| I don't suppose you know what the formula is for calculating the value of the frequency ?. 1/(R4*C6) possibly ?. This equation gives 38396Hz (38.4KHz) which means that my 6.6nF caps give 39560Hz (39.6KHz) which is closer to 40KHz than the 6.8nF (...) (26 years ago, 12-Jul-00, to lugnet.robotics.handyboard)

| If you want to return to "base," all you need is a beacon of some sort. For example, you could use CdS cells (or anything that finds EM in the visible light/low IR range) and a lightbulb (or series of lightbulbs, like a strand of Christms tree (...)
