Nice to see a product at last, sadly it's dearer than the buying S3's which I've also no interest in

I said earlier in the thread what was needed was something like the S2/S4/Dragon/SP10/SP30 form factor, included PSU, with plenty of underclocked chips as power useage is critical at the moment and 2TH+

What are you after, just had a rumage and found the original box for the Dragon and 1 box for a Jupiter (think others may be at home), so I may be able to post some at cost price or send me a label for your preferred courier.

If you wanted everything I'd meet halfway.

All the KNC Jupiter have Padrino's custom firmware to allow easy tweaking, and I fitted ram heatsinks to the DC/DC units to keep them cooler.

Jupiter 1:
October ~600GH
£105.00

Jupiter 2:
November ~840GH
£145.00

Jupiter 3:
November ~750GH
£130.00
SOLD



Price does not include PSU's but if you want them I will sell them at 60% of the retail price.

Dragon 1TH
Out of all the miners I have had this is the best, it's rock solid at 1.02TH the hashrate graph never moves, and it requires no intervention.
£250.00
SOLD



Antminer S1
£30
SOLD

I am located in Preston, Lancashire

Postage will be at cost and I estimate £15 for the Jupiters and Dragon, and £10 for the Antminer S1

You are welcome to come and view the the miner(s) working, pay with BTC at current rate, cash or bank transfer and take it/them away

I've no problem with escrow either through squall1066 or OgNasty both of whom have excellent reputations on the forum

Wanting all that money up front is not a good sign, and is probably a waste of time and will be throwing good money after bad.

If he was confident of winning, he'd do it on a no-win no-fee basis, charge 10% if successful and make a few hundred thousand.

Who needs an SP20, SP3x when an SP10 can go this quick (and it's underclocked) ....



 

I can do the rest but can you put the command back in for that, sorry know very little about linux.

And thanks for your work on this

I have something weird going on with one of my SP30's (the only one on firmware 2.4.21 which may be the cause)

Hashing fine at 4.5TH...



However the API is reading the input temperature instead of the output, and it's the wrong speed.



Is there a repository of firmware that we can download so I can roll it back, looked on the website and couldn't see any links, and the manual firmware selection doesn't list older versions

Thanks I might give it another go when there is some new hardware that's expensive and in demand.

And Coopster8888 now refunded

Just waiting on confirmation of Coopster8888 bitcoin address to refund

According to my accountant and HMRC you cannot claim VAT back on mining machines UNLESS you are buying them in to resell.

The simple version of the rule is that you can't claim an input unless it generates an output, which because as you say there is no tax due on bitcoins mined or sold means you can't claim it back on the hardware used to produce them, this also means that you cannot claim the VAT portion of your electric bill either.

If your accountant says different it might be worth clarifying which position is correct, as you are no doubt aware errors made in regards to tax are not treated lightly here.

With the recent drop in btc (thankfully recovering !!!) I did a big spreadsheet analysing every aspect of my mining operation.

One interesting factoid, out of all the machines I have from various manufacturers and in different countries the most effecient miners I currently have are the Dragon 1.5TH, which even at the old $110 monthly fee only swallow 43.46% in running costs, the next best are the spondoolies sp30's hosted in the USA at 46.61%

All in all been very happy with the service received.

It seems that way, still you don't know until you try

I don't think it's a trust thing, I think it's more that the first batch of S4's are having quite a few problems plus it's not that good a deal at BTC4 so even though the odds are good in the raffle itself when you factor in the real value of the S4 it might not be as appealing, I dunno.

Anyway I'll give it to the weekend I think and if there is no interest I'll see if you and coopster just want a refund and I'll close this.  I can't see Bitmain ever selling out of this at the moment so it'll save this dragging on for ages and keeping yours and my btc locked up.

zvi,

Given the fall in the btc and high electric rates here I've changed my UK machines to "slow fans, medium rate"

SP10:
Before 1425GH / 1280W = 0.8982 w/GH
After 1160GH / 880W = 0.7586 w/GH

SP30:
Before: 4500GH / 2900W = 0.6444 w/GH
After: 4050GH / 2420W = 0.5975 w/GH

Those have made a significant difference making the SP10 in particular profitable to run again (just).  I was wondering if you could work your magic and have a best effeciency setting that automatically tunes the machine to achieve the best w/GH possible as that's the most important thing at the moment rather than outright speed.

I completely agree that the S4 is way overpriced at BTC4+ that's why I thought the raffle would be a good idea, I wasn't actually expecting to make anything out of this one as it was a test to see if there was interest.

It was orginally posted in the Marketplace, Goods, Computer Hardware forum I didn't even notice this sub-board that we are now in was here.

As for fair, as per the first post all the names will be entered into the random.org third party draw service who will pick the winner, I suppose I could video me doing it if people are really paranoid

Good luck to you both.

Nice to see that bitcoin has continued to fall, so now it's already a losing deal for me as purchase + shipping = BTC4.063

Still them is the breaks as they say and I WILL NOT be backing out

That's my address for receiving the entries (and will be used to pay for the machine), squall holds the BTC6 at his address


As per the first post, I was going to enter all the names into the third party draw service that random.org provides and let them choose the winner.  I thought this would be easiest as it takes any decisions out of my hand and there is a public ledger of all the entries and the winner.

The entrance fee is fixed, but I want to make sure that there is an escrow in place before I begin accepting entries so people have confidence it's not a scam

Neither, because I bought them this afternoon

Neither anymore
