Make a RepStrap Robot (Part 2) - Weekend Projects Podcast

[crrider12564]

Very cool. Chaeck out my giant killer robot project vids

[Chwyn]

yeah cuzz i can do this is a weekend..

[vincentstockdaletv]

the pen idea is pointless because people have already done that its call printers

[demjp8RqDA]

@vincentstockdaletv Not necessarily. Say you want to prototype PC boards. With an X-Y-Z platform and a sharpie you could directly lay down marker ink onto a PCB. Marker ink works well as etch resist. You can't put a PCB into a printer AFAIK. There are toner transfer methods of doing this but they're clunky and the good transfer systems are a bit expensive. I've never had any luck with the cheap or free ones (like using magazine paper).

[vincentstockdaletv]

@demjp8RqDA okay i see what you mean and i like ur example of pcb btw i was having bad day when posted didnt mean to sound like a smarty pants

[shaunh88]

you lot all bumrap kip kay give someone elce a go god i like kip kay but theres not only him on the world god

[bonesboy367]

@shaunh88 i used to just watch kipkay on make but i acedentally clicked here and now i like it

[planetdarwin]

hint: fill the bottom tubes with sand to make it heavy and sturdy to reduce vibrations

[planetdarwin]

i made one of these but woke up in the middle of the night with it standing over me, glowing red eyes.

[eekcage]

going to bodge one out of my cnc mill. wonder what type of CAM software you can use. I guess you can just mill in negative. lol ardweeno's are naff for kids

[pjerky123]

You are gay, kipkay is the best. The fact that you are gay is proven on 3 minute and 30 seconds. Gay Gay Gay Gay Gay Gay

[Lokivoid]

For future reference you dont need a thermistor or IR temp sensor. Just monitor the the heating element's ohm it will change based on its current temp. Theres a number of formula's for calculateing Temperature coefficient and Thermal conductivity.

[jamesdaniel222]

Thermistors have a wide range of sensitivity. they are silicone resistors with selectivity at room to +200deg C and higher. many materials have 5-10 deg c. since the range of temp selectivity does not cover the wide range of temp in this case use a 80 cent thermistor! temp regulation is the most important variable in 3d printing. not to mention some components used will break down and release poisonous gas if temp goes near 250 deg c! - like cyanide hydroxide if there is a nylon spacer!

[WildoTheRubberFist]

stick a router on it with a good bit and you got your self a mill...

[joesmoe71]

I'm going to build one and have it start automatically cranking out Terminators!

[walter0bz]

we'll be invaded by self-replicating 3D viruses!

[97273998]

@joesmoe71 haha!!!!

[97273998]

@joesmoe71 make it out of plastic so its easy to self replicate!

[lexxi0069]

is it possible to use the motor controller from a printer as a motor controller

[prankmakers95]

gay

[prankmakers95]

@IPHONEtouchDEVteam gay

[rumidom]

what hapened to this project?

[beornborg]

bre is cool

[chinchillasarecute88]

tHAT wAS coOL bUT WiErD!

[lewy0701]

he got a really thick eyes brow

[KLipneR]

this guy is such a tool.

[lilkillinmachine]

to turn on a PS i need to connect the green wire to any black wire?

[ALIVEWORKS]

Why not use a regular printer head to shoot down a mircon layer of photoreative resin. After the layer is completed, before the head returns for it's next pass you have a light source above the table expose this micro thin layer of photoreactive resin. Could take 10 seconds or more to cure it, but once it's cured, it's cured. The light cuts off & now the arm & printing head can make a new layer over the previous one.

[felony105]

I saw something like this once, I think it used UV light and cost ~$5000

[felony105]

But this one cost $500

[Duckyistrippin]

rapid prototyping machines can do all this, they exist already and blow this turd heap out the water. why bother? it would be easier to modify a hobby cnc laser machine into a rapid prototype machine than to build this junk pile.

[curtisbeef]

umm no your dumb real CNC = thousands you can make this for like 200 bucks less if you have alot of the stuff just laying around

[Duckyistrippin]

wow you can spend hundreds and have a machine that does nothing... wow. for the cost effectiveness of this you can just draw your parts in SW and have them proto'd for you... saving time and money. this is crap.

[curtisbeef]

Obviously you know nothing... having parts custom made cost hundreds of dollars in Tooling and other costs... also i don't see how it would not save time... what would you rather do draw up a part and print it out in a few min... or draw something up send it to a manufacture pay hundreds for tooling and possible get the part weeks later... go troll somewhere else

[Duckyistrippin]

you are obviously an idiot. do you have any idea what rapid prototyping is? its a vat of liquid polymer, a last traces out a 2d design one layer at a time, each pass of the laser hardens the material and keeps doing so until a 3d solid object is created. there is NO tooling cost. tooling is only needed for stamping/extrusions etc. this is mass production NOT proto'ing. this machine is a dirtball RP machine at its worst.

