Topic: Raspberry Pi Running Antminer U1 (Read 13191 times)

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.

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.

With either CGminer or BFGminer it lists QTY "HW"

where does it say the hw error?

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

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

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

greenemso

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!

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

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.

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.

Hey Sweaving, What is your next plan with your antminers? Are you going to keep at mining bitcoin or try something else?  I'm looking for inspiration really as I have a couple of antminer which are mining as we speak in slush until i get my 0.01 min payout.  I'm a little unsure whether I should get another antminer or just sell them once I've got my 0.01?  I only originally got them so I could learn a little about how mining works. They aren't costing me anything to run as electricity is included in my rent.  Are you planning on adding to your miners? Also, the mining difficulty is going to be ridiculous for people with only a few gh/s like us soon won't it?

All,
For referance, i had been running 3 Ants at 2.0gh with a fan, they seem to be ticking along nicely, with no down time and maybe around 0.02% share reject rate. so im a happy bunny. just had my first payout from Slush Pool 0.01BTC!

when you say going offline do you mean internet connection? or cgminer? or the pi just shuts off?

did the "debug" work?

when you save do Ctrl +X then enter to confirm the overwrite, it should be perminant!


PS if ive helped any1 and they want to make a small donation (LOL)!

Hi Lucky, yes I'm running on pi - I did enter that and x and y'ed it - but when I have checked back on just now the command had gone back to original (without slub_debug).. i guess I have to add each time?!

thanks

greenemso

"If you are using a Raspberry Pi do the following:

sudo nano /boot/cmdline.txt

Add the following code at the end of the first line (on the same line as the other text)

slub_debug=FP"

Business of the century

One antminer costs £59.9 + posting at cryptoware (unfortunatelly its sold out now)

Hi Sweaving

I'm having a few issues with CG Miner going offline after a few hours - I keep rebooting and its all looking fine, but same thing keeps happening - any ideas? 

thanks

greenemso

So far, since they arrived around 2 weeks ago, I've earned 0.01202089 BTC with Slush's Pool having overclocked my 3 Antminer U1s to 2.2GH/s after a few days testing at 1.6 and 2 GH/s.
Using preev.com BTC/USD/GBP currency exchange calculator, I've earnt almost £6 at the current exchange rate. While it's nothing huge, it's decent and more than covers energy cost. I am yet to see whether they'll break even though!!

Question
What success are people having.
Are you generating any bitcoins?
How much if you don't mind saying.
Thanks

Hi,
What terminal/SSH app are you using on iPad?
