Wireless Door Unlock - TI Low Power Challenge

Our entry to the Texas Instruments Design MSP430 Ultra-Low Power Challenge (http://www.designmsp430.com).

Using the new eZ430-Chronos sport development watch, we created an electronic door unlock device. It communicates wirelessly to exchange a secret password (a sequence of taps on the watch's 3-axis accelerometer). Project detail description and source code available here: https://ziyan.info/2010/01/secure-wireless-door-lock/

Nice. I'd like to see a voice activation option on the watch.

Not very secure if everyone knows your password. Alternatively, using voice fingerprinting would seem like a bit much for this microcontroller to handle.

[Tsylord]

Sweet, but what if you forget your Watch and key?

[RITmdrc]

Then you don't get in your door? Duh?

[CoreoBroomstick]

But will it play Doom?

[beyond305]

[hahn0717]

@ericparrey also, the watch does not have a mic.

@WildSeven0079

you can use the door regular key and if you lose it too then get a biometric lock

[eldadmi]
