After several months of hard work ;) I hereby present an update on my home-made machine.
New features:
- construction is now stable, has rubber bands so it won't damage the floor
- significantly less vibrations
- added ball feed tube, now it won't accidentally tear off an arm
- electronic adjustment of rotation speed of each wheel (in a closed loop, PID controllers, opto-couplers and slot discs)
- electronic adjustment of vertical angle
- can be controlled with switches and buttons
- can be controlled remotely (currently with cellphone over bluetooth)
