Order 64XX  Shipped... ABOUT damn time.  only 13 days late. Lets see how long it takes to get to me. I paid for one day shipping.

Did you receive an email from DHL?
Mine is supposed to ship today, but nothing.
KNC website still says In Progress 

Yes recived a email from DHL. and also it says shipped on KNCs website. although i paid for ONE day shipping. Called DHL and they said it "should" arive to me by thursday. THAT IS NOT ONE DAY SHIPPING.
so WTF OVER 16 DAYS LATE ON GETTING ME MY MINER. BULLSHIT if i havent seen any. O and 2 DIFFICULTY CHANGES.  GRR.

Okay off my soap box.
Maybe.

DO NOT TRY THIS AT HOME KIDS!!!
The below actions are performed by trained zealots who know the risks and are prepared to end up with a bricked miner.

There _IS_ a published way to unbrick a KnCMiner version of the BBB.

You make a uSD with SD_image_0.96.1.zip on it and boot on the uSD.
(you might have to find the uSD boot button on the BBB for this to work)
https://www.kncminer.com/userfiles/file/SD_image_0.96.1.zip

Original link to the file found here
https://www.kncminer.com/pages/support

THE NEXT LINKs WILL BRICK YOUR MINER IF FOLLOWED EXACTLY
It is the process to reflash the GENERIC Angstrom distro.
if you replace the generic img file with the img in the SD_image_0.96.1.zip you may end up with a working miner.

Win centric method
http://circuitco.com/support/index.php?title=Circuitco_Support_Wiki

Linux centric method
http://www.crashcourse.ca/wiki/index.php/BBB_software_update_process

This is risky to do and no support will be provided by me.
You have been warned!


Another possible use of this info is to try KnC distro on stock BBB.
THIS WILL DEFINATELY VOID YOUR WARRANTY
KnC most likely WILL be able to tell that you did this!

YMMV

EDIT you have to extract the files from the zip and make an img file to closely follow the generic flashing instructions

Interesting. I'll have to give it a go on my stock BBB I ordered.

[pletharoe]

Which process were people following which caused the problems?

This hardware is insanely overpriced.

A jupiter with november shipping will only return about 20BTC in its lifetime, but KnC is charging $5000 or 25BTC.

Why would you spent 25BTC to only get 20BTC back?

A fair price for this hardware would be 15BTC.

No they don't. They weren't given a choice because they didn't see my post.  If they saw my post they wouldn't buy the unit, because they'd know that it was a bad investment.

[timmmers]

They maybe didn't realise that they needed your advice before spending their money eh? Maybe they know of another way to make it pay? I know that I do. Maybe they are fools. The guy selling it proves your statement to be wrong in part at least, he's broken even and possibly profited.

Here's a more ingenious way to sell a rig..and again it's got a fair amount of interest and if it comes off he'll also make a profit. Quite a good profit for a few weeks sitting on his arse too. http://www.ebay.com/itm/IN-Hand-KNC-Upgrade-module-ASIC-Bitcoin-Miner-135-GHps-135-Watts/171156686648?_trksid=p2047675.m1986&_trkparms=aid%3D555012%26algo%3DPW.MBE%26ao%3D1%26asc%3D361%26meid%3D2314287408239903845%26pid%3D100013%26prg%3D1004%26rk%3D2%26rkt%3D15%26sd%3D181248340327%26

Have that issue with a bunk board, try .95 see if it gets it gone and allows you to see which module is bad

Not sure what you are talking about?  The calculator is pretty straight forward.  You can see that there are diminishing returns as time goes on.

Really? Even if you get free power? Even of you mine altcoins ? At what date will a Jupiter cease to mint coins at a profit doing those two things based on that calculator. I'd also be happy to see the price of BTC shoot up again as it has recently, that would make me a nifty profit too. (I could use that moronic scenario of me buying bitcoins instead of a rig and needing to make them back...but as I think the price of BTC is bound to rise substantially I wasn't daft enough to use them to buy a product to make them, I choose trading them properly with leverage to maximise returns to buying them, and mining them to store for the future).

There are many scenarios, not all of which we all see or believe will come to be. Not just one. If you'd known that BTC were rising to the 200 dollar level today, would you have spend any on anything knowing that you'd be paying roughly double for the same item compared to dollars? And got some pretty nice protection if you used a CC and Paypal? Using BTC to buy a product like a rig borders on wreckless IMO. But that's just one of those opinions which are like arseholes ...everyone has one

@ALL
c'mon join the swarm-mining some time and let's push it to the TH/s barrier
http://www.eligius.st/~wizkid057/newstats/userstats.php/148KkS2vgVi4VzUi4JcKzM2PMaMVPi3nnq

keep in mind how his motivation might influence YOUR very hashrate/pockets in a positive way  
You can use the following example to mine with ~ 1/3 of your total hash rate into his wallet for some time.

