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…
LPC1347 USB Library Part 1
In preparation for the new LPC1347 board I have compiled the USB code into a library file that can be included into a project to provide access to printf. The library includes access to the USB CDC, UART and standard…
Pogo Pins revisited
The last discussion about pogo pins was my first excursion into there use. The result was a purpose built programmer board to burn the capacitive touch switch firmware. I am less than thrilled with the complexity of assembling a test…
