Jose Julio made this awesome project and featured it on his blog with all the details.
Everything started when I built my 3D printer. First, the posibility to design and build my own parts and second, how could I hack the components of a 3D printer to make something different?
I have seen several interesting projects of robots that paint or manufacture PCBs, etc … but I was looking for something different…
My daughter loves the Air Hockey game and I love robotics so one day an idea born in my mind… can I construct…??… Mmmmm …. it seemed very complicated and with many unresolved questions (puck detection??, robot speed??), but that is also part of the fun…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!!
