ticktronaut / gsmSwitch

This device can be controlled remotely by being called. The hardware is communicating with an old mobile phone by a serial cable using the AT command set. A compatible mobile phone has to be connected to it. Compatible phones (fi Siemens C55) and data cables can be purchased cheap on ebay. By calling the old mobile phone relais, or other hardware connected to this circuit can be accessed. The repository includes all eagle layout files and all libraries (gsm-switch hardware plus relais-board, level shifter for the serial cable). The source Code and some documentation of the project in the wiki will follow soon.
