Re: Reviewing the Halong Mining DragonMint T1, a 10nm SHA-256 Miner

Measure the DC voltage (if any) between the individual heat-sinks; while operating, but open, with additional external desktop fan providing additional cooling.
I'll try to accommodate this. Unit wasn't friendly with me when I had the fans disconnected or even connected, will try a workaround.
You can probe just a few random heat sinks while
all boards are normally mounted in the frame. If it
is anything else but 0V, we can run some calculations.

There is a huge inductor on the PCB so it looks like
there is a DC/DC converter on board. Can you read
the chip number of the chips that are directly under
this inductor on the other side of the PCB?

Just installed 0.96.3.99 (noasm version) on Kubuntu and running core 0.15.
Imported my old Armory wallet files and the balances show up as 0.0.
Any pointers how I can fix this?

Wait until both bitcoin-core and armory are fully synced. Check the lower right corner of armory for status (offline, online, synced until what block).
Ente
Armory signaled 'Armory is online!' while bitcoin-core was still syncing.
That made me confused, looks like all is fine now.
I could sell you a bunch of these ancient beauties, unfortunately use and value might be restricted to antiques markets, or/and (* squints at your username *) collectors 
They where once at 350 a piece. Some people paid over BTC300 for a 400GH Miner Full Kit (August Delivery)

note the v1.2 and connector type (that is a collectors item)

You might want to check out our 28nm designs that we just released under CC-BY-SA license.
Nice:)
Is there an NFC circuit on this board?

... Makes me wish I had a longer hub so I could run all 11 functional sticks together and get slightly more sex appeal out of it...
A bit like so you mean?

Good luck with your design:)
Just a proof of principle, playing around a bit:)
Gotcha - would be a neat little addition to ad-hoc point-of-sale terminals without the cost overhead of full-blown bank-sanctioned ones.And it can do micropayments. Try paying half cent
for something using a normal terminal;)
Hi, this is really cool but.....
What can you actually get for half a cent nowadays?
In fact, can you actually get chewing gum with 50 cent nowadays?
Make it nine Euro cents then for a popsicle;)

Some juice to charge your mobile phone, or some
drinking water, or some air to inflate a tire etc:)
It could be a method of making really small
payments in the physical world.

True - I was just thinking that because you need the vertical height for the bluetooth module anyway, one might as well stack, a la: http://i.imgur.com/gDrh7r4.png

I see now. When the performance of the NFC antenna
is not degraded it could be done I guess.
And it's WiFi btw, not bluetooth:)
Regardless, though - very neat Just a design for now, or planning sales?

Very neat. If the board antenna +chip can be moved up, that would make for a tidy package to build a case around
The board measures 34x74 mm, think a case can be tidy enough:)
Made this, a small and low-cost btc payment device:
It has WiFi to connect to the internet and NFC to
communicate with a user with a mobile phone. It
can be used to handle small payments and to perform
a simple task when a payment is received. Cost price
can be well below USD 10.

On Intel D54250WYK NUC with 16 GB of RAM, we're getting about 100 TH/s.

Do you only get 50 TH/s with 8GB or RAM?
So it's more then 50 TH/s with 8GB of RAM then?
Estimated Next Difficulty: 40,248,405,371 (-0.13%)
I never saw this before:)
The difficulty declined twice last year, one of which was ~this time. I never saw this before:)
With those two exceptions there was only one other time that the difficulty decreased in the history of bitcoin, although it did stay the same for several months (at "1") in the very early days of mining.
I counted 18 times that the diff decreased on adjustment, just some of that:
8 times in august - november 2011,
4 times in april - may 2012
2 times in december 2012
and once in january 2013
I wasn't around at that time, so I never saw this before;)
