I designed all the PCBs using a program called 'Pcb' which is open source. You can download it for free from Sourceforge or Harry Eaton's PCB Homepage. It runs under X-Windows on *NIX (Unix/Linux/etc). It is a great program which I highly recommend.
The printed circuit boards were manufactured by Alberta Printed Circuits, www.apcircuits.com, in Canada. They had the lowest price I could find for our volume of boards we wanted. In order to reduce costs I combined all 4 circuit boards onto one rectangle. APCircuits encourages this (unlike many other manufacterers) and only charges the $40 setup fee once (otherwise it would be charged once for each board). We ordered 36 boards total. The plan was to make 34 of each circuit so we could have about 8 fail and still have enough for each of the 25 teams plus one for game control.
Notice how the Transmitter circuit uses up the extra space around the Bat Blinker.
We had a team of Game Control people help with building the boards. The experience level ranged from no-experience up to soldering expert. Many thanks to all who helped!
All the data needed to build the circuit boards is included in the file ju_circuits.tgz. It contains several files.
