Unfortunately thats the way the education system is. It cant prepare you for the future needs of our society.

Yeah, check out Dave, often good info and reviews, mainly focus is on EE and associated equipment, but always entertainingly overenthusiasticwww.youtube.com/user/eevblog
Thanks for the link, Ill definitely take a look

I am actually in the process of building a 48 node RPi cluster for testing network equipment. We deal with high availability servers so having a switch fail is to be avoided at all costs. Even brand new switches can fail out of the box. The idea is to hook up 48 RPi to the switch and max the links with file transfers of various sizes for a month before putting them into production. This should hopefully weed out most of the bad apples.
As a proof of concept I first built a 6 RPi cluster. For mounting I used 4-40 threaded rod with nuts to space them apart. The threaded rod cost me 1 dollar (US) a piece at a hobby shop, and the nuts cost me 3 dollars (US) for 50. To power it I am using 1.5 foot USB cables that I got off amazon for 1 dollar (US) a piece and for right now dual port, ipod wall chargers that I got for 6 dollars (US) a piece.
One thing to keep in mind when powering your RPi is if the RPi does not get enough current it can cause the RPi's internal USB hub to mess up. This results in the NIC messing up. I ran into this with the ipod wall charger. One of the ports has issues maintaining correct power.
In my final design I plan on getting two 5V 40A bench power supplies and building some sort of power distribution system. This should get rid of the chance of under powering the RPi. The problem I am running into is finding a good way to handle distributing it to the 48 RPi's and still keeping the wiring from becoming a rats nest. I am probably going to keep with using the mini USB cables and find some way to wire 48 USB ports to the two power supplies.
When all is said and done I plan on writing up a nice write up on it somewhere and link to it here.
Sounds link a really neat way to test your equipment. For my power, im using a 500W computer PSU which has more than enough amperage on its lines for all my Pis, Im also adding a 1A fuse on each channel to the Pis to avoid excess current draw. 1A is about the max it can handle according to my research. Looking forward to reading your report.

Thankyou good sire, I was aiming for ridiculous
