LED Keyboard-Lamp

To save energy in my night sessions of programming i constructed a little lamp, which can be attached to the back of my Cherry keyboard without screws or glue.

So i must no more switching on my big light and i have no more reflexions on my monitor.

I have integrated a little switch.

For voltage i have opened my keyboard case und implemented an USB-connector for 5V voltage. But you can use any USB on your desk or from any computer.
I am using a warm white LED-stripe made for 5V. Please
