| Hi Gordon, When you mentioned about "doesn't have a ground in it", are you refering to the part the drives the LEDs, right ? If so, the explaination of the circuit is that when the output of the inverter that connected to a 100 ohm register goes low (...) (27 years ago, 22-Apr-97, to lugnet.robotics.handyboard)

| Help! I've purchased the Polaroid Sonar OEM kit, plugged them in in accordance to Kent's instructions and using his software, but if I plug in BINH through a 360 Ohm resistor or with no resisitor, all I get is 1 - 2". If I unplug it, I get (...) (27 years ago, 22-Apr-97, to lugnet.robotics.handyboard)

| Hi All, Had anyone actually built the Infared LED emitter circuit that is on the Rug Warrior? (i.e. pg 108 of Chapter 5 of the book "Mobile Robots" by Jones and Flynn). I've looked at it and I can't for the life of me figure out how it works. Before (...) (27 years ago, 22-Apr-97, to lugnet.robotics.handyboard)
