Greetings!

 I've finally got the Antminer to run on my Raspberry Pi, but it keeps going zombie on CGMiner. The build that Bitmain offers doesn't have this issue on Windows; Is this version also available on Linux? My laptop will run them just fine, it's just bulky as all hell if I try to mine with them on my laptop, and wanted to avoid it if I can.

Same error. Can I import keys using something else? Does Bitcoin-Qt offer the ability to import keys using CMD? Or, is there a way I can paste them all into the console? I tried to add the importprivkey in front of each key, but I can't just drop them all into the console since it doesn't understand a line break.

Oh yeah, I do have to type Py before PyWallet to call it. I should have added that. Sorry for missing that in the original post. PyWallet is being called, since I can see the help text that automatically shows when you fail to type what it wants.

Good eye on the missing dash, but it's still spitting the same error message. Sad

I replaced the equal sign with a space, but it threw the same error message as before, mandatory option missing. Sad

Also, it's jackjack's fork, if that means anything at all.

How do I import private keys using PyWallet?

I am using Windows XP and PyWallet, though I don't remember which fork I am using. I am able to successfully dump the key I want to use, I am not sure how to import the key into the new wallet. PyWallet keeps telling me I am missing a critical command line option, but it refuses to tell me what I am missing. I tried to mirror some of the example command lines from the website, but they are either not exactly what I need (and being they are Linux doesn't help) or seems to be missing something.

PyWallet -importprivkey=LawlThisIsAnExampleWalletKeyUsedAsPadding --label=Main --datadir="C:\Documents and Settings\Owner\Application Data\Bitcoin"  --wallet=DonorWallet.dat

And before it gets suggested, yes I know how to import into the client, but I have about 700+ keys I need to work on, and I don't feel like doing each one manually. I hope you understand. Smiley If I can get the importprivkey command to work with PyWallet, I can handle the rest from there. Thanks in advance!

How do you take a variable voltage input and make it a fixed voltage output?
by
kodan50
on 10/01/2014, 08:37:24 UTC
For kicks and giggles, I wanted to purchase a raspberry pi, and run a miner on it; bitcoin, litecoin, whatever. I have some solar panels that I want to use to run the unit during the day.

 I want to build a circuit that can take any number of solar panels and output whatever fixed voltage I want. Is it possible to do? And, would the amperage change based on the voltage change?

 One final question: I've heard that electronic devices will only pull as much amperage as it needs to operate. My brain is having a hard time understanding why a 6V LED will burn out when a 6V battery is attached to it if it doesn't have a resistor. Do electronics only pull as much power as they need or is there some special device that limits the amperage going into it?

Well, that got it running in the latest version of CGMiner, so many thanks for that! So far, I haven't gotten any HW errors either, so maybe it was just a driver issue?

Now I just need 119 more ASICs to earn money. xD

Help with CGMiner and HW Read errors

Howdy! I finally got my Block Erupter and I want to get it working tip top shape. I keep having issues after issues. Maybe someone can help?

I am using CGMiner 3.1.1 because all the other versions of CGMiner keep spitting out error messages using the same CMD line, and I don't see what is wrong, since the help output in --help shows no capitalization error, and it looks like it is all there. If anyone knows how to get the newer versions working, I will love you forever!

For CGMiner, here is my CMD line in my batch file:
cgminer-nogpu.exe -o stratum.bitcoin.cz:3333 -u kodan50.worker1 -p ThisIsNotMyPassword --icarus-options 115200:1:1 --icarus-timing 3.0=100 -S //./COM6

I read that HW error under 1% is normal, but since I have an older version that just had HW numbers, how do I know what the percentage is of my errors? And, what can I do to keep the errors down?

After writing out this very long and though-out post just to have Bitcoin Talk just not post it, I am condensing the whole thing down.

*sigh*

Are there any native scrypt miners for Xbox? If not, how about a distribution of Linux that can make use of the GPU for Linux miners?

*EDIT Just to avoid confusion, I am referring to the good 'ol classic Xbox unit. Smiley

Re: How can I extract private keys from a compromised wallet.dat?

Have a look at jackjacks python wallet stuff. might be of help.

 Thank you for your suggestion. I've actually tried jackjack's PyWallet fork, along with a few other ones, and none of them would open the wallet. they didn't even output anything.

 I was successful in copying hex data from the compromised wallet and pasting it into a working stock wallet and I now have access to the Bitcoins that were inside of it. Thank you everyone for your replies!

 I appreciate the responses!

