 mic pack. So thank you for stopping by. Welcome to you. And so does Fonzie there. Mr. Arthur Fonzarello, thanks for that, Todd. Thanks for stopping into our chat, people. We have a YouTube chat up. Dave Odessa is there. Beata Graf Alde Hagen. Johnny Bergdahl, welcome. Randall Bone, hello. Thanks for stopping in. And then over in our, what's this place? Discord. If you're somewhere that doesn't have a chat going on like Twitch or Facebook and you want to get in on the chat action, well, you could head over to our Discord, if that'll work for you. It is at datafrew.it slash discord. Look for the live broadcast chat channel. That's where all of the chattery is happening. And yeah, Randall noticed my silent movie there for a moment. That would have been fun. 40 minutes of mime. Are you ready? What? What are we doing here? Well, I've got a coupon code for you today. And in fact, I'll expose that right now because, hey, happy leap year, right? It is the rare. Every four years we get this day, the 29th of February. So happy leap year. And you can use that coupon code right there to get yourself 10% off in the Adafruit store today, good until midnight, tonight, east coast time. And all you got to do is type that into the coupon code slot on checkout. And that will work on anything you can buy other than conceptual things like gift certificates, software and subscriptions. It won't work on that, but it will work on actual physical stuff. Atoms. Buy some atoms from Adafruit. We'll send them to you and you'll get 10% off by using that coupon code right there. Leap year. Yes, indeed. Someone said it looks like the pie shortage is over. They've been in stock at the Adafruit shop for over 24 hours now. No kidding. Is that the pie five that's in? Let's go look. Because that coupon code, that'll work on that, pretty sure. So look, here we are. This is Adafruit.com. I'm going to say raspberrypie5. Look at that. You can get the eight gig model. That is in stock. Amazing. Yes, it's been in stock for a day now. That's great. So you get 10% off on that. I don't think there's any exclusions. So that's a deal, right? Go get yourself a raspberry pie five. What are you doing with these things? These things are beastly performers. What are you getting up to with them? It's not just a credit card sized computer that doesn't do much anymore. These are very fully featured. They always did a lot, I shouldn't say. But yeah, that'll get you 10% off in the store so you can pick up a raspberry pie five, eight gig if you want. It says it's $80. It would only cost you $72 US before tax shipping, etc. So that's coupon code. Today is the leap day of the leap year of our leap month. Everybody leap. What else do we have? I will give you a little recap of the product pick. I've got a circuit python parsec for you that I'm super excited about. And then I have a few things. I've got a little project trial I want to do. This is on one of Liz's projects and I got it up and running in a matter of minutes today and I just wanted to show it off because I think it's super cool. What else? I have a little gear report I want to do on some cool little lights I've been using, some small point light sources. I'll show that to you as well as some lighting concept. I'm not just saying go buy stuff. You may have lights that'll work for these kinds of techniques. So I'll show you a couple of little neat lighting techniques that I've been using as I take some miniature photography and do some stop motion animation and some similar stuff. What else? I also have some WLED stuff. I have never really used WLED. I think this is maybe the second time I used it the other day for actually you'll see it in the product pic here and I wanted to go over that process because again it's a pretty straight forward process. If you haven't tried it I'm going to do it from scratch on a QDPI ESP Pico and you can see what's involved with getting the WLED up and running. I think that's it. I think that's what I've got planned for you here today. So let's kick it off with a sip of water and then you know I've been smart. If I'd popped that on muted the mic taking my drink of water like this and you never would have known perfect crime but I didn't do that. I did do this. Check it out. This is my product pic of the week this week. Here's a recap. The power BFF and we have the Neo RGB stem up. I have the QDPI plugged into the power BFF. Power BFF is mounted to one of our little swirly grids. I have a 12 volt power supply plugged into the power BFF. That is supplying power to the QDPI, five volts that it needs, power and ground from the power BFF over the stem of cable to the Neo RGB stem aboard and the white wire there is actually running to one of my GPIO pins so that is sending Neo pixel signals. It thinks there's a Neo pixel there but we can see this happening here is my RGB strip is plugged into the red green and blue and common anode lines running through color fading demo a single color and now we can go through and just set it to individual colors is the power BFF for QDPI and the Neo RGB stemma. Yes indeed. So go get those. Those are cool. I know the discount only applies during the show that if you if you're able to tune in on Tuesdays during that that time you will you will be able to get yourself the big huge discount but you could use today's discount code which I mentioned is leap year. You could use that on those. In fact let's hop back over to here it's power BFF. Let's see if we got in the stock. Yeah so those are 795 right now. We have 18 of them in stock so we sold through boy we sold through a slew of them on the show that's great. That is it right there and I'll be showing that today. I mentioned this I think during the show I love having mounting points the the mounting wings there on the side of the QDPI shaped board are fantastic particularly for this one. This one has big stuff plugged into it moderately high power that kind of stuff so it's nice to be able to affix it because normally you know QDPI that's got no mounting points on it so you have to bracket it and snap fit it with 3d printed parts or adhere it somehow. So that was the power BFF and then the Neo RGB also in stock and that should mean when we say in stock and don't give a number I think that means we have over 100 so anyway those those are