Strange Stray Voltage Problem

Pretty neat. If you hold the antenna of a Motorola radio to a tube and key the mic it will light the tube too.

This an amazing hobby. I don't know anywhere else where you can pick up short courses in chemistry, biology, and electrical engineering.

 

 

I seemed to have solved the voltage problem, but I don't know exactly what I did that worked. I have finnally fixed the pH probe problem that seems to have been related to induced current. I just routed the cable a different way, and tried not to let it run parallel with any power cords. Things seem to be settling down.

That's good news. Glad you fixed it.

Great news.
