(...) Since 8" is the 'minimum' distance the board can see, I strongly suspect that your transducer isn't sufficiently damped. This will cause it to continue 'ringing' after the pulse is sent and when the receiver switches on, its still vibrating so (...) (28 years ago, 20-Mar-97, to lugnet.robotics.handyboard)

Hello everyone, My thinking (albeit limited), has been that simply driving an IR LED with ac (ie:40Khz) as opposed to static dc, is enough to discriminate it from other frequencies like 60 Hz. or whatever. Then, when the detector picks up sufficient (...) (28 years ago, 20-Mar-97, to lugnet.robotics.handyboard)

Hi, with all this talk of sonar, I thought I finally get to hooking mine up. All I get is 8". If I unplug it, I get 0". I'd swear I have it hooked up right. Someone sent out a mail earlier this week, and I had mine hooked up just like it said. I (...) (28 years ago, 20-Mar-97, to lugnet.robotics.handyboard)
