I grabbed an old RVK extractor from a part dismantled bathroom. The miners are mounted in a plastic box, with a hole cut into the lid to feed the air in and the PSUs outside the whole thing. Near constant uptime.  Kiss

Just let em mine and when they die they will probably not fetch more than 0.00001 a month.

That is awesome, do you mind divulging what you earn in btc a week/month at the current difficulty.

it looks like about 58 erupters, roughly 19 Ghash. at about .003 per Gh/s per day he is making roughly .057 BTC a day at the current difficulty.

Man, so disappointing how mining went from gpus everyone could get, to being another luxury afforded primarily to the one percenters. I wanted to buy 5-8 earlier in the week but really you see the sellers sitting on 100+ and you'd think if they actually were profitable they would be used themselves.

is your time really worth the 10 dollars possibly mined from these at this point?  The cost of getting more hubs...the time to resolve power issues.  I just put together this setup basically and it took hella time to get the usbs figured out and working right.  I think there is a hardware limit of 127 different usb components onto one os too which leads me to think there are other limits on mining with these style devices.

it is my understanding that it is 127 per controller. one computer can have multiple controllers. But you can only daisy chain 5 deep.

I'm tempted to crack an egg over one just to see if it'll cook even slightly. I'll first check if egg white is conductive though!

Yes that picture was with 56 miners and I just added 14 more since this picture was taken so I am at 70 now running at 23.6 GHs. I mine on Slush's pool and depending on the pool luck but I think I may be closer to .10-.07 per day now. I also put up a blog with information on the hardware that I used http://aurel57.blog.com/

I am only at 70 miners and start up is tuff to get them all going. I had started out daisy chaining and didn't like that at all, so I have two main 10 port hubs plugged into the computer with 5 hubs plugged into each for now. I have enough power from my 3 PSU's to still power 20 more miners before I need to add another PSU. I was kind of wondering what my limit is on one computer.  Here is a picture of 70 miners running with 3 PSU

Is it even still profitable to mine with BEs?

If you buy them for cheap enough.

Which is impossible. They basically need to be free.

Primary developer/maintainer for cgminer and ckpool/ckproxy.
ZERO FEE Pooled mining at ckpool.org 1% Fee Solo mining at solo.ckpool.org

Which also is impossible, if they where 20$ in the beginning with a fixed price they would have sold way and way more BE and we could actually make ROI with them.
