$40 temp control advice?

Zrab11 · Jan 15, 2012

I'm sure tons of you have seen this [ame=http://www.youtube.com/watch?v=7I-iwFLykxs]DIY Digital Temperature Controller - YouTube[/ame] but i searched the forum and couldn't find a recent thread on it..

Has anyone else tried to make it?
Is it really the best option for your money?

Most dual stage temp controllers are 100$ and this seem like a no brainer..
i can build 2 of these(1 for my fermentation chamber and 1 for my cellar) for the price of 1 controller?

I'm sorry if this has been talked about before..

Also what is the best heating element inside a chest freezer?
A light bulb? or a heating blanket? Or something else?

Thanks for any advice you can give me.

Aside from being in Celsius it is definitely the best option for your money.

Do a search for "eBay temp" and you should get plenty of hits in this forum.

I built mine last week. I already had a lot free parts laying around so just had to buy a power supply cord. $25 total investment.

I think this is one of the better solutions. https://www.homebrewtalk.com/f51/ebay-fish-tank-controller-build-using-wal-mart-parts-261506/

Instead of buying an actual extension cord I'd recommend just buying a power supply cord. I got a 6' cord from Menards for $4.

Also, I got my temp controller from this guy. Very fast shipping and a good price. eBay Temp Controller
