My Biga Fridge


My Biga FridgeSubmitted by albacore on August 1, 2018 – 2:55pm.I came across this little 4l Peltier fridge at the car bootie and couldn’t resist it. I thought it would be ideal for making overnight bigas at 16C in the summer with a few mods.Of course, like many things car boot, it didn’t work! However it was an easy fix: the cooling fan for the hot-side heatsink wasn’t turning because there was a bit of plastic stuck in the blades.So, with the fridge working, time to add temperature control and cold air circulation. I fitted an NTC probe to feed back to my STC1000 style temperature controller and a 12v blower fan stuck to the roof of the fridge with double sided 3M tape to give air circulation.I haven’t used it in earnest yet, but my trial with a plastic tub of water looks promising – it was maintaining 16C accurately enough.┬áLance
