So Bitfury, are you working on any new upcoming ASIC projects ? Curious about what you might be working on next.
Cheers.
Cheers.

I'm watching for updates on that too ... I hope they keep up that promise and do finally announce the pricing.
I really hope they won't ruin their so far pretty good reputation and take the Avalon/BFL route with everything happening "in two weeks"

I'm getting concerned about that... I've designed a product around prices that were announced months ago and then rescinded, and I've been waiting approaching two weeks for $800 worth of chips that are "sorry they're expensive but they ship immediately" to be shipped. My whole model depends on chips being available early in October and near the price I expect. Bitfury chips are great, and I'm thrilled with them so far from a technical standpoint, but there's not enough margin in them if anything goes pear shaped :/
Chips came today... they shipped when they said they would, it was just the radio silence that had me aflutter I guess...
"Do they have chips" was never the question. Dave mentioned that they have enough in stock that if I wanted a reel I could have it tomorrow.
The question is "price". October chips were initially announced and available at $20/chip. Then the bait was taken away. Now they're $108/chip. AND they keep promising to announce October pricing but so far such thing hasn't happened.
A classic "bait and switch". Very disappointing.

Quote
Bait-and-switch is a form of fraud used in retail sales but also employed in other contexts. First, customers are "baited" by merchants' advertising products or services at a low price, but when customers visit the store, they discover that the advertised goods are not available, or the customers are pressured by sales people to consider similar, but higher priced items ("switching").
I think it might be a bit early to consider it a bait and switch. They WERE offering October chips at acceptable prices. I suspect they either 1) sold out due to underestimating the demand or 2) chose to hold back sales to make sure they could satisfy their requirements for 100 TH Mine and other projects. Some information from Bitfury/Punin/Dave would go a long way towards easing fears of wasted effort.
Well, to their credit I have to say that they've been pretty quick with answering questions so far and compared to Avalon/BFL nightmares are like a day and night. It is possible that there are frictions within their partnership (tytus/punin/buzzdave/bitfury) and/or conflicting interests and we're merely seeing the reflection of all that. I saw bitfury opening a dedicated thread asking for feedback on what would be a reasonable price for the chips. Zefir on the other hand is under the impression that official pricing won't be announced until the end of September.
So, there is a lot of conflicting information, and what the bitfury team is not doing right at the moment is to keep up the communication. It's been "only" two days after the weekend, but punin said they'll announce the pricing over the weekend and in terms of that promise - it failed. It didn't happen. And still hasn't happened.
My advice to the Bitfury team - When you set the expectations make sure that you meet them. You set them. You meet them. Setting our expectations is entirely within your hands. We will only expect what you promise.
I can still bear another week or so without chips pricing, but then I'm responsible to my customers for keeping up my promises.
And honestly - if you have bad news for us - then so be it. But at least please say so. I'd rather know the bad news right away than keep pulling my nerves in the dark. A bad news is not gonna get any less bad if delivered late too.
I really hope they resolve this issue rather sooner than later. I'd hate to see one of the better tems just turn into the next Avalon or BFL.

"Do they have chips" was never the question. Dave mentioned that they have enough in stock that if I wanted a reel I could have it tomorrow.
No, that wasn't my concern... my concern was that I ordered these on 9/1, and part of the reasoning behind the absurd price of these chips was that you'd get them immediately.
Ah .. interesting ... so "immediately" turns out to be about 10 days?
On a second thought - that's probably normal and okay. There was a long weekend (9/2) in between, so there are 4-5 business days between then and today. Unless you ordered a "overnight" or "second day" shipping it would take on average 3-5 business days. If they shipped it on 9/3 and you received it yesterday - that's okay and perfectly within the expected time frame.
As for October availability Dave had mentioned earlier: "we'll have plenty of reels available starting early October". That's why I didn't consider "availability" as a concern.
They shipped it on 9/6. five days is what it is, and I know they were busy over labor day weekend building and testing miners.

Project NanoFury moving along too:
I can hardly wait to get my hands on the boards
(ignore the somewhat iffy looking parts - I haven't figured out the proper 3d models yet)
By the way - speaking of filter capacitors: I figured 3 on each side should probably work just fine ... I guess I'll find out if it really does.

Do you have a thread following this development? I'd like to follow.
Not yet ... I guess I should do that
Note taken - https://bitcointalksearch.org/topic/closed-nanofury-nf1-usb-stick-group-buy-product-assembly-291456
We've just announced the Group Buy + Product Assembly of NanoFury NF1 - BitFury-based USB2.0 miner producing 2GH/s.
For now I'll be posting there all technical updates too.

Sorry guys, idle board was money lost so did a quick fix trace cut. Any good tips on how to desolder the chip? looks like it's soldered to the board with the ground pad. I have a 50W Weller soldering station. Is it possible to easily desolder with a soldering iron or do I need hot air tools?
I desoldered some avalon chips using an electric skillet fry pan by just putting the pcb in the pan and lift the chips off when the solder melted.

I though i could donate the chip to someone in the community.
Unfortunately, unless there were solder bridges on the IO pins causing the issue, the chip is likely non-functional.
nice sentiment tho
Actually mine was an interesting case. Chip 4 was hashing fine, but was not forwarding SPI
. Thus I had to cut the traces of Chip 5 first and jump the SPI. Still no fish. Wish I had a scope
. I graduated from the univ, so missing all the nice bench equipment. So I have potentially 2 hashing chips that could be donated.
If you or others are in a position to pull them safely, i definitely could use marginal chips for testing code and heat issues on my miner that I'm working on.

Lol... the shopping list is getting longer... those sparkfun guys are going to love me.
The advice/recommendations are very much appreciated.

Hehe since your pictures are good if you wouldn't mind showing what this looks like after you have cut the traces and soldered anything that would be cool.
Just in case I need to do this in the future id like to see how its actually done.
See also this example: (source: https://bitcointalksearch.org/topic/m.3099241)
(although that is a bit of a overkill)
In essence - make a narrow cut (1mm) just enough so that you can visually tell that the traces have been cut apart and that should do it. It is also a good idea to keep the cut relatively small - in case it turns out that this is the wrong chip
(yes - believe me - Murphy's laws were not invented out of boredom!)
Be careful as once you cut the traces it would be relatively easy to grab an end and just peel the entire trace off. That's fine if you're sure you'll never ever need it again (but are you?)
You can also use a small piece of wire (any wire will do) to connect the points. Or make a large slump of solder and bridge them that way. I'd go with a wire though - much easier.
Not as difficult as I made it out in my mind. Thanks for the pictures.

I don't think it would be an easy task unsoldering it. But then why would you want to do that in the first place? If you short the control signals (SCK/MOSI/MISO) then the chip will be bypassed and may use a bit of power but that's all. If you really want to cut the power - just cut all traces around it. You'll have just the ground pad left but that won't interfere with anything.
