argh i had it all figured with your above link...dumped my last post...anyway

...with my 15c/kwh and what it took off my $125 gas bill in the winter....it came out to a 35% cut off my equiv costs on the electric bill ...so
it would mean I could run a miner in the winter and get 35% off elec costs to run it

again from what I figured from the savings in gas to heat house (saved 9 days in heat) and converted to elec savings equiv to get the elec cost
of the miner down (not paying those $$$ to the gas company)

..in the heat (it is in the basement so not exactly where I can use it..but hey
denial ..I'll take what I can get)...so the price w/the heat credit to run a 1000 watt say sp20


https://tradeblock.com/mining/

using the above

at say $0.7/gh in cost lets say the spondoolies sp20 is $1190  (w/o power supply) kwh for me is 15c/kwh and the elec costs (minus the HEAT applied)

runs the numbers

remember 35% less on watts in above calculator at 15c/kwh to get the supposed savings on HEAT

20% ave growth till around the middle of NOV when you probably would get the beastie....and I get a $367 usd loss (at current exchange rate of around $475)

if I just go by how much BTC I could make off the unit w/o expenses for 6 months looking at 2.59 btc so..if BTC went back to 500 usd in 6 months I'd MAYBE
break even...take the equip cost off and the elec no way

and this is with my HEAT THE BASEMENT $$$ savings

sigh

If I BUY BTC now at 475 usd and the unit costs me my guess above of $1190 usd....that would be 2.5btc w/o the equip loss above and elec of $367 or .77btc
2.59btc -0.77btc with equip elec costs above again with my HEAT savings on winter home heat that is 1.82 btc vs again the 2.5btc I could just buy now

math is cruel

anyway I probably mucked up the above and all of the above is me being obviously very very bored...but at EVEN  a 1000 usd price...you would still be down
around $308 usd loss on such a sp20 unit

anyway ugly ugly ....anyway those with better math fix/trash the above or whatever...but with my 'very blatant' guesses the ballpark figures as it were...
all to make a very nice cozy basement heated up (likely only the basement..mot like I can move the air..boiler heat) so the real savings above are also suspect..

but then again if I do get the miner I can strike back at the evil centralization of BFL/KNC and others ...strike my puny blow for decentralization!

yeah er sheesh

Kinda complicated to read but:

http://www.mhi-inc.com/Converter/watt_calculator.htm

1000 watts in 24hrs=81950 BTU.

@ 12,000 btu per 1 ton of A/C=6.82 tons (seems kinda high IMO,something is off     )  At that rate you could heat a 1500 sq ft home quite well....maybe not in snow country 

Or:

I'll do a Kim Dotcom and make a custom "SP3000 Turbo" sticker for my SP30.

SP10  Farfegnugen
SP20  Farfegnugen
SP30  Farfegnugen
SP31  Farfegnugen
SPXX  Farfegnugen

Whichever you choose pure "driving pleasure".

BFL Schadenfreude
HashFast Schadenfreude
BlackArrow Schadenfreude
AMT Schadenfreude
Technobit Schadenfreude
KnC Schadenfreude
Avalon Schadenfreude
Bitmine Schadenfreude

And this list goes on for the pleasure derived from the misfortunes of others who bought from less reputable companies.

Its my article and I pester them a bunch for info on stuff.  They were good enough to allow me to break the story first and I appreciate it so much.
I really do like the the SP20 as it does fill the gap in the miner realm right now.  Adding in they are talking a few week ship time as opposed to months and months this is a great choice. 

Now this is interesting, and the FIRST time Spondoolies (to my knowledge) have not kept us up to speed on the forum, we hear news from another source. Thanks nhminer.

good for them, why post here, just to hear the same and the same "this will never ROI"

I am deeply agree with you... 

Exciting news!

The SP20 with 0.65 W/GH has a better power to hash ratio than the S3+ (0.78 W/GH or OC 0.80 W/GH), but it's worse than the SP31 with 0.5455 W/GH, and W/GH is what matters most for me with our shitty energy price here.

We also don't know the pride yet and what Bitmaintech has in their drawer for the S4.

I'm all for Spondoolies-Tech and would already have started ordering if only predictions would show it's possible for me to reach a positive ROI.

Did I understand this right, that customers get coupons for purchased units valid for the next generation of products, or was this only on special occasion due to the SP30 not performing as initially announced?

The customers will need to consult with the PSU manufacturer.
For example, for SeaSonic X-1050 XM each PCIe connector can handle up to 324 W

Soon. Still travelling.

you will have an earful from PCI-e "purists" who will say that PCI-e is supposed to handle just 75-150W. i am not one of them, but if I order Sp-20, I will be getting some of cablez creations (16 awg two pci-e to one port-V-shape connector)-especially if using evga 1300 (which has 8 connectors).
Side comment-you guys are such a tease-why not an official release with specs/prices?

Both statements are incorrect.

You can connect 2 X 600W or 4 X 300W as well

By end of october (likely will ship last few days as before) appropriate price would be .50/ghs or less

I'm waiting for the report as well. It was quite effective for the SP10s and dragons they have.
I'm not giving full description of the method because: (1) I don't know every detail (2) It's Cowboyminer trade secrets

I've posted it to prove a point regarding power and cooling density. Edit: Although jtoomim already proved it as well  

yes, you got a right price point, especially since you are paying for a 1.2-1.3kw power supply (~$200-250)

Pictures below. The 37 are in two racks. We can fit up to 20 SP30s in a 42U rack if we also include a 1U switch. I haven't tried putting 21 SP30s in a rack without a switch, but I presume it would be feasible. Temps have been stable. Our DC is currently about 20°C at the SP30 intake. The average temperature of the air our DC exhausts outside has increased, but that's expected. The exhaust from a single SP30 is the same temp as before. A typical SP30:

Temp Front / Back T,B    23 °C / 67,69 °C
Socket Voltage               250/254 volt
Fan Speed                      80
Start Voltage                  0.67 / 0.67
Max Voltage                   0.75
Max Watts                     1340 / 1350


One or two? No. About sixty? Maybe. The SP10s (not pictured, in the racks in the back) are louder.

I'm not image tagging this one to preserve space on this page.

Yeah, isn't it crazy. This year is very strange: ~70 fold difficulty increase since last November, but more than 50% BTC price decrease.
I would have never guessed that this would be the case. I don't think that this dichotomy can continue much longer, but who knows.

SP31 is about $.7/GH, so if the SP20 comes in around $999 I'd call it a decent deal (meaning likely to break even). At $10/day that's 100 days to ROI. Not horrible by any means, especially during the winter when the heat can be beneficial for a home.

While the SP20 has what appears to be attractive specs depending on the price, it's really too little to late.

Currently 1.6THs will only earn $14 per day before electric costs and that will be substantially lower by delivery in October. It's not much better than having a handful of USB Block Erupters a year ago. 

yes, they preempted bitmain's announcement (scheduled for next week). we shall see who is the prettiest of them all...at a price.
i might prefer a couple of SP-20 to Sp-31 (which i cannot host at home), providing that prices are comparable (per th, minus powersupplies), but we shall see.
