I’ve been making a DIY watch using the MSP430 and a cheap display. It’s quite basic right now, but I’m planning on making the firmware better. It uses a surface mount MSP430 value line.
I’ve done some work on getting a Telit GSM module inside a watch also, but this one here is just a basic version. I had a voucher for a purchase at Shapeways that ran out this month, so I’ve ordered the case from them. That’ll allow me to compare quality differences of my Makerbot and the Shapeways commercial printers.
