Worked like a charm after two reboots.

Thank you for your help.

My logs are empty, but I will check them again later when I am on a regular computer.

Logically speaking, yes it should, but it is not firing up in Minera. I have tried multiple times and run a ps -ef | grep bfgminer in the command line and nothing shows. It does temporarily fire up, but it crashes or simply quits after processing a few transactions. The Minera dashboard doesn't even detect bfgminer running at all when using the command line interface to get mining again.


I hope this helps.

I can fire up BFGminer using the command line, using:
nohup bfgminer -all the necessary flags- &

All of my Antminers fire up and begin mining just fine.

I tried that command and still no dice; this includes rebooting the Pi. I take it we will have a 0.3.9 in the very near future?


How does one revert to an older image for the time being?

BFGminer crashes in 0.3.8 and my Antminers are not being detect by any of the other miners available via Minera. My Gridseed gets detected in cgminer-dmaxl-zeus, but that's it 

I actually have those commands saved in the rc.local text box in the web based interface, no dice. The issue could be due to the fact that I run BFGminer for my Antminers and CFGminer-DMAXL-ZEUS for my Gridseed.

Once I get my Gawminer, I will be using BFGminer for it, hopefully.

Will there ever be multi-device support???


I have a Gridseed Orb, 4 Antminer U2s, and a Gawminer Fury and would love to have all of them displayed on the dashboard. I run the Gridseed in dual mode, which is nearly impossible to do in the web interface, and the Gawminer can only run in scrypt mode. It would be great if the dash can display each of the devices independently, because I will be mining a multipool for the miners doing scrypt and a Bitcoin pool for miners performing SHA256. I know this is a tall order, but believe it could be done.

Also, I had setup a quick instruction guide to setup dual mode for the Gridseed Orbs/Mini/5-chip, if this can be of any help to be able to enable dual mode via the web interface:

Personally, I really like the interface of Minera and the app support to check on my miners remotely via the iOS app that is compatible with it. I think Minera is probably the best that I have seen yet for a web-based interface, especially that the interface can easily switch between desktop and mobile browsers. I hope you (or your development team) continues to do the good work that you do. It is really a blessing to have such an easy to use interface, even for someone like me who is comfortable in a Linux shell.

I have a BTC-E and Cryptsy account. I just can't find good instructions on how to automatically convert altcoins to btc.

Hi everyone,

I am not sure where I should ask this, but what is the easiest way to exchange alternate coins like litecoin and dogecoin for Bitcoin?

I have done a lot of Googling and lurking this forum, but I can't seem to find anything that is easy. Any help provided will be greatly appreciated.

In all seriousness, I agree with these other posters. I have a Raspberry Pi  as a controller and run both Antminer U2s and a Gridseed Orb (aka Mini or 5 Chip), and needless to say there will be a return on investment, but it will be a year or so. I would recommend Antminer U2 or preferably a Gridseed Orb/Mini/5 Chip, because the Gridseed can do either Scrypt or SHA256 or both types of crypto currencies. Other than that. If you want an expensive, but more power friendly dual miner, then get a DualMiner. The DualMiner does 70kh/s for Scrypt or in dual mode 500Mh/s SHA256 & 40kh/s Scrypt.

You can find the above devices on eBay easily for under $25. If you want to make serious coin, then expect to shell out thousands of dollars or of your local currency to make it big, but remember your ROI will take longer as time goes on.

P.S. - I don't intend to get rich, just want a fun hobby and make some "coin" 

Howdy,

After a lot of cursing and hours of frustration, I have successfully got dual mining to work in Minera v0.3.6. The problem with getting Gridseed Orb / Mini / 5 Chip in dual mode was the bloody software (cgminer-dmaxl-zeus) would accidentally take away my Antminers from BFGMiner, a very irritating problem and one that has not been resolved until now (I have spent countless hours Googling and only finding others with similar issues, but no resolution). Well look no further now, dear friends.

