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.
