On behalf of UKNova might I remind you that they do not allow invite trading. Their members are sworn to only invite people they trust.
If any trading is discovered the 'seller' and the 'buyer(s)' will have their accounts disabled.

I am not a Raspi-boi, but they are ridiculously cheap and use next to no power compared to a "good ole" PC, whatever OS it is running.
Getting USB miners recognised and connected under Windows is a game of chance, whereas Minepeon has accepted all of mine immediately.
I am running miners on both a Raspi and a Epia Mini-ITX Linux box (Arch Linux/bfgminer on a 900 MHz CPU), I haven't really noticed either being particularly slow - what sort of slowdown are you seeing? Web interface, bfgminer text display...?
As for using a mobile (smart) phone to control your miner.. well if you have one to spare then you're lucky - but it's a little difficult to imagine running a miner controller on one (though you can actually mine with the CPU).

If you check the bfgminer thread (i.e. this https://bitcointalk.org/index.php?topic=626361.msg6958527#msg6958527) then you would see that the BFL Monarch support was added in version 4.0.0. of bfgminer. So (at least with minepeon) you need to update from your old version of bfgminer. You don't say which version you use under Ubuntu.

Off topic I know, but the Arch Linux repo version is still at 4.5.0, any way (or need) to update to 4.7.0?

[ETA] OK now 4.7.0-1 is now available via pacman.

Would http://www.flotcharts.org/ be any good?

Yes, it was deleted so apparently it works.
As far as the graphs are concerned I was going to suggest the Google Charts Api since the simpler Google Chart Tools look like they are going to be retired in 2015.
If I were you I would contact Highstock and ask about the Hichchart license, it appears to be only $80 for a single web page that is not considered as a "web application".

Brutal security is far better than weak security!

Still don't know if the donation works, (currently set for 13 minutes at 18:00 CEST).

Now testing MPRPI20140815-R-0.3.0-PR2 - api looks to be working fine and I will leave it turned on. Weekly, Monthly and Yearly hashrates just show the png file name, maybe they need to have at least one data point before they show?
Donations turned on, how can I tell if they are working?
Great work dude!

[ETA] After about half an hour I got a point on the weekly chart and the others appeared! Question answered...

Did you run SDFormatter on the card before writing the image with Win32DiskImager?
Have you got the latest stable version of Win32DiskImager? I used version 0.9.5 and it worked fine for me. However the RPI did not start on the first try, so I unplugged it, removed/resinserted the SDcard and then it started just fine.
Beware that your RPI might change its IP address when you change to a new version, it is best to give it a reserved address in your router so that it always uses the same IP.

Neil,

Is there any way that Minepeon could support mining both BTC and LTC at the same time? (like Multiminer).
I suspect that I can manually start a second instance of bfgminer with the --scrypt option, but it would be cool to be able to manage it all at once via Minepeon.

Again congratulations for your excellent work!

(Small) Bug Report on RPI20140804 version.

• "document.body.style.background = "#FFFFCF"" appears after the device table on the status page.
• Donation amount in the plea should be 0.00000027 BTC, not 0.00027, per GH/s/day,
• Timezone reset itself to Africa/Abidjan (first in the list) overnight (there may have been a power cut). Similarly Expected Devices and Expected Hashrate show blank.
• Settings backup creates an empty file, probably still on the TODO list?

Thanks for all the work Neil!

Downloaded MPRPI20140804.img, wrote to SD card, popped it into the RPI B+, started up, set pools, plugged in USB cable and it runs like a dream!
Thanks Neil.

Excellent! Thanks for the hard work.

OK, so not so good. Installed MPRPI20140711 test build which is missing the miners (/opt/minepeon/bin just has hashrate.php in it).
A "git pull" told me that I was up to date.
I could always grab the source and compile it, but that means going through all the rigmarole of installing the compiler etc.

On the plus side, the web interface works just fine.

Back to the older version for the time being.

[ETA] Found that the "default" miner command was incorrect, changed to point to /usr/bin/bfgminer.
It does not appear to start automatically, but can be run from the command line and then the web interface picks it up.

Aww thanks.
Will be trying the more recent MPRPI20140711 test build later this weekend once I have got another micro SD card.
Will report back (I may be some time).

Raspberry PI B+ trials - the story so far.
Having lost my spare RPI I went out and bought a B+, totally forgetting to check if it was 100% compatible with the B.
Tried the "latest" MinePeon image (0.2.4.6) and of course got no USB or Ethernet.
Googled a bit ands decided to try the Arch Linux upgrade route on an older RPI. This fell over because my older RPI is very finnicky about SD Cards and borked every time I tried it.
Then tried starting from a recent Linux Arch image (works fine) and manually adding and configuring MinePeon (and Apache, php, rrd etc.). This failed due to my inexperience and the refusal by git to bring in the minepeon/http directory.
Finally decided to try MineForeman's testing build (MPRPI20130727) which booted fine. Struggled a bit to find the correct login/password (see higher in this thread for the answer) and then wondered what to do next when presented by "#" in Putty 

After some fiddling and more Googling I found the following:

• bfgminer starts automatically on boot
• "screen -r" brings up the bfgminer control screen
• You can add your own pools and delete the pre-configured ones, but changes are not saved! (or not to the right place)
• Edit /opt/minepeon/etc/miner.conf to set your pool(s) instead
• There is also a file called /opt/minepeon/etc/miner.user.conf, contents appear to be identical to miner.conf, so I edited this too
• Reboot and mine away!

I haven't yet found out how to get the web interface working (if there is one), for the moment it just gives me a 503, perhaps Neil could give me some pointers?
Working fine with 2 Bi*Furies, next job to get the Gridseed Dual connected.

Finally a note about USB 3 hubs. I got one that was recommended for USB ASICS, a Tecknet 10 port with 12V 4A supply. This hub has been the bane of my life under Windows and totally failed to work with the Raspberry PI B or B+ (lights up on insertion and then goes out). I changed to a cheap and nasty unbranded USB3 hub with a 5V 4A supply and it's working fine.

I hope that this post will be of help to new RPI B+ owners.
