This is a circuit made with the vinylcutter. The project involved designing the circuit, cutting it out of copper sticker, glueing it on paper, stuffing the electronic components and programming the micro controller to make the LEDs light up in a pattern. Step by step instructions how to do this will follow soon, here are some pictures of the process.
The design was based on the Charlieplexing array output board from the Fab Academy. These files provided a good basis to start from. I designed the circuit that contains an ATtiny 44 micro controller in Eagle.
