You're one of the very few who has used that 1N4001 reverse voltage protection diode and you are very wise to do that. You can see why it's absolutely necessary. Remove it and replace it with two white or blue LEDs in series, connected in the same direction with their cathodes towards the base,...

Put a 10 or 22 uF capacitor across the LED. This will filter out the pulses and give you straight DC, and you should get the same result as if you had connected the flashing LED across a 3 or 4V battery. Without the capacitor, the pulses keep resetting the flasher inside the LED, so it never or...

"Music" is so bad I had to click the mute button. It would be helpful if you showed the battery current. In my opinion, most of the power transistors have too low current gain to give good performance in a Joule Thief. There are a few exceptions, one is the KSC2334. Series LEDs don't light up...

Yes, shunting the base bias to negative is not the most efficient way to turn off the JT. I do it several ways in my recent blog. You may have never thought that a red LED could turn off the JT. It's at rustybolt dot info and click on the link to my blog.

This circuit depends on the breakdown of the junction, like a zener diode, which is why it requires 12V. A true Esaki or tunnel diode requires a fraction of 1V and must have a diode with a junction especially made for the electrons to tunnel through it. Also, transistors w...

That's how the capacitor in my Supercharged JT works: it pumps up the circuit to a higher speed. That's why I call it supercharged. Instead of running at under 100kHz, it runs at over 200kHz. I've noticed that in some JTs, the cap causes it to jump into a mode where it's bright...

You're very innovative. But the LED light requires 2 or 3 watts to be as bright as on the AC line. And a single AA cell is just too low power to do that. It needs more batteries. I think I'd start with 8 AA cells and use one of the circuits that Xee2 (xee2vids) has here on YT for a LED...

Bifilar wound means that both windings have the same number of turns. If the primary winding has such a high voltage at 12V supply, then the feedback winding has the same voltage since it's the same number of turns. This is Really Bad. The feedback winding should be 10 or 12 turns, about 1/4 t...

I was disappointed to see you use the clip leads, when you had a soldering iron right next to the circuit. Clip lead 'spaghetti' just adds confusion in a picture or video. It would have been a lot easier to follow without the spaghetti.
Thanks for the instructional video. You're confusing efficiency with power consumption. The efficiency is the power output divided by the power input. You didn't do any calculation of that value. Also, the C458 and other transistors you showed are all Japanese with the collector in the center....
