Raspberry PI 2
The highlighted comment was created in this revision.
There has now been a new version of the Pi released. I was going to get one as they are still dead cheap. I might run some rumble on it and see how it does. It apparently has a newer quad core CPU that runs at 900mhz and due to improved architecture has approximately 6x the power of the original Pi, plus the machine now has a gig of ram.
I'm going to give it a go and will report my findings (once I get one!)
If it all goes well I am in the process of getting my GA framework up and running where I will be able to run it on the PI2 and improve my bot (hopefully)!
6x a P2-300 is still pretty much crap by our standards. :-) But it sounds like a fun experiment, keep us posted!
It doesn't need to be lightning fast if you can leave it on all day every day running something. It only consumes around 4 watts compared to 500 for a desktop PC so its not going to break your bank to do so. I dunno if the power to wattage ratio is better than a desktop PC though! Are desktop PCs 100 times faster than a RP2? I would have thought not!
I can go to work, leave it running which is not what I would do with my desktop! :)
