I disagree. Ebay is a reasonable way to judge a paypal-priced value for things, and for people who have no BTC and have no way to easily get BTC paying a 10%+ premium via ebay/paypal is not terrible.

and even if the equipment stops being profitable in 5 months with a $600/BTC, if prices jump to $1000 you can suddenly get another 2 months use and quite likely make a profit. You need to look at the value of the mining equipment both in terms of current market conditions as well as how the market may be in 6 months from now, or a year form now.

If BTC went up to $2000 during July, even the 7w/GH BFL equipment would start coming back online again and making small profits

OP is updated with the new cables photos and pricing.

The splitters look great and I personally will be using a pair of 24" leads with a splitter on each so that I can run 2 antminers per DPS800 PSU (using gigampz board). The non-tinned ends also make these a bit easier to work with since the tinned stuff was stiff and unable to twist together very easily.

you would not replace the chips - you would replace the two PCBs and keep the fan/frame/heatsink.

Its not viable until the S1 is worthless (another 2 months if you undervolt or have cheap power), but would save about $20 in raw materials ($7 fan, $13 aluminum), maybe $5 worth of assembly time, and about $40-60 on shipping. Overall it would be a savings for bitmain of about $60-80 and probably passed on to buyers as a $40-60 discount over an assembled S3.

Are these no longer shipping on the 25th as promised? I have had no recent email communication and no tracking info on an order i placed almost 2 weeks ago that should presumably be with a courier by now.

hop off your high horse - manufacturer threads are 100% fair game for [reasonable] criticisms and complints.

The SP-10 is a great (but noisy) machine. The SP-30 looks very promising and should be useful for at least 8-12 months minimum due to its class-leading efficiency. However, $5,000 is a little steep - particularly for a preorder - and I would not invest in one until it is shipping in under 2 weeks from payment.

Bitcoin is volatile right now. Within the next week both bitmain and asicminer producers (rockminer and btcgarden) will be in feirce competition and will be fighting to get thier respective 0.8w/gh and 1.1w/gh products down into the $1/GH range. Between then and the SP30 september batch it is likely that difficulty will almost double.

*as a side note - raskul is free to resell SP30 preorders at retail prices, but it should be obvious he is probably getting a 15% or better cut for bulk ordering like that. If you want to pay $5K for an SP30 buy it direct from spondoolies*

I am assuming that some of the increase is definitely Bitmain.

Asicminer and Bitmain both have chips and both have products that are on the cusp of shipping out. Its quite likely that they are doing all sorts of pre-mining and burn-in testing

Its now the 25th - will I get my shipping notification soon?

could be an issue with the higher voltage (12.4-12.8v) that often is produced by server supplies. Check the below image and try adding a wire to the gigampz board for  voltage sense - that should cause the PSU to correct the output back into the proper 11.9-12.2V range that perhaps the habernaro requires

still no news?

In most cases, the S1 will still operate at a profit for several weeks, and undervolting will add another month or two to that. No point upgrading it until the S1 boards are worthless, right?

IMo, 0.9-1.1 BTC is the fair price, considering that the miner will probably produce ~1.9BTC over its lifetime, minus ~$400 in power costs at $0.15/kwh.

a large part is variance. a few days of good luck after a few days of bad luck could cause huge jumps like this. If you flip a coin and get heads, tails, heads, heads, heads, tails, tails, tails, it does not mean that the physical properties of the coin changed during the last 6 tosses

this. you seem correct about those addresses, but ken's history shows he rarely acts in the company interest. As is there are 163x 500GH prospector boards still available for sale at $2000. Thats 80TH of mining power that should be in the eligius farm or sold at a lower price to cover refunds.

My understanding was that the MSD made it pretty clear that ken had to put a halt to his questionable activity and send refunds. This is not that.

can't believe i missed this little nugget before - what sort of startup CEO invests money in private machines and not in thier own company?

oh yeah, a CEO who has a history of deceptive tactics and builds his company entirely from investor money and not his own.

displacing 10-20TH of equipment from the public mining address for a few hours a day means significant losses to ACTM holders (and significant gains for any address that the miners might be pointed at during said outages).

either Ken is stealing hashrate/income right in front of us, or is incapable of getting his farm to run stable.  My own eligius page is a perfectly flat 7TH line for a week now, none of this nonsense that kens running.

I will offer 0.05 BTC for a $400 coupon to you or anyone else with one.

(I have no idea why i got no coupons from bitmain this time around - the last time coupons were given i received 21x S1 and 21x S2 coupons that all expired at the beginning of june.)

shipping the S1 to canada cost bitmain about $120 if i recall. So by shipping only boards they might save ~$80 at most, and it would require virtually discarding your S1 (which is still profitable for several months)

so it moved to an actm account, but no explanation for where payments of 58 and 6.8 BTC went from there and why.

I would have thought that the MSD issues prevent ken from moving money around between shell accounts. From the sidelines this looks like scamming at its finest, and the fact that ken has a history of shady companies and con tactics just cements that opinion

phased out for the S3 (and perhaps a re-designed ~3TH/2kW S4?)

the difficulty increases are no longer 18%/jump. Its closer to 14%/jump if you average the last 5 or so, and its visibly decreasing. (the network is no longer doubling every month - not sure if anyone noticed it now takes 7-10 weeks per doubling)

I would pay 1BTC for an S3 - possibly up to 1.1BTC if it DELIVERS before the end of June.

IMO, they need a larger S4 device similar to the S2 but better optimized for hashrate and without the shipping issues. If they could pack 4TH/3.5kW into a 4U case for ~8BTC i would be very interested. These little <1TH machines will very soon be worth less than $100 each and will require large awkward stacks of them ziptied together if anyone wants to operate a farm with over $10,000 of equipment

The SP30 will be 6TH / 2.8kW / 2U very soon - bitmain needs a similar pro-level mining device. The S2 wasn't terrible, but the chips were a little too undervolted and the unit wasn't built well for shipping with fumbly couriers that kick or drop their cargo.
