More info below – Versions of TinMan’s recent Cool Joule SS SSG circuit. Original video here: http://www.youtube.com/watch?feature=player_embedded&v=2fvLwjvTA60 Tentative results, lots of tests and verifications to do. The first build trundles onward from yesterday when it was built, putting a few…
This is a test with a Tesla bifilar pancake coil (made à la Jiffycoil methode). The wiring is on a standard Joulethief circuit with a TIP 31C transistor for voltage up to 24 volts (probably more is possible but my…
this is a test on Garry Stanley motor set up. i first made 2 pairs of coils . One pair is with cw winding on the top coiul and ccw winding on the down coil. I noticed no difference as…
I was inspired to build a little magnet spinner by synchro1′s interesting work with a large powerful sphere magnet. I don’t have such a magnet, but I did have some little discs. So I mounted a disc magnet on an…
The mystery of the really long running has been solved, but i’m glad I asked about the observation and thank you for the kind responses…perhaps others would be stuck for an answer too were they to use a similar setup….
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 and the valve closed before the…
The JT Basic circuit is used with a 1n914 (or 1n4148) diode in place of the Base Resistor. Cathode towards transistor Base. The circuit is the Basic 2n2222 or 2n3904 JT, available everywhere. the inductor is a two-coil inductor on…
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 is switched by the mosfet drain-source…
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 gauge wire, L2 is going to…
I’m varying the input voltage to the PCB JT and monitoring the input current on the Tek 2213a scope and the oscillation frequency on the Philips PM6676 frequency counter. Power is supplied by the little HP 721a PSU and the…
