Topic: Linux mining distro for the Raspberry PI - MinePeon - page 103. (Read 685046 times)

Hi,

i did a


today and now a click on the settings page throws an server error 500 at me.

Also i want to tell that it would be nice if there would be a disable button on the pool page, to disable single pools.

thanks

fr00p

So, I just set up a Raspberry Pi with MinePeon for the first time tonight.  Bloody awesome is the only term to describe it. =) Here's some things that weren't so obvious for me, and made me thrash around madly.

1) When using wicd-curses, you have to go into the Preferences screen and manually type in "wlan0" (without quotes) in the wireless interface box.  If you don't do that, you will tear your hair out, cuss and yell at your hapless Pi, and just generally be grumpy because wicd-curses doesn't see your wireless adapter.

2) A quick-and-dirty way to restart the miner is to go to the Pools screen and hit submit (without actually changing any settings).

3) I think something is off in the % calculations in the stats for accepted (A), Rejected (R), and Errors (E).  Take a look at these screenshots.  My best guess is that you're calculating the percents as A / R * 100 and A / E * 100.  I think the right formulas would be: R / (A + R + E) * 100 and E / (A + R + E) * 100.





4) For some reason, MinePeon doesn't update its time automatically, even after about a half hour.  (This may be my fault, as I started updating and reinstalling all kinds of crap when I was attempting to fix #1, before I discovered the real fix.) I have to manually SSH in and run sudo /usr/bin/ntpd -s.  However, that causes either cgminer or the stats display on the Web to bug out; whichever it is, the hash rate starts showing as zero when the time changes.  So, I have to do a quick reset using #2 above.  This restores things to normal.  You could probably test this by starting MinePeon and letting it run for a few minutes, then ssh'ing in and using date to set the date 30 years into the future.

I know absolutely zero about MinePeon, except that it runs an instance of cgminer in the background, I believe. If that's the true, and if the API is enabled on the cgminer instance, then my python script should work.

Sorry if I'm showing my naiveté here, I'm talking about things I don't know about...  

Hi Kano,

Here's the link to to code on github:

https://github.com/cardcomm/cgminerLCDStats

Sorry for the delay. I got bogged down last night with some last minute changes adding some rounding code. I belatedly realized the display would get badly scrambled if the hash rate was too large. I'm still not sure how well it's going to display higher average hash rates - looking for your input on that one since I only have the one Block Erupter at the moment  haha

Also, I'm attempting to check for problems with cgminer, and display a warning screen. Right now I'm showing the error screen if I can't connect to the API, if cgminer isn't returning "Alive" in the STATUS call, or if the NOTIFY call is returning "Reason Not Well" other than none, or a "Last Not Well" code of non-zero. Is there anything else I should be checking?

Thanks for trying the code, looking forward to any feedback you have.

I try to run an avalon unit via minepeon, disconnected the internal USB from the wrt703 router and plugged it in the same hub as the USB-Miner but I won't regognize.. any ideas ?

Please try to "kill a cat" and you'll see the problem is solved... But I can't do any more comments or I'm risking to be slapped again by Neil...

See my comment, regarding this problem, in this thread (and Neil's answer): https://bitcointalksearch.org/topic/m.2732667

Unfortunately, same here. Last night 00:00, dead. Had to restart the pi this morning.

Hi cardcomm (again)
Could you post a link to what you've done please?
As I said, would be good to have anything useful showing on it rather than just the time
(Yes I will get to doing something about it soon ...)

I also received my new "USB 2.8" TFT LCD module LCD". I hope that one day, MinePeon will interact with this display. But with this comment, I'm NOT ASKING ANYTHING to Neil, or he will ban me for life.

Thanks for your replies,
sounds there is some trouble between free software developers and hardware companys.

BKK and Burnin will deliver their own cgminer driver. I believe cgminer have to be compiled with this drivers.
Obviously I over estimated the importance of these custom designs, so i thought there will be a newer MinePeon version with the special compiled
cgminer.

