The pictures at (URL) the first we have seen, I believe, of the finished articles. One shot shows a good view of the IR control box with what looks like 5 buttons (L, R, Fwd, Back,. plus a trigger?) and a speed control. Looks like they might be (...)

After looking up some component data sheets, I've found myself wondering a few things: 1) The H8/3292 pin 42 connects to the D43256B pin 23. According to data sheets, this is A6 from the H8 and A11 on the RAM. Both data sheets show address numbering (...) (23 years ago, 15-Feb-02, to lugnet.robotics)

Stef (...) The IR LEDs are pulsed on and off at 30kHz - that's on top of the 2400bps serial signal. I had to remove that 30kHz signal. That's what the 100nF (on the base of the transistor) is for. The time-constant of the 100nF and the 470R has to (...) (23 years ago, 14-Feb-02, to lugnet.robotics)
