PREORDER IS NOW CLOSED

UPDATE OCT/7 : We've now ordered all NanoFury NF1 devices for manufacturing. Everyone that placed an order has been sent an email with instructions for the second payment (which was also due to bitcointalk being down for several days). If you placed an order and did not get one with those instructions please send an email and PM to vs3 just in case and we'll get back to you

UPDATE OCT/2 : We'll be announcing the final price at some point tomorrow (while we confirm actual component prices today and tomorrow).
As announced on Oct/1 we can still accommodate a few more orders but they will not influence the price anymore. Cut-off date for any additional last-minute orders is Oct/6.


UPDATE OCT/1 : We might be able to accommodate a few extra orders before we've purchased all components.
Any orders received after the final price has been announced will be required to prepay them in full.
We'll be ordering all components and services on Oct/6 and there will be no exceptions after that's happened!


Orders placed after that will be automatically cancelled!




Group Buy And Product Assembly Announcement
for
NanoFury NF1 USB stick using 1 Bitfury chip offering approx. 2GH/s

(see second post for all technical details and third post for FAQ)






There are 2 options with this group buy with the following pricing:

- Assembly service only: You supply the chips, we do the rest. Includes full PCB assembly, PCB and components based on the NanoFury NF1 design.
Final price will depend on the quantities in this group buy. Current estimate is 0.3BTC (for less than 500 devices) to 0.2BTC (for over 3000 devices).
- Fully Assembled NF1 unit: Utilizes 1 BitFury ASIC chip to produce approx. 2gh/s per unit. Includes one BitFury chip and assembly service - full PCB assembly, PCB and components based on the NanoFury NF1 design.
Final price is currently estimated to be in the 0.3-0.6BTC range (depending on total quantities this GB attracts) and price of BitFury chip (currently anticipated in the 0.2-0.3BTC range pending announcement happening supposedly this weekend)

Above prices do not include shipping.

- PCB or DIY kit
option: PCB only or PCB and all components in unsoldered form for those who like to solder. Please contact us individually with requests.



Payment (2 stage):

stage 1: Pre-order at 0.4BTC per NF1 device or 0.2BTC per device for assembly-only service. Closes Oct 1.
stage 2: By Oct 3 detailed final price including shipping options will be determined. By Oct 14 you'll be required to pay the remainder of that price and your pre-order price.



Target dates and anticipated schedule:

- Oct/1 - End of pre-order.
- Oct/3 - Final pricing announced (including shipping).
- Oct/6 - Components ordering. No cancellations after this date.
- Oct/11 - All Bitfury chips must be received for the assembly only service.
- Oct/14 - All components sent to assembly factory. All orders need to be fully paid.
- Oct/28-31 - Finished products received from assembly factory. Start of testing and shipping.

Note: all this presumes that everything goes as planned. There is always the possibility of something getting delayed which may cause the dates following it to slip. We have a few days of buffers here and there and hope that if any slippage does occur it will be limited to a week or so.

- All purchases are processed in a First in, First out queue.
- Address signing is required for dispute settlement.
- We assume no responsibility for any issues that may arise due to circumstances outside our control, including but not limited to buzzdave failing to ship, shipment being seized by customs, shipment arriving late, etc.
- All NF1 devices will have a warranty against manufacturing defects for 30 days. There are no other expressed or implied warranties of any kind. Any modifications to the board void the warranty.
- You may choose to change your address a maximum of two times.

Important notes. Please Read!

* 3000 devices is the target volume for this GB (50 have already been pre-ordered by myself Smiley )
If there are less than 300 orders we'll consider cancelling the GB and issuing a refund. We’re open to this discussion even if number of orders are a few more or a few less.

* Pricing is based on $120/BTC exchange rate as per Coinbase. If exchange rate changes significantly we’ll adjust the prices accordingly. That’s the exchange we’re using for now and that’s the rate that will matter.

* The prices above, including the BitFury ASIC chips, are tentative and subject to change pending finalization of all parts required. Each item which price has not been finalized includes an increased margin reflecting this uncertainty, and may be reduced.

