Hi Guys

Long time and I'm glad to be back.  I used to have a nice little set-up running x13 Newpacs's and x2 R606 pods on x2 Pi4's at a stable 3.4TH/s for weeks at a time.  I have retired most of the equipment, but looking to get back into it under solar power.  Has anyone done this, are there any good links within the fourm and is this actually sustainable 24/7 with the correct set-up?  I was planning on x2 12v 100Ah batteries in parallel, a 600W solar panel, 60A charge controller and a 3000W inverter.  I will only be running x1 Pi4 and x1 GS hub for now.

Any help is appreciated.

Thanks

Greetings all

It's time to move on to other projects so I am selling all my Gekkoscience R606 and Newpac equipment.  Due to the apocalypse, I have lost my contract with work and therefore my work room when away from home that provided the secret power to run my rig. 

Please see fleaBay item 184326610212 and/or contact me at freddyhardest464@gmail.com.  I'm open to offer's and if you're in the UK, then I'm sure we can sort something out to collect/deliver.

Thank you so much for all your help in the initial stages and I am so pleased with myself that I managed such a project.  All x13 Newpac's and x2 R606 Pods run super smooth and the Hydra III case provides an excellent platform to start playing around with cooling and design.  Offers welcome and if anything, I would like to see a return of my hardware costs.

I'll be back in one way, shape or form so take care and stay safe.

Regards

Does this help?

Hi zsmith and all  

I wonder if you can help again before I headbutt my keyboard   I must be doing something wrong or have a script/permission issue.  My saved mine.sh text file reads as this:


I changed the file permission as 'only owner' and played around with all sorts of commands from page 7 and 66.  No lines of code seem to work in either:


or


These commands don't work in crontab -e:


or


Once I save/exit out of crontab, it does say a new crontab instruction has been saved but nothing auto-starts from the GUI desktop after a test reboot.  I've read up and watched online videos that make it seem so easy and makes me wonder if there's a root, path, permission or script problem?  I'm using noobs/raspbian and recent to this phase of the project, I carried out a:


Would this 'full-upgrade' instead of just the normal 'upgrade' have caused an effect and is there a way to revert versions if this is part of the issue?  I'm happy enough running 24/7 with no issues but really want to nail this last phase in-case of power, network and zombie problems when afk.  Thanks in advance  

Hi GT, I may have caused slight confusion.  I would like to programme a weekly reboot of the Pis and a daily/36hr reboot of cgminer.  My set-up is away from home and I can't SSH into it with my USB broadband dongle.  Therefore, refreshing the devices at those intervals was my plan of running stable   I've tried /etc/rc.local and crontab -e scripts but it seems I have permission/path issues that I haven't bottomed out yet as nothing happens after a sudo reboot.

Hi zsmith and all

When you say "save this code as mine.sh" , do you mean opening a text file then saving it as mine.sh in my cgminer folder? e.g. /home/pi/git/vtoang/cgminer/mine.sh?

Can I run a similar file for more instances such as mine2.sh and mine3.sh?  I run more than one instance for different R606' and Newpac's.

What would be the script to reboot the Pi4 weekly (e.g. 0100hrs every Monday) then to reboot each cgminer .sh file every 24hrs?

Does running the auto-reboot script commence from executing the .sh file and how would that conflict with the Pi4 reboot timing per week?

Would sleep 86400 = 24hrs?

Whats the sleep 4 at the end for?

Thank you in advance from a novice although I've loved this project build.  I can see the end in sight and all I need is to programme the Pi4's and miners to refresh on command

Oh sorry Sam! Haha, for a one-off no blank per reboot it's:


There is a way to permanently do this but it didn't work for me. No doubt it's my finger trouble! Good luck.

I've tried sudo crontab -e then entered before exit 0:


This is for a continual 12hr reboot but doesn't work. Am I missing more code?

Hello all, I would like some help with programming the Pi to auto reboot every 12hrs or so with the cgminer folder opening and any chosen .sh files to auto run within it.  I've tried the commands in the previous couple of posts to do with:

sudo crontab -e and sudo nano /etc/rc.local but unfortunately, neither of them work.  I'm using /home/pi/git/vthoang/cgminer/x1R606b.sh as my path. Any ideas and coding steps for a novice?  

