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.
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.
“Have fun at home with my old rubber boots,” the creator writes. Avant-garde performance art or fetish video? You decide. One commenter’s rave review: “Nice boots. Rubber seems to be very soft.” (via r/DeepIntoYouTube)
Donato Sansone “Concatenation 2” film connects a series of acrobatic Olympic athletes’ jumps, spins, and dives into “a series of interconnected things or events,” which is the definition of “concatenation.” This delightfully disorienting video is a sequel to Sansone’s original “Concatenation” film here.

You may not realize it, but some of the biggest films in movie history have been edited using the same tools some of you use to cut your video of vacationing at Disney World. Giant movies from Oscar favorites The Social Network and Gone Girl to blockbusters like Avatar, Deadpool, and last year’s Terminator: Dark […]
Now that the initial furor and shortages have subsided, it’s probably not a bad time to start considering your long-term cleaning and disinfecting plans. Sure, that might seem anywhere from overly cautious to outright ridiculous, but the threat of COVID-19 appears poised to be present for a while and the need for quick travel clean-up […]
With more and more companies moving all their operations into the cloud, the need has never been greater for those with the skills to map exactly how an organization reconstitutes itself in that new environment. Network architects responsible for determining all the communication, storage, and infrastructure needs of an expansive organization are among the most […]