* If final prince ends up being less than your initial deposit we’ll refund the BTC difference.

* Cancellations: You may cancel your order at any time prior closing of the group-buy. No cancellations will be accepted after that since we would have spent the money on the parts and services. All cancellations and refunds are subject to a 1% fee (which is how much we get charged).

* The NanoFury NF1 project is currently in a testing phase. Within a week or two we’ll know exactly how much hashing power it will produce, potential heat issues and all other details and limitations. We’ll be posting regular updates to this thread about that.

* We are a small team and have daytime jobs that give us enough free time to run this project. We also sleep at night. So please cut us a break if we don’t reply to posts and emails right away. Smiley
We will however try to address all questions and emails in a timely manner.
We're in Southern California, so expect most of our posts to occur in the morning and evening hours (Pacific time).

* We’ve seen what happened to Avalon and BFL preorders and we’re absolutely committed to not repeating their mistakes!
We will not spend a single cent of your money until we know that we can deliver what we promised! And if we can’t we’ll be refunding your money.
Currently there are two gotchas: 1) We are dependent on buzzdave (megabigpower.com) to deliver chips on time, and 2) we are dependent on him for reasonable chip pricing. Regarding #1 he has already stated that they have plenty of chips in stock, so currently our only concern is #2
.



Purchase instructions (or HOW TO PLACE AN ORDER):

Until we get our online shop up please use the following procedure:

1. To calculate BTC required: Multiply the number of NF1 boards desired by NF board price (either Fully Assembled NF1 or Assembly-only service)
2. Send payment to: 1AHvViTD5wohPywNYHi8NZ8uPhbY9dZXCY
*Note* Do not send funds from an address you do not control. You will be required to prove ownership of the sending address upon request.
3. Sign and Email: nf1order[at]nanofury[dot]com (and just in case send also a PM) with the subject “NF1 Order”, and the following information in the body:

Technical details

* No external power supply is required as the board is USB2.0-powered. If you want to run multiple units via a powered external USB hub you’ll need to get that separately. Powered USB hub is not included in this GB.

* For the same reason the hashing rate will be limited to about 2GH/s. (This is because the device can draw no more than 500mA from a standard USB 2.0 port). At this point we estimate that we should be able to achieve roughly 2GH with those power constraints, even though the chips have demonstrated up to 3.2GH/s. It is also possible that due to those limitations we may have to run the chips at a slightly slower hashing speeds (most likely not below 1.7-1.8GH/s), which on the good side will be controlled via software (cgminer) and depending on your specific USB hub you might be able to squeeze out a few more hashes.

* Overclocking: the board does permit some overclocking (with hardware modifications - see also “pencil mod”). Be aware though that if this exceeds the limits of your USB port your computer may just turn off the port completely. Also, with increase of speed you will get more heat. The chip and board is designed to use the back side as a heatsink, but if that’s not enough you may have to add an additional heatsink. For example - an external powered USB hub or a USB3.0 port may provide significantly more power, so if you want to you could experiment with higher core voltage (currently 0.81V).

* Final product will be a fully assembled and working board. There will be no (plastic) housing or heatsink as those just increase the price. At the announced hashing rate the board should not need any additional heatsink or cooling. Even though there are no harmful voltages on the board it is highly recommended that you avoid touching any of the components while running (mostly as you may disrupt the USB communication).

* Electric shock warning: If your computer is not properly grounded touching the board (or for that matter any metal part of the computer) while your computer is plugged in the wall outlet may result in an electric shock!
Please be safe - plug the device(s) in this order: first turn off and unplug your computer from the wall outlet, then connect all devices and then plug the computer back in the wall.
For unplugging the devices follow the same order - shut the computer down, unplug from the wall, unplug any devices and then plug the computer back into the outlet.
Even though modern power supplies provide proper insulation and the above scenario is unlikely nothing can guarantee that a power supply won’t suddenly go bad. So - PLEASE PLEASE PLEASE BE CAREFUL!

Wouldn't this be in the group buy section. Also looks similar to the k1. Good luck.

To be honest - I couldn't really tell which option is better since this is both a custom hardware _and_ a group buy Smiley.

