    I've built a schematic from the PCB, it looks like everything is accessible. Next step is to try and get a JTAG link up with the processor.

    This information will be very useful.

  • Opening the case

    Popping the case open reveals the spartan interior:

    Not much to mention here, we have a PIR sensor, a PIR dedicated chip, and a radio module.

    The PIR chip is an Elmos E931.96 IC with two signals: Interrupt/Serial Out and Serial In. 

    So far this looks extremely hackable. I could easily replace the module with my own header, plug this into an arduino or raspberry pi and call it a day. I don't think that's enough though, I want to see if I can break into the module.
