UnitCounter

This project is a system that I use in my waterski club.

Each customer has an RFID MIFARE card. On this card we write the name of the owner and we add credit. For me, a unit is around 1mn a bit more when the speed of the boat is over 50 km/h.

There are two boxes:

• One in the office to format, add, or remove units on the cards. It is based on a YUN and is using a web interface.

• The other one on the boat is removing units per seconds on the card when the boat runs and accelerates. On the screen, you see the customer name and the amount of mn still available on the card.

I need help to finish the box cleaning the code and make a nice PCB.