a neat combo. You can also pick up a 12 volt power supply something like this 5 amp switching well that's out of stock right now. Do we have yeah I don't think we have that many 12 volts it's either that or the 1 amp but I think you'll want a higher current than that. Depending on what you're you're driving you can you can use different power supplies for different things. One thing that was mentioned actually on the show on Tuesday someone said hey what about using nudes which are our noodle led strips we have let me jump back over to that 12 volt nudes are the medium sized ones right here. I think we have a longer one that's 20 volt but these are the 12 volt ones and they come in a few different colors you could kind of roll your own RGB experience with a red one, a green one, a blue one and then put each one into a different channel of the Neo RGB and then you're able to talk to it like it's a neopixel you can you know do color gradients and things like that that'll pass their way through the three different nudes so kind of a cool idea. I think that might have been DJ Devon 3 who came up with that asked about that on the show so loved that idea would love to see see that in action so that would be a kind of other neat use. Love the idea that the Neo RGB lets you use the ease of all of the neopixel software out in the world there even though the thing on the other end of it is analog sort of dumb strips I don't mean to insult okay uh hey let's do a circuit python parsec next hey okay uh so for the circuit python parsec today I want to show you how you can create user interface buttons in display i o using eta fruit button library so this is a pi portal I have here and this will work pretty much with any of our displays that have some sort of a touch input this can be a resistive touch like this one can be capacitive touch and what we're trying to do here is create user interface buttons it's something that's pretty common to want on a touch device like this and rather than roll your own with uh sprites or with tile elements um and then text labels on top and checking states and swapping them out for different colors this kind of makes all of that really come together for you in this high-level library so you can see here I've got a couple of buttons on here when I touch them this is resistive touch so I can use this stylus to get my finger out of the way there when I touch them they are reacting they're also printing out to my repel there when they're getting pressed you can also see when I press one and then leave the button it knows even though I'm continuing to press so I'm sliding onto those which is pretty nice all of that is functionality that comes inside of Adafruit button so here's how this works say that again so here's how this works I have imported from Adafruit button the button library I am setting up a button right here so you can see button one is button and then I give it a whole bunch of parameters how uh where it's positioned so x and y I'm moving it 10 over and 10 down the width of it I'm choosing a division of the width and the division of the height there but you can just give it a pixel number if you want the style of it we can make rectangles round rectangles round rectangles with shadows and rectangles with shadows we have different colors here so the fill is the sort of meaty center of it I'm giving it this kind of dark purple outline is this brighter magenta I've told it a label which is a piece of text you can use terminal IO font or you can be fancy and pick a bdf bitmap raster font like I've got here lotto bold and then we have colors for the label as well as different colors for when things get pressed you can leave those off and it'll just give you sort of a inverse of the color or you can get fancy and pick specific colors I've set up a second button here I'm adding those to my display group and then I'm doing some state stuff here so I'm not constantly spamming then this is all touch stuff here in the main loop I'm just checking for a touch screen touch point if it does get pressed then I can check this is really slick if the button contains that point that coordinate point on the screen that's how it knows that it is being pressed so if you make a real big button if you make a real small button you don't have to really care about that it knows if that touch point is contained inside of the button or not and then when it's got a press when it's being pressed we're doing one thing when it's being released we do a different thing and then I've got that running for a couple of different buttons there so there's a really nice and easy to set up we have a bunch of examples in different learning guides Brent has some really cool learn guides that use these as lighting controllers go check those out and so that is how you can use Adafruit button to create display IO button elements inside of circuit python and that is your circuit python parsec all right I pulled it off that time I drank the water while while that thing was playing so you don't know that I drank the water oh Yanisaku says it should be Lars Larson you're right that Lars is hey look let's let's change that here's how easy it is you won't be surprised how easy this is I'm gonna say Lars Larson save you actually connect that you are and there it is Lars Larson and that is buttons in action for you let's see other questions oh yeah I'm you know what Mike P asked about the the nudes and the colors I think I misspoke let's look at that again if you take a look here we have let's see yeah the 300 millimeter ones are three volt and the 1.2 meter long or the 24 volt so yeah this this 600 millimeter long one that's the one you want if you're going to do the power bff and neo rgb with 12 volt you could do can you give it three I think you can I think the uh got one right here no okay minimum of five on this you'd need to add some resistors so yeah I would say either wait because I think we have some other colors coming in stock or go for a shorter one and use some resistors to divide that voltage down so you can use a three volt nude with the five volt output of this or you know depending on your current you might just skip this all together you can still use the neo rgb there that does three volts to 16 volts so that on its own would would work well for those