Tiny Slayer Exciter mounted on a circuit board.ASF
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: Supplement: IRFPG50 N-Channel MOSFET Gate Threshold Voltage
Here I show the simple DC Gate Threshold Voltage test for the IRFPG50 n-channel MOSFET. It is pretty easy to see that a voltage fluctuating around 4 volts on the gate is sufficient to…
Electric OU: Tar Baby / NERD Circuit MOSFET Stress Test
The IRFPG50 is one tough transistor. Erratum: The duty cycle changed when I changed the range setting on the FG, and did not preserve the approx. 20 percent I had dialed in. Instead the…
Automatic solar charged Daftman LED Light
This the Daftman LED / charger light with an automatic solar charging circuit added. The addition is taken off a circuit posted at Talkingelectronics.com. The circuit posted there was for a ‘solar garden light’….
My 4evr Light
This is a glimpse at my “4evr Light”. It is a one led indoor light that runs all the time, doesn’t stop, and uses tiny polyacene capacitors instead of batteries. It runs on ambient…
Joule Thief LED Flashlight (Free Light)
This is a Joule Thief Flashlight. I simply modified a cheap 5 super bright LED flashlight that ran on 3 AA batteries by gutting it and using a simple Joule thief circuit which now…
Joule Thief Pirate Light
This is a simple light fixture made using a modified Fuji circuit Joule Thief and a disposable plastic food container. It lights up an 18″ tube pretty well and this is very easy to…
Running a pulse motor on infrared light.ASF
This shows my little light powered self-start pulse motor running on an infrared LED light source. The camera that I am using is able to show the light even though my eyes cannot detect…
uA Hartley transmitter circuit – Puddle Walker
See description: This type of oscillator has got to be one of the least power hungry on the planet. Lidmotor showed us his version, from a circuit found at Overunity.com. His circuit drew just…
