I've just finish my first prototype. It was made with Autodesk's 123circuits. I ordered 3 boards and will arrive sometime in the next months. The tests with the Protoboard was successfull. I will post more details as soon as it arrives.
It will be my first SMD circuit, I have never used solder flow. Any tips apreciated!
In the meanwhile I have to continue the development of the android application and since I'm using a Attiny85 instead of an Arduino Uno I'll have to make the arduino code smaller without give up the security part.
