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?
Good news! Any thing can be dismantled if you are determined. Flashlights aren’t too complicated either. So yeah, any flashlight should work, and just start ripping it apart
True. Lots of them are watertight metal casing though. Thats why i was kinda hesitant to pick one.
For this use, definitely stay away from Maglites or other camping or survival type of flashlights. The cheap children’s flashlights usually have plastic housings that should be easy to open, and you can always put rechargeable batteries in them
Thanks! That might be good. I wonder if the Diode is bright enough, but I guess I have to test that.
I had the bright idea
Haha, I enjoyed that. Although you’re pursuing using parts from a flashlight, I wish to point out that LEDs are now fairly straightforward to put together into a full lighting solution. Generally, it would be an LED module, an optic, and the driver circuit. Maybe a heatsink too. Ok, maybe this is somewhat complicated lol
I’m not affiliated with that supplier, but I’ve bought from them before to build a custom headlight for a bicycle.
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…
