Has anyone designed a power switch that works like a tablet switch.
For example if you push the switch it powers on the Propeller and if you hold the switch for five seconds it powers itself off.
I have not seen any project like this and would like to build one. I thought of using a couple of MOS Fet switches to do the work.
The Propeller could also start a watch dog timer and if there is no activity it could power it's self off.
