1. So... not really an "alarm clock". More like motion detector with text message alarm.

2. You can do something like this with an AVR. See application note AVR323 for details. Not with a motion sensor but that shouldn't be the biggest problem.

4. I don't think it was meant to be alarm clock.. perhaps a typo.

5. Shame you can't automate MMS , you could use the cell phone's camera and not have false alarms. now that's useful!

6. you can automate mms and sms. which would be a better solution.

a $0.98 8 pin pic chip and a little bit of coding and this could be easily done for far cheaper.

Basic stuff here guys

7. smaller and cheaper... I managed to get sms control (both ways) using a pic (16f628) using fbus (not AT)

9. cheaper chips but usually more expensive to do development wise, although maybe in another 6 months the pic world will gets it's development stuff cheaper then the stamp
