1.2V simple ‘555 A-Like’ circuit
Low voltage, low current possible solution for those without 555 timers in the spares box. The basic circuit is much like a Joule Thief, similar toroids, windings and transistor can be used. The Collector…

Minnie Low-Voltage Cutoff Circuit Test
Developing and testing the Minnie LiPo Low Voltage Cutoff circuit. Schematic at the end 5:14. NOTE: The S Weir mods make the circuit work better. Use a 2n7000 mini-mosfet instead of the BC337 and…
Electric OU: Grey Box Q-17 Circuit Heat Output vs DC Input Run 1
This is the first experimental run of the test series, more or less a shakedown run. I am testing the Lost Grey Box circuit published by Rosemary Ainslie in a set of photos last…
My 4evr Light
This is a glimpse at my “4evr Light”. It is a one led indoor light that runs all the time, doesn’t stop, and uses tiny polyacene capacitors instead of batteries. It runs on ambient…
Daftman’s 1 AA LED Light—-My replication
This is a replication of the “Daftman’s” one AA battery LED light circuit. It was posted at the “Teep” forum and shows another way besides the ‘Joule Thief ‘ circuit to boost voltage high…
Running a pulse motor on infrared light.ASF
This shows my little light powered self-start pulse motor running on an infrared LED light source. The camera that I am using is able to show the light even though my eyes cannot detect…
Joule Thief Pirate Light
This is a simple light fixture made using a modified Fuji circuit Joule Thief and a disposable plastic food container. It lights up an 18″ tube pretty well and this is very easy to…
Joule Thief LED Flashlight (Free Light)
This is a Joule Thief Flashlight. I simply modified a cheap 5 super bright LED flashlight that ran on 3 AA batteries by gutting it and using a simple Joule thief circuit which now…
Electric OU: The New Ainslie Circuit
Just for fun I put together the new Ainslie multiplemosfet circuit, using 2n7000 mini-mosfets. It oscillates just fine, batteries in or out….. because it’s running on power supplied by the function generator. It’s insensitive…
Electric OU: Supplement: The Ainslie Quantum COP17 555 Timer Circuit
As I first discovered in 2009, the Rosemary Ainslie Quantum Magazine article describing her claimed COP over 17 circuit includes a 555 timer schematic circuit that produces an INVERTED duty cycle from that claimed…
