Voltage regulator oscillator by Jonnydavro.ASF
This is Jonny Davro’s “Voltage Regulator Oscillator”. It is a simple oscillator using a 3.3v voltage regulator and a coil. I show it here running one of my low voltage pulse motors.

Bedini Leedskalnin – Lower Voltage Better Current
With each potentiometer tuned to each coil’s sweet spot and max voltage coming into the capacitor, I was unable to run the 18 volt drill (even with aid in starting). I then turned all…
Joule Thief Variant: Instructions, Detail
NOTE: I have the transistor backwards in this video! For some reason it still works with this particular transistor, but it won’t work backwards with 2n2222a. You must connect Cathode of LED to Emitter…
Extreme High Voltage: Fooling Around Blows the 15kV Supply
Ooops. Don’t try this at home, folks! I popped something in my 15kV supply. After a day of troubleshooting, I think I’ve isolated the fault to the oscillator board’s PWM chip, a common SG2524,…
Joule Thief: Supplement: NE-2 Voltage Threshhold Determination
Here I take one of the NE-2 bulbs and show how to find out what the voltage required to turn it on is. I used 2 x 220K resistors to limit the current and…
Joule Thief: JTEnhanced Current Input, Voltage Output Waveforms
It doesn’t seem right to call it a basic JT since the loopstick and capacitor make so much difference. So I’m calling the cap/loopstick version “JTEnhanced”. It is the basic circuit, using the 1K…
Joule Thief: LSGhostLight Voltage Rise from Added Capacitor
Does the LS “Crossover” circuit charge its own battery? Well, you can see the voltage going up when I hook up the 1uF bypass cap, and that’s definitely not electrolytic bounce. After reading gadgetmall’s…
Extreme High Voltage: Improved Vacuum Glow Discharge Demonstration
I installed a little ball valve and some better fittings in the vacuum line and vastly improved the tightness of the system. I can go for tens of minutes now with the pump off…
High Voltage Phenomenon – Gutted CFL Lighting 4 Foot Fluorescent
THE CFL BULB IS GUTTED. I thought this was Interesting. The CFL acting as a capacitor packs just a bit of a jolt…enough to light the 4 foot fluoro momentarily. I recommend that if…
Extreme High Voltage: TinselKoil 4 — MOT DC Tesla Coil w/ Blown Spark Gap Quenching
Here’s my “current” project: A small Tesla coil, with primary power from a Microwave Oven Transformer and a high-voltage Full Wave Bridge rectifier. I used a simple 2-element “blown” primary spark gap. In this…
