I took a standard loopstick 1-10 mHy variable inductor and wound a “primary” on top of the loopstick’s original coils. I used this arrangement as the inductor in my JTBasic testbed, with the 2n2222a…
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…
This shows a Joule Thief inductor coil made out of just plastic coated steel twist tie wire. There is no ferrite toroid core used to make the inductor in this video but one could…
A 10 mH inductor pulled from an old TV chassis is the core of this JT. It looked to me like it had 300 or so turns on it of #30 or so. I…
The Altoid is shown driving a single LED load. This LED is shown being lit up in either orientation, depending on whether it is “shorted” by a 2.2 micrhoHenry inductor. Accompanying waveforms are shown…
Hi all This my first replication of the Rosemary Ainslie circuit as per described on her last paper. I ordered some of those IRFPE 40 mosfet because they are high voltage and low rds(on),…
Here I illustrate the basic procedure for determining an unknown inductance value. A known capacitor of high quality is selected, and the inductor and cap are connected together in parallel. A Function Generator set…
Hi all I am in an extra activated period because the evolution of the system permit to go fast, and each time with something new . I am amazed of all those new things…
This is a replication of the “Daftman’s” one AA battery LED light circuit. It was posted at the “Teep” forum and shows another way besides the ‘Joule Thief ‘ circuit to boost voltage high…
The Perepiteia Generator employs High Voltage coils to counteract the effects of Lenz’s Law in an electric generator while supplying power to a load, (otherwise called REGENERATIVE BRAKING scenario in an electric vehicle). This…
