Hi, i'm looking for an Alcheminer Controller Board 100% working. Please, send me a PM. Thanks.

still searching

i'm interested to buy one

Have you considered doing the mod to control it with a Raspberry Pi?  I haven't done it myself, but I used an RPi to reflash it, etc...

Yes, i'm trying it, but i have no idea how. I'll try to buy an USB to UART adapter and see, but i don't understand where to plug each pin  ???

It is easy to buy used one...  ;D

Same I bought one here was able to flash the boards with no issues but can't get it to run with a RPI if you do post the walk thu plz the one i found was missing a lot . or if you find a controller or two i need one they are nice miners but atm mine is a paper weight the boards get warm but can't get the RPI to control them. i won't give up .


I tried this guide seems to be missing some stuff

I asked  jstefanop and some one else who lives near me i was even wiling to give up two of the boards etc etc they never got back with me. i don't beg .!!! So :).

It's only easy to buy one used, if you CAN buy one used!  ;)

I didn't actually do it either, but it seemed straight forward - basically you're just replacing the normal cable and wiring directly to a UART (serial port).  The only thing that seemed a bit tricky is that you need to do that per blade, so basically you'd need to wire up 6 of them.

Personally I would hit up jstefanop again - offer to pay him to help you get a Pi running it.  Since he's the one who figured it out before, he could probably do it easier than anyone else.

Either way - just wanted to make sure you were aware of that option...

That's the same one I saw - FWIW, you can see the pin's he's using on the Pi are (left to right), Ground, TX, RX, and GPIO23 which he's wiring up to the Alcheminer's board reset pin.  He also has more detail here:

I had a couple of Alcheminers (I ported over Minera to it) and I quite liked their machines.

Now i have a RPI B running with all steps done, but not hashing. First step is to try to the gpio pins first. I have an error (file /home/admin/log.txt):

Traceback (most recent call last):
  File "asic_miner.py", line 1011, in <module>
    factory = WebSocketServerFactory('ws://127.0.0.1:9000', debug=True)
  File "/usr/local/lib/python2.7/dist-packages/autobahn/twisted/websocket.py", line 257, in __init__
    protocol.WebSocketServerFactory.__init__(self, *args, **kwargs)
TypeError: __init__() got an unexpected keyword argument 'debug'



NEED HELP!!

Python isn't one of the languages I use with any frequency, but the first thing I would do is remove the ", debug=True" from the WebSocketServerFactory parameters.  I looked online and I didn't see that as a valid parameter list...

 hey carlosmnk

 jstefanop just told me what's wrong i sent you a PM

here what he said  

Ok i see whats going on...yea that first AlcheMist_raspi branch was based off the old python driver which Im no longer supporting, and it wont even work with your flashed boards. You need the bfgminer driver. Now the issue with the bfgminer driver is that I need to update it to run it off those USB to UART dongles, since I need to program the reset pin to work with those. I should be able to do it but it will take a little time.

The rest i explained in a PM to you i won''t get into on the forums, no one needs to know :) .

Nice legwork on that toptek - it would be awesome if when it's all said and done some better instructions could be posted, since I'm sure other people will have this same issue, and that's what community is all about!  ;)

I started a post here with updated support for Alchemist miner with a broke  controller

Yes check that thread, i have 10-12 controller boards in perfect condition and complete with cables and even lcd display if needed.

Original Controller or only rpi? I buy one (original) controller from you if possible. See my message as PM. I hope it's not too late. Thanks!
