Title: 12V piezo mister capacitive touch work around
Post by: phaseform on November 30, 2018, 10:52:39 am

I have a 12v car mister which is operated by a capacitive touch switch. I want to over ride this so it runs when powered always.
I haven't worked out the schematic to achieve this.. yet.
I'd much rather reverse engineer it and bodge a solution than try control it with a micro-controller...
Power cycle is:
1. power on: Red LED
2. blue LED, mister on
3. Blue/red LED, mister low power

looks like a little square of aluminium foil can trigger the sensor when grounded, so I'll use a micro controller to trigger it once powered.