Thank you

Hi, need some help. I've built my mini-farm into a Hydra Server III Case and it's been running very well. However, I got to it after work one day only to find a R606 disabled. When restarting, it only shows BM1387:03 to indicate only three chips are communicating and it disables again after a few seconds.

A Pi4 4GB was controlling this R606 (V5) plus x6 Newpacs (525MHz) over x2 GS USB hubs (x4 and x2). Different instances were being used, three in total.

A second Pi4 4GB was controlling another R606 (V7) and x5 Newpacs (525MHz) over x1 GS USB Hub and this has been running at WU100% for days. Again, two instances to split the devices.

Getting back to the poorly R606...I've killed the power and USB for a while but it only registers ':03' chips and doesn't fire up. It was running fine at 750MHz on V5 for days. Any ideas of how to recover this? I'm using a USB extension cable to plug a keyboard/mouse BT receiver in this Pi as the stack depth is fiddley to reach. Would this cable be an issue and enough to bring down a mighty R606?

Set up:

x2 Pi4 4GB
x3 GS USB Hubs
x2 R606
x11 Newpacs
x1 Hydra III Server Case
x3 120mm Bequiet High Speed Silent Wings 3 case intake fans with mesh
x4 80mm Bequiet Pure Wings 2 case extraction fans
R606 intake fans replaced with 80mm Bequiet Pure Wings 2 fans
x2 80mm Bequiet Pure Wings 2 fans added to both R606 on the extraction side
x3 Arctic Air USB Fans for each GS USB Hub
x1 Thermaltake x10 Fan Hub Controller/Splitter
x1 Newegg x4 Fan Speed Controller for intake fans
x1 DPS1200 PSU
x2 USB Thermometers for case IN/OUT temp monitoring
Lindy double shielded USB cables
All cable managed to death

Any help is appreciated in restoring the R606 back to the life please. I was at 3.4T and now down to 2.4T

Hi, quick question...apart from the obvious colour of green and black, are there any other notable differences between 2pac's?

Thanks very much for the info.  I've added a question 6 to my previous post...what do you think to adding the --btc-address xyz for soloing as per the readme?

Hi All

So after approximately 17hrs of stable running with no frequency plateau's or missing nonces, I'm looking like this below:

x1 R606 V7 750/750/750 1.017T WU100% Diff 10K R0 HW1807

x4 NewPac's 2.23A 500/500/500 450G WU100% Diff 2.5K R2500 HW261

x1 2Pac 2.05A 262/262/262 28G WU100% Diff 512 R0 HW0

All plumbed into one Pi4B-4GB, x1 GS hub for the sticks, Lindy gold/shielded USB cables, x3 instances (--usb 1:1,1:2 etc --widescreen --quiet) and a DPS 1200FB-1A PSU.

Questions:

1. Is this looking okay, have I missed anything and are there any tweaks to be made?

2. Do the HW faults matter with BM1387 chips as I've tuned the Newpac's to optimum Vcore vs freq? I'm averaging 3.8HW faults per hour per Newpac and 106HW per hour for the R606.

3. With ref to difficulty set in the command line, what should it be once you have established stable figures?  I've read x5 the total hashrate per device, start at 1, start at 32, leave blank and also a formula which I can't locate anymore.  What exactly is the diff, how does it effect me within solo.ckpool...any tips?

4. I plan to install everything above and more into a Hydra III server case with x3 120mm bequiet silent wings 3 or ac infinity fans drawing in and x4 80mm bequiet silent wings 2 or ac infinity fans pulling out.  The R606' will be set to accept this inward flow direction and I was wondering if removing the integral R606 fan would cause a heat issue?  The arctic fan it comes with is slightly louder than I would like so planning that the case fans would have the CFM to do it.  Has anyone installed their kit into a server case or modded the integral fan?  A portable case has got to be better than what my testing area looks like at present!

5. Is there a link to the older 4.10.0 version anywhere via linux?

6. From the README file..."SOLO MINING. Solo mining can be done efficiently as a single pool entry or a backup to any other pooled mining and it is recommended everyone have solo mining set up as their final backup in case all their other pools are DDoSed/down for the security of the network. To enable solo mining, one must be running a local bitcoind/bitcoin-qt or have one they have rpc access to. To do this, edit your bitcoind configuration file (bitcoin.conf) with the following extra lines, using your choice of username and password: rpcuser=username rpcpassword=password Restart bitcoind, then start cgminer, pointing to the bitcoind and choose a btc address with the following options, altering to suit their setup: cgminer -o http://localhost:8332 -u username -p password --btc-address 15qSxP1SQcUX3o4nhkfdbgyoWEFMomJ4rZ Note the http:// is mandatory for solo mining."  Does this mean my command line has this and the btc address twice but the second time without the worker?


