My wife dropped her iPhone in the sink and she was trying to dry the phone out in a bag of rice. She was not happy with the results and said I should use my food dehydrator. The dehydrator got too hot so I setup the teensy I won in the teensy 2015HACKADAYPRIZE contest a few weeks ago.
I used components that will be used for my BBQ Smoker Temp Control since this was only going to used for one night.
Simple teensy connected to relay connected to dehydrator. 5 min on 15 min off for about 3 hours.
The iPhone was working after the 1 second dunk in water but the hardware buttons would not work and the volume display was constantly on covering the screen.