shorter nudes okay let's see next up uh how about let's dive into this wled thing so this is uh let me jump over to this page here uh and to set this up um wled is an alternative to using the neopixel library in arduino or in circuit python or fast led or fancy led it's another way to talk to neopixel style leds with uh different code this is an open source project and the um w and wled I believe stands for wireless because this is all about using uh the wi-fi built into esp chips to control your leds using a web interface of some kind it can be an app on your mobile device it can just be a web page um so here I've got one of the esp 32 cutie pies so that's I think sometimes called a pico um and I'll let me bring one up right here so esp 32 cutie uh it is this one here um yeah so it's called pico confusingly because every fifth thing in in microcontrollers is called pico but this is yet another one uh so esp 32 pico that one uh is the one you can use for this project works really well um and let's uh let's set this up so I've got I don't know what's on this one I picked this up out of drawer soldered some uh headers onto it and not really sure what's on it but I've plugged it in and then from this install dot wled dot me uh it says plug in your esp to usb port hit install and then we're supposed to pick from a uh a screen you're not seeing sorry the usb serial port in this case it will always have a w on the mac at least a w in front of the the part of the name and that's I think in Erin has a couple of different guides that she's done using this so that'll let you know how to find the right one out of a list of multiple ports uh so it has found it uh you can see there says install wled logs and consoles also installed wled uh yes uh it's erasing whatever was on there hope it wasn't important uh this will take two minutes it says uh we can watch that uh crawl through there what we'll do after that is we just want to get onto a wi-fi access point so I have one here I'm actually going to take my phone right now and get onto that same wi-fi just because I'm not normally on that one so let's go pick the shop wi-fi and join that that means uh with the esp 32 on that network and the device I want to control it from on that network it should be able to connect pretty easily the device itself has the settings sort of served up from here so we're able to grab settings that live on this is this kind of the only two things you need there's not like a computer in the middle serving things up hosting things it's all a little page on here that we'll connect with dava desa asks does the web installer work in firefox I do not know typically I use chrome for for these kinds of web usb things and I'm not sure where firefox is in that okay so installation is complete hit next and now with it still plugged in over the usb it's going to allow me to pick a wi-fi network I'm going to move this off screen for a second because I think the password might be in the clear and oh it's not okay it's a bunch of dots this password is a bunch of bullet points what the heck okay so back there okay so it connected to the networks that's great so now the esp 32 cutie pie is on the same wi-fi network that I got the phone onto um and we can go to visit the device uh the I think now this computer's not on wi-fi it's only on the wired network but I think that still works they're on the same wired uh same network wired and wired um so what we can do now is go in and change a whole bunch of configurations like uh which pin are we connected to for a neopixel or in our case we'll use the neo rgb to pretend to be a neopixel so let me grab this is the setup I had the other day except I'm taking the esp 32 off of this so we can do this from scratch and so what I've got is this 12 volt uh five no two amp 12 volt two amp power supply switching power supply I'm going to plug that in to a power strip um you can see it is now sending power through my power bff to the little neo stemma um I'm gonna unplug that you know plug my cutie pie in there and then I'll replug that 12 volts in so you can see I'm still connected over usb I think I can disconnect that I'm going to switch to a uh view you can see a little more easily on the down shooter now so give me a moment to set this up that view like that and you know what I'll hide uh I'm going to pull this camera out a bit so you can see things there we go that should work and a couple camera adjustments whoops that's exposure I want focus good all right so now you can see here um I have one of the pins on the bottom here connected to this white wire so it's on the bottom of the power bff but it's actually just a pass through of one of the cutie pie pins that's where the header was soldered in uh I think I have that on a zero or a one I think it's I think it's a zero we'll try that so that's what the data signal is going to go out to the neo uh stemma on so I'll say this is a one neo pixel uh the GPIO pin is oh okay oh wait do you thank you someone just told me we can't see what I want you to see sorry I didn't press update there we go uh sorry about that thanks for the for the warning uh okay so you can see here uh the type of neo pixel uh or rgb pixel selected color order will mess within a second once I get this working here's the length I say this is just a single neo pixel essentially um and then the GPIO pin that we're on what I'll do is let's go back to the learn guide for the cutie pie esp 32 and go to the pin out and then we'll go to this nice chart here that shows us the sort of silkscreen name I think I'm I think I'm soldered to a zero and then in yellow here is the sort of a actual GPIO pin name you can see it in yellow there so it should be pin 26 that I want to tell it to you so I'll say pin 26 oops nope I'll say pin 26 there we go uh and the rest of these are going to leave to defaults and hit save now go back and you can do all this from the phone but I realize this lights you're free to see um and let's see will it work all right let's try problem is I can't see very well which pin I soldered you to maybe you're the next one yeah I think you're on a one okay so let's go back here a one is on 25 it's GPIO 25 so we'll go back to config led preferences and 25 save go back uh oh all right why are you not letting that let's give you a reset gonna