First/second week of october

We're running two separate business models and therefore there isn't necessarily a "better" place. There are also several factors which may affect your preference - see below.

Marto74 is taking a bigger risk by ordering a full reel of bitfury chips, and also estimating the demand and thus final price. On the other hand, because of those factors he'll be shipping a few weeks earlier than us.

We on the other hand are trying to get the lowest price by first knowing the demand precisely. That way we won't have to pre-order tons of components which may end up not being necessary. At the end of the day if our price ends up being higher than Marto74's we're going to order our devices via Marto74, and his price will be our price too. I'm pretty much trying to say that no matter where you end up ordering from you will pay no more than Marto74's price (which is around 0.54-0.55BTC based on the current exchange rate).

The other factor that you might want to take into consideration is shipping. In the second email we'll be asking the question "Shipping preference: (From EU), (From US), (no preference)". For some countries it might be better to ship from US and for some from EU. There are also often different customs procedures, duties and taxes/VAT based on the country of origin.

The only thing I liked about the led was that it made it really easy to tell if the miners were offline, I'd get up in the morning go downstairs and see a light on and know to restart that strip.

No need to have to check on the computer or ui.

A disable feature would be cool (also multicolor lights not just one color for every one of them)

No, the power regulator doesn't have a voltage adjust input. It is designed to be set using a feedback with 2 resistors, just like on the H-CARD. We thought about adding some extra circuitry around it, but we weren't sure that wouldn't interfere with the feedback loop.

Pretty much. All of the important pieces of the design are stable. In the last revision I added also an LED (as people like blinky stuff ) but this it is purely for prettiness - it doesn't affect the core functionality in any way.

Your price has a negative return. So what would motivate someone to buy your shares?  They will lose about $300 at your price. That's best case.

what is your point?  I never considered buying that system either.

May as well write:
Ferrari F430: Euro 325,000
ASIC HARDware Bitfury board: Euro 706 with heatsink

Edit: actually Euro 709 even

The nicer looking boards unfortunately won't make it until some time next week and I'll have just the engineering samples on Friday. I'll be assembling them over the weekend and if they don't look way too ugly I'll add some pictures of the finished devices.

Here is a picture that I took the other day while doing stress-testing with one of the V1 boards:

I know that at first it looks scary but it was actually a successful test. (If you're not interested in the technical details and lingo you can stop reading here )
I was experimenting with extreme values for some of the components and even in that case the communication was still stable and usable at SPI speeds of up to 200-300kHz (and as a reference - for a one-chip design 50-100kHz is more than sufficient). What you see on the oscilloscope is the MISO line after it's been converted from 1.8 to 3.3V and the effects of the capacitance of some of the components. The data was fed back to the USB controller once it was converted down to 1.8V (sort of a loopback - 3.3->1.8->3.3) which also contributes a lot to the image.

You made my day !

First  HEX16A units shiped yesterday  

@ nemercry  Yes , you can try @ 580 if you wish- a lot of HW but it's working 

This doesn't belong in the Securities subforum, you know.

Are they still for sale?

I can't see your share on pidobir group buy list.

Thanks.

I dont even know if they were shipped?!

Any news on zephirs chips?
