Topic: From Laptop to Minepeon (Read 873 times)
Similar experience here. I switched to an atom based netbook to run my USB farm and saw on the order of 5% improvement in total hash rate. Side benefit is that it also runs the stratum proxy for my blades just fine as well, which the Pi was really struggling with. Stability seems to be better also. Running one of those 49-port BE hubs here.
The Pi's weakness is it does not cope with usb will. You need a 5v 1a psu for the Pi. The Pi uses .500Ma for the cpu and .170Ma for each usb port. What ever hub you use must have a psu that can supply a minimum of .500Ma to each hub port that is being used.
You should have a dedicated psu for the Pi, a dedicated psu for the hub. Plug everything into the hub and then the hub to the Pi. A wireless dongle can draw over .750Ma. I never achieved good results using a wireless dongle and the Pi, much better speeds with cat5 cable.
I'm running 9 hubs with 100 erupters plus 2 Blades off the Pi and getting 53+Ghs, Minepeon under Arch & bfgminer.

Hi,
i am using the Pi with my BFL 25GH/s Miner and there is no difference in speed. I did not use the MinePeon, i installed a Arch Linux as described in the BFL forum.

Let me know your thoughts.
Plug it back in to the laptop.
I'm running about 70GH locally, and the Pi can't cope (ASICMiner Cube, 2x ASICMiner Blades, 2x Jalapeno and a few other USB miners).
The Pi has a fit, so I'm now running off a Celeron NUC running Ubuntu 13.04 Server. It doesn't break a sweat, and only uses 11W of power.
I'm having a good time playing with minepeon. However, It looks like I'm getting 10ghs less on my bfl single on the pi then i am just plugging it into the current computer (windows) and running easyminer. I've done some very basic tuning for moderate overclocking, made the FS noatime, reduced vm.swappiness to zero. Running with bgfminer. Any hints from the experienced miners out there?
Stats:
External Powered Belkin USB HUB
BFL Single 50/ghs
External Wireless dongle
Rasp pi model 2
Everything goes into the external powered USB (even the pi) - takes on wall socket for the powered hub
The minor is plugged into the wall.
2 outlets.
Let me know your thoughts.
