Earlier in the year I needed to build a control system with the capability to detect alcohol vapour, measure fluid temperature, sound audio alarms and trigger relays. I designed a circuit board for the Atmega 328 chip and soldered all the components on to produce the finished item. It took quite a while to to this, and, whilst testing circuits on a breadboard was ok, I could really have saved myself a lot of bother if I had had a PCB that could be adapted to my needs, rather than creating a whole new one from scratch. So, after the project had finished, I thought what would I have liked to have been able to buy to have produced that project and what would I like to have to produce future projects, without the time and expense of getting batches of custom made PCBs made for the specific purpose. This was when the idea of a flexible, hackable, multi-functional PCB came to mind.
