very true, i have ordered some voltage regulators, so i plan to change 1 out on the very dead ant ... whats the worst that could happen  I've been digging in my old posts looking for unresolved issues and AntMiner U1 hacking issues and found this ... and to answer your question... a dead ASIC from soldering a ' 103 ' smd for R2 and finding one end also went to that cap close to those pads shorting part of the power so it's not even having any sign of life is the ' worst ' thing.. Yea, I admit I should have checked and solder wicked up the excess prior to plugging it in. The red LED did flash 5 or so before nothing... total nothing.. I'm looking in to getting a fresh ant and doing a part by part swap one day to see if it's fixable. In the mean time my ( averaged ) hashing 25 GHash/sec only during daylight hours is down to point tripple zero 3 to 7 per day on BTC so it's gonna take a while.... back to doing BTC faucets and dumping the proceeds on to either Cryptsy or Peerbet to have them deal with the ' dust ' aspect. |

The password error is now common place. Basicaly, it checks for the ' common ' 1 number, 2 letters ( small and caps ) so just make sure Bitcoin-QT.conf and your BAT file have the same password with at least 1 number and at least 2 upppercase and lower case letters. It may give that error if you change to this example password as it may be ' too short ' as far as Bitcoin-QT is concerned as over 8 character passwords are more secure
EXAMPLE: -p 1Ab
I strongly advise using at least 1 of the characters from the number keys EXCEPT these 4 ' # & * % ' as they are considered special case characters in WINDOWS and may be misenterpreted.

I just installed the newer version of bfgminer and everything seems to be working fine. I'm using a 2A usb powered hub, so that's my problem. i will have to wait until i can order the eyeboot 49 port hub with 40A, then I will order more NF2s.
I am doing a little testing now with everything working as it should be, but chip a on one of the NF2s doesn't seem to be getting read. It just says 0.0 / 0.0 / 0.0 h/s, and when I hit the down arrow to go to chip b, it reads as normal. Does anyone know why it might not be reading something on that first chip? Is it something wrong with the NF2 itself or what? thanks
I did read the other responses prior to this quote, in the meantime, If you feel brave, I have some options that may point out the issue and eliminate power as an issue. I had to do some similar troubbleshooting on my own equipment and antminers/erupters/etc that turned out to be the hub and power as issues so it's similar. If you can find a HDD to fan type connector ( cheap 12V powered from HDD passthrough fans ) and make a jumper to your hub ( cut off at the fan for length of cable and doubble check which is power, which is ground ). MOST ( not all ) power connections at USB Hubs have center pin positive. I took one of them and desoldered the power connection and found that it's outer power on mine. I also found a ' flake ' of solder AT the pins of the USB Hub IC ( 1 to 7 hub IC after a 1 to 4 hub IC ) keeping the D+ and D- on one port shorted to each other ( no detect anything on that plug until it was cleaned, lucked out it didn't kill the IC or that port ). I CUT the 5V line for the USB cable ON the board ( and long enough to undo if needed ) so I wouldn't power the PC from the hub. I did a similar mod for a 7 port hub but with a wireless router power adapter as it was rated at 5V @ 2.5A DC. Some other posts recomend signal diodes for the 5V USB cable to the modded hubs to prevent power going back in to the PC or causing issues. If you keep all grounds as ground ( no floating voltages, and ground from everything eventually hits the pc power supply ground ) everything should be ok. I also checked the hubs' caps ( yes, there are 4 capacitors in one of my hubs ) and replaced them all for higher rating ( moved to 16V 2200 Uf from the 6v 1000 Uf ones ) and the other hub didn't have any on the power line except the ones at the Hub IC ( to clean power ). Hope this helps someone out there  and good luck mining! |

with me looking in IF anyone has ported the CGMiner HEX patch to BFGMiner ( and not finding it ) I've found your unanswered question.
Answer: the A2 is cheaper in the short term ( gets you started mining at at least 18GHash/sec, I've maxed at 22GHash/sec with out hardware modding it... yet.... cooling is an issue ). If you have the cash/BTC definitly doubble the hashing power with the most hashing you can get with what coin you can afford to invest in hardware and power cost per month.

dig around in old PCs for the 5v fan adapter * dual ended cable with 5v fan off of the 5v line * I cut it half way to the fan and soldered it to where the power in to a 10 port hub goes so it's getting 5v from a HDD connector and I have 4 Erupters all nicely powered and mining ( and 2 of my 3 ants on different USB ports ). Keep it up and you might be able to do what I did.... buy 2 ants from group buys ( including shipping ) with mined coin! I also kept hitting some of the BTC/LTC faucets to up my monthly coins and used places like Cryptsy ( an exchange ) or peerbet ( gambling site ) to convert the ' dust ' to slightly larger lumps to go to my wallets ( yes, plural, hard to steal all my coins from 4 different wallet.dat files with at least 2 online! )  |

