This is a tiny Slayer Exciter mounted on a circuit board. I show it here lighting up a 4 watt fluorescent tube as well as a neon bulb and three LEDs. The circuit is…
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…
Electric OU: Grey Box Q-17 Circuit Heat Output vs DC Input Run 1
This is the first experimental run of the test series, more or less a shakedown run. I am testing the Lost Grey Box circuit published by Rosemary Ainslie in a set of photos last…
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…
