Re: Is MAGI mining profitable?

Hi , Just reading through the post people seem to me getting around 11 khash/s using a PI3 I seem to get 1-4! What am I doing wrong? I'm using a Raspberry PI 3 Model B Mining Magi on MinerClaim. Is there something I need to tweek? What factors effect hashrate? Any advice would be gratefully receive...

Re: Is MAGI mining profitable?

Pi3 gives me 11 khash/s don't have an energy meter attached to it so not 100% sure of it's usage. How do you achieve 11 Kash/s? I've just compiled it, and it runs @ 4.4Khash (4*1.1). Did you use special compile options? Overclocking? Thanks Nothing special other than using the 64bit OS https://gith...

Re: Is MAGI mining profitable?

quick 'n' dirty calculations : the Pi3 uses 1kw/h in 10 days @ 11.0khash/s 4 x zero uses 1kw/h in 8 days @ 2..8khash/s So with the higher hash rate of 11khash/s the pi3 is the more efficient choice. Will have a better write up at the weekend, with the amount of coin generated per device, that will g...

Re: Is MAGI mining profitable?

thanks, what are your electricity costs per kwh? Also, because of the more powerful? cpu and more ram, would the pi3 have better or worse hash rate/electricity usage? I'm paying £0.16($0.21) per KW/h Each coin is worth between $0.21 - $0.25. I'm currently doing tests with the 4 zeros to see how muc...

I'm currently mining Magi using 4 zeros and a pi3 At the moment It's NOT profitable by any means, but things can change and it's not adding a huge amount to my electricity bill. it's a nice hobby. Quick stats on my 4 zeros : 2 x rpi0w = 0.71 khash/s 2 x rpi0 = 0.69 khash/s In total they are pulling ...

Re: Update cluster via script

If they are all named in a similar way you could use something like this:

Code: Select all

for I in 1..4 ; do echo -n "RPi-$I:";ssh pi@RPi-$I.local [[enter command here]];done
I use it with my ClusterHat, you can easily use it to run a bash script for each device in turn.

Re: Request for SSH Enabled Images

Best suggestion would be to "build" your own image.

Get latest image and install, set it to how you require it and use that as a baseline.

Then just dd the whole card to an img file stored locally.

If you ever need a new image just us the local file and dd that over the card as per your script.

It should just be a case of mounting the PiDrive at a suitable location for the software to save images to. From a quick look the program stores captured media in the following location : /home/pi/pikrellcam/media/ Easy way would be to mount the PiDrive at boot (in the /etcf/fstab file) and then edi...
