Has there been any discussion on how to overclock an Erupter to achieve the 392 mh/s friedcat mentioned being possible?

If it is, it must S/W controlled. I've looked at the stick, I don't see any place place where you can adjust the voltage/current like on the blades.

I heard it regulated the W on board.

So IF say you plug in a 6.5v transformer into your usb hub it may just regulate it down to 5v.

I'd like to see it done though.
Wonder if it will blow anything on your computer through the USB connection to it though???

I'm not sure if you'd be able to do it within cgminer, have you tried? Similar to how you can adjust GPU clocks, maybe the voltage of the stick can be changed. Huh

I can confirm it does not work with the Anker 10 port hubs with the PI.

I have some posts getting 45 of these to work on the PI here starting here:

Can anyone confirm if the Anker 10-port USB hub works with RPi?

Thanks! Added note to main page.

Did anyone figure out how to run it on a mac?

There is a mac only thread here somewhere. Try there.
Please let me know what you find out.

I am also seeing about 1% HW errors - and my units are no longer hot now that I have moved things around a bit.
I believe these numbers to probably be normal Undecided

I get about 1-1.5% HW errors. I only have one erupter, so it isn't a sufficiently large data set. I'm hanging the erupter with a usb extension cable in front of a box fan.

why is the HW error so high on erupters?

What I have discovered so far is that some are expected and others are due to too much heat. I have also seen posts noting conflicts with certain software and USB3.0 Hubs. Last I saw is patches were being developed and by now may have already been completed.

Let me know what you find out.

Any recommended pools to run a couple of these things on (i.e. for small fish)?

I started mining with my Erupter / Raspberry Pi yesterday.

I'm running the hard-float Raspbian image (2013-02-09-wheezy-raspbian) from raspberrypi.org on my pi. I liked MinePeon but when I tried it there was no way to upgrade the system other than completely rewriting the SD card with a new image. I had trouble getting my wifi working with the arch linux image from raspberrypi.org.

I'm mining on the rpi with cgminer v3.1.1. I downloaded a tar of the tagged version from github (https://github.com/ckolivas/cgminer). Build dependencies were installed with apt-get. I had to set my LD_LIBRARY_PATH so that it could find the jansson library. I'm using the following hardware-specific cgminer options:

--icarus-options 115200:1:1 --icarus-timing 3.0=100 -S /dev/ttyUSB0

I have this Manhattan hub (http://www.adafruit.com/products/961) which I would not recommend for Erupter mining due to the layout of the ports. I'll be replacing it with the DLink DUB-H7 mentioned earlier in this thread.

Thanks! ........ Info. Posted.

This wikipedia page has an overwhelming amount of information about various pools:
https://en.bitcoin.it/wiki/Comparison_of_mining_pools

I starting mining on Eligius (http://eligius.st/~gateway/) yesterday. It was attractive to me because you don't need an account to get started.

Redcomet and ALL!

Awesome work!

I think we are eventually going to have too much info. to post on main page.

Thanks for TWEAKING your post with your data making it user friendly.

I will grow the lists of the main categories as time permits and then have the "Running Rigs Links"
for each of the Rigs Posting with their Data as you have.

Your efforts no doubt will help many get their Rigs up and Running!

Well Done and Much Thanks!

i ordered this 10-port, 3.5A hub: http://www.newegg.ca/Product/Product.aspx?Item=N82E16817182257

should be good enough to power my 5 miners (~2.5A).

i've heard reports of people having success using Rosewill hubs with the Raspberry Pi, so I'll be giving that a try with MinePeon as well.

That's a 3.5A you've got there. and 2.0

I heard the 3.0 is better due to increase in amps per hub.
edit: Though I have heard some software has issues with 3.0 hubs.

However the 3.0 listed and proven Hub is 4A.
So at 2.5W ea. the 4amp gets you 8pcs Erupters.

The 3.5amp gets you 7pcs Erupters.
Not including powering any fans.

However IF the transformer powering the hub is external you could find a 4 or 5amp one and switch it out.

IF you buy a Hub at half the cost and power 5 Erupters and a fan while skipping every other port
it may aid in keeping heat down or need of a fan in certain circumstances.
Especially IF you have the Hub mounted on something skinny to aid air flow from underneath.
IF the Hub is on a completely flat surface (as most are) it does not pull cooler air from below
efficiently enough to cool them properly IMO. And the entire Hub gets warm.

This Hub has a switch to possibly Power 6 or 10 ports.
There may be "limiters" on each port.

I'm trying only to post known "in use proven" hardware etc. on the main page.
Let me know how it works out!
