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!!

I'm in the midst of couple of weeks' worth of lectures, public events and teaching, and you can catch me in Toronto (for Word on the Street, Seeding Utopias and Resisting Dystopias and 6 Degrees); Newry, ME (Maine Library Association) and Portland, ME (in conversation with James Patrick Kelly).
Octavia Butler (previously), the brilliant Afrofuturist, McArthur Genius Grant-winning science fiction writer, died far, far too soon, leaving behind a corpus of incredible, voraciously readable novels, and a community of writers who were inspired by her example.
EFF has just posted a job listing for a development director, seeking someone to "take charge of EFF's eleven-person Development Team in their efforts to raise over $13 million each year," starting late 2019 or early 2020.

When it comes to data analytics or deep learning, there’s one language behind the apps and algorithms that power the biggest companies of today: Python. The best part about this tool is that as versatile as it is, it’s actually fairly easy to learn. But mastery? For that, you need more than just a beginners’ […]
Your smartphone’s GPS is a modern necessity for some trips, but how do you use it safely? It’s been a problem ever since phones went mobile. A certain phone mount even shelled out the money for a commercial during the Big Game, so clearly there’s a market for the solution. Turns out there are a […]
