Just wondering, since these things run on 12v, has anyone tried running an S1 or S3 using a car battery?
Why? At best you'll get a few hours of a decent one and a battery will typically drop voltage as it discharges. Both of those don't really make them appropriate for mining with.
Maybe to run it of an old disel engine running on some cheap (disgarded/cooking/frying?) oil...
The idea originated as an off the cuff semi-technical discussion around could you, then very quickly turned to should you. Could, yes. Should, no. For the reasons dogie cited, of course.
Where's a functioning water mill with 12v generator attached to provide extremely cheap energy to run miners when you need one?
Answer: Not around here.
I would probably say couldn't for quite a period of the battery's discharge cycle. I'm not sure at exactly what voltage the S3 stops being able to hash but at something like 8, 9, 10V its not going to be happy at all.
