Re: Walkthrough: Raspberry Pi/Block Erupter mining rig setup with autostart and vnc
I got two Pi boards myself, they are a lot of fun to mess around with. I have to ask the question though... why would one not use a 1 foot usb extension cords on each port of the hub to keep the Erupters farther apart? Hell could take a block Erupter shell off and vaccum seal all the PCBs and the exposed usb parts and just lay them in a few buckets of water, might melt the plastic but who knows! Iunno fun stuff 
Yes I thought about that (the extension lead thing) and I have heard of other people using these - I just decided it was more trouble than it's worth. The hubs nicely arrange the erupters for the fan to blow over them, I think it's important to have theit heatsinks facing upwards for the heat to convex (?) off of them. I have also fitted those raspberry pi heatsinks to the be chips (on the underside), and they heat up considerably so must be doing a good job. It's surprising effective a fan is at colling down those heatsinks. Having said that I don't have the fan running at night, and some days too (and it's warm here at present) and I haven't noticed any increas in Hardware errors by having the fans off, if anything it's slightly lower by a smidgen, but we're only talking 1.002% as opposed to 0.998% errors.
On the raspberry pi, I now have three - one for running Xbian to play films (http://youtu.be/G2-eUrGbl0I) from my bittorrent directories on my PC, this one for mining and another as kind of a testing one. Really versatile and keeping a lot of people very happy!
