A Burning CANDLE in Epoxy Resin

true dat

Here is mine....I think they were 2/US1$ and included a CR2032. The 'flicker' is not that candle-like, but they do flicker. Nothing in them but an LED, on-off switch and the battery.



If you look carefully, you can see the IC inside the LED


Here is a head on shot


These are as good as I could get with my lens.

just the thing for Dave's lab,  ... an idea for mail-bag.
or how about have a cheap fake iphone charger pcb explosion
with the flash and flames captured in resin, :popcorn:

Here is another resin project. Very impressive but a FAIL (watch to the end). I really did like the way he used the fiber optics with LED shells.

BTW: lest anyone think I am being critical of the effort, I am aware that if I attempted the project the video would finish with me in the ER.

Those flickering LEDs used in the little tealight candles never really impressed me much, they don't look candle-like at all. An actual candle doesn't really flicker much, it will waver a bit and may flicker in a breeze but the LEDs look quite exaggerated. I think a small microcontroller could do much better, especially with this candle that has two LEDs wired independently.

No, they don't impress me at all either (as you could probably tell from my original statement).

I like this guy's empirical approach https://cpldcpu.wordpress.com/2016/01/05/reverse-engineering-a-real-candle/
