noodleFeet : Animating the Noodle

June 30, 2015spetku1 Comment

I’ve spent the last week learning After Effects. For someone who uses Illustrator on a daily basis, this feels a lot like discovering the magic hat from Fantasia. Among other things, AE allows you to turn a vector based 2D image into a fully rigged character for animation… and it’s even easier to do than you’d think. I had the idea a while ago to make a series of videos about Noodle and his adventures to Mars… The original plan was that they would be stop-motion shorts, made with a tiny 3D printed version of noodle as the puppet. There is no better terrain to fake as the surface of Mars than our very own desert outskirts… but alas, it is HOT out these days. Even if I could handle the relentless sun (which I can’t because I am WHITE), the PLA that the tiny noodle is made out of cannot. So much for the stop-motion thing. For scale (his eyes…

jellyBot : Rolley (the second prototype)

December 2, 2014spetku0 Comments

Ok, so the proof of concept I worked on back in October looked awesome, but it couldn’t really move on its own… and there were a couple of reasons why: I had mounted standard servos on the drive shaft instead of the continuous rotation type. I found out you need more than a breadth of 180 degrees to make a rack and pinion move far enough to do anything useful! Also, my drive shaft needed some roller bearings to tension the rack down onto the pinion in order to stop all the slippage. Since both of these things involve the mount of the motors specifically, I took the time to completely redesign that whole part to be more solid in general… after all, it is the very core of the robot- therefore the most important part! Tighter tolerances = happy jelly. So what I ended up making was a set of brackets that both…

Robot Army : From Tupperware to 3D Printing

February 27, 2014spetku6 Comments

When I moved back home from art school in Chicago, one of the biggest drags was no longer having access to the beefy machine shop that was down the street from my apartment. I went from playing with a room-sized lathe and mill to having little more than a $20 soldering iron and dremel at my disposal. It seemed my metal-cutting days were going to end as soon as they started… well enough, this didn’t stop me from making the things I wanted to. I just had to use plastic now instead. Luckily for me, plastic was in abundance at my parent’s house. My mom hordes take-out containers and tupperware, so I had a bottomless stash to carve up. Still pursuing my vision of creating the field of robotic flowers, I was trying to refine the design of my ‘steam’ into something a bit more controllable. At some point I…

SYN Shop Podcast Pilot

May 6, 2013spetku1 Comment

Last weekend my friend and collaborator Mark Koch and I were asked by our wonderful PR team at SYN Shop to have our delta robot making ‘rivalry’ featured in the pilot episode of the hackerspace’s podcast. Needless to say we were excited to help out and talk a little bit about our precious bots whom we’ve been building over the past five or so months. We each had goals to achieve before the episode was shot last Sunday, but both Mark and I had some complications that kept us from preparing anything epic quite yet. With the team’s deadline set before first friday, they needed to get things underway so they took what we had (even though we whined a little). You see… I had a lot of motors scheduled to arrive earlier this week, which they did on time as expected… however I am an idiot and ordered the…

Delta Robot Completed : Jeden

April 4, 2013spetku5 Comments

My neon yellow filament came in the mail finally! So last Saturday I monopolized the 3D printer at SYN Shop and made six new florescent arms to replace the grey and nasty transparent ones on my delta prototype. I also recut the robot’s base using some 1/4 inch acrylic, complete with name, signature, and project title etched along the edges. With the prototype upgraded, Jeden is now the first official addition to Light Play… and he’s a looker : Having figured all that out… it’s time to do the next step: Make about a hundred more. Alas, I am here at the hackerspace hoarding the Replicator 2, this time during off hours so I don’t get the reputation of an equipment hog. So far I’ve printed another set of parts and assembled a second robot making use of some old donated servos. I’m testing it out now to see if…

3D Printed Delta Prototype : Jeden

March 28, 2013spetku4 Comments

The last working delta robot I created was completed last August, nearly six months ago. I didn’t have access to a metal shop, so I relied on my dremel to do all the work and because of this it was made entirely out of hangers and tupperware. I hacked a multitude of plastic household objects and to-go boxes into actual moving robots… which was how I had expected to create the whole army of such deltas. That is until I met everyone at the budding hackerspace last summer and learned that 3D printers are now desktop sized. I’ve come a long way since then. Now having figured out how to make 3D models of the parts I need, I’m printing my robots like a more civilized maker. I’ve also departed from relying on hobby parts for the joints due to my friend Mark’s ingenious idea to implement ball bearings into…
