with my new non-CE-conform self-build USB fan

Please be careful with that. Someone could hurted their finger. At least display some WARNING: HAZARDOUS MOVING PARTS signs nearby.

what? lol.  Im guessing youve never accidently touched one of those.  They dont even hurt.  Just scare the crap out of you.

with my new non-CE-conform self-build USB fan I could reduce the temps on the Block Erupter down to 36°C!

out of interest how did you measure the temp?

Anything done or said in this period wasnt me.
Many thanks to Cyrus for his help restoring access to my account.

infrared thermometer (pyrometer?   Cheesy ) (thermometer gun with a laserpointer to point at where you want to measure)

4-6 inch distance at all measurements and I am measuring all over that stick. highest temp with the fan next to it was around 37°C now (27°C in my living room / 32°C+ outside in the shadow)

and the devices just disapear from lsusb. I have to reboot at that point...

Also, is 9 eruptor ok on this hub?

I have quickly saw that an eruptor was taking .5A hence you could only plug 8.

thank you,

ok I kinda solved my problem.

I have removed 1 eruptor from my Anker hub. I have pluged the Anker hub in a USB2.0 port on my PC.

I have pluged eruptor #9 and #10 in a second USB hub.

With my 2 7970, I now have ~ 4.5 GH/s miner

thanks!

Can USB block erupters be plugged directly into the R Pi? I'm integrated in making one to run a solo USB, just for fun mostly.

No, not enough Amps on the USB Ports of the RPi.

Just an update about libusb in case anyone was wondering ...
https://bitcointalk.org/index.php?topic=28402.msg2817682#msg2817682

Basically I'm just verifying (trying to get others to check also) that it is indeed the version of libusb that's the problem.
Upgrading libusb may resolve it ... but once I have verified if it is the cause I'll go with including the latest libusb in the cgminer directory to ensure people are using a working version

However, using Arch instead of Raspbian should solve the problem anyway since the latest Arch has a working libusb that passes my test code:

 nice fan.  I got some on sale a while back.

  I am running 27 sticks with 3 anker hubs and 3 fans.

 I have a 9gh miner pulling 127watts  my gpu farm was 10gh and pulled 3400 watts!!

I see BTC as the super highway and alt coins as taxis and trucks needed to move transactions.

damn. Shipping: Currently, item can be shipped only within the U.S.  ;-)

Those are difficult to get in Europe, I recently bought an Enermax USB Fan (which is not produced anymore...  Embarrassed ) on amazon.co.uk for about 22 Pounds..
Actually its much cheaper to DIY with an old 120mm PC fan + USB cable

I'm still waiting for someone to publish a Android App that uses CGminer/BFGminer for ASICs, till then I'll just have to fiddle about with ARM Linux and see if I can get that going. I already got BFGminer compiled/installed. Just waiting for my OTG cable to show up.

I'd get a Rasberry Pi but I'd feel it's not worth the investment as I can't figure out a use for it outside of a mining host, I only want a host to use at night when I'm not on my PC.

So im still using cgminer version 3.1.1 (because it works) on my raspberry pi with a 7 port usb 2.0 hub. Only four erupters.

For this kind of setup, have any of the new cgminer versions helped out with the erupters going SICK?

I got 2 more today (I now have 3 AMUs) to ensure my previous testing was working ... hotplugged them into my USB3.0 hub plugged into my RPi ... 3 mining no problem.

The main problem is libusb that a lot of distros seem to have a bad version of.

The actual version of libusb on RPi Arch works - which is what I'm using when I hotplugged in the 2 new ones I got today.

Minepeon for RPi uses Arch ... also here's a simple howto I wrote to setup Arch for cgminer: http://www.kano-kun.net/?p=87

Use current git.

Temporary hack version of how to compile and link cgminer to 'the' good version of libusb on linux:

Here's mine up:




3 Dlink hubs - 5 erupters in each, 1 of them is daisy chained to another (raspberry pi only has 2 USB).

Running BFGMiner in Raspbian, with the Ardafruit LCD display, working perfectly.

Yeah, someone said the cooling wouldn't be enough, but the only thing that would be done better is a gap between the erupters - but tbh this way the air is channeled out anyway so i think its fine personally!

IF cooling is an issue you could easily update fan AND add heat sinks.
Your idea probably saves cost and electric usage of 1.1 fans per 18-21 units.
I'm also thinking a slight gap between the HUBS may be beneficial...
