[GB] USB ASIC miner - closed and completed

[wonker]

Klar. Wird oft im HTPC-Bereich so gemacht, um die Drehzahl (und damit die Lautstärke) von Gehäuselüftern zu verringern.

Ich habe hier einen von Rasurbo 40x40x10mm und einen noname und beide laufen nicht an, wenn ich nur 5V anlege. (Der Rasurbo läuft bei 5V weiter, wenn er Starthilfe in Form von 12V anfangs und später 5V kriegt).

[klotzenhotz]

Das ist bei jedem Lüfter anders, aber es stimmt, dass manche bei 5V nicht gleich anlaufen. Dann besorg dir doch so eine einfache kleine Lüftersteuerung wie sie in Lian Li und Fractal Design Gehäusen auch standardmäßig oft eingebaut ist. Da hast nen Drehregler, der die Spannung regelt. Wenn nicht bei 5V, dann laufen sie aber meist schon bei wenig mehr an. Oder du hast anderweitig die Möglichkeit, 6V oder 7V draufzugeben. (Im PC kann man auch 7V abgreifen: http://www.pc-erfahrung.de/casemodding0/lfter-drossel.html)

Hmm stimmt schon, im HTPC laufen meine Lüfter momentan auch bei 9V. Weiß nicht, wie es bei weniger aussehen würde.

Was wäre, wenn man bei einzelnen Minern einen internen USB-Port und somit die Gehäusekühlung nutzt?

Ich will keine ganze Lüftersteuerung. Das Teil kommt an eine Sheevaplug im Schrank mit USB-HUB. Da greife ich einfach vom USB-HUB Strom ab und setz den Lüfter drauf. Vielleicht kann ein Kondensator helfen, aber bevor ich mir um sowas Gedanken mache hole ich doch einfach den Lüfter oben, der auch bei 4V läuft.

from FAQ

Q: Is this a virus?
A: Cgminer is being packaged with other trojan scripts and some antivirus
software is falsely accusing cgminer.exe as being the actual virus, rather
than whatever it is being packaged with. If you installed cgminer yourself,
then you do not have a virus on your computer. Complain to your antivirus
software company. They seem to be flagging even source code now from cgminer
as viruses, even though text source files can't do anything by themself.

Wenn du eh einen Rechner laufen hast macht Luftstrom vom Gehäuselüfter wohl am meisten Sinn

Kaspersky marks cgminer as a virus always as well.

I think they don't like Bitcoins...

Auch bei meiner Wenigkeit hat DHL etwas abgegeben.

Gentlemen, I'd like to introduce you the extraordinary sensation, theee Block Erupter USB:

   

Note: ICA0 is a Lancelot, ICA1-4 Block Erupters. Wrong doubled MHs display values for Block Erupters due to my test setup, have to play around with cgminer options to get them fixed.

Vielen Dank yxt!

For Raspberry Pi users, Mineforeman.com is working on the software MinePeon (http://mineforeman.com/2013/05/26/minepeon-beta-1-code-name-butterfly-bob-released/). Beta 1, out 2 days ago, would detect and use our USB Gizmos, but it's untested yet as they don't have any USB Asic Miner and are still waiting for it.

I had problems with this version, as I can't access the stats page. I already discussed this with them and they are trying to bypass the problem. Previous alpha versions don't have support to this kind of Gizmos.

I had the same problem, I can't acces the stats page.

First I had to set the correct date:

[minepeon@minepeon ~]$ date
Thu Jan  1 01:11:24 BST 1970

[minepeon@minepeon ~]$ sudo date --set="30 May 2013 17:07"
[sudo] password for minepeon:
Thu May 30 17:07:00 BST 2013

At least a had to create the file /opt/minepeon/var/rrd/hashrate.rrd

[minepeon@minepeon dev]$ touch /opt/minepeon/var/rrd/hashrate.rrd

Now I can access the stats page.

But, my Raspberry don't discover my USB Block Erupter. Any idea?

The cgminer screen shot  looks like you are getting 660mh/s for each usb - I thought they were 330mh/s each ?

[EDIT] what cgminer params is that!

CONGRATULATIONS! You are so lucky... My 2 USB Gizmos still are in transit between Germany and Portugal...

Vielen Dank an yxt an dieser Stelle auch von mir.
Wirklich ein super Service.

I'll try later, when arriving home.

Quote from MineForeman.com:

MineForeman.com They (the USB ASIC Miners) definitely won't work with the previous version (of MinePeon) and while they will work with the current version it is totally untested. As soon as I get some of these devices in my hand I will be testing and probably releasing a new version with optimisations.

It's just a display/calculation error in cgminer. Devide 660 MHs by 2 and this will be the accurate number: 330. To confirm, U is around 5 with diff 1. Everything within specs. Reason for this display error might be I've running the Block Erupters (one core) with a Lancelot (two cores), have to play around a bit later to get the display error fixed. However, just wanted to show they arrived and hashing.

ct1aic, your little Gizmos will find their way as well, just one or two or three nights more to sleep.

I think it will be a week-end without sleeping... 

I will receive them next week, for sure.

And meanwhile...

I do like the new feature in my own forum signature, next to the link to my mining pool: (Forum warning: Possible phishing link!)

I've posted a short desciption to get them hashing...:

@Milquetoast
thx  

mineforeman is working on an update which will make these USB sticks plug & play, but until then, here's how I got minepeon beta 1 working with them now. *There may be a better way, this is just how I did it.

At the command line:
1. type (or copy/paste)

Code:

sudo nano /usr/lib/systemd/system/bfgminer.service

Now you're looking at a simple text editor
2. use the down arrow to find the line that starts with "ExecStart=" This is the command that will start bfgminer
3. on that line, use the right arrow to find "bfgminer -S auto"
4. change "-S auto" to "-S /dev/ttyUSB0" for a single miner, or "-S /dev/ttyUSB0 -S /dev/ttyUSB1" etc for multiple sticks
5. press ctrl+x to exit. nano will ask if you want to save your changes, press y.
6. type

Code:

sudo systemctl stop cgminer.service

(Stops cgminer)
7. type

Code:

sudo systemctl disable cgminer.service

(Stops cgminer from starting at boot)
8. type

Code:

sudo systemctl enable bfgminer.service

(Makes bfgminer start at boot)
9. type

Code:

sudo systemctl start bfgminer.service

(Starts bfgminer) You should now be mining, use the next steps to check
10. type

Code:

sudo screen -r

to display the miner's console interface, check to make sure it's mining
11. hold ctrl and tap a then d to exit back to the prompt without killing bfgminer

If you have any trouble, feel free to PM me. I'll provide as much help as I'm able.
