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

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.

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!

Problem with Anker USB3 hub and cgminer 3.3.1 on linux-ck 3.10

I have the following msg:

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,

infrared thermometer (pyrometer?    ) (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)

out of interest how did you measure the temp?

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

thank you for your concern but luckily i did neither change the plastic-blades with steel-blades, nor does it go at 10.000 rpm only thing that could be hurt are insects trying to fly through it (actually i hope they do try.. )

Right click on your desktop. A window will open. In it, click "new". Choose "shortcut". A window will open in which you can enter one line - that's the target line. Enter or paste your data. Click "next" when you're done.

How do you create a desktop shortcut.
I know how to copy and paste and get my com numbers like below.
I just do not know how to make a command line on my computer from the example below


Thankyou.


STEP 5: Create a Desktop Shortcut.

To launch cgminer, create a shortcut with a target command line that looks like this:

C:\cgminer\cgminer-nogpu.exe -o [pool]:[port] -u [username].[worker] -p [password] --icarus-options 115200:1:1 --icarus-timing 3.0=100 -S //./COM3 -S //./COM4 -S //./COM5 -S //./COM6

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

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

I've also measured mine with a 'laser' (IR) 'thermometer' (pyrometer), but stopped when the top of the ASIC and the heatspreader on the bottom both exceeded 70 deg C (ambient ~26 deg C too and without any fans). The operating temp limit of some of the components on the PCB is just 85 deg C, getting too close for my comfort. On that topic, does anyone know if AM have released technical information about their chips with electrical data and some recommended temp limits? I fear that this information may be out there but in Chinese.

It is actually pretty hard to use a IR thermometer at close range because the laser beam (which has nothing to do with the temperature measurement and is intended as a crude indication of the measurement position) and the location that the thermopile sensor 'sees' and takes its measurement on are several centimeters different at close range (<6", usually), because they are designed to operate usually at distances of 6" or more and measure relatively large surface areas. For example my 12:1 optics model reads an average from a 1.5" diameter spot size at 12" distance. Most have fixed optics too so the best you can do is guesstimate what component is being measured at any time and if you end up measuring a site 50% over the top of the chip and 50% over the PCB, the sensor is giving an average reading which is going to mislead you and the actual component temps could be much higher than the averaged value shown on the display.

A while ago when I got my erupters I had planned to borrow one of my work's colour FLIR thermal imaging cameras but I have found that one has been taken offsite for unknown period of time and other fails cal and shuts itself down.

There is a file in the CGMiner archive called ASIC Readme.

I need a Windows 8 instructions on how to get the usb asic erupts to mine using cgminer

Thankyou.

just borrowed a laser thermometer and checked the temperature of my Block Erupter.

I put a tiny heatsink with some Arctic MX-4 thermal paste onto the ASIC and measured the following at room temp of about 26°C

- tiny heatsink top 51°C
- tiny heatsink bottom/side of ASIC 61°C
- side of pcb/heatspreader next to ASIC 60°C
- heatspreader below ASIC 38°C
- D-Link hub 35°C
- RPi CPU (also with a tiny heatsink on top) 37°C

HW error around 1%

I'm getting a USB fan tomorrow and will measure again

A thread here was very helpful getting my erupters going with an Anker hub using cgminer on Slush's and btcguild pools. Win7 though, not Win8 in my case: https://bitcointalksearch.org/topic/how-to-use-asicminer-block-erupters-with-cgminer-on-windows-7-220450

I doubt that the hub you use will have any restrictive effect on the pools you can use. Good luck!

They should work for any pool that you can mine SHA-256 algorithm coins on. You can even solo mine with them, but that would a bad idea for BTC unless you have hundreds of gigahash/s of erupters.

The hubs will either work with your OS and mining software or they will not. The pool doesn't really have much to do with it as far as I can see.

I have windows 8

I am only using usb asic erupters.

The only Bitcoin mining pool I have gotten to work is bitminter.

Will the Anker hubs that I am using with the usb asic erupters only do bitminter.

Thankyou.

Plug one hub into the Mother Board and the next Hub into the first Hub and so on and so fourth.  USB can handle something like 127 devices so you should be able to do that for a while if need be.
