Driverless LED experiments.

As requested, the addition of a smoothing capacitor to the driverless LED, plus a dielectric test on it's substrate.

I would imagine it would keep the voltage climb down but the whole array would then draw more power, so I suspect you'd get the same over-heating and down-regulation from the chips as a result of them passing higher current at the peaks of the sine wave as the cap would charge along with the LED's. Would minimize the flicker... I don't know how easy it would be to get to those tracks with all that silicone on there if you didn't know where to scrape in the first place.

great video. ordered some similar chips myself now. wouldn't it improve the power factor to put the capacitor in parallel to the string of LEDs?
