About

First, I want to thank everyone for taking the time to look at my video, and for checking out what Im about below. Who am I and what am I doing and why? My name is Brian Garvey, I'm from the West of Ireland. Ive always had a keen interest in mechanical design. I have built up my own prototyping workshop which includes a drilling machine, lathe, a casting centre, and a cnc milling centre.

What is the Raspberry Slice? The Raspberry Slice is a unique and cool little enclosure I designed for use with the Raspberry pi computer.

 The pi is supplied in board form only, so an enclosure is needed to protect it, keep it safe, and make it look great too. I styled it on my favourite desert you may notice, and that is a slice of Raspberry Pie!

On the prototype, I chose to mount a d-sub connector on the side so that the user will have axcess to the header pins on the board. The d-sub connector is connected to the header with a short ribbon style cable. The ribbon, header socket connecter, and d-sub connector are supplied. The ribbon is crimped into the header socket connector, but not attached to the d-sub. This means the user must connect it to the d-sub. But, this has its plus sides as the user can then configure the socket however he or she likes.

You will need a soldering iron to do this, or you could also crimp the connections with a small pliers. It is also an easy task for someone that has, or can use an iron and only takes a few minutes once you figure out the configuration you would like. The d-sub connector is not necessary for the board to work, its just a nice added feature.

  I machined the prototype you see in the video from a rough hand sketch, and worked the rest as I went. The port positions are pretty correct. Ive just got an email from element13 saying I am now entitled to place my order for an actual working board, so thats cool as I can take some accurate measurements for the next steps.

  I did make a mock-up board to see if everything fits, and it does. The red shell is sprung open a little to locate over the audio connectors on the side of pcb. You then drop the shell and board into the base(which has had the end screwed on) and then pop the lid on with two more small screws. If you need to get at the board for any reason down the line, you just remove two screws, and off the lid comes. The board is still secure in the lower section. The prototype also features a grid of vent holes in the base. (not drilled all the way through on the prototype) It features light tubes from the on board leds bringing the light up to the lid, and easy to see. It features rubber non-slip feet.

  The case is really cool looking in real life, and I feel represents everything inside very well in one neat package. Some of the current case renderings I have seen are a little ''off the shelf'' looking, this one is tailor made. The production batch will stack, in that the rubber feet will locate into the pastry shapes on the lid. I think this could be a good idea should you own more than one, or if they ever get brought to school.

What I Need & What You Get I want to make a first batch of 100 of these cool little cases. The one above is painted machined Aluminium alloy, but to do a batch Ill have to make in plastic to keep the cost as low as I can.

This means for numbers near 100, Ill have to make proper aluminium tools to cast a pourable epoxy casting resin into. I think this is the best way for small numbers. The resin is great stuff, and mimics injection moulded parts in every way almost exactly. I can get it in the above prototype colours too.

Ill also have to buy the resins, and connectors. And loads of stick on feet too! I will have to buy some more cnc cutters to make the moulds. If the numbers run on more that 100, then my next option is to make a few moulds for epoxy casting. If they run to 1000, then I think Ill make an epoxy injection moulding tool. Modern epoxy is good enough to take 1000+ shots on a proper moulding machine.

If numbers exceed that, then Ill have to go to steel tooling. Steel tooling is big bucks though, so lets just start at the start and see how it goes! I will make a few changes to the design above if I do meet my funding goal, very small changes, and hardly noticeable. These changes are mainly draft angles so that I can pull the parts out of the moulds!

The Impact By supporting this project in whatever way you can you will be part of something big to come. I have great faith in both this little case, the Raspberry pi, the Raspberry pi foundation, and all that is to come based around it. For those that dont know what the raspberry pi is, it is a micro computer the size of a credit card. It runs linux. With a few simple steps, you can convert your tv into a pc with it, surf the net, browse, play games, go on facebook, and so on. Its possibly one of the most exciting devices since the mobile phone, and its all just around the corner!!!!!!

Go read about it now, its extremely great, and an extremely low price http://www.raspberrypi.org/ .....and then place an order for the coolest case around on here! Now, a bit of law... "Raspberry Pi is a trademark of the Raspberry Pi Foundation, this website, project, or Brian Garvey is not officially endorsed by RaspberryPi.org and has no affiliation with them' Brian Garvey, Law lesson over...!  

Other Ways You Can Help if you cant fund Some people just can’t contribute, but that doesn’t mean they can’t help: So what else can you do? Easy! Spread the word about the Raspberry Slice, its simple, just tweet about it, share on facebook, or even email it onto your friends. Everyone has someone that will just love the Raspberry Slice. 

A computer in a cool enclosure for under 100dollars?? TOTAL! I want to take a minute to give massive thanks to Liz, and Jack and all the team at the raspberry pi foundation for there insanely hard work over the last few weeks. None of this would be possible without them, so thanks again.

I will be making a charitable donation to the Raspberry Pi foundation should I reach my funding target (as promised Liz!)

Regards,
  Brian Garvey
