Jose Julio realized that the drive-train and parts in a Reprap printer could be repurposed, along with an Arduino-controlled vision-system to create a robot air-hockey opponent. He documented the build here, and the code is on Github.
Based on the idea of use standard RepRap 3D printer parts : NEMA17 stepper motors, drivers, Arduino Mega, RAMPS, belts , bearings, rods, printed pieces ... I started to develop the project. The main advantage of use these parts is that they are cheap and easily available. First I started with the construction of the air hockey table. I choose a medium size (my house is small, ;-)) I wanted something easily transportable but comfortable to play. The final dimensions are 100x60cm.
I Bought some wood boards and wood slats and began to mount the table. First I started to build and airless version but it really lacks the feeling so I decided to make a table with air. I tried different possibilities until I test a very simple combination with 2 old PC fans that works very well. I made the table holes (it seemed a hard work but it was not so hard) and I now I had a fully playable Air Hockey table! Time to enjoy it an play!!

SOG’s $60 Sync II “wearable belt buckle” multitool isn’t the only multitool/buckle on the market, but it does add a couple very sensible innovations, like a clip-on/clip-off base that lets you use your tool without taking off your belt, and a squared-off form factor (like a pair of folding travel sewing scissors) that adapts the […]
Stories matter: the recurring narrative of radical Islamic terror in America (a statistical outlier) makes it nearly impossible to avoid equating “terrorist” with “jihadi suicide bomber” — but the real domestic terror threat is white people, the Dominionists, ethno-nationalists, white separatists, white supremacists and sovereign citizens who target (or infiltrate) cops and blow up buildings. That’s what makes Brian Wood’s first Briggs Land collection so timely: a gripping story of far-right terror that is empathic but never sympathetic.
The campaign to raise $500K for the UN High Commission on Refugees started with author/comedian Sara Benincasa daring Neil Gaiman to do a dramatic reading of the Cheesecake Factory menu; Gaiman responded that if she raised the half-mil, he’d not only read the Cheesecake Factory’s (notoriously florid) menu, he’d follow up with a reading of […]

The Ticwatch 2 Active Smartwatch is a simpler take on an active wearable that raised over $2m dollars on Kickstarter and is currently offered in the Boing Boing Store.Somewhere in between the single-day battery life and platform-specificity of the Apple Watch and Android Wear devices, there exists the Ticwatch. Instead of trying to shoehorn another […]
