I have an STC 1000+ unit that I used as a prototype for this project. This is the 2 probe version to monitor brew and fridge temperature, with settings to help reduce temperature overshoot. It has been wired up to light up a blue LED when the unit is cooling and red when heating.
It needs to be put into a project box and power points attached as outlined in the build thread.
I will flash it with 6 fermentation profiles of your choice.
Here is a user manual.

Asking $20.
Note: In the 1st 2 photos it has been powered via 5V DC and these wires are not attached anymore and the unit is sent as it looks like in the 3rd picture
