Field, ball and gate, and player shirt

Getting first results about the IR commnication. We need to build all the IR transmitter with an 555 chip or similar since it's not reliable to generate the 38kHz wave with an Attiny or other µC

In our meeting we discussed the design of the goal. The ball has to trigger a switch to count the goal. After that event the ball have to get back to the field. To reduce human activities in this matter we decided to build the goal with a flap like mechanism which pushes back the ball to the field in a given time after the goal (maybe 5 to 10 seconds).
