I finally bought a Beagle Bone Black and the first thing that struck me was that I needed a home for the board. I decided to make a laser cut plastic package so I designed the parts in Inkscape. Early…

Mini Maker Faire Ottawa
As part of the Ottawa mini-Maker Faire I decided to present a workshop on building paper cars. The project was complex and my initial days presentation was quite honestly a bit of a disaster and we had fun. I learned…
Paper Car
As I develop my small thin film processor I am often asked “What can I do with it?” The answer is a bit difficult since it is a general purpose micro-controller with Arduino like capabilities; “What can’t you do with…
Flex Foil Programmer results
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…
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…
Birthday Cards
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…
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…
Paper Tiny44 Arduino
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.…
Design Process ( don’t be afraid!)
Design is an art form and it takes many years to become good at it. I have summarized some of my thoughts on what works for me. These are tips that may even help you so don’t be afraid of…
LPC1347 Hardware Part 2
The minimum hardware to build the development board is shown here. The reset circuit is very important to the design because it allows you to either reset the processor or start the boot loader using a single button. A brief…
