Cheap DIY fermentation chamber

[sbaclimber]

I finally got the heating pad wired up and thought I would share...
20€ for a used fridge
17€ analog heating / cooling thermostat with probe
11€ foil heater (~40-50°C)
1€ double pole switch
Ugly, but cheap.
(as you can see, I left the original thermostat attached to its probe and just taped it to the side of the fridge, should I ever want to "rebuild" the fridge)
Normally the foil heater just lies in the bottom of the chamber, I only raised it to fit in the photo.
The little red lever is the heating/cooling switch.

Thanks.
I suppose a light bulb in a can would have been cheaper, but the foil heater was just so easy and saves space.
Only drawback is, at 40-50°C it takes ~2 days for it to warm 25l. from 17° up to 23°...
