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.

Jonny’s Voltage Regulator Oscillator– part 2.ASF
This is more work with Jonny Davro’s “Voltage Regulator Oscillator”. I show it here running a spinning magnet on a mirror.
Bedini Motor running on regulated low power
This is an electronically fired pulse motor. It is using a device called a ” step down adjustable switching regulator” that is 90% efficient to control the supply voltage . A small solar panel…
Table Candle II
This is my “Table Candle II”. It is a small battery powered flourescent light. What is different about it is that it uses a regular inverter circuit with an adjustable switching voltage regulator. This…
Bedini SSG capacitor motor running on indoor ambient light
Little Bedini motor and BIG solar panel running indoors with just ambient light and no batteries. Light energy is being controlled by a “step down adjustable voltage regulator” which allows energy to build up…
Pulse Motors: MileHigh OpAmp Comparator Driver Development #2
I’ve added a 0.1 uF bypass cap on the power input leads, and added the mosfet and a car brake light bulb for a test load. One thing I determined is that the op-amp…
Extreme High Voltage: 15kV Supply Repaired and in Good Health
The 15kV supply that I popped a couple days ago is now repaired. I first disconnected the HV section’s primary from the driver transistors, and powered it up by simply hooking the Interstate F43…
Joule Thief: NE2 JT Converted to Wireless Power
I took the 10mH , 4-neon JT and removed the aaa battery it was running on and replaced it with the Simple Wireless Receiver with DC output. As you can see the system works…
Joule Thief: Basic Wireless Mod 3: Smoking Receiver
I noticed at the end of the video that something in the receiver components was smoking…. I think it was just the voltage regulator getting warm, nothing to worry about, no components are damaged….
Joule Thief: Basic Wireless Mod 2
A bit of care with the antenna and bit more tuning capacitance and the performance is increased. 26 cm distance between antennas before the 5v regulator drops out.