Thanks for the advice and patience, I think I'm pretty much there and am ready to expand.

All sorted yesterday evening and I’m very pleased after some frustrating weeks.  I re-installed NOOBS, selected Raspbian Full (v3 Sep 19) and followed the details on pages 1-2.  I’m hashing nicely on a Pi3B+ with x1 R606 (V5/500MHz) and x4 Newpacs (500MHz) returning 1.2THs after 4hrs (x5 500/500/500 100%).  I’ll split devices when the Pi4 arrives, start expanding and testing the R606 to the speeds I was returning on Win7.

(1) Has anyone experience with these GPIO 3.5” or HDMI 7” screens, how they effect power draw and whether they suit cgminer at all?

(2) Can someone please re-link the piece on this forum that instructs on how to VPN via Windoze?

(3) Can anyone also re-link how to set the auto cgminer reboot after a given amount of time?  I’ll be running these 24/7 and need remote access.

Thanks for everyone’s replies and I’ve learnt something new

Ditto. Try using a different date release version of 4.11.1. I use 13 May and it works a treat on Win7.

My .sh file has this and permissions set to owner:


I've also added --usb :1 or --usb 1:12,1:13,1:14 1:15 and --gekko-newpac-freq x but nothing makes a difference. lsusb works as the devices are recognized.

Hello again folks

On Win7, there are different build date options within 4.11.1 which work differently with my R606 and Newpacs etc.  The question I have is what is the build version of the the link that is entered for Pi programming on page 28?  Is there only the one or are there differences such as the Win options?

If I wanted 4.10.0 to run 2Pacs, what would be the github link to that?

---

Hi

I've tried the instructions on page 28 time and time again and it just wont fire up cgminer 4.11.1 with any newpacs or the r606.  I get the date/time stamp and message "Started cgminer 4.11.1" then it freezes for approx 30 secs before saying its either the server, URL, check details or set up workers.  It then cycles between Pool 0 difficulty changed to 10000 and Pool 0 message: Failed auth

I've ordered a Pi4 but about to throw this Pi3B+ under a bus...what can I do next?  Please see above post where the Pi3B+ won't boot up with the command line given on page 28.  Is that the difference or what else can it be?

Thanks in advance and regards.

Can someone please quote the standard Raspbian OS cmdline.txt as I've messed up.  I can recall this but it's still not booting up to the GUI:

dwc_otg.lpm_enable=0 console=serial0,115200 console=tty1 root=PARTUUID=51df20e4-02 rootfstype=ext4 elevator=deadline fsck.repair=yes rootwait quiet splash plymouth.ignore-serial-consoles

I'm on a Pi3B+

Thanks

Just a quick one, at what frequency of time should the heat sinks be removed from 2Pac, Newpac and R606 miners and a fresh application of thermal paste be applied? That is if at all...

Also, I have ordered x3 Pi4s and already have x1 Pi3b+ coming for my setup in a Hydra VIII server case. The plan is to have x4 120mm bequiet silent wings 3 fans at each end (push/pull) running off a redundancy power design incase of failure. My current x2 R606's will have a Pi4 each unless that's deemed excessive and the 4-6 Newpac's from the third Pi4. The Pi3b+ is there if needed or can run the x12 dodgy Rockminer U10's. Depending on space, I would like to add R606' and increase any GS hub slots to Newpacs. How many R606 can be run off a Pi4?

Is adding a LCD screen via GPIO pins to each Pi an excessive power draw to the mining function or not? I would either VNC or hook one screen up to all micro HDMI's otherwise.

Thanks guys.

Hello, looks like great info. I’m getting some Pi3b+'s to run my setup of two R606, six Newpac’s, one 2Pac and twelve Rockminers. Is the guide above suitable for all these devices (forget the Chinese knock-offs for now) or are there slight differences in the command line coding for R606 compared the above for Newpac’s?

Cheers
