Do you like 3D printing, mold making, industrial design, jewelry, and RGB LED’s? You’re in luck, then. I just finished this tutorial for Adafruit and think it’s well worth a look.
In this project, I attempted to make an Arduino powered device that was easy to use, easy to make, and self contained. Every 3d printed component can be done in a single build without support material. The ring has a battery, switch, and USB port. Once it’s together, all you need to charge or reprogram it is a USB Micro cable.
Long time no see, folks. I’ve got some great news for you. I’ve finally found a method for getting super complicated geometry locked inside of a seamless skin. It’s taken a lot of prototypes to get here, but I think the results are more than worth the effort. There are some wrinkles to iron out (which I’ll get to below) but all in all I think I’m incredibly close to rapid-fire casting working quadrupeds, ready to go in just a few short steps after popping the mold. In other good news, I’ll be dropping some files very soon which should get you your very own working quadruped using any FDM printer. All you need is a Makerbot or similar, a few hours, and some casting materials to have an exact duplicate of my most sophisticated robot to date.
This will be an update on the things I’ve learned molding quadrupeds over the last couple of months and some previews of the new robots I’ll be experimenting with in the next few weeks. To start, I’ve had the chance to run a gaggle of design experiments ranging from small changes to the particular silicone I’ve been casting, to more radical changes to how the whole plionics manufacturing process comes together.
Quadrupeds. I’ve been dreaming about quadrupeds. I’ve been hunting for challenges to test my methods and improve the engineering on the whole “print and cast a soft robot” thing (I really need to come up with a name for this… “Borgatronics?”). I started with tentacles because they were easy to design, easy to test, and symmetrical.
I am now the happy owner of a fully functional robotic tentacle. I’m pleased. After a few iterations, some hair pulling, and some welcome help from programmer, hacker, and generally pleasant person: TQ, the Trefoil Tentacle is now waving around in disconcerting glory. You can find a whole set of high res images of it here.
I just uploaded this little mechanical kitty to Thingiverse, and I think you should make a version for yourself. After a few trials with some cheap 1/4″ plywood, I ended up splurging on pressboard made specifically for laser cutting. The first cat I cut from the cheap ply ended up burning so much it was hard to get something functional out at the end. I blame the adhesive used to laminate the sheets. I think I might try and source some thin ply made with a natural wood glue. In the meantime, Laserbits makes some excellent laser specific stuff.
I really like candle making. Despite the mess, the cost of materials, the burns, and the constant fear of spilling hot wax over everything I hold dear, it’s completely worth it. If you remember, a long time ago I made a set of candles cast from impala horns. I’ve wanted to do more projects like this, especially as I ramp up to doing an absurd huge candle project based on much larger and more elaborate horns.
Early on in my days as a maker, I really struggled with documenting and publishing projects. Almost everything I make starts life as something I wanted to build, something I wanted the experience of playing with. Most often I build because building things is gratifying in and of itself, and the other aspects (recognition, money, internet fame) are ancillary. However, only ever being beholden to myself made for some pretty shoddy documentation. I have few if any photographs of my projects from college and my record of things before that is more or less nonexistent. Over time I’ve discovered that a huge motivating factor for me getting things well documented, taking time out to photograph a project in progress, and updating my records, is having other eyes on me. Having other people witness my work validates it, gives it context, and creates a network of fascinating relationships and interactions that help fuel the next piece.
I don’t think I need to emphasize how important documentation is. Objects have a nasty habit of being pretty solid and aren’t often seen hurtling through cables at the speed of information. I know, Thingiverse is neat, but if you truly want to convey the awesomeness of something to another human, it’s infinitely more likely that they’ll extrapolate the fact from a picture than take the time to print and assemble your design. So, if you want the world to feel the impact of your handmade steam powered arduino based self balancing stainless steel unicycle junkbot, you’re going to have to show them… by force if necessary.
The general idea is that I’d like people to be anonymous, wearing protection, projecting a captivating image, employing creative disruption, and in possession of crucial data whether protesting or no. I also believe in opening up the source as much as humanly possible/ethical/feasible on all of my projects.
