Internal Bulb Circuits
A quick test of an idea, thought about for some time but not implemented. It struck me that a lot of circuits are around to light household bulbs with batteries, but the circuits themselves…

Two JT Circuits In Parallel Test Rig
This is a test rig to allow 2 HV JT circuits to be placed in parallel. I can operate 1 JT circuit from 1 AA battery or, tie two JT circuits together from the…
Arduino 9: Driving a Bipolar Transistor: 2n3055 As Light Dimmer
Another application of the simple, sensor driven voltmeter. The 2n3055 bipolar power transistor is used along with the Arduino’s pwm output to function as a sensor-controlled light dimmer. The photovoltaic cell is still useful…
Joule Thief: Variant with 2n3055 Flashes CFL
Dimly it flashes, less than 1.2 v input . Same circuit as before but with NE-2 removed and CFL wired in place. 13 watt 120 v unmodified CFL.
Don Smith Device Project Part 19 C: New Driver with L1 and L2 Tank Circuits Complete
Completed the Tank circuit for both L1 and L2, the values are not quite correct for L2, .03uf is what i need, but i accidentally used .3uf 😀 So it should get even sweeter…
pt7 THE Slayer Exciter, Toroidal Capacitance, 3 Coil Style, 48 Blinding Lights
http://slayerexciter.com/ I recently purchased the Slayer Exciter dual resonant kit that GBluer is selling, along with 3 sweet circuits and components except for the 48 LEDs. Here I’m rocking the TMT with a PNP…
Electric OU: Testing a Bedini North Pole Motor Coil
As described in the video I wound a coil for a Bedini North Pole Motor, and I used a mounted 2n3055 transistor from one of my JT circuit variants, in the Bedini circuit arrangement,…
Joule thief – RE-EMF Charger – by Rene
Charge Lead acid, non rechargables, rechargable battery’s. With this technique you can revive your dead battery’s. Super simple but very effective 🙂 Please build, test and let me know what you think ! And…
Ring The Bell Twice
So what do you think he meant now? He prescribed using a solid U made of soft iron. Should we listen to him? Haha…I was just considering a core for my new set of…
Axial inductor solar oscillator
Full info below: A poster on Lidmotor’s latest video, called Iluzyin1, spoke of using axial inductors on blocking oscillator circuits. The bright green resistors on 1990’s circuit boards weren’t bright green resistors, an education…
