$135 x 3 = way too much $$$.
Enter the iSpindle. Source code developed in Germany, i've been unable to find an easy build and setup configuration for this device, but im hoping it will be pretty easy.
Current parts list is below:
1x Wemos D1 mini
1x GY-521 Gyro & Acceleration Sensor (MPU-6050 on suitable breakout board)
1x DS18B20 Temperature Sensor
1x Square grid 3x4cm or printed circuit board
1x Resistors - 4k7 ohms - 220k ohms - 470 ohms
1x microswitches Or at the PCB Reed Wechsler
1x Lipo charger TP4056 (6 pin recommended)
In place of the 3x4cm PCB i've opted for the community created board which has the traces already laid out for this build, and they're dirt cheap ordered through pcbs.io

This board should make the whole build quite simple.
Another component is the "Sled" which fits all this stuff. Obviously this needs to be water tight, as it will be living in the fermentor. The general build is to 3d print the sled which will fit inside one of the XXL PET Geocaching tubes which is actually a plastic bottle preform.
Anyway, this is just to dump all these links and thoughts onto one page. I'll update as i continue the build. Im currently waiting on the PCB's to ship, and the PET Bottles to get here. I have everything else.
