1.3 Technobit NanoFury USB miner - 52 EUR

1.4 Technobit NanoFury assembly service with your chip


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 2.3GH/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 , 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.

Hi ,
the order of the reel is made

Hey Martin -

Are the bare chips which are being offered @ technobit.eu already purchased?
Or are payments going toward another reel which will be purchased once 3000 are sold?

thnx!

Yes I know, I am watching your work which is awesome. I agree with your answer. And know for 3k of chips is around 190 pcb boards what make them cost more as considered as low amount. When add parts and assambly cost, designer and marto fee there is not a lot of space for price drop. MAybe on larger scale 

Well, it was made months ago, but there were no chips for sale for large scale production. Even now, the 16 bitfury chips cost 50x as much as the ARM, so it's not such a big deal.

After the chips, the most expensive component is the power regulator module, and you'll need something like that for better overclocking of the h-cards.

I have an question...
Why to make a standalone unit with arm chip what just addup to the total production host. 40ghs as stanalone would be nice to have a couple of months ago, but miners what ship in mid october should be orientated from around 80 ghs.

Is there a simple way to use h-boards but to design motherboard what will be support overlocking with higher voltage regulator and where you can attach more h-boards? I am aware that ARM is not expensive but all those nice features should be only on one motherboard with extension possibility of adding more h-boards with 16 chips.

A bit playing around at home with the prototype:

Here are some pictures of the assembly process of a prototype, including picture of final result:

Hey guys,

just ordered two boards.

was wondering if we could have some more (possibly in focus) pictures of the board please??

Thanks

very excited for the project!!

Yes

Hello,

Maintain delivery forecast chips for the first week of October?

thanks

regards

We are now accepting pay pall payments

Okay so lets say people can start mining at the 3. week or OCT. If everything works as planned.
But still there is a lot in common and its a big risk to buy it even when receiving it on third week of October.
(After all that BFL and Avalon shit, people are sick of sharing the whole loss.)

I dont want to convice you about dropping prices i want you to think this through:

There are a lot of customers who planned to buy bitfury burners, but got screwed by burnins new distributor cryptX and his big margin.
There is a lot of hate comming towards the good name of burnin because of false statements and (not purposely) misleading.
If you are able to reduce the risk on the buyer side, by for example lowering prices, there will be much more people buying your board and giving you the trust you deserve.
And if they trust you once and it worked, they will surely trust you next time on the new Project.(May it be cointerra,hashfast, bitfury or even technobit chips )

You prooved with your Avalon Hex Board running at 450mhz that you are capable of doing boards.
People have seen that and will recognize your name for that. So Hopefully dont make the same mistake as burnin did with his new "distributor".

Regards

The statement for 2-3 weeks is after ordering the PCB
If the chips are here first week of OCT I'll start shipping 2 week of OCT.

Hey Marto74,

you said you will get the chips in first October week and will need 2-3 weeks to assemble the board.
That means we can start hashing on first of November.
Based on this information and the given price it is not possible for customers to ROI.
Not even mentioned the risk if KNC, CoinTerra, Hashfast or Bitmine will start to ship between October and November.
Please watch yourself:

I really like your design, but its the same discussion going on right now with Burnins Bitfury board and his new shady distributor.
It is not able to get into a positive balance with that price.
In my opinion there should the a golden mid when dealing in B2C fields, where both sides are able to into a green zone.

All miners here are sucked by blood through BFL, Avalon and the now upcoming firms.

Please share your thoughts.

About 4 A @ 12 V
So about 50 W

What is power consumption?

I'll do that but first next week I have to source them

Could you please answer that?

I asked C-scape for revised PCB design with copper pads on the back of the ASIC chips (Avalon style) in order to make better contact with the heatsink.
I got it a few minutes ago. We'll order test board for this tommorow
So yes in reasonable limits I'll allow OC-ed miners in the hosting facility .
