Specifications:

•    Technology: Global Foundries advanced 65nm technology (IBM core)
•    Die size: 7.5 x 7.5 mm
•    Substrate package: 10 x 10 mm

Advantages of Butterfly Labs chips:

•   1/2 the power usage per GH as the closest competitor
•    1/10th the silicon area per GH as the closest competitor (Very high performance density)
•    Proven design currently operating in the field and ready to go.
•    Unlike some QFN packages which require underside heat sinks, you can use off the shelf heat sinks due to the FCBGA package. No need to design and manufacture heat sinks!
  

Details

This group buy is for a total of 100 Butterfly Lab ASIC chips. Once the total paid orders reaches 100 chips, the group buy will be closed and any remaining participants will either be refunded their order amount or be given the choice to participate is a subsequent group buy. The remaining amount of chips will be updated in this thread.

Once the group buy is closed all sales will be final. While open, refunds may be requested, but not when closed.

I reserve the right to change the price per chip as BTC is a fluctuating comodity and BFL only sells their chips for US$.

Shipping is not included and any import/customs fees are the sole responsibility of the buyer. Local pickup is acceptable Detroit, Michigan, USA).

What can you do with the chips?
Build an awesome bitcoin miner of course!
They can be placed in unpopulated chip positions on BFL (Butterfly Labs) mining boards. (I will offer this service once I prove it can be done on my own BFL board)
They can be used in DIY or open source BFL type mining boards

If you are going to purchase or have purchased an Avalon ASIC based mining board and are unsure of your ability to place and solder/reflow your board(s), we can do them for you.
If you have purchased Avalon ASICs in a group buy and need to place them on our fully assembled board, we can do that also.
If you have purchased Avalon ASICs in a group buy and need to place them on your fully assembled board, we can do that as well.

Note: All of these services are a Bring-Your-Own-Chip service. As of yet, I do not have any Avalon ASICs available for purchase.


We will be able to build both the Klondike 1 (aka Nano), a 282-350 MH/s USB miner as shown below. This design has been tested and the production board has been released. All parts are in hand or in shipment.

bkkcoins, the designer behind the Klondike project, will also have kits available for purchase. While we will have parts available to populate the circuit boards (except for the Avalon ASICs), please feel free to support bkkcoins and his effort by purchasing his kits; we can build them up for you.

If you you have a broken Avalon based mining board, we can remove and replace the Avalon ASICs for you.

We are USA based, in Michigan, thus the mitten reference. Turn around should be within 2 days, holidays and weekends permitting. We are not in this to make a killing, just provide a much needed service at a reasonable price. I am an electrical engineer with many years experience in prototyping and testing automotive electronics. In recent years I have spent many months in China supporting PCB production and testing in automotive applications.

Since we really could be called a fabrication facility, any board can be assembled for any of the DIY mining project. Please feel free to contact us regarding other projects.
