It would never be 1 core per chip. That's about 15 years ago in processor design time.
Thanks for your history lesson, but I am referring to the "soft" mining core in the Programmable logic block of the Zynq-7000 discussed in the article. Not hard-wired CPU cores.  They referenced utilizing multiple mining cores connected to the embedded bitcoind node, but they did not expand on if they were able to create multiple soft cores on a single Zynq-7000. Just a curiosity. As it would need about a 100 cores just to equal the hashing power of a USB block erupter. hahaha! |

Interesting article. Seems that they were able to get up to 3.8 Mh/s with a single core implemented. I didn't see any mention of how much headroom they had left on the SOC to implement additional cores. Maybe its only one core per chip. You need a lot more cores though to make it viable in today's world. Wonder if Scrypt could be made to work on the ZedBoard?

Ouch! No blocks for three days.  |

It shows me 0 available. Unless I'm looking at the wrong place lol
Yeah, gone now.  They were not this morning. I guess someone snapped 'em up. |

I've gone trawling through this thread to find out, but are there any batch 6 chips left to purchase?
Sorry, Batched 6 was closed out weeks ago. |

I would do 2 to play around with.  |

If the Group Buy goes forward, the best I can assume, that these will be delivered in late September/October timeframe ?

According to posts in this thread, the Chips were purchased in separate orders ( batches). You can assume that they won't all arrive in the same day. So some orders will not be able to be filled from the first batch ad have to be filled from the subsequent ones. I wouldn't worry about it too much until the expected ship date passes. |

Packaging usually comes after the chips are made, so I hear....
Wouldn't they only package the devices once they are ready to be shipped? He is speaking to the packaging of the the silicon die into a "chip". That can then be integrated onto a circuit board. |

Wow! Thats a lot of solder balls per chip. Is this amount of connections normally soldered reliably in manufacturing?
The way it works, they just set the chip on the board, and heat it up enough for the balls to melt. If you search "bga reball" on youtube there are videos of people taking the chips off and putting them back on at home. Once you put the balls back on the chip, you just have to set it on the board and heat it up for the balls to melt, IIRC. Thanks! Yeah, I am familiar with the process. I have used hot air to reflow some small packages for repair jobs. However, this size BGA is magnitudes away from anything I've experienced. It just seems that there will be have to be either automated or manual x-ray checking of the soldered packages somewhere in the process. Just asking the question from those who know, how difficult is it to solder a BGA this large in a production line manufacturing process. |

With the main board resting on a table with hashing boards plugged into it...what is the total height?
MAybe you are confusing the K-16 with the Bit Fury offering? The K-16 is a single board than can be chained with others via a jumper, and controlled by USB. See the OP in this thread for a diagram. Total height without the Heatsink is probably less than 10mm. |

What. Even the components that fit on the edge of a dime aren't that bad. I'm more worried about the tiny QFN48 package on the ASIC.
You are one of the talented people I was talking about then. ;-) Have you seen this video? Some good tips on soldering QFN packages. https://www.youtube.com/watch?v=M_rO6oPVsws |

Yes, it is the product shipping status blog from Butterfly Labs. What part do you have questions about?

No bank transfer payment option What should ppl with no BTC do ? It will take too long to buy them, even longer to mine on GPU. I use coinbase.com. Easy to transfer from Bank into BTC. |

i dont recommend you doing it yourself, even with experience. these boards are done best by machines.
+1 Yes, some of the components can fit on the edge of a quarter ($.25 USD) with room to spare. You will not be using a soldering iron on those with any reliability. Strictly Solder paste stencil, P&P, and reflow oven for these. Unless you are ***REALLY*** talented and have hands like a surgeon.  |

So its like those "asic" fpga miners? and where do i find one for that cheap? I've only found a few so far by searching but they are all in the 1.4+ BTC range... or about $130 with the current rate
I did a quick look in the Group Buy section and found this group buy for a k-1 still open for about $74.13 USD +shipping. https://bitcointalk.org/index.php?topic=254358.0 I am not affiliated or endorse this group buy, I am just passing the information. As with all things bitcoin. Please do your research before you buy. ;-) |

I must have one of these. A perfect portable miner to go with me and my laptop so i don't burn up my dual gpu anymore than i have xD
You would be better off getting in on a group buy for a K-1. Less than $90 USD for 350 Mh/s |
