Topic: [CLOSED] NanoFury NF1 USB stick - Group Buy + Product Assembly - page 14. (Read 74354 times)

Sounds awesome, im currently waiting for some money from a GB. After that i will order all my miners from marto. Cant wait to see them

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.

Watch 
good luck

So that means the pcb and its components are pretty stable, right ?

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.

so do you have a working stick to show?

I'm In for 3 assuming max price of 0.6btc
PMing you momentarily.

How is the latest situation about price ?

In for 20.

Thanks for that clarification, helped me a lot.

 okay sounds good.  I will have 4 coins on thur the 26th,   thank you.

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.

That is mostly correct - the highest price that we're looking at (currently) is actually 0.55BTC so that would be eventually 1.5BTC more (plus shipping).

I decided to buy from you and from ssinc.  spread the risk.

I will send in 4 btc on thur. the 26th this would be  for 10  fully assembled sticks all parts  provided by you.   

 you would then come up with final pricing on the 3rd of oct correct. and since sticks may be as high as .6 btc I could owe 2btc more? 

  If I have it correct please confirm.  thanks.   phil

What is the preferable buying option now: through http://technobit.eu/index.php (which lags horribly and shows nothing at the moment) or this GB? Thanks.
Upd: Sorry about lags, next time it opened blazing fast! Not sure what that was.

Yes, indeed -  we've set up a second distribution and manufacturing point in Europe and are working with Marto74 in that regard. Have I mentioned before that we listen to our customers?

We're still shipping to the entire world (or more precisely wherever USPS does), and for shipping and tax purposes it is sometimes better to ship such products from EU vs US (and vice versa).

By the way - he announced it on his thread too - https://bitcointalksearch.org/topic/m.3201837

I see TechnoBit is selling NanoFury's in EU.

Will you be selling the S-Hash in the US?

this seems like only a few people have sent in coins.

in contrast the other buy for these sticks uses:

https://blockchain.info/address/1LRUwL1sF5j4DPjXrkVGGiDGFd7qGVqwGX

  and that address has more then 60 coins placed into it. The other seller wants .85 a stick so for me to buy 20 sticks it is 17 coins I get them lets say  Oct 2- oct 10th. 

Your sticks are lower cost I like that but they come Oct 30 - NOV 4th

 Frankly as a person still waiting for my bfl orders from Jan of 2013 sending 12 coins to you for 20-30 sticks is kind of hard for me to do. 
 

Not only am I waiting on bfl. 5 coins
 I am waiting on knc.            7 coins
 I am waiting for a baby jet.   2 coins
I am waiting  on a metabank. 3 coins

most of the above is group buys from this site.


I am not sure I want to tie up 12 coins for a long time say 42 days. Very frustrating doing business with asic providers.  It is almost always hurry up and wait.

 So as much as I want to pay .4 to .6 a stick I will most  likely pay .85 a stick to the other seller. Not my first choice but it looks safer.  If I order here it will be 2 or 3 sticks tops. I can deal with waiting on a small amount of coins for gear.

Are the confirmed and pending confirmation orders payed to a different address?
On the blockchain there are only 6 transaction with a total of 7.2btc on the payment address: 1AHvViTD5wohPywNYHi8NZ8uPhbY9dZXCY
That would be 18 fully NF1 devices at 0.4btc
