Try the following link for the Zener diode:
7V Zener Diode: KELVIN.com
NOT-SO-SMALL-PRINT: I have never tried the circuit below & I only know enough about electronics to be dangerous. You’ve been warned. Good luck, and let us know if it works.
Thanks a lot Earthman, dig the name by the way. I have a little experience, as I am currently working on a few of Tesla's projects, and have been zapped by a capacitor or two...lol owch that stuff hurts. Lesson learned. I'll try the circuit and let you know what I find. Thanks all!
