I've got 2 Hab boards and 3 hex4m boards that I want to consolidate into Sp20 gear. I really like the sp20...  Very very nice.

you could always put a shine to those turds

SP20 in hand, ordered Sunday, received Thursday!! Glad USC is now aware of the product line no need for inspections. Thanks SP-T, if my last 2 TURDS, I mean Tubes sell I will grab a couple more.

Well that explains it all.

~L)L~

Mine should be here soon.. and looks like my sp31 is out for delivery too.. 

Then its time to knuckled down for three weeks, sock the next batch of coins away and then raise more for the next lot of hardware

maybe you need to just replace those S3's and stock up full on SP20's.
 

 It would have been nice to know that before I ordered 4 times

oh well.

Buy another one and contact sales@ before. We'll ship a t-shirt.

Buy 2 devices, mine solo with the first, mine against a pool with the second.
Not everything is about ROI ...

No-No

I need as much Th as I can. 

honestly - calling solo bitcoin mining a 'lottery' is a bit silly. If you actually wanted to win, you would solo mine with the larger, more cost-effective hardware. You can have 11x the hashrate for about 7x the cost if you buy an SP20. the solo-mining lottery is really a way to sell overpriced, underpowered hardware to those who dont know better, or want a small collectible piece.

-granted, if its your first time mining bitcoin, its probably a decent device for that. cheap and power efficient. however, any new miner who goes solo will surely be dissapointed greatly 6 months later when they have nothing, and realise they should have been on a pool from the start so that they would have at least made a fraction of a bitcoin, maybe enough to pay for the electricity used in that time period (probably $60-80 worth)

i have paracetamol. thank you Steve. 

Ooh! Math(s) is fun, though!

You buy lotto ticket each week for a year.  £2/week * 52 weeks = £104.
At odds of 1:56.66, there's a reasonably good chance ( 1/56.66 * 52 * 100% = 91.78% ) you'll at least get one of the 3-match £25 prizes at some point, and be out £79.

The odds for the Dice are claimed to be  150/300,000,000, which isn't too far off, so let's run with that, and simplify it to there being a 1:2,000,000 chance that you would solve a block and get BTC25, currently worth about BTC25 * £240/BTC = £6,000 .  Rather unlikely, and you're out the £108.
Just on the face of it, 1:56.66 / 1:2,000,000 ~= 35,300 times a better deal to play the lotto to win something.

On the other hand, that something is much greater for the Bitcoin lottery, and factoring that into the odds by plugging one into the other (£6,000 / £25 = 240), multiplying with the odds (1:2,000,000 * 240 = 1:8,3333), and then dividing (1:56.66 / 1:8,333), you'd find that playing the lotto is 'only' 147 times a better deal than playing the Bitcoin lottery with a Dice to win something.

But that's messing with numbers that shouldn't be messed with as it's not a direct comparison. Let's instead compare that to the closest equivalent for the lotto - getting a 5-match four times (for prize money of £6,000);
Winning it once: 1:55,491.33
Winning it four times: 1:221,965.32
1:221,965.32 / 1:2,000,000 ~= 9 times better to play the lotto if the goal is to win £6,000.

Alternatively, a close match in odds is the 5+bonus prize of £50,000 with 1:2,330,636 odds.
Playing the Bitcoin lottery is a mere 1:2,000,000 / 1:2,330,636 ~= 1.165 times a better deal to win something, but in the lotto that particular something is a great deal more money.

The above is hugely simplified - proper statistics makes my head hurt, and I don't know the peculiars of the UK lotto in question - but overall: you'd be better off playing the lotto.

But, really, who plays lotteries based on rational thought?  Maybe you get lucky and you solve a block 10 seconds after plugging it in, and the lotto player doesn't get a single prize after all.  Or maybe they win the jackpot twice and you never solve a block.  Though if you are going to play the Bitcoin lottery, knowing the odds are not in your favor, you might as well do so with an old Block Erupter - unless you're getting additional benefit from the hardware such as heating

forget 1700 they are best with underclock, watts per gh is really good.


I have 3 running all underclocked

Got my SP20-s yesterday. I needed a little time after the Ants how they work.

I had time to fire up only 2 but what I see the average 1.6Th.

This machines need a fridge or something....

if i won the lotto, i'd buy bitcoin with it anyway, so i may as well just mine bitcoin solo.
please don't ask me to do sums, it makes my head hurt.

Anybody here that could compile/build cgminer for Spondoolies SP20 with our extranonce.subscription patch? Basically what would have to be done is to merge this patch with Spoondolies cgminer fork ... If somebody could make please post results in cgminer extranonce.subscribe extension thread. Thanks!

How does it compare to the UK National Lottery odds?

i think the Dice is most likely a tad more efficient than your Jup..? The point of it being that it costs (for me) ~£9 per month to run and it's designed more to be a bit of fun (and extra heat - I bought two for under my desk - one for each foot). In the UK a lotto ticket is £2, if you play lotto every week that's £104 per year (if you only buy one line of numbers per week). A Dice is £108 per year and i'd much rather win a bitcoin block than the lotto.
I also solo with other inefficient miners (currently a BFL Single and a Block Erupter Cube) and in the winter the extra heat is welcome.
i don't bother doing the maths of it all as long as I know what it'll cost per month to run and I am happy to pay that - it's cheaper than the oil radiator that i've used in past years and it may, or may not find that block, which would be a bonus.

hmmm...would it not just be better odds to use my 550gh jupiter device rather then the above 150gh device for blockchain lottery games
or is this specific blockchain lottery device different then a miner in some way? from my 'imprefect' math you have a 25% chance to hit
that block in 1 year.....that again may not be correct..others with better odds on math chime in

anyway at first glance it seems silly