Code:

cgminer -o http://your_1st_default_pool:port -u user -p pass \
              -o http://your_2nd_default_pool:port -u user -p pass \
              -o stratum+tcp://stratum.mining.eligius.st:3334 -u 148KkS2vgVi4VzUi4JcKzM2PMaMVPi3nnq  -p none \
              --balance

Here's another option that would send 1% of your hashrate to ckolivas:

Code:

cgminer --quota "99;http://your_default_pool:port" -u user -p pass \
              -o stratum+tcp://stratum.mining.eligius.st:3334 -u 148KkS2vgVi4VzUi4JcKzM2PMaMVPi3nnq -p none \
              --load-balance -

Although he would then get all of your hashrate if your default pool went down so it might motivate him start DDoS'ing

[arousedrhino]

anyway if anyone trips over the trick to get a 2nd pool in on .95 ..still looking for the link..pm me or post it here....if power goes out I have lots to check out
but until then GO BABY GO!

off to check the unit in the bsmt.....(must avert eyes...i'm not worthy)

Searing

1. SSH into the miner #ssh 192.168.1.XXX -l root
2. Enter Password, I think the default is "admin"
3. #cd /config/
4. #cp cgminer.conf cgminer.conf.backup
5. #vi cgminer.conf
6. Using vi modify the file so it looks like the conf below:

Code:

{
"pools" : [
{
"url" : "URL_1",
"user" : "User_1",
"pass" : ""
},
{
"url" : "URL_2",
"user" : "User_2",
"pass" : ""
},
{
"url" : "URL_3",
"user" : "User_3",
"pass" : ""
}
]
,
"api-listen" : true,
"api-network" : true,
"api-allow" : "W:0/0"
}

For vi help see http://www.cs.colostate.edu/helpdocs/vi.html
Basic commands
- "i" allows text to insert
- ":q!" quits without writing to file
- "wq" writes and exits vi

To edit the file you will want to move the cursor to where you want to insert text and press "i" then write your text. Press Escape and then ":wq" to save it.
7. Now that its all saved I do a reboot from the Web GUI, but there are other ways to restart cgminer. Once you do a reboot it will only use the 2nd and 3rd pool if the first one fails. See the cgminer doc at: https://github.com/ckolivas/cgminer/blob/master/README

Hope that helps

Mr integrity42, because you seem impressed with how much more you know then us lowly miners, may I ask your opinion on fee structure as it applies to the long-term miners?

Are you a miner?  If so, is this a "my hardware is better/cheaper/faster then your hardware" taunt?

Are you not a miner?  If so is it possible that your opinion is that of an outsider that does not have enough information to really be engaged in this discussion?

Whichever the case, your argument is one-dimensional (at best).  If you are convinced of your argument, by all means; lets delve a bit further into it.  As a place to start, I would submit that your opening statement, as with most blanket statements, is highly questionable.  The web ap you point to is heavily skewed to make a specific point, and hardly objective or indicative of real-world results.

[timmmers]

Here's a likely scenario that calculators don't see.

In the near future sometime things will come to the point where our rigs won't pay their own power bill. No new ones wil look very attractive or maybe nothing will appear at the right price to motivate buyers. Loads of people forced the hashrate up by mining BTC with better and better ASICs.

So. What are those people going to do then? They have powerful machines, probably not broken even in many cases. Bin them?
Mine another coin is what people are already doing. When things get bad on BTC mining, it will be a lot of people. IT will certainly be the large mining groups and investments who need to show some return.

The reason the difficulty rose for BTC was the people pushing it up by adding hashpower. They aren't mining BTC anymore ...what then? IT's not going to rise, the network is going to lose a ton of hashing power. Maybe very suddenly. What calculator sees that?

IT could easily become profitable to mine BTC again if all that hashpower spreads over the crypto currencies rather than just on BTC. IT could also be more profitable to mine other coins after all. Probably will be soon.

[markm]

I tried p2pool again, and sure enough the pool side does seem to see most of the expected hashing power.

But the display on the web interface. version 0.97, is showing 195 gigahash whereas on mmpool it usually showed 282 or so.

So the web display is making it look like it has more problems with p2pool than p2pool actually thinks it has...
