The RPi has now been switched out for a Lenovo s10 netbook. Initial results are looking positive. The RPi has had problems seeing all of the devices, or seeing some initially but just hanging later. First attempt with the s10 it saw all of the devices immediately and started cranking away. Just letting it run for a while now to see where it gets.

A quick update, I am currently working on replacing the RPi with an unused netbook I have sitting around. The reliability of the RPi when running 21 usb devices is just not there. It hangs or drops every 4 or 5 hours or so, fairly randomly. When there was only 9 usb devices it was rock solid and ran for days.

They can mine SHA256 based systems, but not scrypt systems like litecoins.

  • Total invested (not including equipment I had on hand like the RPi and a few of the hubs): around $1187
  • Power draw: 82W
  • Income per week:  0.046 BTC at current difficulty
  • Hashing power: 9.5GH/sec

9 of the erupters were bought on amazon for $35 each
11 were bought across several ebay auctions around $50 each (varied per auction)
bitfury was bought on ebay for 280

In the next few days I also have a block erupter blade that I also bought on ebay which will bring my total hashing power to 19.5.

Things that need to be improved on this setup:
  • RPi struggles to keep up with this many USB devices. Another RPi (only $35) would make it more much stable.
  • No more USB erupters, for what I paid for them I could have bought two block erupter blades and have double rate I have now
  • Overclock the block erupters. Replace the oscilator with 16mhz to bring them up to 400-440MH/sec which would add ~2Gh/sec total

So far the bitfury has responded well to overclocking, getting close to 2.9Gh/sec after replacing R15 with an 850 ohm resistor

- How much total of money you spend on that system?
- How much power it have?
- And how much can you generate per week?

Thank you

The total is 20 of the 333Mh/sec erupters, one bitfury USB that I overclocked to 2.9Gh/sec. It averages about 9.4-9.5 Ghash/sec when running. Overall about $1500 into it so far, mostly from Amazon or Ebay.

Are those 333Mh/s Eruptors or the other 2.7 GH/s USB miners?

My mining setup here. It first started with a couple D-Link hubs and 9 block erupters. From that and the recent exchange jump I was able to buy 11 more block erupters and a red fury. All being run off my Raspberry Pi that I already had.