[penguinx42]

The point is this is make magazine and they like to ... well ... MAKE things. Making a cheap RP is more for the fun of building the project than having advanced RP functionality.

[samwab]

why are you criticizing the completely free alternative? google: "reprap poptech popcast"; 1st result is a 20 min video for you if your interested in not being ignorant.

[danxl5]

Thank you for this.

This man is a genious!

I shall buy his book.

Thank you again.

:D

[SOCOMSNIPER33]

IT IS BASICALLY A CNC

[lastasexual]

wilford brimley remix!!

[Coodude26]

I still don't get it... what the hell does it do!?!?!?!

[XxnicckkXx]

Its still in development. When it done it will beble to "print" out parts made of plastic. I think

[annoyinglylong]

In theory it should be able to print out even more complex things than just plastic... Freaky...

[hyperkris]

Yeh it should, it could just about print out almost anything, but it's in the primative stages.

[SOCOMSNIPER33]

YOUR WIFE WHEN YOU ARE AT WORK

[kremlinmoscowstaling]

great

[cyborgtroy]

Huh, this is... RepStrap, I thought they were building an actual RepRap... I'm perplexed.

[Jamieduk999]

lern how to do the following and make a pod cast about it.

make a conversion kit for a car so u can recharge from solar energy and make this easy :P taaaaaaaaah muchly

[cyborgtroy]

Too bad solar is still expensive :(

[OhNoIBarfed]

ur gay... bre is cool

[97273998]

@OhNoIBarfed XD

[stinkrat]

Hey that the whole acrylic board thing. You can make one out of thosee clear clipboards they sell at Wal*Mart. (and no I can't build this thing either.)

[Lobster1000]

´Can you use it like a cnc??

[shortcut007]

hey cool gizmo's :P but humm how many people can actually build that thing hehe 5- 6 people ? that listen to your show!? :P Don't get me wrong i like your show its interesting but i just wish you'd stick to stuff thats actually feasible in a weekend! :)

One fan : shortcut ,Canada,Quebec :)

[roidroid]

>5-6 people that listen to your show

video added: 14 days ago

current views: 19,766

[shortcut007]

nvm me i log on late sometimes :P i know alot of people listen to this show,i like it too! :)

i loved the gps and the pcb board videos :P!

it just came out wrong :/ i meant you got to be kinda advanced in electronics for this one and its weekend projects that thing looks long to make!then again like i said ,its all good!

i gave it 5 stars i usualy do! :)

[Clockworkforest]

I would have appreciated the definition of "repstrap" at the beginning of the clip.

[denilsonsa]

It would have been better if a quick overview of that hardware was shown. I mean, after everything together, what it was supposed to do, and how. Because, right now, this second part is just a bunch of pieces mounted together.

[hobojanglesJ]

Download the PDF.

[freelight57]

Um, great project, but either I am sliding out of Makezine's demographic or they are because these past few projects have had no practical or enjoyable applications for me.

I'd love to see a project on building your own walking retro robot. Reminiscent of the battery powered and LED flashing robots of the 80's.

[therealspacejunkie]

Different folks, different strokes. I am only disappointed that others are beating me to it - I am also trying to build a repstrap - although I want to get it to eventually handle the electronics too... This kind of project (and most others I suppose) is exactly what I am subscribed to makezine for.

[freelight57]

I find that fascinating. Maybe I'm looking for more of a Makezine Jr. Although, just being aware of the other advanced projects out there in Makezine makes for an entertaining read.

[hellstudios]

by self replicating does it mean it can have babies? 0.o ALL HAIL THE SEX ROBOT

[talledu]

Love your work but for the love of God get a wireless Lavalier microphone. Your audio sucks and is distracting.

[coolnerd92]

yea but hey u got 2 admite its relly cool w/ wut they can make lol

[pcz1]

Loose the on screen advertisement that's now

appearing at the bottom of your video. You

got the Ad on the left anyways. UGGGH!!

Arrrrrrrrrrrrrrrgggggg. I think I'm taking Make magazine off my Cristmas wish list.

[NGinuity]

Hey, that isn't a Make thing, that's a Youtube thing.

[sethmoyer]

that is on all youtube stuph, (google's doing, no doubt) and is extremely stupid, but it's no excuse to wimp out on SCIENCE!!!

[DOOMCame]

this could be a future mass production machine, awsome, im going to make one of these and use it to produce parts for everything around the house (my parents will thank me later for borrowing that money and never paying it back to them)

[gaimboi91]

wow a self replicating robot...almost.

[helivestubes]

I love this project but can you tell me why Im having dreams about Gov swartzinegger! lol

Keep it comin'!

