I’d like to build a small light that i can use to cast a shadow to a wall.
It needs a single led that’s really small and bright and that can be recharged. Also I want to put it in a special casing.
However I don’t really know how to build one myself. So I had the I bright idea to take apart a flashlight that is rechargeable, but I’m not sure which one can be dismantled.
Do you have any idea what flashlight I could use or what parts I would need?
I already tried to calculate the right resistance for a 5 w Led, but that’s beyond me. Especially when I want to recharge the batteries.
I looked into Torch replacement bulbs. They seem to be simple enough…