give you a reset sure and you know what actually I'm just going to confirm since this one is on wi-fi I'm going to go to the WLED app on here and try that same make sure those same settings are there so here you can see this is loading the WLED UI power cycle that whole situation there uh oh it can't be reached hmm all right let me make sure this stayed on that network it is okay let me forget my other network so that should work uh because that is the proper I'm on the proper uh device okay so what let's see what's what you are powering it it's either of those two hide this let's go back to config wi-fi setup good and config led prefs I'll try this again with that uh GPIO and then I'll I'll maybe pull that off and confirm that's the one it's on okay that's a mystery let's do actually one other thing just to make sure I haven't like jiggled a wire I'm going to plug in the uh USB 32 from Tuesday that I know is working okay good we have we have light put this one back in just because I'm stubborn I want to see why it why won't you work oh I guess I should have checked yeah let's check what what that other one what pin it's on I can still look and figure there rather than unscrew that from the board uh so you can see here on WLED it knows that I've used multiple devices uh one of them I named which is this one I named it analog neon so I think it's trying to come online right now you see a little spinning network stuff Tyath asks a good question the color order is probably wrong but I think we would get something um I can mess with that too but yeah right now none of these are coming up which is a little strange plug USB in just for yeah some of those should be coming up let's quit the app and relaunch it I thought this was the one named analog neon and it was up a moment ago any WLED experts in the chat let me know if you have a idea of what's going on here are you all offline and the light failed check the IP address yeah I think I've got yeah I don't know what uh where it has gone where have you gone thing so let's do this I'm going to plug this in go back to the install page which lets you um if you already have it installed confusingly it's still the install button and if we say connect it'll just go to the config so let's read you oh my huh my network's not showing up uh I can't reset that or we'll lose the live stream that's the same router that everything's going through very weird what are you called okay well that's showing up now I don't know what was up but okay so let's see if we pick this one give it power okay so that one works now but that's not the one that I set up new um yeah Todd bot asked in the chat could the new one you set up be stealing your setup now let me put this into do not disturb so we don't get texts on top of things huh do I dare well you know what I won't do that we'll pretend that that one worked this is uh this is the one this is the cooking show style this is the one from the other day but if I get this out of the way I can unplug ostensibly from the power there or is that my key to my problem there is the network is it not really on wi-fi okay well it looks like it's working okay um sort of working so we'll we'll plow forward uh so here's what you get and this is the same pretty much in the phone app or uh from a web page which is nice because you can you don't need any specialized equipment as long as you're on wi-fi with something you can connect to uh the sp32 and control your leds now uh typically you'll have a a lot of neopixels so you can do you know lighting effects with them run comets and things like that this is acting like a single led but that's still kind of cool so uh if you look down at the bottom here you've got effects and colors and then there's a more advanced thing using segments as well as saving yourself some presets uh so on the colors page we can pick uh brightness nice separate of hue saturation value this is a slider that goes through your saturation uh or you can just pick it on the color wheel there you can also pick some preset colors uh rainbow I think wants to run a rainbow across your strip so it's not quite sure what to do with a single single led like we have in this case but the kind of more interesting stuff is when you head over to the effects tab down at the bottom here uh so right now we're in solid mode uh you saw earlier I did blink um here's a color loop is kind of nice so this allows you to loop among different colors that you have in a gradient palette so I'll go pick from now you can see instead of just single colors we have these these palettes so here's one that goes from sort of a green to a pink and if we go back to the effects you can we're doing the color loop through that that sort of gradient of a few colors but we can do things like change the speed of the effect so slow it way down and now you can see you get that nice soft transition between colors and then the saturation of whatever effect you're doing you can also say you know I want it to be a little subtler even though I have a set of very saturated colors picked over in my gradient palette I can say let's tone that down with the saturation control which is really nice it means you don't have to save a zillion different gradient presets if we go to full 255 this is going to use the full saturation of your gradient palette and what else uh what else is there there to say I think that's that's the main stuff and then you can see here you can pick from from different presets play around with different colors that's sort of the main usage and that's pretty much as far as I've gotten there are some other neat things you can do like put things on a timer right now it's going to turn off after 60 minutes so you can customize the timer you can have multiple of these synced to a single source so if we had two of these running 10 of these running however many of these running if you hit sync it'll put them all essentially on a it'll sort of restart their gradients that they're going through at the same time there's probably going to be some slippage over time there because there isn't a crystal with compensation keeping the time real time clock I don't know if that's a possibility or not I have no idea what peak and info are info I'm guessing tells us yeah some mac address stuff the wi-fi signal strength that