And yes - the design is based on BKKCoin's K1 in terms of physical dimensions. We also kept the heatsink holes exactly the same - that's in case if a heatsink is needed so that we can reuse the same parts.

interesting project ...

did you have a working prototype ... ? to test heat, power drain and hashrate ...

I'm unsure but from my experience, already getting 2 GH from one chip drains a lot more power and generates a lot more heat, then what they are supposed to use in there normal 1.5 GH running mod.

Did you calculated with that? ... Just looking at my own boards ... 1.6 more power drain .... fully cooled the pcb temp. went from 41° to 49° ... having front and back fans with 1200 rpm .... and most of the chips are still running under 2 GH ...

To be quite honest I'm not concerned as much about the temperature. If we have to add a small heatsink - so be it. They're cheap. The board is already designed for one, so it will be just a matter of choice. The goal here is to get the most hashes for the $. If adding a $5 heatsink will get us 0.5GH more then that might be worth the effort. If adding it will give us 0.1-0.2GH then maybe not as much.

There were also plenty of notes on bitfury's FREE MONEY thread with feedback and also a lot on the Russian thread. According to this:
Latest test was done to maximize performance, while keeping chip temperature below 50 degrees C. A small heatsink was mounted on the bottom of the PCB, and cooled with a fan to control the temperature.

Vcore at 0.835 Volts, resulting in 2.5A current (2.1W). Clock frequency of 230 MHz. Instead of bitfury's test vectors, a test was done with 2048 more or less random vectors. Based on 756 cores, a yield of 1512 valid hashes would be expected, but 1511 were found, so COP is very close to 1.

Net hash rate would be almost 2.7 GH/sec @ 0.8W/GH.
http://i.imgur.com/g7UTw6V.jpg

In our case VCore will be lower - 0.800V-0.815V at least initially. There are also various options for the clock settings - instead of 54 bits we're looking at 53.

Also bitfury's test results using the same board - roughly translated via google-translate:
(...)
Measurements of the errors and hash rate values were done using the first 100 test vectors , the board is not actively cooled (impressive - running on a passive 2-layer board made ​​by Rene - intron - by the way big thanks to him) (...)
So the results : (...)
0.596 V, 45 Mhz, 0.39 Amps, 0.23 W, 100 tasks sent, 145 solutions got, COP is 1.0, Ideal 0.52 Gh / s, Real 0.52 Gh / s, 0.44 W / Gh / s
0.596 V, 96 Mhz, 0.725 Amps, 0.43 W, 100 tasks sent, 143 solutions got, COP is 0.986, Ideal 1.12 Gh / s, Real 1.1 Gh / s, 0.39 W / Gh / s

Please note that the 96 Mhz looks very close to the best solution ... After I started to raise the voltage without changing the settings of the oscillator - it was on purpose not voltage stabilized and its oscillation frequency should follow the supply voltage. What is most interesting that, when the oscillation frequency increases , the error-rate remained virtually unchanged, thanks to matching the characteristics of the oscillator transistor and transistor logic within a single crystal.

0.7 V 140 Mhz 1.2 Amps 0.84 W 100 tasks, 143 solutions got, COP is 0.986, Ideal 1.63 Gh / s, Real 1.6 Gh / s, 0.52 W / GH / s
0.8 V 180 Mhz 1.87 Amps 1.49 W 100 tasks, 139 solutions got, COP is 0.958, Ideal 2.093 Gh / s, Real 2 Gh / s, 0.75 W / GH / s
0.9 V 214 Mhz 2.62 Amps 2.36 W 100 tasks, 132 solutions got, COP is 0.91, Ideal 2.48 Gh / s, Real 2.26 Gh / s, 1.04 W / Gh / s.

Did not test any further - does not seem to have enough cooling.

So getting the 2GH is not the question. It is if the passive cooling will be sufficient. If we get better bang for the buck at 1.8GH then that may be the "stock" hashrate. The primary goal here is simplicity, even if that means that we may have to sacrifice a few hashes.

