If I do make a "MacMissile" - what is the smallest 68k logic board? I don't want the rocket to be too wide (and hopefully this small logic board will be cheap in case it explodes :-P) 2. How can I manage the voltage from a battery? 3. With the Serial Port, how (and with what hardware/software) can I send signals to open valves? I would like more info on the I/O Gadgets too ... > 2. use an I/O gadget, and a radio transmitter ( e.g. a mobile phone) in the > MacMissile(tm).
