Hello my fellow flashaholics!
I am currently trying to make into reality a little idea I had regarding thermoelectric generators. (TEG)
As we all have experienced at one time or another, flashlights can get quite hot. After seeing what thermoelectric generators can do I have wanted to experiment by seeing if the heat produced from a flashlight can lessen the burden on the battery.
However, know knowledge with circuits is quite limited and I was wondering if you folks can suggest ways in which one can power a light source with two fluctuating power sources? I understand this project is not by any means the most practical but I am doing this strictly for novelty purposes.
I plan to use an XP-L HI LED as my light and one of the two power sources will most likely be an 18650. As for the TEG 90% of out there are 40mm by 40mm which I feel is a bit large for my application. A 20mm by 20mm would be an idea size. In addition to this they all ship from china and I do not think I can wait 2 months for shipping so if you know any good sellers please let me know!
Any electrical, science, circuitry, or shopping advice will be greatly appreciated!
