This is Kubikop’s ‘Joule Thief’ charging light circuit that I replicated. Here I show what the signal from the transistor looks like on an oscilloscope. This pulse is what is doing the work of…
Just fooling around. Schematic for the Neon unit is at http://www.overunity.com/6123/jule-thief/dlattach/attach/128708/ Schematic for the Clothespin (AcmeFixer) unit is the top diagram at http://www.overunity.com/13884/acme-fixers-highly-efficient-joule-thief-help-needed/dlattach/attach/128423/ As always with JT type circuits, if it doesn’t work at…
I made a “BristleBot” today and let em lose on the little boxed ‘joule thief’. Fun to watch. It was a draw and nobody got hurt. The “Thief” didn’t even blink.
Here’s an interesting effect I discovered just now. Don’t think your JTs are inactive just because the light goes out! Something may still be happening. Oscillations may start and stop without lighting the LED,…
This joule thief works much better when the ferrite core is shorted with a wire – a magnet or a capacitor. I adjust the trim capacitor for the best resonance. The magnet must be…
This is look at the Lasersaber Joule Ringer with an oscilloscope. The circuit I am using for this video has a .22uf capaqcitor in place of the bifilar coil and a 1meg ohm pot…
In this video I show the Joule Ringer output run back into the source capacitor through an AV plug. I also show a seperate Joule Thief circuit with a three transistor Darlington arrangement that…
This is a replication of Jonnydavro’s “Reverse Joule Thief”. It is an LED oscillator that will run at under 100 millivolts. I show it here with a microwave oven transformer but the circuit will…
This is a demonstration of the Link DSO 2102m Digital Sampling Oscilloscope, a PC-based 2 channel scope from 1997 era. The scope uses the ThinkPad 600e’s parallel port for communication and control and puts…