Have in mind that those chips are quite "overclockable" - there is nothing stopping you from trying to get 3.2GH/s. The board would likely still work just fine except that you'll then have to add some active cooling.

If you would be willing to let John K escrow the BTC until you prove that you got it running with said specs and are ready to deliver, I'm sure you will get a lot more interest on this.

Jeezy - I appreciate the feedback. We actually did consider the idea initially. But the more I look at it the more I don't see any real advantages. Instead of the extra 2% fees you can just keep an eye on the project and decide for yourself if you want to order or not. And besides - having escrow is really no guarantee that everything will happen the way everyone expects it. (just look at what happened to all of the Avalon group-buys with escrow). Since it really serves you no advantage, while it cost (your) money, and has the potential to slow the project and other headaches - we thought we'd rather save ourselves the hassle.

With all that said I want to add that I'm open to opening an escrow if that would make any difference. I just don't see the benefit - you may as well just wait a week or two, see the videos and then decide.

We are going to upload a video showing the product in the coming week or so anyways. I'm waiting for the nicer looking boards to arrive (as the engineering ones are not necessarily "pretty" Smiley). We'll see how that goes. We may end up shooting them first anyways.

So will there be a way to overclock from software rather than having to resort to mild hardware modification? That's a pretty serious feature on the Bit Fury chips.

okay I would buy 10 fully assembled plug n play. so are we looking at 6btc for ten?

I have other questions will these run with bitminter's plug n play java client. I am running 100 asic miner sticks on bit minter as i type so this is a perfect upgrade item for me..

 10 of these would be 45 to 60 am sticks. frankly I am very adverse to any preorders no preorder has delivered correctly to me and I have 5 outstanding preorders.  so if I preorder 10 of these for 6btc how long before you want my coins oct 1 to  give the coins up to oct 31 to get gear is what I am reading.  

I am not sure I want to wait 30 days. I would have to think about it.

Please support sidehack with his new miner project Send to : 1BURGERAXHH6Yi6LRybRJK7ybEm5m5HwTr
I mine alt coins with https://simplemining.net I see BTC as the super highway and alt coins as taxis and trucks needed to move transactions.

Final price is currently estimated to be in the 0.3-0.6BTC range (depending on total quantities this GB attracts) and price of BitFury chip (currently anticipated in the 0.2-0.3BTC range pending announcement happening supposedly this weekend)

It seems punin has put up pricing for September chips, approximately 0.21633 BTC if I did the math correctly.

So the high end of the final estimated price per unit is 0.6BTC + 0.21633BTC = 0.81633 BTC correct?

Final price is currently estimated to be in the 0.3-0.6BTC range (depending on total quantities this GB attracts) and price of BitFury chip (currently anticipated in the 0.2-0.3BTC range pending announcement happening supposedly this weekend)

It seems punin has put up pricing for September chips, approximately 0.21633 BTC if I did the math correctly.

So the high end of the final estimated price per unit is 0.6BTC + 0.21633BTC = 0.81633 BTC correct?


  missed the high range which looks like it is too high for me. .

well at .81633btc  for 2gh it is okay,   but the oct 31 delivery  is a long time off.  adjustments will be:

sept 14  = 107  mill
sept 25  = 133  mill
oct 6     = 166  mill
oct 17   = 207  mill
oct 28   = 259  mill   these are 25% adjustments. 

I can get .333 ghs sticks in 3 days.

 6x .333= 2gh  =  6x .15 btc = about .9

 and I will be hashing  with the sticks by monday the 16th of sept. 

So as much as I want them to upgrade.
I will wait until sept 28-30th to commit.

I mine alt coins with https://simplemining.net I see BTC as the super highway and alt coins as taxis and trucks needed to move transactions.

dentldir sorry for the confusion - I guess I need to expand on the pricing box a bit more.

The anticipated final price (including BitFury chip AND assembly) is in the 0.3-0.6BTC range. It is made of two components: BitFury chip (0.2-0.3BTC anticipated for October delivery) plus assembly and all other components (which we anticipate to be in the 0.2-0.3BTC range depending on quantity).

So the high-end estimated final price is 0.6BTC at the moment.
