Announcement: Bitmain launches AntMiner solution, 0.68 J/GH on chip

In January and February I had s1s that were roi positive too.

But now they are not because the difficulty has gone up too much.

My point is it mines less now because the difficulty is 16.8 b not 4.3 b was in March.   Its hard to pay more than $80 for a s1 now if it can only mine about .13 btc.   I would rather buy coins btc on Coinbase than overpay for a s1.

It will have a value as a heater starting in October. Which heater "almost" pays for itself plus reduces the gas bill?

Yes this was the good idea they had earlier. Or maybe some people can sneak into the office and use their electricity.

I just made a heater savings calculation
My house used 232 CCF of nat gas for ~$200 in january 2014
103100 btu/CCF
Antminer (almost all heat) at 190GH uses~400W=1364.85btu/h
1364.85X24x30.5 (average days in a mo)=999070 btu
hence, one antminer saves 9.69 CCF in heating/mo or $8.35mo, so 10 antminers (or equivalent kw) would save ~40% of the gas bill. Not bad.
even better if you pay higher nat gas price (i see that it is ~30% higher in new England)

The s1 only draw 370 watts instead of 1500 for regular space heater, and the fans are more powerful so would throw more heat around a larger space too.

Just mount the S1's in the HVAC ducts and your whole house benefits from the heat

They make Great Towel Warmers
 No more cold bathroom floors.
 Placed properly they can eliminate the frigid toilet seat as well

Does anyone know if there is a firm shipping date for S3 Batch 1? 

[jimmyoh]

Does anyone know if there is a firm shipping date for S3 Batch 1? 

I think that Bitmain said that they would start shipping Batch 1 orders around the 14th.

But I would not call that firm.  They start assembling boards, heatsinks, fans, covers tomorrow.

I should pay attention to it here, in Siberia... The winter is getting closer each day...

I'm pretty sure all of the $400 coupons expired on June 27th  

$1450?... I don't know if I'd trust a seller without any feedback yet. I can discount by $110 though now! New price is $1529.99. I also have a bunch of single batch #1 S3s for sale (and 2-packs), but I would recommend buying directly from Bitmain (minimum order of 2) if you have the bitcoin since they're cheaper than I can offer when accounting for Amazon fees.

Yeah, mine expired on the 27th too. Do you offer tech support or have a policy for DOA units?

I do offer support upon request, but I've been fortunate and very few people have needed any. Those who have needed help were mostly unfamiliar with networking. I've only had 1 customer claim to have a DOA unit and I refunded him in full upon returning it to me. I was able to get the unit running right away, so I'm guessing it was another networking issue
