Mini Tesla Coil Light —at sea.ASF
This is the “Mini Tesla Coil Light” in a practical use on a sailboat at sea. I took this little light along on a sailboat trip to Catalina Island and it worked very well….
Bedini Earth Light—-replication.ASF
This is a partial replication of John Bedini’s “Earth Light”. It is an LED light that uses a simple one transistor circuit. The circuit design uses two chokes (inductors) instead of the standard bifilar…
24/7 ambient light osc + Rock Tester
A couple of ideas based on the no battery rock testing oscillator of the last video. First is shown a 24/7 ‘Forever Light’. It’s a similar idea to devices that Lidmotor has recently shown,…
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…
Tiny Slayer Exciter mounted on a circuit board.ASF
This is a tiny Slayer Exciter mounted on a circuit board. I show it here lighting up a 4 watt fluorescent tube as well as a neon bulb and three LEDs. The circuit is…
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…
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…
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…
