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!!

A team of material scientists from Northwestern University figured out how to make hair dye in various shades of grey, all the way to a very, very black black, out of graphene sheets.
Steven Brust is a literary treasure and his longrunning Vlad Taltos series, now nearing its final volume, is a good example of where his strengths lie: hardboiled plotting, snappy dialog, weirdly realistic and plausible depictions of magic, and a sensitive eye for power relationships and their depiction, all of which are on display in his latest, outstanding novel, Good Guys, about the minimum-wage sorcerers who investigate magical crimes on behalf of a secret society.
