I originally delved into the Raspberry Pi world in May of 2013. I had just taken an embedded systems class in my previous semester and was very interested to continue studying the topic in a simple way. The Raspberry Pi is a miniature single board computer that has input and output like a normal computer like USB, Ethernet, HDMI, etc. The thing that a Raspberry pi does not have is an enclosure. The computer is shipped with only the circuit board. This led me to design my own enclosure. I have come up with three designs I built around the different types of Raspberry Pi computers
I built my case out of the most flexible block building material on the planet, Legos. I Started with the idea of having accessible holes on every side for easy access to all the ports. I did not care about color in this case as I simply wanted to protect the pi. you cant see very well from the pictures but I have a window in front of the HDMI port and another open window on the other side for some of the other ports.
While this was a good build it is a glorious eyesore in that it has the classic random Lego block look but could use some more coordination. I wish I would have taken a couple more pictures to highlight the port slots.
Case for "Raspberry Pi 1 Model B Plus"
I regret having to take apart my first design as I think I could have still used it for the original model B. Anyway I took part of the way apart the original case and made improvements to accommodate the B plus case as it adds more ports so the layout of the board is different. It was subtle changes that I never took a picture of.
Not long after that I wanted to make some other improvements like choosing a color scheme, making it one block less long, and a little bit shorter. I did this by using flat pieces on the bottom as I was using full size bricks before. That made it much sleeker than the previous case. I also found a different style hinges I wanted to use.
I choose an all black finish because the red would go really well with it and I wanted to match the hinges themselves. I did away with the windows from the previous design because I could not find a window accommodating enough for the ports on this particular pi. The best looking feature on this design is the cut out of the USB ports and Ethernet port that had to be the whole width of the case. I added the overhangs above it for effect. I like the hinge in action and that it is less complicated but it is a bit flimsy.
Case for "Raspberry Pi 1 Model A Plus"
I created this case design as at the same time as I was improving upon the Model B+ case. The A+ board is a little smaller and things are moved around. I used the nice hinges from the original design except had it open from the other side. This took quite a bit of digging because all red flat pieces are hard to come by. I have a lot of Lego pieces and had to dig pretty hard to complete the enclosure. Another tough problem for all the builds was finding enough flat pieces so the door can lay flat. I was also digging for those. This design features all red bricks with a gray accent color. It is clean and the hinges work well. You can use all ports just as all my case designs so far. the hardest part of building these is finding the specific part, size, and color to fit together very much like a puzzle.
If I ever get the Raspberry Pi 2 Model B I will probably start on another case with some sort of design improvement.
