GG430 tipped us about MSP430s being used in the Axbo alarm clock. The Axbo is a sleep phase clock that wakes you up gently when you are most “awake” in your sleep. There are two parts to it – the base alarm clock and a band that transmits your movements to the base. A maximum of two bands can be used to connect to one base. Openbeacon has a sweet teardown of the device.
The base of the Axbo clock(above) features the MSP430F436 – 24Kb Flash and 1 Kb SRAM. It also features an LCD driver capable of running upto 160 segments.
The band consists of a MSP430F1101A with 1Kb flash and 128 bytes SRAM. It senses motion via two tip sensors(X and Y axis) and transmits them via a Nordic NRF2402 radio.
