Heartbeats... We were using heartbeats in a couple of performances. We were not using microphones, instead we are using polar belts (the ones used in fitness studios). That means, you don't get the heart sound, only the beat information. We developed a little receiver for the polar belt transmission. The receiver forwards the heartbeat information to a analog transmitter, the ones used by musicians for guitar/vocals etc. You need that second transmission, because the polar belt itself just ranges less than a meter. That means you are actually wearing three pieces of equipment (polar belt, receiver, analog transmitter). At the moment i'm working on a much smaller digital system, but it won't be finished before mid october, because we are travelling right now. please feel free to write again if you need more information regards, frieder weiss palindrome On Sun, 9 Sep 2001 ShinyShiva@aol.com wrote: > Does anybody know a good way to get a live feed of a heartbeat?
