I for one would look at your work if posted on some web site.

| (...) I'll see if I can get the circuits drawn up as jpegs and post them on my Brickshelf. Can't promise a schedule though :-) The IR Transceiver will be first, followed by a sensor port circuit. The other units are just possible future projects for (...) (20 years ago, 22-Dec-04, to lugnet.robotics)
