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…
Usually we think of turning on a MOSFET by raising its Gate voltage to 10 or 12 volts above the negative rail/source voltage. But what if the Gate is pinned to circuit ground or…
imageshack.us hehe back again, couldnt resist adding bulbs, now there is 12 watts of light in PARALLEL to the output, series connection is not as stable. This is very promising. it reads 0 amps…
I finally got around to the joule theif circuit and I’m glad I did! This will be fun. I really want to make an earth battery now as well but the ground is frozen…
Hi all this video is made to better understand the importance of the Kacher ‘s output grounding, and the huge electrostatic effect arroud the battery. So it seems that when the kacher is oscillating,…
THIS IS A 30 OHM COIL,28ga. AROUND A 4 INCH X .5 INCH HARDWARE STORE BOLT WITH A MAGNET AT ONE END HELD CLOSELY SO IT CAN SWING AWAY AND ATTRACT AS POWER IS…
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…
This video illustrates the effect of Function Generator Offset setting applied to the Gate on the behaviour of an IRFPG50 power MOSFET. IMPORTANT NOTICE: The scope probe waveform trace shown in this video is…
