Raspberry Pi Running Antminer U1

[LuckyDime]

I've started mining with one asic miner (333MHash) in october 16, now I have two, and third is on posting. I already have 0.03BTC, next 0.01BTC is on the way (~70%) I think with my ~1GHash, I will stop buying miners for a while.

By the way, if I cool the miners with a fan (i've  bought one yesterday) could they mining more effectively, or just increasing the life period?

No, if you write it to /boot/cmdline.txt you don't need to do it again. It will start also with every boot.

I have 1 more Ant on order and that will fill my small hub, just going to let em run in the corner! once i have enough BTC i will then spend that on a bigger hub, and keep putting my BTC in more miners, hopfully growing my empire!..lol

So what have i done is made my initial investment, and now said to myself it either live or dies by its own mining potential. will see what happens over the next year if i make enough btc to keep expanding, hopfully keeping up/ahead of difficulty growth and slowly increase payout frequency.

Wait and see now.

 

Oh and cooling simply extends unit life! it may help with reliability as well.


If Anyone is interested i do have 3 BE's on ebay at the moment! just in a straight auction.

Thanks all

I'm not sure what is stopping cg miner or the pi - no error logs to speak of, just stalled screen - I've taken off the LCD display (used for the BE's) in case this is causing issue.

Cheers

does the pi run ok with nothing plugged in? do the antminers work ok on a pc? all i can sugest is start ruling things out that it cannot be!

[greenemso]

thanks swearing - good idea.

just happened to see it go down just now and got this on the ssh:-

Pi works fine on its own, will test the miners on my pc tomorrow!  Slush's pool has reported some issues yesterday which may have been cause - perhaps still happening today too..

thanks

im on slush, and they have been running ok for me all day.

Just thought i would add an update into this thread!

I have been running the forked version of cgminer, with 5xU1 overclocked at 2.0gh (about 1 week) and have noticed about 6-7% HW (Hardware)erros! 1stly has anyone else seen this?
I have tried to fix this by converting a PC PSU to power my hub! however this has made no difference.

I have now installed bfgminer and is running very nicely, with so far only a 0.2% HW error (and this was from start up) so my thoughts are that the forked version of cgminer is unstable! and may be best to wait until an official one has been released.

I am keen to see what other people experiance are with cgminer, so please let me know.

Thanks

where does it say the hw error?

[sweaving]

With either CGminer or BFGminer it lists QTY "HW"

Hi I am new to the forum.  I have a question regarding piminer with BEs and Antminer.  If two instances of CGminer need to be running to support BEs and Antminers on the same hub, will piminer be able to display information from both instances of CGminer?  Sorry if the question sounds confusing.  Thank you in advance!

I just came across this site where the guy updated the Adafruit PiMiner program to run the lcd for newer versions of cgminer. I tried to load it but got an error while trying to 'git clone' and no time now to troubleshoot...
I'd like to know how to modify it to display both the Antminers and the BE.

Mine both, huh? Well I have been working on a expansion script that allows you to use an LCD screen (like those cheap 3.5" ones), which does work. I'll have to see if I can't make it work on reading and combining information from two or more sources. Should be simple enough. Adjusting my personal script should give me an idea on how to modify the other one (since mine uses the classes from that project).

I am just having a migraine getting the files due to an earlier experiment of running my mining enclosure in the garage. Funny to see it stay at 18C while also doing scrypt mining on the CPU. I'll post back once I have things working.
