A long time ago, someone had posted a link to a website that had information on how to make a sonar sensor pair for $10. Does anyone know where that site is? It must have been about 10-12 months ago. thanks! phil thehahns@nconnect.net (27 years ago, 26-Feb-98, to lugnet.robotics.handyboard)

Hello everyone, A few sonar questions (other than where to buy them): 1: The speed of sound has been widely quoted to be 0.9 ft/ms (274m/s), but my Physics text lists it as 343 m/s (at 20C/70F), which is about 1.13 ft/ms, or 25% faster. So why the (...) (27 years ago, 25-Feb-98, to lugnet.robotics.handyboard)
