Cheap base for RaspberryPi

Sun Dec 29, 2013 2:01 pm

Is anyone making a cheap simple base for mounting RPi in.

I mean one for the experimenters that are always plugging camera's in and out and pushing wires onto GPIO pins.

I use pieces of cardboard with double sided tape but I'd like something like looks less Heath Robinson as they don't look impressive when showing off to non-geeks/teachers :)

Now - a half-Pibow does the job reasonably well but I can't afford the prices they charge in Sheffield :)

Any other solutions?

Half a ModMyPi case works well.

The Adafruit Pi Dish is not cheap, but it includes a full-size solderless breadboard, and might give you some ideas. If you have a local maker space with an acrylic laser-cutter, it's not hard to design something like this. Or even the right size piece of acrylic and a drill. Or wood.

What I'm looking for is a case supplier to make a half-case and sell it for half-price :)

Or someone to find some sort of existing plastic thing that would do the job and look OK :)

Hi, I use a prototype coloured acrylic board from Phenoptix that comes with a breadboad and two screw pins. It's designed for an Arduino or a Raspberry Pi. They are very versatile in my opinion and cheap.

Check them out here http://www.phenoptix.com/products/ardui ... g-hardware.

Happy I could help :)

I have two of them. One strapped to an Arduino Uno and the other is the base to a Pibow mostly built (6 layers) so I can stick a Piface or the Adafruit break out board on the GPIOs still.

You can't go wrong for the price they are.

But your still wrapping your RPi in another case - which is what I want - a cheap version of a 6 layer PiBow :)

I use the cheap pi-works acrylic cases (£1.75) and don't install the top cover:

yep - thats what I currently do but I find it awkward getting add-ons in and out all the time as you can't get a grip on opposite sides of a board since the left and back edges are hard against the sides.

(I'm always swapping boards in and out when working on my ScratchGPIO stuff)

And plugging single leads onto the pins is a bit tricky.

One way around this is to get an 26pin extension which raises the pins up but they are not cheap and then the add-on board isn't supported by that big capacitor on the right :)

My cut down PiBoW is just right (up to orange layer) so I basically just want something like that with same form factor

And a lot of boards (especially motor controller type boards ) require easy access to the boards to plug the motors and external battery power

I had one of my raspis in a shallow "tray" made of corrugated cardboard, folded and held together with ordinary white glue. (Though glue doesn't seem as cheap as it used to be!)

Some long bolts and nuts in the base in the right place, so the raspi can be put on the top, then bolted in with nylon washers to avoid any embarrassing short circuits.

(I have only Model As - these have extra holes where the network connector would be, so three bolts hold the raspberries down quite securely.)

Make it big & wide enough to hold a breadboard or backup battery pack or whatever you're tinkering with.

Also - at this time of year there seem to be lots of novelty biscuit tins & boxes in the local supermarket. All in the name of technology... :P :ugeek:

Base of a camdenboss case ? - that's open at the sides:

http://cpc.farnell.com/camdenboss/cbrpi ... dp/SC12864 - £3 @ cpc

or a cased model B I got from CPC just clips into a flat base without its top on:

It was the first answer, but I use half a mod-my-pi case.

If you don't mind what colour you get it's £3 (plus £1 postage, if you're UK). It's nicely shallow, everything top-side exposed, everything beneath protected, it's decent thickness ABS so you can hack it about a lot easier than anything in acrylic. When you don't have anything plugged in above the board the top just snaps on and off.

I can't find a case for £3 on ModMyPi - have you got a direct link?

That's very close to being an idea case for the job :)

But I can't get postage below £1-99 :(

How did you mange £1?

I have used several of the bottom-half-of-a-case solutions. My preference is the SB Components case - it's small and neat, the walls are quite low and the Pi clips securely into the base. And if you do use the top half, it's got apertures for just about everything including a nice wide one for the GPIO connector(s).

For experimental lash-ups, though - going back to simplesi's original question - I think it's hard to beat good old Blu-Tak:

That's what it quotes to me.
I went to https://www.modmypi.com/shop/GAMBLE-Mix ... ry-Pi-Case
I clicked 'add to bag'
I said I didn't want pink
I went to checkout and it offers me £0.99 for royal mail first class

Have you put other stuff in the order too?

I'd ended up with 2 cases in my basket :)

Ordered one now to see what they are like.
