Hey Gang,
what are these switches...
..the pic is the inside of a remote control. I must confess I've never fully understood these - are they capacitive/resistive etc - what's the deal..? if I want to make an external switch to trigger the contacts (ie us a picaxe to turn my laptop on/off) what would you do.? I can find the track and solder into it down the line a little then just short the to contacts together.. but I feel this is not the best course action.
I have a laptop (weather station) and I want to make a watchdog circuit for it.. because it locks up. Any ideas on the simplest way to connect something up to a USB port and be able to toggle that with software.. I can sense that state with the PICAXE and reboot if needed..
hmm...
