Matthew Borgatti has built an air-powered, 3D-printed robot tentacle that waves in a friendly fashion and lends a helping hand. It is in no way erotic. Nuh-uh, not at all.
Print Your Own Robot: Part 6
So, with a very nice looking tentacle in hand, it was time to start experimenting with robotic air control. I believe I’ve found a system that works in a pretty simple and straightforward way. It still needs some work when it comes to the programming end, but I think the mechanics are well sorted. The idea is to pulse air into the tentacle using a solenoid valve, and have a constant bleed on the line so that flex will entirely be controlled by how long the valve stays on. It’s sort of a low frequency PWM. I’d like to get this working using a visual interface in Processing but, given how little I program, progress has been slow. I’ve got a thread on Adafruit with what I’ve come up with. In the meanwhile, you might like to check a rough video of the trefoil inflating.
Aliaksei Zholner’s Youtube account features various small, clever papercraft engines that he’s made over the years, but the latest one, measuring a mere 18 x 13 x 22 mm, is the daintiest, most lovely one yet, and well worth the long hiatus since Zholner’s previous outing.
Gulzada Ryskulova’s musical version of the Manas epic — a folkloric tale usually recited by Kyrgyz men — is nothing short of amazing, as is the tale itself, which was preserved through furtive oral tradition during the Soviet era, in which it was suppressed.

Unlike traditional lighters, the SaberLight features an electronic plasma beam that’s both rechargeable and butane-free. This sleek lighter is even approved by TSA, so you’ll never be stuck buying lighters you’ll just have to throw away partially used. For some people, like me, this is a pretty big game-changer. The SaberLight’s beam is actually both hotter and cleaner […]