you're getting up time etc so nice nice stuff to check out if you have a big installation kind of stuff that Erin does in her tiki bars and things that could be helpful you can see you also always have a brightness slider up here at the top which is nice if you just need to calm things down and I think that's it I'll quickly run out of things that I know about this so but you can see it's very very friendly to play around with um and I'll leave it at that I'll probably play around and see what what I was doing wrong with uh with this second one here I'm sure it was just some goofy user error but that is this running on uh on the little neon style strip oh the one of the thing I wanted to do is um since tyeth mentioned this is to talk about um the color order so if I go back to solid go to colors go to red uh you can see it's giving me red that's good if I go to blue is it going to be blue or green it is blue okay so I have the correct color order um if you look over in this config under led preferences you can pick different color orders which uh you've got green red blue that's pretty typical for a neopixel these days I think GRB or GBR one of those I can remember which um but you've got kind of all the combinations of which order the pixels are in it doesn't really matter with this stemma uh because we have separate wires coming off of the analog strip that you can plug in I actually have mine plugged in uh what blue red green instead of blue green red um so if I if I actually plug those in correctly I would then need to change this order to match match that but just so you know there's a there's a couple places where you can make that change if you're using the neo rgb and you have an analog strip um so any chance you got a power meter to see what it's using uh max current power I don't have anything easy to hook up uh here right now I don't think yeah take a bit of a setup but uh yeah that that would be a good thing to to test if you're doing a larger installation to make sure that you have the right power uh power supplies and yeah you can see here there's also some things like enabling automatic brightness limiters so that if you head towards white it can calm things down and not uh not go past your your current draw that you uh are prepared for I I think I could go brighter than that this is a 2 amp supply and it's being limited to 850 milliamp right now but I won't I won't test that and burn the place down right now okay so that uh is my WLED thing thanks for hanging in there with me as uh as I goofed around with that uh so let's take that off here uh the other thing I won't I won't do this right now the other thing I was gonna show is that one nice thing about this setup uh is that you've got a stemma cable uh you've got this stemma cable here and so that's my data on the white pin coming essentially from that uh GPIO pin and my power and ground which are coming from the terminal blocks that's passing the 12 volts through basically um with my strip connected to this Neo RGB I could grab this other one I have another one over here uh that I used for sorry slappy that I used for a different demo um it too is a analog strip plugged in to one of these so I could swap that in fact let's do it let me bring the camera up here so this is a separate strip but it's got a three pin stemma connector so I could just click that in there uh and give this power again and uh there we go now we're lighting up a different strip um which I have plugged in a different order so we're definitely gonna get different colors I have green red blue plugged in on this one uh so that's a fun little way to swap these out if you're testing or doing some setup uh is with these little boards I really like these all right enough of that let's put that all away and by the way I have some regrets here of unrolling I'm gonna re-roll this spool the uh adhesive backing uh protection film on this is starting to come off as this has been unwound uh and I really don't want to lose that with dust coming in there so I'm gonna re-roll this since that backing does not flex it uh I think has a little bit of a memory of the spool shape it was in and so as that stuff kind of lifts off you can see there you kind of want to stick it if you're if you're planning on using it if you have a cabinet or something you want to stick it to or a ceiling or something you kind of want to use that before you leave this unspooled for a while because they just sort of peel off and get dust and things under there so the problem is deciding it's kind of like stickers it's deciding am I going to use this where's it going to go uh DJ Devon 3 says you could plug in a usb meter between the usb cable and the cutie pie I think that would not tell us the power consumption because of the DC power supply with the barrel jack is is what I'm running them off of if you're trying to check that if you're trying to check the power to the strip all right so that one I'll weave like that so we don't lose the stickiness there okay next up it is cat printer time so I promise this is a this is a liz project that I think is super cool I'll do this one here too actually so let me give you the down cam and the me right here so this is a little bluetooth thermal printer you can pick these up on the internet pretty cheaply Liz has a guide I'll show you that in a second which tells you the specific one that that she has that's working well with this printer software and these are I think this might be are you on and connected no it probably turned itself off okay so I'm turning on the cat printer um here is turn off and on this is a memento running the arduino software that Liz wrote for this which comes in a convenient uf2 file that you just drag over and what happens is it's it's starting up and I think it's connected already I think it just connected to the the cat printer nothing's blinking there nothing's blinking here I think it's connected so what we can do is take a picture and oh wait it's now it's saying connecting all right I don't know what was doing before now it's trying to connect uh connecting okay presumably it's connected we'll try uh oh did I hit the reset I think I hit the reset instead of the yeah I hit the reset not the uh take a photo button all right try again yeah so took the photo is printing yes shot on