    Surgically implanted obviously! Great idea. Now all I got to do is get all the locks in my life changed to be chip proximity activated.

    Kamikaze...

    The Voltage drop across R1 will be negligible once C1 has charged since the micropower PICs draw only a few uA. However I do have issue with Caps that size... they'll take forever to charge and the voltage rise-time at the Slave end will be so slow that the PIC will not initialise for the best part of a minute! Just work out the CR time constant!
