I recommend Sachgeschichten from "Sendung mit der Maus". It's a kids show that explanes the world and how stuff is made. The advantage here is that you can see what is happening while it's being explaned in simple vocabulary. Also it's really interesting.

I thought it's called bananenfalte (bananafold/wrinkle)

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...

Thanks! That might be good. I wonder if the Diode is bright enough, but I guess I have to test that.

True. Lots of them are watertight metal casing though. Thats why i was kinda hesitant to pick one.

 

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?

Habs mir letztens noch abfotografiert.
