The perfect night-light, and a great way to learn how to solder.

The Joule Thief is a clever little circuit that can light a LED with a battery that is nearly dead. It does this with a pair of opposing magnetic fields. I like this circuit because it is simple to...

I've designed a printed circuit board to help make this easier to build for beginning Makers. I used open source KiCAD software to lay it out (a future Instructable?), and OSHPark to manufacture it. If you want to just wire one up without the board, check out Angelo's Instructable which uses essentially the same circuit.

If you want to learn a bit more about the principles that make this circuit work, check out this video: http://youtu.be/0GVLnyTdqkg

The kit contains:

1 - PCB, https://oshpark.com/shared_projects/rLeF8F88
2 - AA Battery Clip, Keystone Electronics #92
1 - Ferrite Tubular Bead, Digi-Key 240-2301-ND or similar
1 - SPDT slide switch, E-Switch EG1218
1 - 1K resistor 1/8 - 1/4 W
1 - PN2222 Resistor, Fairchild Semiconductor PN2222ATA
2 nanoseconds (about 24") of insulated wire. Two different colors are helpful.
1 - LED, 10mm white (or use your own)

Great Product

The Joule thief came on time. It was new-as advertised. I am very pleased with my order; and, I would definitely buy from this seller again.

Really enjoyed this little project

Wanted a little kit to demonstrate the joule thief circuit and this is perfect! Easy to assemble and compact; it makes the perfect little desk widget.

Great kit

I bought this kit as a beginning solderer, and it was very easy to understand and put together. The PCB is excellently made, and the 10mm LED is a good size and shape for making an LED lamp.

Great First Kit for Beginners

Used it as a first soldering kit for middle school students. They enjoyed the construction and the fact that it worked upon completion. They are now asking what the next project will be!
