    Modular Python Bitcoin Miner


    The Modular Python Bitcoin Miner is a very flexible mining software written in Python, aiming to unify the frontend of FPGA-based mining hardware.


    Features

    • Runs on Python 2.6+ / 3.0+
    • Very flexible, to allow for all kinds of weird mining hardware and future mining pool protocols
    • Multi-pool support (load balancing or failover, configurable)
    • Multi-worker support
    • Worker hotplug support
    • Web interface
    • All UI functions available through JSON API
    • Can easily handle clusters of tens of gigahashes, dependinding on the board type


    Supported devices

    • Simple RS232-based interface, as a starting point for interface developers
    • X6500 FPGA mining board (no need for D2XX driver!)
    • Icarus board
    • ZTEX boards
    • Butterfly Labs (BFL) BitFORCE Single
    • ...more to follow!
    • Feel free to implement your own one!
    • Board vendors: Contact TheSeven with an offer (e.g. a board for testing) if you want your board to be added!

    News

    • 2012-03-26: v0.1.0beta released
    • 2012-03-22: Testing branch almost ready to be released for production use
    • 2012-03-21: Added ztex board support to testing branch
    • 2012-02-09: Added experimental support for Icarus board
    • 2012-02-06: Initial public beta release (v0.0.4beta)

    Donations

    • Donations to 13NuRX6rdE4Do4vddzhfKK7FqmGSTMcjYh are gratefully accepted Grin
    • Or, even better, donate a small share of your mining power to the MPBM authors by leaving the demo pool entries in the default configuration file enabled

    so without the D2xx-drivers we could get this thing running on OpenWRT?

    That depends on:
    • Availability of /dev/bus/usb
    • Availability of libusb
    • Availability of python
    • Available RAM etc.

    Is there a more detailed description for setting the scripts up avaidable ?

    I tried running it on my linux maschine but i keep getting errors for a common file.
    I guess my Pm to you dindn't reach you. Seems to be unreliable lately.

    That sounds like you're using Python <2.7 to me. Only 2.7 and 3.x is supported.

    @O_Shovah: I've responded to your PM now... Looks like common.py is missing for some reason? (I have no idea why...)

    Yes, 2.6.7 as standard for X6500.

    I tried 2.7, log has:

    http://sourceforge.net/projects/pyusb/files/PyUSB%201.0/1.0.0-alpha-2/pyusb-1.0.0a2.zip/download

    you can just unpack the "usb" directory from that zip file into the mpbm directory, or install it system-wide using setup.py

    Hi.

    Looking really good!

    Couple problems with v0.0.4alpha that I can see:
    1) curses line characters are all messed up in my locale  (en_AU.UTF-8) (let me know if you want a screenshot)
    2) I'm getting "Invalid long polling URL for Slushies: http://api.bitcoin.cz:8410"

    Thanks for this work, i'm loving the idea of one program to run ALL the FPGA's.

    I was working on a port with libftdi to replace the d2xx lib - it did not work, some bits in the data streams differ.
    Great work! I really need this stuff on openwrt... Grin

    Now getting:

    Not getting quite as far as coblee, as no board serial detected?

    Well, I put the serial in the config.py myself:

    Code:
      # Single X6500 worker
      { \
        # Worker module
        "type": worker.fpgamining.x6500.X6500Worker, \
        # Worker module parameters, in this case board serial number (default: take first available)
        "deviceid": "AH00WOWD", \
      }, \

      # Single X6500 worker
      { \
        # Worker module
        "type": worker.fpgamining.x6500.X6500Worker, \
        # Worker module parameters, in this case board serial number (default: take first available)
        "deviceid": "AH00WI18", \

    1) might be curses not properly detecting your terminal type. Running it inside a screen session sometimes helps with this. If you're using PuTTY as a terminal, make sure to set its charset to UTF-8.
    2) MPBM probably expects a trailing slash here... I'll fix that later today.

    I'm getting this error:

    Code:
    2012-02-06 20:25:26.472938: X6500 board AH00WOWD: No backend available
    2012-02-06 20:25:26.475037: X6500 board AH00WI18: dlsym(RTLD_DEFAULT, usb_find_busses): symbol not found

    Sounds like you don't have libusb installed or a weird version of it.

    Well, I put the serial in the config.py myself:

    Code:
      # Single X6500 worker
      { \
        # Worker module
        "type": worker.fpgamining.x6500.X6500Worker, \
        # Worker module parameters, in this case board serial number (default: take first available)
        "deviceid": "AH00WOWD", \
      }, \

      # Single X6500 worker
      { \
        # Worker module
        "type": worker.fpgamining.x6500.X6500Worker, \
        # Worker module parameters, in this case board serial number (default: take first available)
        "deviceid": "AH00WI18", \
      }, \

    If that works, autodetecting should have worked as well.

    I've had mpbm working using "useftd2xx":"true" and python 2.6.7.

    It saw all the boards, but couldn't "open" all of them.

    Seemed to be getting shares, pool reported widely varying hashrate. The terminal window has a message about "window too small" so no stats to relay.

    Froze around an hour later, no reason in the log.

    I like that it manages (or tries to) all the boards at once - much neater than multiple windows. I will persevere.
