Fresh from the tips line, [Pedro] sent in his GSM alarm. He combined a GSM phone, a motion sensor and BasicX24 controller board. If the detector trips during a set time period, the alarm sends SMS messages to the terminator, er whoever you want. He was kind enough to release the code, but I’d like to see this with a smaller micro-controller board to keep the cost/size down.
I don’t think it was meant to be alarm clock.. perhaps a typo.

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.

i was looking at a very similar idea for a car alarm.

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

You can use a smaller board like this.. http://www.wrighthobbies.net/catalog/product_info.php?cPath=21&products_id=30

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

So… not really an “alarm clock”. More like motion detector with text message alarm.
