[ANN] Spondoolies-Tech - carrier grade, data center ready mining rigs

[Biodom]

Is it safe to say anyone that is running their Sp2/3's at a data center right now, is losing money? (users with free electric not allowed to answer).

Usually you pay for hosting in advance. If you paid last May for a year of hosting, you're not loosing anything if you keep your accounts in BTC. If you pay monthly about $80/KWh/Month .. you're still making something ..

With a  SP30 on Eligius you're at 0.04734934 BTC/day. That is 1.42BTC in 30 days .. that is .. $311/mo, while an SP30 is about 3kW at the wall .. aka $240/mo.

By now my SP30 made 9.19100781 BTC since powerup and I received about 2BTC back from SPT as compensation. Overall ~1 BTC more than I paid for it. It still has to run a while to cover the hosting .. or I might sell it for something and get the ROI.

With another one on the paycoin route .. everything ROI'd already.

this is a bitcoin-centric way of calculating things.
try the same calculation in $$-it is worse.
even if you use a mixture approach; $4500 for SP30 minus $800 compensation=$3700.
~$300 (hosting per mo, probably average number)X5=$1500 in hosting fees.
$3700+1500=$5200 for 9.2 BTC
maybe you can recover $1300-1400 right now
$5200-1350 (average between 1300 and 1400)=$3850 in $$ expenses for 9.2 BTC
essentially, you purchased your 9.2 BTC for $418.5 average.
not the end of the world, but higher than current.

^its all a risk.

IME, most colocations are >$100/kw/month in USD and thats pretty expensive, about $0.15/kwh and often taxed.

however, the good ones (<$85/kw/mos +tax) are still quite reasonable and products like th SP3X are great there. The Sp31 provides about 4.7TH/3kW (at the wall) and can even do 3.5TH/1.75kW (wall) for fuller racks

Lets make things interesting by calculating an average of 3-4% diff jumps every 13 days @ .11 kw/hr.  Mined btc drops by 40% in 90 days.

try the same calculation in $$-it is worse.

if you add the BTC depreciation since May 2014, of course it's worse. However, I bought the units with BTC (actually converted LTC mined with GPU cards since 2012).
It's tough to do all the calculations in USD or CAD for that matter, I mined them over the years .. What I know for sure is what I spent for electricity and/or customs fees on new hardware. It's a good chunk to support my "hobby" .. but there are more expensive hobbies out there.

Else, BTC is still "monopoly money" .. having real value only when you cash it out .. and after you pay your taxes.

Adjusting the profits with respect to the difficulty will not make the things interesting .. only complicated. And the result won't be a profit and loss report, but only a forecast. You just need to report your cash flow in the currency you choose .. then you calculate what happened.

those diff jumps will grind to a halt quickly though. unless the price pushes past $250 its unlikely difficulty will exceed 55B until the next generation of hardware is available.

once spring comes and things warm u, a lot of home miners have to sell or turn off gear to keep cool and save money when summer electricity rates begin

Its not just home miners, big farms and their speeds are impacted by the heat as well.

Remember not all miners are in the northern hemisphere.  It's slowly warming up on the top side of the planet, but the bottom side is slowly cooling down.

While that's true, I'd be really surprised if there was much large scale mining going on in the southern hemisphere.  Power prices in Australia are outrageous, as well as most of South America.  I don't know how power pricing runs in Africa generally.

We're out of stock on the SP35.

Good product!

[bigblind]

Is there any dbA measure of the SP20 running at 10% fanspeed?

[takagari]

We're out of stock on the SP35.

So next gen soon?
Use a built in psu that's common like the dps2000, and ship without them? let us buy our own, Big savings there

[aclass]

Nope. This will be a HUGE mistake if done. One can source 10-20-50 PSUs, but how about a few thousand of PSUs?

Maybe, but the option could be given. I for one own a number of power supplies, so paying $800 more for the sp30 to get new PSU, and the extra shipping weight?
Be a nice savings point

[mavericklm]

dps2000bb is very nice psu! the 2.88kw looks good too but is too noisy

You do realize that half of the world is in the southern hemisphere. How do you come about your assumptions?  

[takagari]

... I think he is meaning population...

Overwhelmingly, the Northern Hemisphere has the greater population.

Northern Hemisphere: 88-90% of the population
Southern Hemisphere: 10-12% of the population

Greater landmass as well, 68% of land is in the Northern Hemisphere.

Because I've built datacenters in Australia, Brazil and Argentina as well as in Europe and the US?  Dealing with electricity costs and stability in the southern hemisphere in my experiences have been far more difficult than in the North.  Electricity costs for industrial electricity are above $.11 USD in most of South America whereas in China and the US you can find electricity for about $.015 USD for industrial in certain areas.  Something else to consider is almost 90% of the world's population lives in the Northern hemisphere.