with ' no joy ' at this point I'd swap over to a PC and rebuild a fresh download of BFG and include KNC, disable OpenCL enable CPU. The last 2 are just to make sure you have the full pack downloaded and all dependencies. once built, only 1 in a USB port ( part of troubble shooting is try 1 device at a time due to power restrictions ) DIRECTLY on the PC. A front pannel connector directly to the motherboard is a wonderful thing! IF it does work ( ' sudo BFG etc, etc ' ) remove it while it's running and swap to the same USB port the 2nd Nano. BFG should try and re-enable ( done this with ANTMiners and Erupters to find dead/underpowerered USB ports ). Assuming this works, it's a matter of doing it all again on the Pi ( with out the CPU enabled ) and trying there. I've had to open USB hubs and bypass Zeners, regulators and a few other ' power tricks ' that would limit the 5V line to 500 mA per port. I don't have your hub so no clue what/if it does for voltage regulation that can also cause this issue.
One ' trick ' I have in my list of things to do with powered hubs is find the 5V line from the pc ( or Pi in your case ) and cut it to prevent power issues and to ensure the powered hub IS getting power from the brick. I can never say this enough, share the ground plane, separate power for the miners so power isn't getting used for more than the miners and you can tell what bricks overheat.
May the force be with you.

With the pics, i admit my other statement is completly WRONG. The ' other ' multipliers I could find ( some on eBay, the actual ICs on TI.com ) were mostly 2x with an option of what speed and thus a colour difference in slots IF it had 4 slots. Just looking at the pic of the actual card, there are more pins on that one multiplyer IC ( over 40ish in quad flat pack ) and it definitly looks like it actually talks to each slot individually. I'd love to find out the hard coded limit ( if any ) for GPUs with that kind of thing.

I ' knew a guy ' that was starting that kind of business ( delivery of items to homes after normal store hours ) and he ran in to a few issues. The list I gave is a good one as he tryed to order ( against my advice ) for his ' regulars ' not knowing if they would suddenly stop ( which some did ) and ended up just barely breaking even after all the local taxes, paperwork in general, gas costs, etc. The business was similar to ' dial a bottle ' but non-alcoholic items ie doritos, subs, pizzas. If you just looked at the income, it was well over 1k ( canadian ) per month, but the taxes, expenses and buying ahead of orders that didn't come in killed his business. Keep this kind of thing in mind and make it drive you FORWARD to make it a business you can pass on to your children at a point where they don't even have to lift a finger for it to have the coin roll in.

Like the idea, see a few hurdles for you to watch out for
1) don't store perishables on ' company ' site - you can get alot of flack for ' sellinng ' limpy carrots
2) dry goods ( cans especially ) also need attention - I was in a derivitive of Amway and there was alot of flack on a dented can
3) cities that you can get at least 3 delivery people in to do the deliveries - people tend to sleep, eat, etc and not run 24/7
4) connections with wholesalers - cheaper you can get before it hits a ' store shelve ' not only more profit, more likely to be fresh
There were more items in the ' off the top of my head ' list, cut it down to the top 4 so you wouldn't think I was against you, instead trying to encourage you with what to overcome ( and you can ). Good luck with it.

I've already got a @ 10A solar charge controller ( don't ask, it was cheap on eBay and works ) so... Where can i get 6V @  ma Solar Cells for BTC?? The 6V batteries I can get ( cheap/used from a motorcycle friend ) and currently mining away to get a Pi with BTC which leaves the solar cells ( rain enclosure, mounts, brackets, more wires, solder, connetion type stuff and more miners ) If the Alt coin comunity swapped to this kind of setup, we could bypass the ' http://www.youtube.com/watch?v=tO5sxLapAts underwear gnome " issue and just be 1) hook up miners 3) profit!!!! admited bad posting of a youtube clip, but it's relavent |

I think I need to do pin shorting but can someone confirm ? I cannot see this mobo in the list. That isn't an all inclusive list. Try the A1 B17 jumper and see if it detects. It's a quick troubleshooting step to find out if that is your issue. yes and no on the ' quick ' part, there are a few posts later in there that reqired 1 slot empty on a board that had 7 slots and a similar ( not from the same manufacturer ) where 1 slot needed a jumper, the rest didn't. It's a long read and could be worth it for alt coin mining as GPUs are still cheaper to get ( for me at least, and only the older OpenCL ones ) than dual miners or the new asic script miners. |

Hi guys just wondering if someone can advise me, i withdrew part of a bitcoin to my wallet for the first time, a few days ago,
and its up to 133 confirmed, its showing a balance, but no balance in the unconfirmed as 0.000btc, and in transactions the logo is grayed out,
am i doing something wrong to need so many confirmations.......thanks
1) back up your wallet.dat to a thumb drive and name it something simple and obvious like ' BTCWallet.dat.encripted ' 2) close and restart your wallet 3) you didn't say what OS or version of Bitcoin wallet you are using, download the latest version AFTER killing the current one you have ( but not the wallet.dat or block chain info ) and try that. |

I don't want to discourage you, just point out what little proffit I've recieved, I've recieved by mining one pool steady. The only way I've gotten anything to mine a 2nd pool is to have more hardware on a different pc do the mining OR a new terminal window and one for the GPUs, one for the ASICs. With how the S1 is, I really doubt you can start a 2nd instance of it from the console to have half of it mine one pool and the other half mine a second pool.
The only option I can see from here is get a 2nd S1 and set it to the other pool.

