First ten done!

First ten detector boards have been built ready for testing.  Not quite the same as the first plan, as I've made the board square.

Chess Set

After a no show for my first Ebay purchase, another was ordered and arrived the very next day!
This set is not as good quality as the first, but will do to create the prototype.

The chessboard folds in half so this should help with getting the board under my pilar drill to create the 64 holds needed for the LED's

LCD

Got a serial LCD unit from an old Firewall I had. Attached it via a level shifter to the pi's serial port. Didn't have much luck with getting it work. I will also need to create my own LCD routines. I think a LCD connected to another MCP chip may be the way to go. Wiringpi should make the coding easy. One on order from eBay for the sum of £2.00 post free!

Still waiting for the chessboard :-(. Looks like first class post from Birmingham takes more than a week!

Stripboard

The strip board has arrived, just waiting for the chessboard.  Once I have the chessboard I can look at cutting the strip boas into the correct size for mounting the LED and reed switch.

Cell Idea

Added an idea for each chessboard space (cell) to build matrix, see the hardware page.  I will need to build 64 cells for the complete board, so this idea may change!  Using stripboard will lower the production cost, but will be more labour intensive :-)
