IMPORTANT NOTICE: This video fixes a problem with the Scope Probe in the last mosfet video that caused an inaccurate display of the Drain Trace waveform. The previous video concerning the effect of Offset…
Here I continue to demonstrate the versatility of the simple Arduino pot-voltmeter system. NOTE: I get scrambled when I describe the mosfet pin hookup. The Load has no connection to the mosfet gate, it…
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…
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…
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…
This little box has, inside it, some kind of circuitry that harvests WiFi energy out of the air and converts it into electricity. This has been done before, but the Airnergy is able to…
Using the nano-pulser with a MOSFET and MOSFET driver. Forum: www.overunity.com Incoming search terms:lm393
One of the many Akula circuits, under construction. Testing the “output” stage which consists of one of the six inverters in the 4069 and the mosfet it is driving. I’m using the FG to…
A simple circuit describing high-side switching using a random N-channel mosfet. Also showing that the gate needs only Charge to switch and if the Charge stays on the gate it keeps the mosfet ON….
I finally got my Slayer Exciter to run on a Mosfet transistor. The Mosfet is a Radio Shack IRF510 which isn’t supposed to work, but I got things just right and the magic light…