Hi, thanks for your help.
I already have a good idea of what I am doing, I have a couple of BE cubes and a couple of Antminer U1 rigs. Trying these thumbs to see what they're like.
Followed your helpful guide and built the provided cgminer version on my Pi no problem, however when I run the newly compiled cgminer it does detect the thumbs and shows them as active, but they do not hash and instead I periodically get timeouts from them:
[2014-03-16 22:29:31] DRB 1: Timing out unresponsive ASIC 0
I built the same version of cgminer from the git repo above on my Mac and it detects the thumbs, but not correctly, I get the same message as I was having before:
Drillbit detect (20:7) failed to initialise (incorrect device?)
Think I will just stick to the U1's and cubes for now until hopefully Bfgminer will be updated for proper support for these new thumbs.
I appreciate the input though, thanks.
I'm on Ubuntu on a dual Coppermine rig... and switched to BFGMiner to eliminate that kind of error then found out it's a power issue. I will have to assume you are using one powered hub. I've ' borrowed ' a wireless router's power brick for a steady 2.5A @ 5V and have also found out the power rails IN the hub won't let me have too much draw on either side of the 2nd hub ( 7 port hub, 3 ports from one end, 4th goes to the second IC letting the last 4 count as a different power rail too ). Point being, check your power as I get that kind of error ( don't have any drills to test it on, from what I read, they use more than an Ant ) when I reorder what i've got plugged in. Good luck. |

Would an Asicminer that mines at 2Gh/s running on a Rasberry PI be enough to make a decent amount? I'm quite new to this.
Depends on when the difficulty changes, currently I've got one rig with 3 Ants and 4 Block erupters that can at times get me 0.001 per 24 Hours ( estimate 0.01 payout every 11-15 days currently ) so more hashing power, more money. As I've bought 2 of the ants with what I earned in pools ( and a ton of ' dust ' from free BTC sites ) profit is relative. If you are looking to get 1 BTC in a year or less, you really need around the max a Pi can handle ( 120 miners and related powered hubs ). |

I've dealt with one of the guys associated with Cryptoware and he's in the UK. Only issues were at either my end or my wallet. They do BTC, PayPal or credit card and no, no commission for me, just a happy customer passing them along. www.cryptoware.co.ukYou may want to get a powered USB hub and start with a minimum of 3 AntMiner U2s the U1 seems to be out of stock from the manufacturer. |

he said no Linux and no Pi, must be Winblows... So, if you dig around you can find one of the older tablets that run Windows CE and has USB, plug in a USB/Ethernet adapter, cross your fingers the drivers will work in Windows CE and use that. Those old palm clones came with some weird options and docks so it's possible that you can find one of those that will work and use as much power as 2 overclocked AntMiners. Good luck. |

you need to tell it to use a different clock speed, the default is not overclocked and can be lower than the 1.6GHash/sec when you start BFGMiner bfgminer -S antminer:all -S erupter:all --set-device antminer:clock=x0981
the -S antminer:all just tells it to look for them and use all it sees, same with the erupter ( if you ever get more, sometimes others show as them too ) the --set-device antminer:clock=x0981 tells it what speed to set the AntMiner U1 ( or U2 if you ever get one ) and this is the highest setting with out soldering on resistors ( and stable ) getting you close to 2.0 GHash/sec. You will want to invest in a powered USB hub that can deliver more than 500 mA @ 5V per USB connection. Most motherboard connections can actually do close to 2 Amps ( not all can, check the fine print in your motherboard manual ) when you use a front pannel connector TO the connector on the motherboards. It is a keyed 10 pin ( actually 9, one pin missing on purpose to orient it ) and I've used it for connecting 1 Ant and 1 Erupter with no power issues. Good luck. |

Not a problem and basicaly yeppers. You may want to do some digging in the different threads ( under hardware or search for S1 overclock ) and look in to the details on the overclocking/overvoltage. I've got AntMiner U1s so for me it's a matter of powered USB hubs ( protective diodes, Zeners, etc ) and possibly really fine soldering in of some 10k SMD 0603 resistors ( last is the size of the tiny things 0804 are barely doable with a fine tip soldering iron, 0603 is hot air and watch you don't literaly blow it off )
You may want to look in to removing the ' extra ' mining settings while you are at it. I've got BFGMiner on a pc set up to mine at 2 different locations and there have been times that one pool seems unreachable and it won't go back to it for a few hours manually trying to get it back there. In your case, it may go back to mining for ' the other guy ' which would do you no good.
Good to hear it's working and good luck with mining.
