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…

Joule Thief: Variations… Alternate Toroid, Reversed Transistor Comparisons
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…
Small Transistor CFL table candle
This is a car ignition coil driven modified CFL light. The circuit is only two very small transistors. The circuit self oscillates by feeding back a pulse signal gathered by a thin wire that…
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…

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…
