Led flashlight driver circuit and sound circuit

It has a super smooth mirror looking finish where the two halves meet. It's performance is much better than my previous cores. It works better than any of the other ones I have tested. Have a great rest of the weekend everybody. Check you e-mail when you get a chance, I am curious about the voltage on the cap. I just rewatched them and gave them thumbs up because the videos were great and I notice that they had a really high ratio of thumbs down for some reason. Copper foils videos showing the low voltage with the third coil effect are really cool. This tells me that I can I can probably build the needed capacitance into the coil itself.

I often have to add them after removing the clip leads and miniaturisation of the circuit. I have actually found that the capacitor and diode are not always necessary. Of course I could be wrong but my working presupposition for years has been to avoid them at all cost. Personally I have never thought of a resistor as a good thing in a circuit like this. His explanation of the circuit reminded of Lidmotor's claim that this is essentially a tank am really enjoying your videos showing the many oddities with this circuit. Here is the schematic that I see as illustrating the heart of the SJR L circuit: Anyway I really enjoyed seeing the thought he but into helping other folks get the circuit going. It is my experience that the diode and capacitor can be removed completely. I think that maybe he thinks that the diode has to be there and that it has to be leaky. What do you all think of CoolJoule's latest video?

I also added this video showing how to wind the SJR coil: The previous one had the winding ratio flipped. Have decided to term it The Phoenix variant. I then tested it with an AM radio to pick up the oscillations and sure enough it trundles along fine when the LEDs are off, yet somewhere along the line manages to relight the LEDs. However, on removing the resistor, it still does it !Д¬hanging the capacitor value slows or speeds up the frequency of the circuit, but also changes the off time of the LEDs before they come on again. With having added a 1meg resistor in parallel with the usual small non electrolytic capacitor, I presumed it was that and I do say as much in the short video below. A few seconds later, the extinguished LEDs came back on and ran onward at a low intensity for a couple of minutes ! It didn't seem to work, would just show a really bright light and then switch off.Д«ut it hadn't. I wound a 150:400 of 40AWG on a small ferrite core. Which, I might say, definitely includes the next oddity ! Some unexpected runnings feature all over the place with the SJR L 4. With the version where 2 coils were stuck end to end, the distance between them decides the intensity of the LEDs and run time of the circuit.
