Update: Something happened I was hoping for, it started to 'sing' You know how a large ferrite ring can make a high pitched whining sound? well it did so with one type of wire up. I believe it was 5kHz that Steven Mark said his devices ran at, or similar around that frequency with each one. Yet, I don't know that anyone mentioned noise coming from any of them ?! A bit weird, if the things were putting out huge amperage and for there to be no audible ringing noise. Anyhow, this thing started to do that, lit the LED's brightly, but drew 130mA. It only did it after a lot of wires were shortened and the whole thing tidied up some. Next is to put the electrical tape on. 2nd update: Wrapped with electrical tape. Circuit held in place on a piece of black card spanning the diameter. Connections altered for 30mA draw. Now, it does something kind of cool, it's got a latching switch method for switching on, somehow. The batt can go in the holder and nothing happens, until I touch an added extra transistor Collector wire to any of the still exposed wires, then it fires up and stays running. The whole thing is nothing much, but has been fun to explore. Thanks to Szaxx, for the cork idea a few weeks back, before all this. I got interested in the whole story and am glad I built the thing for the experience of it.
