We have just received new heatsink samples. These are fixing several issues from the first version. They now fit in a U3 case and are a little bit longer. We have also have a custom mounting base that will allow us to put 10 minions in a 360mm line.
Those are some serious fins :-)

Re: Pictures of your mining rigs!

Exactly! I find all the ASIC equipment fascinating and enjoy trying to get my hands on as many different devices as possible.

I think some of those devices might become VERY valuable as collectibles.

I bough one of the first BE USB at 2.6 BTC!!! and one of the first RF USB for 1.4 BTC!!!, because just like stamps with defects, collectors will look at the soldering of components to see the rarity and age of the item, funny how that resonates well with the 21 million rarity!

My zTex x1.15 will be the crown jewels of the collection. Early and very rare:

Interesting to compare those purchase prices with the 600GH Monarch I bought for 3.6 BTC, I'm pretty convinced that including resale collectors value; the poorly soldered, completely non ROI, crap BE will beat the Monarch hands down; those components are placed by hand and I even got friedcat to send me an original "manually tooled" heatsink from hongkong:

Comparatively the singles will fade away in history (except maybe for the case looking cool but being completely unusable) but they heat the house and feed the monkeys:

Where did you get those pretty heat sinks? Also, what is your hash rate?

Can we have more pictures, and maybe an example set up?

Re: [ANN] Bi•Fury | 5+ GH/s USB Miner [FASTEST USB MINER IN THE WORLD][IN STOCK!]

These seem way overpriced. Especially since Blackarrow is offering 1.50 USD/GH/s (granted, for March)
For March you say...same bs as Cointerra for December, Hashfast for October, BFL as always, Avalon for April...
BI*Fury's are shipped within 24h, thus the price is higher.
The price is 85 dollars a GH/s.
I bought an Avalon a month ago for 1200 USD. which is 20 USD per GH/s.
Cloud hashing on *CEX.IO* is even cheaper.
current BTC price: 706 USD. $706 * 0.069[BTC/GHS] =~ 48.7 USD/GHS

Maybe ROI calculation will help a bit more:

How is ROI calculation going to prove anything but exactly what I'm saying?

If this thing mines 50% of the BTC it costs to buy I will suck a goats dick!

depends on the price of BTC in the future.

better stick to your word.

Anybody know how to contact them? I ordered an X1 a week or two back, and I still haven't received a bitcoin address to send to.

I've opened several tickets on their support system. But no one has replied.

Re: How do I reduce hardware errors with my ASIC USB miners?

.
You are using a really cheap underpowered hub more than likely, your miners are not getting enough power and not submitting any shares at all.

Get a better USB hub, there's a thread out there listing known good ones. Either that or just buy a dlink dub-h7.



This is the hub I'm using: http://www.amazon.com/gp/product/B0051PGX2I/ref=oh_details_o01_s00_i00?ie=UTF8&psc=1

It has external power.

What about a hub makes it good or not?

See my console below, it is showing a pretty good hash rate (in GH/s, rather than MH/s)

On coinex, it says I'm getting from 400 to 800MH/s... but cgminer says I'm getting 4.6 GH/s. I've tried multiple pools, and the speed discrepancy appears to be the same for every pool.
