I was inspired to this project after I saw a video from the Youtuber Tinkernut who made a tutorial about how to configure a simple Rasperry Pi Cluster on the software site. This tutorial focused my mind on the topic of Cluster PCs, and long story short: I now own 2 Raspberry Pi B and one Raspberry Pi B+.
After a bit of experimenting and scratching on the surface of cluster computing I encountered the problem that three pilled up Rasperry Pi's maybe aren't the best way to operate them so I decided that I need a case for them which also takes care about the networking and power distribution for all Pi's.
The cluster project sadly is on hold because one of the Raspberry Pi B is dead, and replacements are hard to find. Also a cluster nowadays is more use full with Raspberry Pi rev. 2 's that's why I end this project and plan a similar new one with the new Pi's and another completely different case.
But for now this project belongs into the HackADay Fail category.
Lately I finished the work on the power cables, connected everything and temporarely secured everything with scotch tape.
The circuitry is still pretty easy done because all black wires go to the ground pin on the pi's gpio and the red ones to one of the 5V pin's. I think I'm going to add a protective diode a fuse and a capacitor to smooth out any voltage variance.
As you can see, I haven't progressed in finnishing the case. I've discarded the idea of a triangular shape which was sort of problematic and moved to a standart box shape but to finish this, I have to buy more metal and return to the workshop.
I got all three Pi's mounted on the base plate drilled the holes for most of the power cables. Whats waisting my time right now is the fact that I don't got all the tools I need to work with metal but in the next 24 to 48 hours I should be able to drill the last holes and bend everything into shape. If all that is done I can focus on the wiring and the power setup of the case.
