Another firefly themed project. I made this pin after the firefly jar. |
||||
Something I'd been wanting to do for a long time. Using the copper etch as a decorative element. I finaly had a chance to do that with this project. |

I use a coin cell battery to power the LED. The LED is controlled by an ATtiny85, which you can see just on the right edge. The metal pin acts as the switch. I cut the pin in half, and then soldered the two halves as part of the current path. |
