I want to build an outside bitcoin mining box that will have a roof and vents for Antminer s7, but will condensation be a problem? what about in the winter will it be too cold for it? I live in Canada. In the summer would it be too hot? Rain won't be the issue I will come up with a pretty good box design. What if it shuts down for what ever reason will it be okay?
Hi. I don't see any reason you can't run something that has fresh airflow from outside but just leaving the miners without cover would be a bad idea. You don't want them to suck in actual water. I'm in the Pacific Northwest and I've been running miners for 2 years in my 'garden shed'. I took out the wall on the exhaust side and put in screen. I leave the door slightly open and the space under the rake edge of the roof as well. It's in a sheltered placed so the wind can't blow in rain and snow.
If I were to build a minimal
BTC-Hive
tm it would be: roof-line->1 ft -> screen -> 2 ft -> intake of rack or shelf with miners -> exhaust of miners -> 1 ft -> screen -> 1 ft -> roof line.
I.e. you could put about 24 miners in a 6 ft x 6 ft (2m x 2m) configuration.
But I would certainly make sure the roof of whatever miner-house you build extends past each wall by at least a foot. If it's in the wind, then 2 ft on the prevailing wind side at least.
