Title: Anyone still Running A1 miners?
Post by: Theebard on November 22, 2015, 10:23:44 PM
A1 miners must be the most numerous around and I was wondering if anyone was still running there's even though they are a little high on the watts/gh side of things.

I have a couple of technobit  Hex miners still running as they are very reliable.

coincraft A1
they are made by a company that went bankrupt. 1th/s   1000W  28nm asic chip
you are better off with an S5.

Everything is always a question of electricity price.  ;)

I got a pair of Dragons going, mostly for heat in the apartment and office. They're close to breakeven and fairly quiet for 1KW. Rather have a half dozen S3 but you know, beggars can't be choosers.

I got my hex's for free so there only running at an electric loss but its winter so they help with the heating and something to do.

I wouldn't mind an s3 but the noise and electric costs might annoyed me. I manage to hide these hex miners in the PC milk crate :)

S3 is one of the quietest miners ever, and run about 30% better W/GH at stock than most A1 machines. Mine's throwing fits or it'd be in the laundry room right now spitting out toast.

I do have another A1 board on the museum shelf, I forget the numbers exactly and never turned it on. Little 5-chip thing.

+1 here, daughter's new space heater.  Also wish I hadn't sold my S3's...

I never had more than the one, unfortunately. They rolled out about the time I stopped being able to sink funds into buying new miners. I bought that one from Minersource last fall, mostly as impetus to get bobsag's attention so I could remind him about a bunch of gear I was owed.

I have several Bitmine Coincraft Desk V2's.  They are mining away at 1Th+

S3's do make good heaters.  I turned on 12 of them around my house over the weekend I can say they are nice and quiet and the house is comfortable even with the houses main heaters off.

I am using 2THs Dragon miner at 0.67V@1.2THs with around 0.6W/GHs. I replaced all fans with quiet Sunon Vapo bearing fans. It is very quiet and efficient miner.

I ran a Dragon 1T and later a Dragon 1.5T.   I eventually sold them off to lower priced electricity people.  They were tanks for the most part, besides PSU's on some of LKETC some crapped out.

I did not think I would ever sell my 1.5T it was like high 40 pounds is i remember right.  But I actually sold it and was able to ship for decent just was a little slower mail due to weight. 

Both were great miners for me.  I'm hoping Innsilicone has some A3's someday so we can see a next gen of them.