memento so this is uh as you can see here a dithered one bit image which is pretty much how the gameboy camera worked as well uh and it makes this printer happy this thermal printer is happiest with this type of image works well uh Liz has a great write up about trying different things grayscale vmp's and such but this for one bit image where there's a uh dithering algorithm that sort of simulates uh grayscale by putting little dots close together gives you this really nice look it's tricky to peel those tear those off quickly enough and there we get shot on memento let me try to let's focus this a little closer there we go shot on memento who could need more resolution than that I don't know uh there's also sticker paper and and colored paper that come with these but it's a little thermal thermal printer roll uh that goes in there so there's no um ink or anything like that it simply uses heat to transfer um this image onto here uh I have not tried these in a long time so I don't know if these sort of fade and turn brown and the paper darkens and yellows over time like like in the old days with these kind of printers but I suspect yeah um we'll see I don't know if Liz if you if you're still there if you've had experience with that um but that's uh that's pretty cool so we can uh let's let's take another picture over here while this I'll see if the the range is enough and let's turn this around that's actually how the comes out I'll take a picture of my um mannequin here it says printing on the screen there and there's my little stop motion friend da da da shout out memento I love this super fun great party trick if you if you want to bring a memento and a little a little printer with you these are distinctive and low low fi low res a lot of fun there um this is let me switch over to see that yeah uh let's see back here learn this is kitty printer at printer okay there's one here it is ble cat thermal printer memento we have a couple it looks like Jeff Epler did something with these two uh so here is Liz's guide um I don't know if this has already been recapped uh on on a live stream before but I'll just uh go over the uh the pertinent bits here which are uh what you need there's a link to the printer here's the software you're just going to download this memento cat printer uf2 and then with your memento plugged in double click to get into bootloader mode drag that on and you're done um you could uh I think there should be a link to the arduino here's the code right here yeah so there's a there's a download file there if you want to get the arduino code and mess around with that uses this cat gfx uh library with a little link to that uh and then there's a nice uh here's a little how-to to get set up with some nice gifts in there uh get up and running which you saw that worked there pretty pretty painless uh and then there's a nice article uh or write up on this page here that Liz did of um the the process of getting this to work uh which is a good read so go check that out but uh for me it definitely satisfies the urge to get an old um game boy camera and game boy printer without having to go bother doing all that and um no double a batteries it just has a rechargeable lithium ion built inside so turn it off and we're done so go check that out thanks liz for putting that together and making that so easy to use all right let's see last up is this last up yeah last up let me head over to the bench here there's that uh mannequin you just saw me little stop motion puppet you saw me messing around with um and i'm gonna actually before i go over there i'll show you here's what i want to talk about which is this um cool little cube light that i got um there's a bunch of different brands i'm not pushing one in particular um but you'll see these where are you this one is from small rig who make a lot of good but not too expensive uh camera and lighting gear um it is a little i think in this one it's a three watt led um single color i think this is a daylight temperature like 5600 kelvin uh inexpensive built-in uh lipo battery turns on and off with a single button has a usbc port for charging um but the nice thing about it is that it's a super tiny light source which if you um look at let's see let me point this other camera for a second if you look at the main light that i use to um light up the workbench and me for doing the shows it is that it is a big big spot um and i have a big diffusion umbrella on there reflector uh honeycomb grid on it to keep the light from spilling so it's a big whole big production whole big thing um and they're great for a lot of things but one thing they're not good at is hard shadows on small objects so when you're shooting little product photos when you're shooting stop motion stuff little animation things um it's kind of nice to have some really tiny point light sources because it gives you hard shadows if you want them but you can also sculpt those shadows um put gels in front of them put barn doors on them to to shape them uh diffuse them if you want to um but they're nice and small and i'll turn this on you can see there that's the lowest brightness just got four brightness settings big big so you can see it's a lot of light go down the lowest one um one of the ideas behind these is that you can put them on top of your phone with a little um rig if you have one of these type of iphone camera mount type of things i use one of these things when i put an iphone on a camera mount and you can hook these to the little cold shoe connectors there so you can get a little light there that's like maybe slightly off to the side but uh they're not great because they're a pretty tiny point light source they're a bit harsh and hard and frontal on faces um so i don't think they're as good for that as they are for using like little lights that you can position around a scene um they come with some gels like i said um they come with this little silicone diffuser dome and they come with a pretty useless honeycomb grid and a pretty neat little barn door as well as a little snoot which is used to give you a round sort of round spotlight on on a little subject uh i just have a couple of these you can also buy kits that come with three of them and that's maybe a hundred bucks they're not that much i think individually so like thirty dollars um