Gate current, gate voltage, linear operation region of the IRFPG50 mosfet. The gate current required to turn the mosfet on is shown to be extremely small and operating only during the turn-on and turn-off,…
As I was putting things away from my last video I made a chance discovery that the SEC can run on very few parts and light multiple fluorescent bulbs. It is running now at…
This shows Penny No. 2 running off energy gathered from a strip of aluminum foil placed underneath a tablecloth. A standard 110v table lamp is supplying the energy through and inductive type coupling when…
This is my USB device – Unexpected Solar Bedini ! Tinkering away this afternoon on something completely unrelated, I decided to see if a Bedini wheel would show any signs of life from solar…
This is a modified version of Jeanna’s Joule Thief FL driver circuit using a big 31/4″ toroid coil. The circuit is running on one AA 1.5 volt battery. A modified 10 watt CFL bulb…
Make your own. Use a strong neodymium magnet and a wooden or alluminium rail. Find 5 steel balls and it works.
NOTE: at the end of the video I say “nine times” but I should have said “Three times as much energy.” Sorry about the confusion, I’ve got volts on my brain. This is a…
What does the Current Viewing Resistor “shunt” actually measure in the Part 4 circuit and in the Donovan Martin – Rosemary Ainslie circuit? Does it measure current through the load? Through the Drain-Source loop…
Up is OFF. That is, when the gate turns ON the mosfet turns ON too, and the DRAIN voltage goes to the negative rail. When the gate turns OFF the mosfet turns OFF too,…
Please be sure to watch Parts 1, 2, and 3 first. Here I’ve taken out the light bulb (a low resistance non-linear load) and put 10 ohms of wirewound power resistors in its place….
