Simple Pi Rack

Here is my solution for racking Raspberry Pis, using a block of plyboard
and the audio and video jacks as mounts. This allows simple plugging in and out.

I used a Netgear 8 port switch, and a Plugable USB 3.0 7-Port Hub for power
(which works as long as you don't intent to add further USB devices).

Hope it might be useful to others!

NIce and neat. Any chance of a pic without the Pi's plugged in.

Cool Beans !!!!!

wow, Set them up to do distebuted computing, and youve got yourself the most amazing pi computer ever

nice

tidy.

Looks great
Love it.

It appeals to my sense of tidiness and completeness. Well done.

Pictures of the board without the Pis, particularly for Jb2cool.

The back is not so neat - but, no one will see that:

Tools used, and a little PVA glue, the drill bits are 9mm and 11mm for audio and video, respectively.

A vertical bench drill, would have helped keep the holes true, but I could only use what was at my
disposal.

The biggest problem overall, was obtaining 7 UTP and USB cables all the same length, I ordered
20cm, but didn't always get it.

Thanks, that is such a nice idea.

nice simple idea, I like it

Niceley done. So clean compared to some of the other multi-pi holders.

Probably a dumb question, but what is the advantage of having so many Raspberry Pi's? I've seen lots of pictures of people that have hooked up one (or more) pi to another, but I haven't been able to find a reason to it.

Could be anything from clustered computing to hosting a different service (website, FTP, etc.) on each one. Even something like a classroom environment where each student SSHes to a different Pi.

I have three Pi's all neatly stacked (in identical, but different coloured cases).

One is an HTTP/IMAP/SMTP/FTP/SSH/stuff server, one is an IRC server, and one is my 'development' unit where I test Baked Raspberry Pi Mod and other things (that one gets re-imaged every few days while I'm testing modules and installing/uninstalling packages and things.

I legitimately still want:

One dedicated to being an IP PBX (Asterisk), one being an XBMC media center, and maybe another one or two for various things.

The low power use of these things is incredible, as is the small size, the fact they are totally silent, and because they are so cheap, it is very viable to have one per task (or set of tasks).

Previously I ran a Sempron 3000+ laptop as my 'server' doing everything, and it had fan noise, and used more power than 10x Raspberry Pi's, and if I borked the system, it took down EVERYTHING. (It wasn't able to run virtualisation to suit my needs).

Love the Pi.

Okay, that makes sense. I was overthinking it.
Thanks for explaining it.

Personally, the Pis are allowing me to experiment with integrating and configurating
a stack of Open Source Application Lifecycle Management (ALM) tools, one instance per
server, in much the same way as done in large industrial scale installations, using
much the same operating systems and toolsets, but at a minute fraction of the costs
in terms of hardware, power, space and other overheads. And, I'm completely at liberty
to pursue the avenues of my choice, without any of the influences I might normally need
to consider.

The Pi is indeed a great learning tool!

I don't have much space, so one of the first challenges was how to neatly group them, after
a number of failed attempts I struct on this one, which neatly fits on half a shelf of my Billy
bookcase, and thought it might just save others some agony.

This is perfect! Been looking for a solution to power 3 raspberry pi's (using http://www.amazon.com/gp/product/B00BGUE4W8).

The Simple Pi Rack has been redesigned, the network switch and USB powered hub are now underneath, and the Pis are mounted on the HDMI connector. It all now fits neatly on a desk beside other kit, and into a shoe-box (along with PSUs and cables), for easy transporation, without any need for dismantling. See the Simple Pi Rack Mk II at:

You mentioned that you used audio and video jack as mount. But I still did not understand how you did fastness to Pi. Could you show more details? Thanks in advance.

Apologies for taking so long to reply. I think you probably mean fasten, so perhaps the following picture will help:

Just slot them in to fasten!

However, I now find it simpler and sturdier to use the HDMI connector. It helps reduce the height, makes it easier to get access to the SD card and USB sockets without cables getting in the way, and the edge of the card now rests snugly on the wooden plate:

Using the HDMI socket
