Every time a block is mined, a certain amount of BTC (called the subsidy) is created out of thin air and given to the miner. The subsidy halves every four years and will reach 0 in about 130 years.

When can we anticipate the Linux version?

We are working hard on Linux version software. And hope to release it some time in next week.
We have a Linux version software now actually. It works in most case when do a single device mining. It has some issues on multiple device mining, especially on beaglebone black board. Because a issue in USB to serial driver, Only 5 devices can mine together on beaglebone black board. The good news is we have resolved this issue yesterday. We changed the communication API from COM to pure USB api. This change requires a cgminer upgrade and code merge. It takes time. The latest development progress: Today, we have confirmed that on beaglebone, more than 64 devices can mine overnight stably.

In summary, we will release a cgminer in next week. It is based on cgminer 3.7. Please stay in tune!

I have an issue where my dualminers stop hashing in the middle of the night, I leave them at work so by the time I get in the office to reset them I've already lost precious mining hours

http://imgur.com/HmfeMsd

it looks like it's still connected to my pool, but my miner's status page on wafflepool says 0.00kh/s and it's not accepting any new shares.

Im running it via batch file as the dualminer software gives me too many HW errors (10% or more)

There's no payment options available to your address. Please check the entered address and try again.
No shipping to the USA, eh?

It's either that, or you need to fix your online purchase process.

Very cool

I am running 37 with 0 issues. I had 38 but had to send 1 back RMA.
Happy soo far. As soon as they finish the RMA I will be buying more.

You mention Beaglebone Black but raspberry pi should work too, yes?

Hello,
 I am having some issues with a manhatten 28 USB port and these minors.  I will list my setup below.  Hopefully someone has a suggestion on fixing it.  Dualminer recognizes all of them,.  Everything runs fine when loading but then I get comm errors and it says failed to load dualminer on comm17.  It does this for all of them. I am connected to the pool as new blocks are found no mining happens.
Thank you

The Manhattan 28 USB port suck you need more power to run the miner i would say a minimum of 0.6A per port.

Message me if you have any problems

I ordered two to play around with and they arrived last week.  Getting a solid 70Kh/s on each.



While they are not crazy, red hot, they are warm and a fan drops the temps by a good twenty degrees.


Full speed, Powered hub, no cooling fan.
  



Same setup, with fan.




And the pics are of the "pretty" side.  I did the same measurements on the ASIC itself, and while it was a bit warmer, the differential was the same.

I like them.  Might have to get some more!   And I'll be using the fan.

@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.

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.

When you say you get a bit more out of them using this argument how much are you getting? 
Do you put the argument in the dualminer software argument line or are you using something else?


What do you run instead of the dualminer software?
It does seem buggy to say the least.


they have a warranty. but mine run fine and have been doing so ever since I stopped running the dualminer software.

I shouldn't say I'm not running the software it's not 100% accurate. I running the cgminer 3.1.1 that is modified and in the cgminer win 32bit folder that comes with the software. I also messed around with the  "--dualminer-pll ###" frequency modifier. 800 is pretty stable and 850 gives a little more but I don't want to push these little dudes to far just yet. Of course, I don't have a clue what I'm actually doing but 850 makes a teeny bit more khs and is still stable so...whatever.

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
