Bodkins Kick Starter 2 Transistor CFL circuit
This is Aromaz’s CFL circuit reduced to only 2 transistors. To get it into oscillation you need to “kick start” it with a jolt of electricity. This is Bodkins great idea and adapted by…

Joule Thief: Supplement: Photo Transistor NTE3037 Response Linearity Test
In order to determine the light output curves for JTs, one needs some kind of reliable and consistent detector system to measure the brightness level, and thus the light power output, of the JT’s…
1.2V simple ‘555 A-Like’ circuit
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…
Mosfet Transistor Slayer Exciter from Lidmotor
Copy of a video from youtube user: www.youtube.com user Lidmotor gave me permission to post it on my channel. Please go to his channel for more on this video. Many thanks.
Minnie Low-Voltage Cutoff Circuit Test
Developing and testing the Minnie LiPo Low Voltage Cutoff circuit. Schematic at the end 5:14. NOTE: The S Weir mods make the circuit work better. Use a 2n7000 mini-mosfet instead of the BC337 and…
Audio from a tiny Tesla tower – Walgreen AT
Speakers up !!! It’s dainty, it’s a pill bottle ‘Walgreen’ Tesla tower, running on 6V and producing audio ! Transistor used is a KN2222A, resistor 1K. Audio connections are straight from the earphone output…
TKLabs Replication: The "teslatronix" SSTC aka Slayer Exciter
An interesting effect is demonstrated near the end of the video, before the still shots. But is it really a Tesla coil? I have some problems with including this variant in with real Tesla…
Joule Thief Power Tube
Tinsel Koala (TK) at overunity.com tossed out an idea to have a JT circuit using a battery as the core. I thought this to be a brilliant idea. It probably still is…however, I have…
1 Solar cell powered Snake Egg Bedini
This is the one magnet Bedini (‘snake egg’) running on one small solar cell. The transistor in the Bedini circuit was changed to a small MPSA06 from a TIP3055. An oscilloscope is used to…
