Joule Thief: Basic Wireless Joule Thief Remix
This is my version of the Basic Wireless JT. I was inspired to build the LED bank by Sohei Thoth, and I’ve been considering powering a JT with my wireless power system. So here’s…
Cool Joule – 0uA ? Brainteaser
Full spec, details and solution below. A variant of the Cool Joule circuit by TinManPower. See his channel for the original circuit and ongoing experiments. See Lidmotor’s channel for the circuit diagram and his…
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…
Electric OU: Supplement: MOSFET Input Capacitance Conducts AC
ERRATUM: A couple of times I say “Drain” when I should have said “Source”. The actual intent is clear, I hope, since the wires are color coded. This video refutes the assertion by Rosemary…
Earth Battery-Joule Thief Runs 48 Inch Tube (40 watts)
This is my earth battery running a 48″ (40 watt) florescent tube. It is not at full brightness but it is lit and lit pretty well. It is much brighter than it appears on…
Joule Thief Sounds
I am replicating a test I saw on the net where folks listened to their Joule thief circuits using an AM radio. Yes, this is still the same old AA battery as I used in all of my previous tests. Here I test a regular Joule Thief toroid circuit and the Fu…
Humidity Battery and a Tanked Joule Thief.ASF
This shows a battery that uses calcium cloride to draw moisture out of the air and help run a copper and magnesium battery. I also show a simple Joule Thief circuit that uses the…
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…
