That's how i did it at 1st, it's pretty cool because you get a display but all the parts are expensive and what the picture doesn't show is that the hub used is upside down under that pi; right-side up and all the miners are facing the table, which isn't ideal for heat. Now i use MinePeon which uses the web to interface with your miners, it's WAY easier to use.
This tutorial helped a lot: http://www.daveconroy.com/beginners-guide-to-turn-your-raspberry-pi-into-an-affordable-bitcoin-mining-rig/
And here's where you can download minepeon (i use the beta 0.2.4):
http://mineforeman.com/minepeon/If you already know how to ssh to your pi and burn an image using Win32DiskImager then you are ready to rock my friend! Otherwise you might have to spend some time with it. Only downside to that is you won't get a cool little pi-top display, though i'm sure enough digging in google could prove me wrong. If you want to get started with antminers :
http://minepeon.com/forums/viewtopic.php?f=4&t=1213&start=30that forum had all the instructions to get mine going at 1950MH/s per miner and more. I only have 1 now but am waiting on more in the mail.I bought it through Jones Gear at amazon who might have cranked them up before shipping or the setup did so. It works with the ASICMINERs i have in the same powered hub.
Also make sure you're using a POWERED hub, sticking either miner directly into the pi will do nothing. You need 0.5A for each miner at least, that's the same for antminers and asicminers.
SO, if you want a project and want to solder some stuff, go with adafruit, if you want to get to mining quicker or with antminers (just because i don't know how to get them to work with the adafruit method) use minpeon. I hope i covered enough to get you up and mining if not ask some more questions and i'll be by here occasionally to help out. Happy Mining!
