[ANN] Introduction to DualMiner USB (could mine both BTC and LTC)

[ManeBjorn]

That is cool  I will have to think about that before I do it.
Are these firmware upgrade-able as well for future improvements based on newer firmware?

Hi dualminer_3 is there going to be any firmware update for these to get a bit more performance out of them??
They run great but there seems to be room for improvement in the firmware.

@minorminer,
We will create a open source project on github for our software. Pi should work. We haven't test pi board yet. As long as we have solid result on beaglebone black. We will start work on pi if there are issues on it.

Change the command line param --dualminer-pll will give you little more hash. In ltc only mode, the default value is 800M. Change it to 850 or 900 will increase the performance. However, only some chips can work on 900Mhz. This variety is mainly because the manufacturing process.

NOTE: change this parameter to higher value may cause high temp and damage the device. This kind of damage is NOT cover by warranty

The firmware on the device is not upgradable. We don't need upgrade it actually. The firmware just convert USB to serial. Start from next version, our Windows GUI app will be upgradable. About PC Linux or ARM linux, since we will open the source code, users can upgrade to new version source code. To do a Linux upgrade, the user need have some experience on Linux.

Dualminer, I notice that on the op of this topic you mention that you can pay via btc. Why have you stopped that and do you have plans to restart it?

[poopypants]

When will the github repository go live?

[ManeBjorn]

Are you also opening it up a bit so other mining software like BFGMiner and MultiMiner can run these?
I am really liking my DualMiner it is just a pain to run separate mining software programs for them.

Yes, BFGMiner and MultiMiner can run dualminer devices if the code merged into them.

Excellent!
I think nwools and LukeJr are working on it now.  I hope it will not be long.
Thanks for answering my questions I really appreciate it.

Group buy here:

It's closing very soon (today). If you want em, give demonmaestro a pm and let him know.

[poopypants]

zellkoss: There is plenty of info in the thread on feedback, but my personal feedback is as follows.

Everything from the dualminer.com website has been professional, they ship fast and have great communication.  The dualminers work as advertised and are very easy to setup, windows machine is currently the only software supported but as you read above dualminer_3 is working on a linux version.  I can only speak for scrypt mining only, since I have not attempted double digging.  The units run cool mining scrypt.  If you want to run alot of dualminers it is required that you get a good powered usb hub, I am running 8 on a 3.5amp rosewell 10 port usb hub with no issues.  Some suggest a minimum of 5amps usb hub inorder to run 10.  There is a dipstick on the unit so make sure the position is correct, switch flipped up is scrypt only, switch down is dual mining.  Ask away any questions and I will try to help.

[zellkoss]

@akeetlebeetle  Thank you but i'm not from US.


@poopypants Thank you for your feedback ans the technical spec of the USB HUB. I will look the previous post for the others.

He doesn't have anything better to do so he just attacks various threads with Tabloid type information. Best to use the Ignore function.

Is this good or bad?
It's a lot of info but I am not sure what to make of it.

I think he believe's he's the crypto world's Robin Hood...  Nothing better to do than show people how he knows how to use Google.

[ManeBjorn]

 Ah ok I did not know that.

[ManeBjorn]

LOL that is a good one.
If he is a crypto Robin Hood he should send his spoils to me.  I'm poor and disabled and struggling to get by.  Not a joke. 

On topic though the DualMiner people have been great both sales and customer service wise.  They keep in excellent communication and are actively developing their software with community input.
I am very happy with them so far.

By the way did no param string help you out at all with your DualMiner?

Testing it out now, appears to be a little quicker.   

[ManeBjorn]

Good deal.

UPS is delivering these today. Will run these from a batch file from the cgminer bundled with the dualminer install unless I run into problems. Don't need a GUI sitting on top.
