An N-channel mosfet is used to demonstrate turn-on from a small gate charge, and then the linear operation of a mosfet is demonstrated to show the difference between a SWITCH and a linear amplifier…
www.americanantigravity.com – We examine a space nuclear Radioisotope Thermoelectric Stirling (RTS) generator on display at the STAIF Conference. RTS generators are a new breed of space nuclear power supply that use radioactive decay to…
The Arduino is a flexible platform for controlling all kinds of devices from all kinds of input signals. Here I demonstrate the most basic Analog Input — a voltage from a potentiometer — and…
Once more for the LULZ. The common gate amplifier is evidently more mysterious than a pot of stone soup, but if one pays attention one may begin to become enlightened. This video is a…
This is FAIR USE of this video for the purposes of education and forensic investigation. This is an unedited copy of the demonstration that Ainslie freely distributed as a live “hangout”… but which she…
The same setup (IRFPG50 in linear conductance region, NTC thermistor monitoring bulb temperature, airflow sensor) is used to demonstrate that the mosfet’s capacitances can and do pass AC current between Gate and Source, and…
After the research and analytical work a new theory has been developed and now Jovan Marjanovic and academician Veljko Milkovic are presenting the theory which says that acting force against moving body will not only accelerate the mass…
This is a great, inexpensive kit from Elenco that I purchased from Amazon. It is very handy for tuning JT circuits. I made only two modifications. I added banana plugs to the front where…
This little gadget is primarily for Joule Thief research, where the relative brightness of an LED must be compared or monitored as conditions change. The TSL235A is a small sensor that converts light intensity…
When an N channel mosfet is configured to switch a high side low impedance load, the Drain voltage is HIGH when the mosfet is OFF, and when the mosfet is ON, the drain voltage…
