Hi, I'm hoping someone can help.
Im looking to get 1 led on at nightime only.
But it can only be 15mm deep. Battery as well. Its for a wooden fridge magnet.
Is it possible to do?

For simplicity, I think I would consider a "Joule Thief" design and single 1.2V rechargeable cell. The on/off control needs be nothing more than an LDR either directly shunting the base to ground or via an additional transistor used as a switch.

Hi guys I've had a read through and based on your ideas and thoughts I havemade the decision to double the thickness to 36mm. This should allow a much better battery choice.
I'm hoping this helps?
