| | | | This is awesome. What are you using for the control circuit? Any chance you could use an RCX? KL (...) (23 years ago, 6-Dec-01, to lugnet.build, lugnet.general)

| | | | | (...) I think that it would be possible to use an RCX. I used four op amps in my circuit; the first amplifies the signal coming from the phototransistor, the second differentiates the signal, the third takes the difference of the proportional and (...)

| | | | | We tried using the Handyboard (which is faster than RCX) and it could not do it. I think the RCX is not fast enough for UNSATBLE control systems such as magnetic levitation, etc. A while back, I proposed the inverted pendulum problem as a challenge, (...)
