Hi magnetman, thanks for sharing, though will you share the circuit drawing and details.
I mean, if you will share them freely to a corporation, etc. then why not share them here, so people can benefit from your device.
peace love light

Hi magnetman, thank you for sharing.
The only part i have a question about, is the SCR.
I't looks like the only way the primary coils flyback can couple with the led bulbs, is through the SCR, triggered by the neon.
Just wondering what frequency the SCR is dumping the capacitor across the led bulb loads.
I assume it is fairly often to help boost the light output significantly more than typical.
This looks likes a boost converter, main difference being the capacitor dump function.
I have these 2.8 watt ikea gutted led bulbs, though i don't think they are 12 volt, because 8 volts dc brings them to their full rated input wattage, so i would need to get some 12 volt led bulbs also to test this design.
Are you using this same type of capacitor dump circuit with your 3.7 volt input version, because that would be easier for me to replicate based on parts i have right now.
Thanks for any help.

I used the very  same circuit for the 3.7  volt input version and the 12 volt input version.
My new DC watt meter only meters voltage from 6 volts to 100 volts. That's why you don't see it when I was experimenting with the 3.7 to 5 volt  setup.  The watt meter is present and correctly connected when I was experimenting with the 12 volt  wall wart power. That's to be sure voltage did not decay like battery voltage would do.   You can use this circuit with 24 volts also but be sure your 12 volt bulbs are series (2) connected together.  You will spend hours having fun with this HYBRID circuit   I never had it fail on me yet  Did get shocked when I was careless.  Once again be careful !      https://www.youtube.com/watch?v=o30z1iHDZa8

Thanks for the video. So the twisted coil is plastic coated wire. Fotos and Vids of the actual device help a lot.


Now, where to get such a SCR, are they expensive?
