Guilherme created what may be the most inexpensive iteration of Arduino yet -
This is a 100% functional version of the Arduino. We eliminate the PCB and use paper and cardboard as support and the result is.. the PAPERduino
This is the the first version of the layout design, next we will try more designs, and another materials. You just need to print the top and the bottom layout, and glue them to any kind of support you want. We hope that you start making your own boards. If you do, please share your photos with us, we would love to see them
Very cool – a wooden Arduino would be quite awesome as well! Check out Guilherme’s site for the printable design and parts list.