Step 1 - Get Minera v 0.3.6 or later.
Step 2 - Use BFGMiner to setup your Antminers (or non-Gridseed / non-Zeus miners).
Step 3 - Use SSH to log into the Linux shell and once in the command prompt, type in "lsusb" without the quotes. You should get results similar to that of below:

user@minera ~ $lsusb
Bus 001 Device 002: ID 0424:9514 Standard Microsystems Corp.
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 001 Device 009: ID 10c4:ea60 Cygnal Integrated Products, Inc. CP210x UART Bridge / myAVR mySmartUSB light
Bus 001 Device 010: ID 10c4:ea60 Cygnal Integrated Products, Inc. CP210x UART Bridge / myAVR mySmartUSB light
Bus 001 Device 003: ID 0424:ec00 Standard Microsystems Corp.
Bus 001 Device 005: ID 0483:5740 SGS Thomson Microelectronics
Bus 001 Device 006: ID 1a40:0101 Terminus Technology Inc. 4-Port HUB
Bus 001 Device 007: ID 10c4:ea60 Cygnal Integrated Products, Inc. CP210x UART Bridge / myAVR mySmartUSB light
Bus 001 Device 008: ID 1a40:0101 Terminus Technology Inc. 4-Port HUB

Look for the ID that contains SGS Thomson Microelectronics (as you can tell I have 3 Antminers, which use Cygnal, so it was easy to pick apart the correct device).

Step 4 - type in "nano /etc/rc.local" without the quotes and press enter.
Step 5 - add the two lines below before the "exit 0" without the quotes, but make sure you modify them for your setup or it will not work:

su - minera -c "screen -dmS SHA256 sudo /var/www/minera/minera-bin/cgminer-dmaxl-zeus --usb 001:005 --sha256 -o stratum+tcp://stratum.bitcoins.com:3333 -u username -p password"

su - minera -c "screen -dmS SCRYPT sudo /var/www/minera/minera-bin/cgminer-dmaxl-zeus --usb 001:005 --scrypt -o stratum+tcp://stratum.scryptcoins.com:3333 -u username -p password"

Step 6 - reboot and enjoy.

P.S. - Sometimes BFGMiner can be finicky with the DMAX and cause your Antminers not to work, just log into your shell and type in:
screen -dmS BFGMINER bfgminer -o stratum+tcp://stratum.bitcoins.com:3333 -u username -p password -S antminer:all --set-device antminer:clock=x0981

It should fire them up for mining Bitcoins.

I just tried to go dual mode with the Gridseed using the cgminer-dmaxl-zeus, while having the Antminers use BFGMiner. Everything got borked 

I just went back to my original configuration of BFG for Ants in Minera (the web interface only detects the ants for some reason) and BFG via rc.local as described earlier.

I also tried just CPUminer, which set everything to 800Mhz and only the Gridseed worked for kh/s in BTC and regular CGminer, which only detected the Ants. I am hoping that I didn't fry anything, but good grief, you think this would have been easier to deal with. Hopefully Minera will eventually be able to handle multiple devices via the web interface.

As for the CGMiner-dmaxl-zeus, it seemed to grab the Ants and not the Gridseed, or it would go vice versa, but not both. Any advice?

Well so far I am liking. I literally got my first one today. I plan on using my Gridseed for mining LTC for now, but the cool part is that you can also mine SH256 (Bitcoin) by itself or both LTC & BTC. So far I have chosen to only go the Scrypt only route for the time being to mine more profitable crypto-currency (LTC/Doge) and then convert those coins to BTC since BTC is more useful - thank you NewEgg, et al for your support!

Right now I am mining around 350kh/s at stock (600Mhz). From my research, most people push this thing around 800Mhz to 850Mhz for Scrypt, 750Mhz to 800Mhz Dual Mode, 600Mhz to 750Mhz SHA256 only. Most posts lean to 750 Mhz or stock for Dual Mode due to hardware errors generated at higher frequencies. Also, remember the higher the frequency, the more power this thing will need.

For mining BTC, I am running 3 Antminers and planning on getting a forth (or fifth - maybe?) once I get my new powered USB hub 

I would recommend the Gridseed Orb, if you can snag them at a good price. I got mine for less than $25 new on eBay. Supposedly the seller I used does a pre-test to ensure they work before shipping them. I just look at as a flexible miner, if LTC/Doge doesn't work out, yay it can still mine BTC; if BTC does not work out, yay Scrypt whatever is popular.

