Creating an Air Hockey Robot with a 3D printer hack
Super cool project, all documented and open source!
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!!
