| >> 2. Constant wrist strap monitors are ridiculously expensive. No they're value priced!!! Does anyone have a layout/BOM to build their own monitors? | Dave F<< | Hi Dave! | BOY! You said it 'bout them things being expensive!! I found a web site that has some instructions of how to build a charge detector that's really sensitive...you can change the sensitivity by adding capacitors to it from what I read. | Anyways, this is a start and if I find anything else I'll post it here on the page. If you find out anything you post it too, okay? I'd like to build my own too if I can find out how to do do it... | -Steve Gregory- Steve: Here is a supplier's spec for a continuous monitor. It seems quite elaborate, but the idea of using operator impedance to ground to tune a Wien Bridge Oscillator is on track. Dave F http://www.pins.co.uk/afg/wristmon.htm
