Joule Thief: Making a Quick and Dirty PCB Joule Thief
Here I show how easy and quick it is to make a simple printed circuit board for your Joule Thief. Copper clad board, the resist pen, and Ferric Chloride etching solution are available at…

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…

This is my version of the Basic Wireless JT. I was inspired to build the LED bank by Sohei Thoth, and I’ve been considering powering a JT with my wireless power system. So here’s…
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,…
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…
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….
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…
A project i’ve wanted to try for a long time..could a working circuit for the lights from the Knight Rider KITT fit in a HotWheels car ? Yeah, kinda, at least in the slightly…
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…
