n1 work man, you should talk to cscape or intron if you need help.

I'll be populating my prototype boards with my sample chips tomorrow. Does anyone have any guidance as far as test vectors, verification, etc? My plan right now is to jump right in with this version of cgminer: https://github.com/legkodymov/cgminer

very beautiful! Any idea what sorts of costs it would see (outside of the bitfury chips)? Seems like 3Ghash/BTC speed is going to be necessary very, very soon

Looking good Intron.

bi•fury assembled and with heatsink:
It's hashing test vectors now, more to come.
intron
Note: the push button, pin header and Molex connector
are for firmware debugging only, will be removed later.

Curious - will you be removing the resistor divider from IOREF pins on the next revision of the S-Hash board?
Correct. In fact, on the prototype of the first revision, the resistor divider wasn't even mounted. Instead a small 0-Ohm resistor was placed between the IOREF pad and a nearby VDD pad.

IOREF = VDD works great.

I have 3 questions:
The level shifter in the original schematic works just fine==> the one bitfury posted?
To be safe core power was applied first, then IOVDD.==> is this needed or?
VDD => lets's forget the IOREF line. ==> so connect the VDD to the IOREF?
On the Bi*Fury USB miner we have a level shifter made from a 330/390 Ohm divider. That works fine.The level shifter in the original schematic works just fine==> the one bitfury posted?

VDD => lets's forget the IOREF line. ==> so connect the VDD to the IOREF?
I've run several chips with IOVDD = 1.8V, and Vcore = 0, sometimes due to mistakes, sometimes on purpose. Nothing bad has happened. Chip doesn't get warm, and still works.
IOREF = VDD works great.

So ive just gone true the entire topic, that took some time.

Is anyone able to put chips on boards for sale yet ?
I know of 1 who's attempting to put BF chips on boards.
[OPEN] - GROUP BUY of BITFURY Chips + DRILLBIT SYSTEM mining assembly
https://bitcointalksearch.org/topic/drillbit-system-miners-avalon-range-available-now-10499-266235
Barntech has already received sample chips but I'm not sure where he's at with a prototype board. He's in Australia BTW. Julz's organizing a visit to Barntech to check on his progress when he has something to show.
Cheers,

I'm very tempted to purchase a number of chips from Dave ahead of my October order, and hoping to get some BitFury product hashing in my farm ASAP.

Speaking of chips availability:
***CHIPS IN STOCK NOW***
NO MINIMUM QTY. That's right - you can order a single chip, or two if you want to make matching earrings.
NO MINIMUM QTY. That's right - you can order a single chip, or two if you want to make matching earrings.
But at 1BTC each !! I'm not that desparate (though admittedly if they are shipping *now* its probably a better deal than waiting until October for an H board).
Yes.. I agree .. 1BTC seems a bit too much. Although one hand this is cheaper than the $1300/10chips that was on the site before.
On another - if you get the chip to start mining at 2GH starting Sept-2013 it will make about $120-130 in the next year. (source: http://mining.thegenesisblock.com/a/a6b72e535e)
October delivery (and presuming start-of-mining on 1-Nov-2013) will make $50-55 ... so in terms like that even the $20-25/chip for October delivery seems overpriced.
The sad part is that at 50%/month expected increase of difficulty all mining will become pretty much non-profitable in 6-8 months. AND that's if the increase is ONLY 50%. Anyways - I'm getting off-topic.

Ah - thnx for the correction. The 10pc orders showed as out of stock a week or two ago.
Would be nice to see more options for smaller bulk quantities.
i kind of love these chips.

Yeah, I was kinda interested in a few too, but even the main (EU) site (I'm UK based) no longer lists chips in any quantity.
Any idea when the tinkerers might be able to get hold of some (my electronics skills are nowhere near up to your standards, but I reckon I'll be able to cope with these, at least they're not BGAs
).I heard the chips will be for sale very soon, most likely in few days.
my guess is that once they start shipping the august kits (its looking like its on schedule to ship sometime late next week!) and demonstrate that the chips work and deliver, they will open up sales for some profit (much like asicminer - people will pay top dollar for a company that can deliver working products immediately)

16 chip cost exactly same as H-board with 16 chip plus VR and other parts.

Actually he didn't say "sold out". The last he said about that was:
You may want to check with Dave - he might be able to get you some chips (if you're looking for immediate availability).
A few new things:
-I pulled down the bulk and 10pc chip sales in advance of a new tiered pricing structure.

Is it possible to get a small number of chips from anywhere for testing a board design, say 4-10 chips?
megabigpower.com was selling bare chips - sold out
