Tinyish 1w usb flashlight
As we happen to have some of those powerbanks lying around I figured I could try and make a flashlight even though those banks do have some flashlight already.
- 1W (so they say) LED
- 27ohm resistor
- some perfboard
I did cut a bit too small piece of the board after trying it into a usb connector so next one needs to be a bit wider. It can also be a bit longer.
It is quite bright. Hard to tell from the photos.
