Got it. It's a monstrosity with 3 external power supplies that I have to wire in myself... however even the power side needs to be screwed in with bare wires, and that's basically illegal to do in my country unless you're a certified A grade electrician... so I'm not sure exactly what to do with it yet  Undecided

External power supplies??  Got a picture?
It's as per the opening post, but with one extra power supply (presumably a spare/redundancy). Here's some photos, including a baseball cap for size comparison:

http://ck.kolivas.org/pictures/JTMiner/

Uggh.. wouldn't be an issue for me to wire it up here in the UK but I thought it was gonna look more like the Dragon miners (massive black box with two ATX PSUs) like bobsag got.
Sure it's easy to wire up. But it's also illegal to do mains wiring yourself here. PSUs would have been much simpler, but in fact these are much higher quality and more expensive than regular PSUs.



yes, I know our company  has arrange someone  to pick it up, wire it up ,and send it back to CK.

Also , i like to point out. JT miner spend lot's of effort in the firmware and Pi side. they use the ST MCU. the firmware is written from 0. after JTminer use the ST MCU. some vendors' solution seems to have interests in ST MCU too:)

The Pi board can drive up to 8 boards (in lab we do), and each MCU to control the two SPI high speed chain. in this way, give the whole system more flexibility and scalability. it's not a small job can be done in a very short time, actually they spend one month in hardware and software with 3 high profile engineers.  

so please show some respect, JTminer are the firmware author and some Pi's controller code talking to the ASIC boards

@QuestionTime: Why are you feared to ask simple question to Giorgio from Bitmine? You should question everyone if you have doubt or you have some purpose for the misleading information. We do not have any business with Bitmine. Also Bitmine could not even put the answer in legal term to the question:
Does Innosilicon have right to sell the chips or not?

Do you see Innosilicon on this list: http://bitmine.ch/?page_id=5204

http://bitmine.ch/?page_id=863
Designed from scratch, Bitmine’s Coincraft A1 is a third generation Bitcoin Mining IC developed by Bitmine in co-operation with a team of expert engineers from Innosilicon. Targeting the highest possible power efficiency, the A1 is made to be deployed in huge binary trees structures within large scale private or public mining pools.

@QuestionTime : everyone knows they are in cooperation!

You are always avoiding to answer the question:

Being in cooperation does not mean ownership of the chip IP.

If you check the news http://bitmine.ch/?page_id=863, you should know bitmine is just in co-operation with some Chinese company. They just bought the chip from the Chinese company and name it as "Coincraft A1" chip. The Chinese company can also sell the A1 chip. They can call it any name they want like "ABC A1" chip. So the question comes: Does the "Coincraft A1" chip means "A1" chip?I don't think so. This is something like Mcdonalds can make their hamburger and KFC can make their own too.

We do NOT buy chips from bitmine and have no business with them.

Doesn't say bitmine bought the chip from a Chinese company.

I'm assuming that the R&D funds came from bitmine and it's customers and that Innosilicon was contracted by bitmine for R&D, ergo, bitmine retains IP rights of the A1 chip. Unless the use of the A1 chip in these Chinese 28nm miners has been authorised by bitmine, what we're seeing here is corporate theft and entities being in possession of or receiving these miners, liable for a criminal offence.

Precisely, we are the owner of the IP inside the A1 chip and the major contributor to the know-how of the inner workings that led to its development. We are aware of things like the one happening here and we even made a press release news concerning this matter:

http://bitmine.ch/?p=5178

Whoever purchases these does that on its own risk and may be liable in its own country since we hold IP on that.

Yes, that's China.

Bitmine owns the chip IP, not Innosilicon.

Aye, they even have Innosilicon as a hyperlink.

It would not be a simple matter of calling an electrician to wire the machine to mains if there are no compliance marks.
Indeed not as you can see on the pictures. It's simple enough to use a different power source though. You have done well to point out enough controversy surrounding these devices, but the claim on the bitmine website is they could be a scam (they've sent me hardware, I'm not saying whether others will get hardware), or they're sending some kind of inferior or imitation product - and I can't attest to any of that.

But stolen goods? IP concerns?

The bitmine CoinCraft A1 chips used in these Chinese 28nm miners were not legally obtained from bitmine or its authorised distributors.

I don't see evidence to make that final association, but I shall ask bitmine myself.

So a non-standard PSU, do they have any recognised compliance marks?

I have a tracking number, so *something* is being sent to me, for what it's worth.
The *something* is a JTminer. Can't wait for your review.   Smiley

Why would ckolivas incriminate himself?
They asked me to review it I said I would not, as I am not in the business of reviewing hardware or supporting any manufacturer. They then offered to send me hardware, to which I said I would graciously accept it - to make it possible for them to submit their driver code for inclusion to master cgminer and have me help them. When the hardware arrives I will gladly validate that it exists, hashes etc, but I cannot vouch for the company's business in any other way since I am not a customer as such.

This may be relevant for you ckolivas: http://www.austlii.edu.au/au/legis/vic/consol_act/ca195882/s88.html

As there seems to be a demand for these Chinese miners based on the 28nm CoinCraft A1 in Australia, I've referred this and other threads on similar machines to the Australian Federal Police for some clarification as to whether it would be lawful to import and be in possession of these machines.

More vendors means more competition which is always good for customers. However customers should be able to confidently make purchases in good faith that the machines are 100% legitimately manufactured and not have to potentially face legal sanctions later on after parting with their hard earned money.
I was not aware there was anything claiming these were stolen apart from some questionable post on an unrelated forum with machine translation? If you can point me to reasonable suspicion these are stolen goods I'd of course have no interest in reviewing or promoting them - heck it would make handling them and not trying to wire them up much easier, just give them to the AFP. I'm very open about all my actions and put my real name to my actions here at all times and have never tried to hide my identity so of course I wouldn't go incriminating myself knowingly.

If you check the news http://bitmine.ch/?page_id=863, you should know bitmine is just in co-operation with some Chinese company. They just bought the chip from the Chinese company and name it as "Coincraft A1" chip. The Chinese company can also sell the A1 chip. They can call it any name they want like "ABC A1" chip.

3 suppies means giving the power sufficient to overclock.
normally it's 2 power supply. Each one is 600W .

If you run it 1T , it's 2 power supply.

We can arrange someone to wire it for you. Please check your email and discuss it privately. Thanks.