these will come with tripods and all the accessories for all three in a little cute bag um so what i wanted to do though is show you in action why i think these are cool so let's hop over here and put me in the corner there so let's move that out of the way there we've got our little mannequin okay so right now he's been lit with a whole bunch of um the lights that i have in here including that big spot that you saw here is if i turn on the overhead right so this usually doesn't look so good for these little little scenes to have these big lights so bright overhead bouncing off of stuff so to to get things a little more sculpted what we can do is take one of these and i'll just show you some of the differences so here is just the raw light very hard i'm going to turn up the brightness on this so very hard light which you can see on the face there i can get some nice hard uh shadows which is nice but it's also kind of everywhere so that's why these these little accessories are great there's a magnet clip thingy on the front that's okay they're not very strong magnets magnets if you bump these everything falls off which is a pain but so here's a typical set of barn doors let me turn the light off for a second um so this is this goes back to the origins of film lighting uh stage lighting and film lighting is the notion of having some flaps to control where the light is coming out so if we open these all the way up turn this on uh you can see it's just as if it's not there but if i want to let's say get some of that light off his chest i'm gonna you can see my finger there i'm gonna raise up that bottom flap i can close the top down to get some off of the back bring the sides in you can see it's now coming away from the the background a little bit so we can pop them out better uh whoops and there you go the magnets uh so if i point this at the at the backdrop you can see we get kind of a nice rectangle now using that um so that's useful um it's a little bright let's bring it down so that's pretty useful for for getting some light on this guy um if we bring the light around a bit we can light his face without hitting the background so again without the barn doors and with now we can light him and we're not lighting the background which is pretty cool um what i'm gonna do right now just so these look a little um clearer i'm gonna drop out my spotlight and i think i'll drop out this side light here so now he's got mostly ambient light so so what i do here you can see a little better all right so there's our little barn door on there pretty nice you can stack things like bring in a gel bring in so here's a here's an orange gel without with you can see that that drops the light a bunch um but now i've got raise the level there now i've got a little warm light hitting him there um we could take a second uh one of these little lights i've got one on a tiny tripod over here turn this on and i'll put a little blue in front of it and i'll just hand hold that uh let's go brighter so now you can see i can put some blue maybe behind him and some orange in the front of him so now it looks like every movie poster from about 20 2007 onward or so uh get that orange and orange and teal kind of look to it uh or we can hit some orange in the back and some warmth on him which is kind of cool uh the i mentioned i'll turn this one off i mentioned the little uh snoot is cool because you can see that gives me a round uh little beam there and that's helpful for picking out if i want to get a light on his face and not hit his arm this is basically tighter than the than the barn door great for picking out little details so that's that little snoot there similar to a flashlight uh it just has a bit of a nicer cleaner beam to it the spot is pretty fairly even uh the other let me pop this thing off the other one that's uh nice for some situations is this little diffuser so if you look at his shadow back there without and with right so there's a there's the raw beam and there's with diffusion brightness all the way up well two there we go so he's you know he's it's gonna cut light you can see how bright he is without it um but it's a nice diffuse source we can get on there and the shadows aren't as harsh in the back so if we want to control those with the barn door you can still get those nice hard shadows turn the brightness down uh that's about it i said it comes with a honeycomb which you might have seen i have on my main spot there um that just makes it a little more directional so that prevents some spill uh from coming out the sides of a of a reflector like that but this one i think is it just needs to be smaller it doesn't really do much to cut it um you you know you should see not a lot of holes when you go sideways so with a tighter grid or uh maybe thicker this way and tighter grid honeycomb will cut a lot more light than that this one is i just don't think size appropriately so it'll this will take like really oblique angles before it cuts much light so this probably should have been tighter on this and then here's a little cold shoe attachment that you can use to put it on top of a camera or or other piece of gear just mounts onto there and then that slides in lock that in place i don't really use that but having little weird little tripods around is helpful um one other thing sort of not related to this particular light or um this will work with a big light a small light kind of a neat technique for upping uh your versatility of lighting in cases like this is to use a little mirror so i've got little inexpensive sort of flexible mirror here with a bunch of thumb prints all over it uh these have i think an adhesive backing on them but i just i just clip them into uh clip them to things um but what this does is it gives you uh abilities to cast a nice square or rectangular um reflection which will look like light streaming in from a window uh from a skylight so you can see that's me pointing the light back at myself and then using the uh i can point it at the camera there to signal you uh that gives me a nice nice look of a window so it's lighting him you'll probably want to add more uh light to him if you're if you're this far away to get the shape that you want uh and you can also turn this off um you can also put blockers on this so if i grab some uh tape we should be