My DRSSTC is working at low voltage now, but I do not want to crank up the 
voltage without making some measurements. Here is a picture of my setup 
<http://www.hot-streamer-dot-com/chunkyboy86/spoolthing.jpg>www.hot-streamer-dot-com/chunkyboy86/spoolthing.jpg. 
The magnetic field from the primary is freakin' out the scope when the 
supply voltage is only 20 volts!

The noise on the scope doesn't change when I change the voltage dial 
thingy. The probes aren't long enough to move the scope, but when I turn 
the scope on its side, it gets better. The way it is now, I can attach some 
probes to the scope without noise, but when I touch the scope ground to the 
micro's ground, I get more noise!

Is there any way to make good measurements with the 60khz magnetic field, 
or do I just have to hope it doesn't blow up?
