wow!!! how unbelievably useful!!!!!!
Julian, Are you similar with the work of Forrest Mims in the 80's. He patented the reverse property of LED's, and when Bell Labs stole it, they went to war. Quite interesting. He wrote a monthly column in "Modern Electronics" and did a multi-part series on it.
You can try using a joule thief. Those only need 0.33 volts to operate. Current doesn't matter much as it is replaced by voltage. The current produced by the LED may not be enough to run the joule thief but I think it's worth testing.
Interesting, I was thinking about trying to light LED with another LED, but through a Joule Thief circuit
So will leaving my LED flashlight upright in the sun recharge it over a few days?
Nice experiment !

Do you think infrared leds will pull a lil bit more power from the sun? P:
If you shine a green laser at a red led you can light several other red leds with the output.
Hi I love your videos… And I have a question….Can you tell me what a C0301N chip is? And where can I find them?
I can find them in the internet
so you should be able to make a LED solar panel ? 100.000 LED's on a panel …..= solar panel question is would it be cheaper ? more reliable ? hmmm
i also did this a few months back and i found if you use a magnifying glass and focus the direct sunlight on a 30 watt led it will also light one of the small led's you have in your video.. not super bright but it does work .im wondering how much a joule thief would help this experiment? thanks for the video
I also have experimented with using LED's as a light detector. Ive used diffused colour LEDs to detect colours of course. And detecting UV via an UV LED connected straight through to an arduino analogue pin, It proved to be surprisingly sensitive.
I also noticed a strange fade like effect, My guess it is capacitance somewhere. But I thought it was because of internal ATMEL circuitry.
The blue one might be able to light a red one. Red LEDs actually need very little voltage and current. 1.7v at a few microamps would probably light up a red enough to see a little bit.
