unless yer overclocking, in an open case, with a fan....a cpu heatsink is useless on a pi...

Yeah runs at 64.8 even with that! 975 core/475 cache/500 ram at 1.35v. Gonna reformat it soon and make it into a lil VPN/fileserver and send it off for free colocation, running it as a miner is a bit pointless at 0.48khash/s. Stock speed is normally 0.33khash/s! |

Nice device! Can you add mtgox live prices?

Good idea - added to my list. Also had an earlier version of the script displaying confirmed+unconfirmed rewards total pulled from the pool. May add it back in if there's interest … |

how many usb block erupters can the rasberry pi handle?
it has two usb connections, so can I hook up 2 x 10 port hubs to it?
i would assume that the hard limit would be 127 *2 USB devices? depending on whether the the two USB ports are separate controllers... the 2 ports are from a single bus... |

The 700Mhz ARMv6 will become the bottleneck before 127 USB devices I would have thought. |

apparently you 'can' overclock the CPU - i dont know how or to what value - i'd definately investigate cooling - as i've seen people say they've over clocked to 800mhz just googled and found this: http://www.jeremymorgan.com/tutorials/raspberry-pi/how-to-overclock-raspberry-pi/1000Mhz and much improved RAM speed? I think thats a win BUT i'd definiatly want a cooler on the chip  |

Trouble with that is that overclocking often corrupts the SD card requiring a complete reinstall. Gonna be a bit of a pain if your miner goes down cause of this, mine is at 975 core/475 cache/500 mem with +0.15v Heat shouldn't be too much of an issue; it only gets to 64 degrees even with a little aluminium ramsink and a sealed plastic case (see top post on this page) after 3 days of LTC mining on the CPU. But I certainly won't run it this way for long! When I send it off to the datacentre it'll definitely be back to stock - not worth risking it; the performance is so low anyway, even 30% more is still really slow! |

Ask here for troubleshooting help? If not I'll edit this out to keep your post clean. I ran through the Adafruit tutorial with both the Raspbian and the Occ distros with the same results. I get to the part where you start cgminer and then PiMiner and nothing seems to happen. The LEDs on the USB sticks stay solid and the LCD says "no connection to cgminer" http://imgur.com/M8u95D8Thanks Rotor |

You can OC the rPi all you all you want, it's still going to be slow. It's an ARMv6 CPU. They've been using ARMv7 for years now, and ARMv8 is coming out in the next year or so (gonna be sweet!). That's like OCing a PIII to compete with an i3.

Yea 2 usb block erupters miners they showed as usb0 and 1. Edit: same ones from the tutorial. The also work fine on my PC, so I know it's not an equipment problem from that side. |

And it's a powered USB hub capable of supplying a full 500mA to each port? |
