafruit.com and you get a trinket three volt, a trinket five volt, a pro trinket three volt, a pro trinket five volt. And when this book comes out and we have it in the store, just send me an email later. Whoa. And we'll also send that out to you. Wow. When we have your book in the store, we're gonna have packs so people get the book and trinket and like, which is great. That is great. I like that. Yeah, like the first four projects or something. Nice. Okay, with that, that's the show. Mike, thank you so much for coming out. Thank you for having me guys. It's been a pleasure. Not only delightful with your tutorials, I'm online but in person too. Oh, thanks. I appreciate it. You guys are just the same. The good thing is cause I know that like, you know, you work for the State Department, you need to keep secrets. So I told you all the future projects I'm working on. I know. I've pulled my hair out that I keep secrets. Before we started the show, I talked to Mike about a very interesting business challenge that companies have. And I talked to other business people. I talked to other people that are in all sorts of walks of life. And it's a tricky thing when you have an online store and you take international credit cards and all this stuff. So I was just talking about like the world, the world's scope of doing business like that. Like customs and shipping. It's all very difficult. And there's not a lot of resources. But anyways, you're very trustworthy. So I feel like it's up to anything. I can act. All right. So thank you everyone. We'll see you next week. Tomorrow is 3D Hangouts with Matt, Noah and Pedro. Check that out. We have Ask an Engineer next week, 8 p.m. We have show and tell some 30. Most people aren't MakerCon, you said. MakerCon, a lot of people. And MakerFair this weekend. So if you're there, I'll be there Saturday. Saturday at what time? 11, I believe. In the morning? Yeah, I'm swimming. Yes. We're already at 11. And yeah, there's a tent for talks. Okay. So if you have tricky questions or you just wanna tell Mike what a great job you've done that 14 tutorials you wrote. Or if you, yeah, you have questions, just wanna hang out, I'll be around. But you wanna join the State Department. Okay. Careers.state.co. All right. Well, thank you so much, Mike. That was a lot of fun. Great. Okay, we'll see everybody next week. First, we have our, I have a new cat photo. That's Mosfet. Yeah, he's been in retirement. So this is him. Retirement? Yeah. And then. Yeah, he's had a long cat life. He's like 14 years old. Yeah, here is your moment of Zener. And as we end the show, I'm going to have the video of our new album.