The only problem I have with the Gridseed Orb is that the 90mm fan is freaking loud. It's in my basement - thank God - and should have excellent cooling regardless of the fan. I seriously think the fan is louder than my dehumidifier's fan 

P.S. - I use Minera (latest version) and my Antminers are displayed on the dashboard and I run the Gridseed using the following entry in my /etc/rc.local file:

su miner -c "p bfgminer -o stratum+tcp://server.domain.com:3333 -u username -p password -S gridseed:all --set-device gridseed:clock=600 --failover-only --scrypt &"


Just use that string if you plan on using it as a Scrypt miner only. I tried running two instances of BFGMiner on the Gridseed for dual miner mode and it was a no go. Axiste is right, you should only CGMiner (DMAX version I believe, check with him though, because I could be wrong) for dual mode. Since I like BFGMiner - just a personal preference - I am sticking with it's either or of mining with the Gridseed; meaning I can only mine Scrypt (LTC/Doge) or SHA256 (BTC) only, not both.

Since LTC/Doge is more profitable, I would recommend Scrypt only mode for two reasons:
1. It only uses 7w (when overclocked beyond 600Mhz - 5w @ stock supposedly).
2. Scrypt is easier to mine and thus you get more payouts more often. You can exchange the Scrypt towards BTC at an exchange, which is what I am doing.

Note: You can use a pool that automatically converts Scrypt to BTC and switches to the more profitable currency over time, but I feel like I get paid less often by these pools. It's up to you how easy you want to convert to BTC and what your are willing to sacrifice.

Axiste, thanks for all of your help. I found your post dealing with Dual Mode here: https://bitcointalk.org/index.php?topic=780210.msg8812448#msg8812448

I just wanted to post the link for everyone else trying to find it. I decided to stick scrypt only for the time being. It's amazing that this thing can crush my high-end GPU 

Hi,

I just downloaded this nifty software and I cannot for the life of me, get my WiFi adapter (Ralink RT5370 chipset) working. I was able to get to launch the wicd-curses menu and follow the instructions to setup my WiFi adapter; however, it's not being detected. I know the adapter works, because I have literally just switched from Raspbian to Minera. Its been running maybe for 5 minutes. I would appreciate any help that can be provided.

Lastly, can you set one device for scrypt (e.g. Gridseed Orb) and others for Bitcoin (e.g. Antminer U2)? If so, how can you do this with Minera?




TL/DR: WiFi was not detected by wicd-curses and also want to know how to setup up Gridseed for scrypt and Antminer U2 for Bitcoin.

EDIT: forgot to use "sudo wicd-curses" - smh 

Wow that sucks that BFGMiner can't do both, I thought at least it would require two commands like CGMiner. I will checkout the thread that you speak of, I greatly appreciate the help 

I have been doing a lot of Googling and searching this, et al forums and literally cannot find any commands to do so. It's either just Scrypt or SHA256, not both, and threads that have asked the same didn't get crystal clear answers or devolved into arguments for or against dual mining.

I am trying to dual mine with BFGMiner using my Gridseed 5 chip orb that should be arriving any day now. I will be using my Raspberry Pi B+ as a miner controller, because it sips energy compared to my gaming rig. Yes I know it uses about 60w of power to dual mine, but energy prices where I live is very negligible (about 4.5 cents/kwh). I am running Raspbian (tried Minepeon, but unfortunately it's not completely working with Pi B+ yet), not sure if this would be of any help.

I appreciate any help that anyone can offer. I am looking forward to getting my Pi setup, so it is just simply plug and play (or pray for those as old as I am  )

Howdy All,

I am trying to find who is the best multipool mine that switches to the most profitable currency overtime and pays out in Bitcoins. So far I am Slush's pool and WeMineAll for mining pools, but I feel like I could be doing better. I have a Radeon R9 700 and Antminer U2, and a Gridseed 5 chip ASIC (arrives this week, hopefully). I know that mining kit is not the best, but I am putting the Antminer U2 and the Gridseed on a Raspberry Pi b+. Any advice or help, would be greatly appreciated, because I hate wasting my time and electricity.

Oddly enough:
https://freebitco.in/ and http://moonbit.co.in/ are both out pacing either of the mining pools I am part of in terms of payout  

Yeah, I am not expecting to become rich. Just make a few bucks off of a project over time. The beauty of my setup is that I can scale with either Gridseeds or Antminer U2s on the cheap over time. It's just a fun project that has more benefit than other hobbies that I have gotten into.

I am really enjoying playing around with virtual currency. I have like 5 wallets now, because I can't decide which one I like the most. So far I am trying to find a wallet that my wife and I can share, so we only have one wallet (that is not tied to servers, because I don't trust third parties storing my money that aren't back by insurance). I know it's not the most secure method, but my wife isn't that great with technology, especially when it comes to things like Bitcoin. I just want to make sure that she can access the money and exchange it for currency, if something should ever happen to me.
