I recently acquired several Sharp GP2D12 IR distance sensors that I want to
attach to the RCX for use in the robotics course I'm teaching at Vassar
College. I found an RCX interface circuit for this sensor at
http://philohome.free.fr/sensors/gp2d12.htm
Before I go ahead and build it, I though I'd ask is anyone is aware of any
similar (simpler?) cicuits for hooking up one of these sensors to an RCX? The
GP2D12 asserts a voltage in proportion to the distance sensed, but draws more
current that the RCX normally supplies.
Ideally, is there a 'kit' I can but from somewhere with a PCB and parts that
Ican have my students solder together? (I could probbaly design a nice compact
PCB myself but I dont think I'll have time...) I've also seen various
recommendations about what diodes and voltage regulators are best to use. Has
anyone improved on Philo's design (no offense Phileppe - just checking :-)
Thanks,
- Gareth

| (...) Hi Gareth, i build a interface (mutiplexer) using one input for three (ore more with little changes) sharp GP2D12 and a 9V battery. (Actually Michael Gasperi builds it !!!! I only made some changes !!!!) Have a look at : (2 URLs) more general) (...) (23 years ago, 8-Oct-01, to lugnet.robotics.rcx)
