Block Eruptors only do the SHA-256 algorithm, and are not capable of Scrypt. Ergo they cannot mine litecoins.

Cool, thanks for the explanation. A sudo reboot fixed everything for me.

Neil: I am having stability issues with MinePeon 0.2.2 (cgminer 3.3.1)  This seems happen after donation. . . |

From my thread: Any idea how much electricity cost the setup is per day/month?
My energy provider is ActewAGL, and my bill has 2 components: a flat fee of AUD$0.605 per day, plus AUD$0.179 per kWh. The rig draws 20W at most. So to run for thirty days is 30 days * 24 hours * 0.020kW * AUD$0.179 = AUD$2.58 |

UPDATE!! 2013-08-06
My first CD has matured, and I have paid out all my mining profits. Not as much as I'd hoped, but now I have some liquidity. What will be my next move?
Buy more AMUs? Buy alternative hardware? Another CD? Cash out to fiat? Invest in shares or derivatives?
Give me a suggestion with a rationale and I will consider it!!

Nope, never figured this one out. . .

I highly recommend using MinePeon, a RasPi distro specifically for BitCoin mining. You just install it to your SD card, plug it in, boot up, input pool settings, and you're good!

an export/import settings feature would be nice. . .

It looks to me like you are calculating (accept/reject) / 100, rather than (reject/accept) * 100. Are you taking the reciprocal somewhere?  EDIT: Same bug affects error rate too. |
|

I think there's a bug in the Minepeon 0.2.2 status screen: How is the "Reject" column in "Device Status" calculated? The percentages seem rather high on my system:  |

Hi Neil,
my cgminer on MinePeon 0.2.1 has stopped, and I can't get it running again. sudo screen -r just results in "There is no screen to be resumed". I've also tried sudo systemctl start cgminer.service and nothing happens. How can I restart my miner?
Sometimes I find it faster, especially when you are down, to just re-flash the SD, put in your pool settings and go. Time is money. Yep, that's exactly what I did.  |

Since then I've ordered 10 more ASIC sticks, another DLINK hub and another fan. I'm planning to daisy chain the Hubs together and hopfully run 6 devices on the second Hub. Hoping it will support 6 sticks and a fan...
The d-link outputs up to 3A which is enough to power 6 ASICs, but not an additional fan. It's also very physically difficult to get the fan to fit when it's plugged into the hub. I recommend getting an extra USB power supply for the fan. |

Mini-update:
I currently have 0.61370383 BTC balance in my primary mining pool, and 0.00073648 BTC balance in my secondary. The Certificate of Deposit will mature on 2013-08-06, and my return will be 1.02393825 BTC from a principal of 1.005 BTC. The plan is to pay out and reinvest everything when the CD matures.

Have you consider increasing your cooling capacity? I heard these usb miners can run pretty hot.
They run hot indeed. Without cooling, they are too hot to touch. A few hours before the instability, I noticed that my fan was caught on something and had stopped spinning. This *could* be the cause of the problem. I'll keep an eye on it and keep you updated. |

Had my first stability issue for over a month just now. cgminer was detecting ten AMUs instead of five. I unplugged/plugged the USB hub, and Quit and resumed cgminer with sudo screen -r, and that seemed to fix it.

just to be clear, difficulty rising as a result of Hashrate increase stablizes the return, it does not reduce it. the ever increasing hashrate reduces your return.
Thanks for the clarification. Here is a page on difficulty I found helpful |

Thanks for the update.
what happened around the 15th for the earnings to dip?
the hash rate remained stable, is this just random variation in difficulty?
Andy.
As far as I know, difficulty doesn't vary randomly. It increases (and theoretically decreases) depending on the hashing power of the network. As the hashrate rises, difficulty goes up, reducing the return. As time goes on, my miners will become less and less effective, making it very hard to achieve ROI. I now have to decide whether to a) buy more miners to keep up with rising difficulty; b) cut my losses and sell the rig; c) continue mining at 1.67GH/s. |

 Here is a graph of my first month's mining performance on my primary pool. You can clearly see the initial instability, and the two decreases in earned rate due to higher difficulty. |

Without cooling, I saw problems with my Block Erupters after a couple of days.
