Pat:381970 – coil run + metal blocks
Looking at Nikola Tesla’s US Patent 381,1970 today. The coil was wound as 36 winds per segment x4 segments. I wanted to check that the 30 gauge wire was not shorting. So, built up…

Following my video the other day for the soil powered flashing pumpkin, sMartcreations2010 enhanced with a circuit that can light 2x LED’s from a small power source. I replicated his design, but used a…
Introduction to the Nitinol heat engine as the Thermobile toy engine. This concept was killed by the oil industry in the 1980s as it was cheaper than coal- , gas- or nuclear- power plants….
Another conversion of a Hotwheels car. This time, with headlights and tail lights. The SMD LED’s are salvaged from old cellphones. All LED’s are connected in series. The headlights are on a separate circuit…
After the last video with the serendipitous wiring error, I decided to make an easily configured testbed and try some variations. Interesting….. I tried the generic 2n3904 type, reversed and correct, the metal-can 2n2222a…
Coils are not yet in resonance, but getting excellent results. Wanted to show the before picture… Experimenting with different combinations of capacitors & wiring arrangements. Primary is at the moment 100 winds of 12…
I’ll give all the specs, wiring diagram, and explanation of my ideas next vid 🙂 She’s a beast! I just got the first coil on it and wanted to show. More to come soon…the…
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…
I would like to start by saying that a couple of my resistors get hot with the wheel turning and no load on the charge terminals. In this video I start by showing the…
I installed a little ball valve and some better fittings in the vacuum line and vastly improved the tightness of the system. I can go for tens of minutes now with the pump off…
