LynxSteam's video: Lynx LJL with diode added

1. Super easy to install the Diode 1N4001, 4005, 4007 etc between base and emitter. I don't think there is an advantage to switching the diode. I would just put it in a n leave it. 2. The one transistor is sufficient, but yes I have experimented with two in parallel (place a 1 Ohm resistor across the parallel bases) 3. I have experimented with putting the layers in series, doesn't work as well. That's why I use a form of what I call "Tesla Parallel". Tesla used the parallel bifilar setup in pancake coils to great advantage. I see the same thing. Very clean high voltage spikes. I don't use three layers anymore. i found two layers works just as well. I measure 6" across a 9" length of 1.25" PVC and wind on 22 awg. Wrap with tape and then apply a second layer. I put a hooked loop on the second layer so its clear which layer is which. 4. "Runs Hot" really is slang for too many amps for the bulb and yes the transistor runs hot too. The diode prevents a negative bias on the base. Remember +/- is convention, but really represents electron hole flow. Electrons really run from negative to positive. 5. No, it is very difficult to measure the output voltage. It wouldn't be very meaningful. It is very spikey DC output. There is a slight AC component but it confuses multi-meters. It is better to measure DC amps in and multiply by volts. That gives you watts consumed. The LJL has achieved 112 lumens/watt which is better than running off grid power.
