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…
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…
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…
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…
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…
BoostPack Balancer Circuit Tested
I first saw this circuit on ebay from a seller called “cusdn”. I redrew the circuit for my needs and sourced the parts at Digikey. Parts, links and schematic here: http://laserhacker.com/ eBay schematic here:…
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…
