What would you say if I told you that I could make a Joule Thief without a transistor or other electronic parts, just a single mechanical part? Would you believe me? I have seem this method used many times in old radios and old equipment made before transistors were born. It’s not magic! You may

Quantsuff sent me a link to a short video of a toroid being wound using the cheating method. The toroid is broken in half, the turns are wound on and the two halves glued back together. Quite some time ago I participated in a discussion about doing this or a similar method and I’m not

Last year I experimented with the exciter that I saw on a Youtube video. It’s a simple circuit, and does some eery things, like light up a nearby CFL without any connection. The picture shows the schematic and how simple it is to implement.
Peter sent me a picture of his Bedini motor, with its colorful coil (see the attached picture). He says it draws 30 milliamps at 9V when running at maximum speed. There seems to be a large following of this Bedini SSG device, especially among the Free Energy advocates. It is called Bedini SSG, for Simplified

I’ve taken apart many disk drives, CD drives and floppy drives. The magnets are awesome! Another fun part is the motor. In the case of floppies and CDs, the head stepper motor is small, relatively powerful for its size, and can be used as a generator to drive a red LED connected directly to it

I found this website that has some interesting info, including what to use for EM absorbing material. He says to use magnetic recording tape.
I was looking at This model train web page about using solid state relays. He gives a few examples of what he calls “home made” solid state relays – I would call them discrete SSRs because they are made from separate components. There are a few things that I would like to add. He pointed