 I opened both the compromised and a working wallet in a hex editor. It looks like most of the data in the wallet is intact. I was sifting through the wallet and noticed a bunch of strings called Key, is this where the keys are? (It may seem like a silly question, but I don't want to just assume.) I tried to copy the hexadecimal values and import them as keys in both Bitcoin-Qt and Electrum, but neither saw them as valid keys. Are they compressed and need to be uncompressed before they can be used? Where do they start and where do they end? I extracted keys from working wallets to see if I can see a pattern, but the extracted keys aren't in hexadecimal, so they don't match. I thought I'd create a new wallet.dat and try to copy and paste the data between keys strings, but that didn't work, and somehow still shows the stock wallet's original receiving address. I feel like they are here, just waiting to be pulled out.

*Update

I might have posted a little too soon. I did some more copy pasting of the wallet and I think I found the private key. Waiting to test it, I just have to wait on Bitcoin-Qt...

[solved!] How can I extract private keys from a compromised wallet.dat?

I'm not sure how this happens, but the wallet.dat file will not load in any version of Bitcoin-Qt. It just comes up corrupt. I tried to run PyWallet on it to recover it, but it just exists and doesn't spit any output out. (I am familiar with how to use it, as I used to to extract keys from a good wallet. Of course, suggestions are welcome regardless!) The wallet didn't have much in it, but I'd still like to have them accounted for. The sad thing is, I backed up this specific wallet both when I first created it, and when I had to reload my computer. The original one just .. vanished. I have no Earthly idea how that just happens, but the only copy I have. Is it possible to extract the keys using a hex editor? It was created using BitCoin-Qt 0.8.1 and I think I upgraded the client to 0.8.5, but I don't remember now.

Bitcoin-Qt wallet issues
by
kodan50
on 10/12/2013, 00:27:37 UTC
 Greetings! I feel bad for creating an account just to ask for help instead of being able to assist others, but I wanted to make sure Bitcoin was really something I wanted to get into. Also, I do have a TL;DR version of this, but I have to write it all out before I can condense the issue. My apologies again.

 When I first started, I was reading up on Bitcoin and settled with using a client to manage the wallet instead of any of the online places. I went with Bitcoin-Qt. At the time, it was at V. 0.8.1, and I waited for it to download the blockchain. It generated my Bitcoin address, 1HVQFur9pMwRvf92t1AmYatsSRUCR3a2tm. I backed up the original Bitcoin wallet.dat I made to my external hard drive.

 Later on, I had to format my computer and reinstall. Well, I wanted Win7 on here and to finally retire XP as my main OS. I backed up my wallet.dat again (this time, it would have more transactions done on my main address) and installed the latest version of Bitcoin-Qt. I loaded my wallet backup and tried to run Bitcoin-Qt. It spit out the error "wallet.dat corrupt". My first thought was, if I made it for client v.0.8.1 and the new version was 0.8.5, maybe the issue was an update changed the wallet format. Hey, I have a backup of the original installer I used for bitcoin-Qt 0.8.1, so why not? I uninstalled the newer version, made sure the Bitcoin data was wiped from my APPDATA folder, and installed the older one.

 I got the same error. I tried both wallet.dat backups I had.

 So, I went online to see what the issue is, and I was having a hard time finding other people with the exact same issue. Either means I am very unlucky, or my Google-fu is not strong. Either way, I was lead to using PyWallet, meaning I had to install not only Python and a plethora of stuff to make it work, but I also needed a way to import those keys into Bitcoin-Qt.

 So I used it to dump the keys to a file, and I tried to import the keys into Bitcoin-Qt by using the console. The error I got back, when trying any combination of commands I found online, was error -32601 Method not found. I went to search for another client that can import the keys, and I found Electrum. It had the option to import private keys, but when I import any combination of keys for that Bitcoin address within the dump file, they don't come up with the same address, and instead, they come up with other addresses. What I did then was write a batch file that would extract every single key from the exported data, and I imported them all into Electrum. While the majority of the keys i tried failed to do anything, I was able to access two addresses that hashed out with those keys, which only accounted for about 30,000 satoshi's, as opposed to the 500,000 satoshis I have in the wallet. I guess my inability to really explain further means I need to read up more on the wallet format...

 Now, at this point, I am completely torn on how I can fix this issue! I just want to move all my bitcoins into a single address on a client that isn't going to break, and I don't even know if Bitcoin-Qt broke because of something I did. Also, for the sake of my sanity, what would be a good client that is less likely to break my wallet.dat? I mean, this is a bad way to ask because I could just be having a bad stretch of luck with an otherwise fantastic client, but .. I mean .. I just don't want this to ever happen again if I can avoid it.

DL;DR: I have a wallet.dat that won't load in any version of Bitcoin-Qt, how do I pull the keys out and use them in another client? What client would you recommend?
