The device interacts directly with bfgminer so no it doesn't have any firmware.

Sorry I have a silly question. Does the microchip PIC need NOT firmware ?  I could not find it from github.

I built a few ones for me. A friend of mine reorganised the layout. My fork: https://github.com/rgr-rgr/NanoFury. Pull request sent.

By the way: I noticed a new version v0.7, not described in the Release_Notes ... ?

I got a few of these, they run great!

Can you provide detailed instructions on overlocking?

I can't find no info online on the pencil mod for the nano fury. How do I got about doing this? Can you provide pictures with annotations?

Is it possible to do a USB miner with a BFL chip?  I am guessing no since no one has done it and they are much more readily available than BF.

Might be possible, but with the BGA packaging they used makes them a lot harder to work with than the more hand-solder friendly packages like TQFP (with the leads sticking out the sides).  Plus, BFL lists the chips as out of stock, so I imagine you'd have to buy them from someone who has them stocked up just like BitFury.

The BFL chips uses 3.2 W/GH/s so that's 12.8 W/chip for the 4GH/s chip. That doesn't fall within current USB specs but may be possible in the future.

yup - that pretty much sums it up.

As people already mentioned it - there are 2 major issues when considering it for a USB miner:
#1 - package is too big and cooling requirements are just too much of a pain for a USB miner (BF produces 2-3W of heat, BFL is well over 10W)
#2 - most importantly BFL chip consumes MUCH MUCH MORE power than the 2.5W that USB2 can provide.

Although it is probably possible to make an externally-powered big device that has fans for dealing with the extra cooling, etc, etc - that would sort of defeat the purpose of the simplicity that you get with a USB miner.

The external power is already available(plenty of 12v & 5v on one of these)

BitMain?

May be an interesting option. Could conceivably fit 3 bitmain chips on a stick

I wonder why so long between runs?

manufacturing of the chips is like waiting in line at a gov't office.....long wait

I am willing to pay a decent fair market price for any.  Please PM me if you need some extra cash or coin.  Ideally I would like to get as many as possible.



------Dave is out.  I believe I took his last one. Waiting for FedEx now. 

I'm waiting for FedEx as well. Smiley

He said in an e-mail that he's restocking in February.  Preorders available at $5/chip, but in 3000-chip batches.  Unknown as of yet if we can order individuals or small batches from the website again when he finally restocks.  Hope so...

Anyone know the best place to buy the bitfury chips in bulk?
BuzzDave at Megabigpower.com. Got a small order in 2 days. I think he has like 1500 on hand.

I was hoping for a better price with an order of 50 or so.  I pm'd me but he didn't really give any specifics.
No you have to be in the stratosphere before there is a discount.  Like 3000 or more.