Greetings


P.s. Link for Burnins Bitburner:

Wait what? Which USB3 Hub exactly and what did you have to change in Minepeon (say 0.2.2) to make the hub work?

Yep post a link I'll even run it - the clock next to me is getting rather boring

Yeah, I know what you mean. I'm not a big python fan either. lol! But I hacked together a little python script that displays a few basic cgminer stats. Sorta arbitrary choices based on what I though was most important to display and the limited space to display it.

If there is any interest, I'll clean it up and throw it up on github as an open source app. I do need to add code to display an error if all devices stop hashing. (I already show an error if cgminer doesn't respond "alive" on status, or if there's a network connection.) I know I overlooked it, but what gcminer API should I look at to find out if hashing devices have failed to stopped?

I'm including a screen shot of it running on my Pi mining with one Block Erupter. Let me know if anyone wants this up on github.

I think neither of them will work up front.
BKK has written a cgminer driver for the Klondike (and I have provided minor input into that) but I've no idea what's actually going to happen there with the actual hardware.

Bitburner? We've never heard anything from them.
If it is a pure Avalon clone, it may work.
But I've also got nothing to do with Avalon at all (ckolivas has one) so I can't say what will happen there.
(He had to pay for his Avalon ... 50BTC ... and since then the Avalon performance has gone from ~70GH/s to ~80GH/s thanks to him ...)

The problem is that a lot of people seem to think we ask for hardware with an agenda to simply be given stuff for free.
(The whole Me vs GitSyncom drama should have made that clear - "proper support" is provided by ckolivas - many months after they said they would provide it but never did)

When Klondike finally appears and people release them, the basic board is like ... 15GH/s?
So yeah I'm really gonna make a fortune from that in a month or two
Next week I'll have 130GH/s courtesy of the company that a lot of people hate (I already have 70)
So it sorta puts the whole "You only want a Klondike for free" into the realms of ... why should I have people abuse me for that ...

I sold an Icarus for $1800 back in Apr coz I had 2, I kept the 2nd one coz I need it to support cgminer.
I will keep the 'tiny' devices mining probably long after they cost more to run than they generate coz it means I can easily test changes on the hardware "We Support"

Yes it peeves me also

... and I will add of course what most know but never hurts to remind people, MineForeman.com paid and posted my RPi to me.
Thanks again

... and sorry to derail the thread ... yeah this is how I sometimes start a war around here ... but I don't think it will this time

I agree.  Now that I'm avoiding the "blown" USB ports, and connecting less Erupters per hub, my hubs seem stable for now.  No issues last night.  I actually got up at midnight to watch it, to make sure everything went ok.  The changeover to donation time was very smooth.  Funnily enough, as I watched my rig mining for MineForeman I felt happy - glad to be donating a few hashes, and grateful for the excellent MinePeon that makes life as a miner so much easier.  

I will be replacing the hubs that have "blown" ports very soon.  I have decided to play it safe with hubs, and not risk overloading them.  I think Erupters actually use a little bit more than 500mA.  I was connecting 6 of them to a 3A hub, because 0.5A x 6 = 3A.  Problem is, I think the Erupters were drawing more than 3A at times... and hence blew my hubs.  So now I connect one less Erupter per hub than theoretically possible, to stay within the limits of the hub.

Thanks, I enjoy doing it and I am glad you enjoy using it.


Possibly (probably).  I believe they both use standard drivers that are already present in cgminer and bfgminer.

Neil

P.S. It is one of my pet peeves that mining hardware companies release these things and expect the developers to buy a device to build support for them.  At the very least they should be sending one to Con, Kano and Luke.

Hey,
at first thanks for your nice work!

Will MinePeon work out of the box with Klondikes K16 and Burnins Bitburner?

I've had 8 SC and 2 FPGA on one Pi running MinePeon 0.2.2, it worked, only ran it for a day or so. I opted for one Pi per shelf in the rack so if I had a failure, I minimized the impact. Time is money, redundancy is king. Pi r cheap. (Or Pi r squared, whichever you prefer.  )

BFL asics and stratum

Obviously depends on the devices and the pool protocol ...
