A project log for Raspberry Alarm Upgrade

That's not really challenging if you already have some electronic design skills. Simcom the company that sells the GSM module provides guidelines on their "Hardware design Guide". The software is really simple it's all python scripts on top of Linux.

I have a new PCB version currently being manufactured, I plan to publish all the design files as well as the software soon !
