Morse Blinky

Satellite dish free-form circuit sculpture that blinks an LED in Morse code

Similar projects worth following
First attempt at a free-form circuit sculpture. I had an ATtiny24a lying around and set up a simple circuit, powering the ATtiny from a 3V coin cell and driving an LED through one of the digital pins. The LED blinks out a message in Morse code, the firmware is stored in a Github repository. I used an Arduino Uno running the ArduinoISP sketch to program the ATtiny.
For the sculpture part I wanted something that looked like it was meant to transmit. I went with a satellite dish design using 22 gauge brass wire to build the structure. The dish form was built first and then I precariously soldered it to the base. Because the circuit was so simple I connected it in afterwards.
