Hi there
I want something that is self-powered without any dangling cord. Small but controllable, able to press on/off, and I came up with this:

Components:
- IR LED
- Single core wires
- Screws and nuts
- 2 x cable lugs
- plastic washers
- 8-pin I socket
- Micro push button switch
- 2 x LR44 button batteries

I do not have an appropriate resistor so I am driving the IR LED directly from the batteries.
The reason for the 8-pin IC socket is to allow me to add a resistor later on and to change LED whenever it blows :-(
