Fermentation Incubator Build

Got a Haier wine fridge off of Craigslist for $60. Score!
Fridge has a metal chilling plate along the back.
Drilled pilot holes and then mounted 118mm ceramic light fixtures, carefully avoiding drilling through the coolant channels.
Wired up with 16 gauge wire and crimp caps. Held in place with gorilla tape.
Drilled an exit hole for the wires. Had to widen this hole later to accommodate the fan and temp sensor wires.
Wires exiting the unit. Mounted a DIN rail.
Added aluminum foil tape to shield the wiring. Later added more to the shelf below the lowest bulb.
Added a power distribution fuse board for added safety.

Added a 92x92x25mm AC fan to distribute heat evenly.

Added a speed controller for the fan and cleaned up wiring.

Dual heating & cooling thermostat to control temps. Followed wiring diagram on the unit so that it can control both the heating lights and the fridge.

Sourced some additional shelves. Mounted temp sensor just above the second shelf from the bottom. Put halogen R7S 118mm T3 150W bulbs into the bottom two sockets. Ended up putting an LED bulb into the top socket since the additional heat was not needed.
It’s alive!
