Well I'm planning to make an oscillator with a 555 to feed the coils as the original circuit but backwards. The original circuit is not using a Sine wave but a square wave for feeding the input, then in the output the signal is a rounded one by the action of the coils, don't know if it's a perfect Sine wave. I hope next week I can measure it and may be I can upload some scopes so you can tell too. -- *Leonardo Marsaglia*. ------------------------------------------------------------------------------ Download BIRT iHub F-Type - The Free Enterprise-Grade BIRT Server from Actuate!