able to put some little um window shade or window panes into here let's just do a cross through the middle of this so you can see i've just put a little plus pattern on there all right so now i get morning uh sun streaming in our in our guy on our guy here uh as if we've got obviously want to lock these things down so that they're not all moving um and i use these kind of like these very flexible and i have a magnet uh on the bottom so i'll clamp that like so let's get this here there we go yeah oh now now we have that um giving some of the lighting onto him it's some of the lighting onto the backdrop there and then i take another light and uh fill in on a space with this little snoot here oops all right so you can you can match the angle uh of the the reflected little mirror light there so it looks for all intents and purposes to be the same light source but you can see there's without and there's with that little snoot on there and the nice thing is that with that if i if i take that off i'm lighting uh way too much light and i'm lighting all of him um if i kind of want to cheat and emphasize his face there then this is a nice way to to cheat that so again i'll clamp that onto a little tripod and and leave that there uh and this works great for memento lighting i've been using this kind of stuff to to shoot little scenes um let me see if i can if i can hook this light to another another one of these little flexi guys there uh and let's see if i can take a better quality uh gameboy cat printer photo let's see and to get a little bit meta let's put the cat printer into the scene printing i feel like i should take a second one with the actual print in there seems seems like the right thing to do uh you can see also by the way i was able to move i can put this camera really close to him and i'm not blocking the light on his face because i'm using that little point source uh if i if i took a bigger panel like uh where are my little panel lights going off to i was just looking at one there's one over here but i don't want to take that off oh panel light are you that's mysterious oh here it is so this this uh little panel light here this is a nice diffuse source but it's it doesn't have barn doors on it does not give me sharp shadows uh and it's a big enough source that i probably start casting shadows around if i put my hand in there uh so let's take a look at these grab our printer uh these little lights by the way um i think luma cube were the the original ones these are kind of a knockoff of that and quite a bit cheaper um luma cubes are like 80 bucks these are closer to 30 they have around a 45 minute to an hour battery life on full brightness so you do kind of have to uh and i don't think they run while uh while charging so you do have to be mindful of that can you take a picture of the printer printing out the picture it's taking i think i think we have let's see let's see how we do uh let's jump to this view there it is not bad not bad it's better than the original was the question yeah his face is more distinct for sure nicer lighting i think and look we've got a little scene there with that morning light coming in through the breakfast nook or whatever um all right that is my little uh lighting thing there i hope you enjoyed that let me know if you have any questions uh in the chat uh the dpi of the printer that's a good question uh if liz is around do you know uh i can let's go back to her guide for a second and i'll check the link so if you go to the overview here internet famous billy cat thermal printer cat gfx library billy cat thermal printer okay this one happened to come from amazon um why do i suspect it won't say 203 dpi is their claim maybe you could probably count the dots on this if you took a took a took the right photo with the gameboy printer uh more like inches per dot done done done okay that's gonna do it then uh thanks everyone for stopping by today uh i am uh i think gonna be i think we'll have maybe scott or foamy guy on tomorrow with a deep dive um not sure what the plan is but you can check live broadcast broadcast chat live broadcast announce uh later in the day or check our blog and see uh we will be back on tuesday when the product pick uh we have three hangouts on wednesday we have show and tell wednesday evening ask an engineer after that um hope i haven't missed anything but a whole bunch of live streams as well as great content learn guides uh don't forget to check out our playground section in fact i want to there's something i want to check right there there was a um there was a update that we get there data fruit what's the what's the we have so many things called playground is it playground dot eta fruit this should be easier to find you can't google this we have too many things named playground oh is that it no this is embarrassing all right someone in the chat tell me because i was seriously can't find it i'm not leaving until we find this data fruit dot playground is that not the name of it what's the new bloggy thing i can't remember data fruit playground not products not that no eta fruit dash playground i never would have come up with that all right uh that's embarrassing thank you mike p zero four five one eta fruit dash playground uh yeah don't don't forget you can go here and post your own uh guides learn guides journals progress findings um always lots of good stuff in there so if you're looking for interesting things that are going on uh these are uh lean and fast and uh you can get a lot of good info from these and uh i will bookmark it you can get to it from learn okay thank you let's let me see if i go to learn is there a link here i bet there is no i bet if i i'm gonna stop embarrassing myself by searching for things just that just remember how about i remember eta fruit dash playground go check that out uh oh yeah in fact uh c grover is working on one right now that is uh wavestore creating a library of synth i o voices uh amazing stuff go go check this out uh it's it's happening right here last updated today this is real time at the top of the burger menu i'm not signed in so maybe it won't let me do that all right that's it for me uh thanks everyone for stopping by i will see you uh in the future soon so have a good rest of your day a good friday a good weekend and we'll see you next week
