New Pin Design

After two days of learning how to use Eagle CAD properly, I managed to get the program to do my bidding and produce the board layout for the new pin design I had in mind.

The new design features:

- Small size: 1.6mm in diameter, about the size of a 5p coin
- Flatter: It uses all surface-mounted components, so it should be only a few mm thick
- Two LEDs, controllable through a single DS2406 addressable switch which also provides 1kbit of memory
- Better efficiency as the LEDs have much lower power consumption than the standard 3mm ones we were using before.

The LEDs (blue!) arrived today from Farnell, but it will be at least another week before the PCBs arrive and maybe even longer for the switches to arrive from Dallas/Maxim.
