Working on a new addition to the homebrewing setup. I want to be able to detect water/beer levels in the pot. This circuit will read multiple probes to detect which ones are in water and report the status back to the raspberry pi over the usb serial connection.
I started with a simple circuit I found online, then added my own twist. Had to relearn eagle cad, then sent the eagle project file to Oshpark to get some PCB's made.

Next step will be to get my 3D printer working so I can print the following enclosure that I drew up in Fusion 360.
