What are the prizes for the PCB design contest?
Are there any parameters as to what you're looking for? Requirements? Anything?
Num num.... looks delicious.
Can't wait to put these into the Wasps.

Dear bitmine first congratulations for your a1 chip
It was certainly not easy to plan this and to establish but despite the euphoria over the sampling chips I ask as these are not answered customer questions:
When will the regular chips (an exact date please)
When is started with the production (please an exact date)
When the orders of December Update batch so far at most 10% penalty (please an exact date)

Wanted to place an order for 2TH, but $12k for a March delivery is not price competitive at all 
Has to be said: amazingly fast chip bring-up.
Comparing to other fail companies it is. Grats!
Happy New Year to everybody!
Thanks. You too. Looking forward to the rigs.
Big Big congratulations guys.
Those pictures make me feel all funny in my pants!!!

Congratulations, Bitmine!
(BTW: 1.6 A at 12 V means over 3.8 A at 5V, so it would be quite hard to make an USB 2.0/3.0 miner without optimizations or undervolting/underclocking.)

Pretty impressive.
So are they saying that someone can come up with 25 GHs USB adapters for this?!
Well looks like there is a PCB design contest. Very impressive indeed.

Excellent news on the chips! Can't wait for delivery!
Nice to see another product that will hit the market soon. But 0.67W/GH was achived by 55nm products so it's not that impressive anymore.
Congratulations!
EDIT:
Can wait to lay my hand on these chips. String with 10 chips in series is very tempting

It lacks an 'IOVDD' pin, setting the voltage levels
of the output signals. So making a string out of it
might be a bit more of a hassle.
But I would love to try it of course:)

Great news for 2014!
First samples of the CoinCraft A1 demonstrated working
Congrats!!
Can we buy samples to build our own boards?
I hardly can't wait...

It is really not serious, what they do!
Has anyone replied for an refund?

Id be interested in buying your unit if your interested or anyone elses if they are interested
First samples of the CoinCraft A1 demonstrated working
The results are very good: at a very first stage of testing, without any kind of optimizations on the driver and the power supply, we got it hashing stable at the nominal hashing rate at 25.4 – 25.5 GH/s. The chip was running so cool that just a small heat sink above it (see pictures below) without any forced air cooling was enough to let it run!
The evaluation board was drawing 1.655A at 12V while hashing at a constant rate of 25.4 GH/s. If we consider about 15% of losses due to the DC/DC switching block, we get a net power consumption of just 0.67 W/GH/s and this without optimizations of any kind, which are due for the next days of development.
This is the lowest demonstrated nominal power consumption for an ASIC chip in the WORLD!!!
The next step is the assembly of the first prototype hashing units, which will be done in the next few days in our production factory in Europe, for the final tuning of the boards.

Congratulations on the successful development of your project.
I am looking forward to seeing the completed product in the hands of the community.

what? Who achieved that?

The wait is finally over: yesterday we picked up the first few samples of our CoinCraft A1 ASIC chip from the IC packaging house and overnight we’ve mounted them on a simple test board that we used for initial performances evaluation.

The next step is the assembly of the first prototype hashing units, which will be done in the next few days in our production factory in Europe, for the final tuning of the boards. We don’t expect delays here so we should go very soon in production. Expect also to see a video showing a fully working demo unit with real chips on it.
Another major announcement is that we’re now officially opening the long awaited PCB design contest. Because of the extremely limited supply of this first test batch of chips, we will be giving for free 2 CoinCraft A1 chip to 10 selected developers that have already expressed their interest on the forum in the past months. All other users are of course welcome to apply for the contest too, but in that case the sample chips are going to be sent only after mid January. We expect great things to come up from it, there are USB, modular/universal and even oil-cooled miners coming out from it so… stay tuned!
Last but not least, we want to thank all of our customers for the patience and trust they have given us. We really understand that many may have been anxious these days (we have been too!), and the lack of news didn’t help, but believe me that we’ve all been working during holidays, overnight and weekends to have this product done in the shortest possible time. Everybody will be getting our promised free upgrades thanks to our customer protection plan, a unique and hopefully remarkable premium that no other mining equipment manufacturer has ever given.
Happy New Year to everybody!
