I have received and built the in circuit version of the flex foil programmer and now have it working. There are a number of issues that I still want to improve on. The programmer consists of an AVR ISP programmer sitting on top of my own USB CDC library called Gecko. I described this in…

Flex Circuit

As I experiment with the idea of flexible paper circuits I decided to try out a flex circuit material from http://www.conductiveinkjet.com/.The flexible circuit is available in 28cm wide sheets and the length determines the cost. The material costs ~$75/meter. To test out this material I designed a number of test circuits that could be printed…

With April arriving birthdays abound so I decided to personalize my cards using copper foil circuits. The concept was simple; have a card with coloured balloons and a gift. Each balloon would be backlit with colour LEDs while the gift itself would be a Tiny44 circuit running Arduino code. The RGB LEDs on the Tiny44…

Laser cut side lit LEDs

As part of my research into paper circuits I have been exploring the possibility of mounting LEDs on edge in a piece of matte board. This mounting geometry allows you to create a stained glass effect where cut-outs in the matte board are washed with colour from the side firing LEDs. To test the ideas…

Paper Tiny44 Arduino

March 3, 2013
By

This is my first look into the possibility of creating a simple computer circuit built of paper and copper foil. The design actually supports a complete Arduino sketch environment and costs less than $2 to build. So lets get started. Capturing the design I began by drawing my circuit using Eagle. Eagle is a circuit…
