Joule Thief. Amazing Hand Heat Energy. 0,1 volt part 3
A Peltier element delivers a small voltage up to 2 volts, when it is cooled on one side and heated on the other. Heat from my hand gives only 0.1 to 0.2 volts. I…

Radiant Oscillator Circuit / Don Smith Part 7 A: One Minute Run Time WITH Circuit 1 Farad Capacitor
2x 2n3055 npn bipolar transistors 2x ignition coils with no resistors -Test leads for connections -at least one 12vDC 3 watt led bulb -analog ammeter 0-5 amp (or 0-1Amp would work:) -12 volt battery…
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.
? – Flashing Oscillator
See Description underneath: I made a Dr. Stiffler type L3 coil last night, for use with the trigger coil circuit shown yesterday. All was going fine at 3V and 4.5V. Then, I placed 1…
Earthquake Powered Oscillator
The past 48 hours have seen 3 earthquakes in the local area. The epicenters of them have been about 50 miles West of us. 4.0, 4.7 and a 5.6 (Oklahoma’s largest ever). What that…
Extreme High Voltage: ZVS Royer Oscillator Driving Flyback Transformer, Jacob’s Ladder
The Flyback transformer is driven by a dedicated Royer oscillator Zero Voltage Switching configuration. I used 2 x IRFP260n mosfets, but I also tried IRFP460 which work but get warmer in operation. A few…
The Workings Of The SG Oscillator
In this video I’m showing again after one hour the two batteries, the one battery was pretty much charged the other was dead, in the beginning video they start out close to being the…
Joule Thief: JTBasic Powers the Ring Oscillator
The 5-mosfet Ring Oscillator is powered by the JTBasic on less than one volt input. I usually use a 9V battery to run the LED Ring Oscillator !!
Cement battery running a Hartley Oscillator Transmitter.ASF
This shows one of my cement batteries running a Hartley Oscillator AM transmitter. This oscillator circuit operates on extremely low power and can transmit a few feet. The circuit diagram shown here was posted…
1.2V Retro Chip Oscillator
Using an old microchip, it’s possible to build a simple low voltage oscillator. In this case, i’m using an LM339N, a Quad Comparator. Looking at the datasheet, quite often an equivalent circuit diagram will…
