I made a card for a friend. I didn’t want to give just any old, boring card so I decided to add some pretty lights into it. This was the result:

Underneath the tracing paper (which diffuses the LEDs) is an ATTiny84 microcontroller, some 1206 LEDs and a whole lotta copper tape cut up into traces.

The kite has 4 LEDs which fade on and off using the ATTiny’s PWM channels.
The traces were drawn out with a pencil before putting on the copper tape.