[unicornhustler]

amazing eyebrows.

[jnbjabnk]

What is the actualy name of the robot the first part is Reprap and the seccond the Repstrap???

[sidekick3iskool]

who is actually gonna make this using instructions from this video?

[wmacorlando]

nobody - you need to download the pdf

[nicksuxs]

i feel bad for him

[RobertGoulet298]

i feel bad for you

[tetranoob]

I would love to know Make's opinions on thehouseholdhacker.

[jtriffo]

i imagine it wouldnt be very nice...

[afftonpimp]

bre are you going to "give" us the software???

[jtriffo]

its open source, so yes, it will be free, and open to change.

[BaronZombie]

The RepStrap Robot hurts my brain.

[OperationDanceDance]

Awesome movie Bre! I wonder what movies you will have in a year! Keep up the good work

[Peepo12]

those words are big!!!!!!!!!!!!!!!!

[cranie4]

Bre rules but I think I need to actually see what this and things like it actually DO before I watch these videos with anything more than mild boredom.

[clementckw]

YEA! i was waiting for the end to c what the thingy could actually do. its toooo complicated for me.

[pekepowah]

awesome proyect, we want more!

:)

[AndrewLife]

Can it print up a pocket-sized digital multi-track recorder?

[cvsps]

The RepStrap robot sounds like an awesome concept, but isn't anyone else a little leery about self-replicating robots? Anyway, I can't wait to see more of the RepStrap project.

[Cheesephilly]

The idea that robots will one day take over the world is ridiculous, WE program robots, and why would WE make one programmed to kill humans? Even if someone WANTED to the code would be amazingly difficult. I hate it when people say "OMG ROBOTS ARE GONNA TAKE OVER SOME DAY!!!!"

[ZullGostnu]

I am already the slave of robots and possessions. I work to pay for gas for the car, insurance for the car, license for the car, if it breaks, I fix it right away.  If I break, I just deal with it. I am a slave to the car.

[cvsps]

I understand that coding technology at this time is unable to truly duplicate human thought. But imagine a robot gaining sentience or self-awareness due to ambitious programmers. If we are ever capable of creating truly intelligent machines - we lose the control that we assume we had. I agree that the idea is far-fetched, but no one can guarantee that it will never happen. Apologies if the idea offends you.

[Idler81643]

well... if someday robots can have sophisticated human-like behaviors... i bet there will be reality robot show..

[desiredusername]

It's a tool capable of making all it's own parts. So is a metal lathe (or a full machine shop, anyway). It doesn't "self-replicate" like a virus does.

[mctylr]

But a traditional lathe is not computer controlled. The RepRap / RepStrap machines are semi-autonomous because the thermo-extrusion is controlled by PC software that holds the design pattern for the pieces that it makes.

While no one is making (serious) claims of "living machines," it is more automated compared to your machine shop example.

I tend to agree with you about the "self-replication" part being over dramatic. I think the philosophy of Fab@Home is more accurate (& less grandiose).

[rykkye]

It's extremely hard to make!

I feel a bit weird when he used the phrase "let's"

[lampstink5]

Cool

[desiredusername]

This is what it's all about, baby.

Why the saw blade?

[Coffeeeggsbacon]

i'll post a video response onto this one soon to show you the robot arm we've set up to draw people's portraits at my work.

[oppositronic]

i wonder if anyone will actually be able to make that

[kllktvtrmr]

Someone make a lasercutter out of this!

[farvision]

If it's going to replicate it has to replicate

all parts. In particular, you need to replicate

the electronics. Even making a wire would

be hard! So to get there you need to eliminate those things ... simplify simplify!

[dumtadum]

A replicating machine doesn't have to be able to make _all_ its own parts. For instance a human being needs several amino-acids that it cant make itself but have to get from other sources. This isnt a problem since its easily available by eating for instance meat. Copper wire isn't really a problem since it's easily available from any kind of broken electronics.

Making electronic boards is the aim of the next generation RepRap.

[farvision]

Ok, fair enough for a copper wire. But how about a transistor?

[dumtadum]

ok, you got me ;) Maybe an idea for v3.0?

[farvision]

I don't know. It seems that one would have a better chance do do it with molecules, but nobody has succeeded yet. The person who does will win a Nobel prize for sure!

[debrouillard123456]

When you break a bone, you go to a store to replace it, give me the adress of that store write. Just like we use food as building blocks of our body, this machine uses raw materials.

[Cssfiend]

id rather just buy a 3d printer :P

[Juicetin19]

Obviously you don't know that the whole concept of 3D printing is fairly new and that the 3D printers on the market right now cost $5,000 - $25,000.

[JXintheZ]

Insanely Cool!

[Starditions]

Looks interesting.

[infamousmfox]

This sounds so hard,but i think i can do it :)

hopefully.......
