Hartley Flasher – Low power JT alternative
See description: Joule Thiefs are great circuits, but, it seems the Hartley oscillator might be a winner for flashing LED uses. Main idea is for low power requirements of micro aircraft….these can run in…

Here’s my build of a great little wireless power transmitter and receiver that was shown in a video by user MarkoBakula at www.youtube.com Please see his video and comments for the schematics and templates…
Hi all The user PASCUSER at OU proposed to us some time ago the technology of Richard Vialle.. Richard Vialle proposed to make an experiment , as to bend a copper tubing of exactly…
I’ll give all the specs, wiring diagram, and explanation of my ideas next vid 🙂 She’s a beast! I just got the first coil on it and wanted to show. More to come soon…the…
Here I continue to demonstrate the versatility of the simple Arduino pot-voltmeter system. NOTE: I get scrambled when I describe the mosfet pin hookup. The Load has no connection to the mosfet gate, it…
After the last video with the serendipitous wiring error, I decided to make an easily configured testbed and try some variations. Interesting….. I tried the generic 2n3904 type, reversed and correct, the metal-can 2n2222a…
The ClownSnake Skeptics Society has contacted me with a very critical message, saying that I didn’t measure the input power properly in the last video, and that while I might be able to fool…
The JT Basic circuit is used with a 1n914 (or 1n4148) diode in place of the Base Resistor. Cathode towards transistor Base. The circuit is the Basic 2n2222 or 2n3904 JT, available everywhere. the…
The mystery of the really long running has been solved, but i’m glad I asked about the observation and thank you for the kind responses…perhaps others would be stuck for an answer too were…
Another conversion of a Hotwheels car. This time, with headlights and tail lights. The SMD LED’s are salvaged from old cellphones. All LED’s are connected in series. The headlights are on a separate circuit…
