Field Report: Minimalist case from mounting plate

by Dimitrios B

After my StereoPi was delivered, I needed a handy solution to get the cameras mounted and the StereoPi connected without fear of damaging the ribbon cables while experimenting. My first thought was to use a standard, generic case and add some high quality glass to get my 3D pictures and videos to an acceptable quality. However, on second thought, and not wanting to wait for a parts order to be delivered, I came up with an easier, cheaper, and faster solution: why not use the mounting plate that came with the StereoPi? Some 2 mm stand-offs, screws, four holes, and the short ribbon cables should do the trick.

I couldn’t find any information about the positions of the holes on the PCB, so I measured them with a caliper: 85 x 35 mm. The next step was drilling four 2.1 mm holes in the corners and countersinking all holes. The reason for the latter was that I wanted to use 2 mm countersunk Torx screws, to keep the surface even. The mounting plate is slightly asymmetrical in order not to bend the ribbon cables, so the whole plate must be mounted accordingly:

Then I added some hexagonal plastic stand-offs that I had in my workshop and gave it a try. Unfortunately, the camera cable next to the HDMI connector is in the way and it can’t be bent too much. After some quick research, I found some brass stand-offs that were smaller in diameter and round. So I was able to use these 12 mm and 20 mm long brass stand-offs with 8 mm long screws. To mount the cameras, I used 6 mm long screws, some washers and nuts, and that was that!

$69

StereoPi Slim Edition

Perfect for DIY ninjas and those wanting to embed StereoPi in a tight space. This board is the same as the standard edition, but without all the bulky connectors - the Ethernet RJ45 jack, GPIO header, and dual USB Type-A connector have not been populated. To use this board, you will need your own Raspberry Pi Compute Module, cameras, and camera ribbon cables. Two short power cables already included.


$89

StereoPi Standard Edition

The world of stereoscopic video awaits! This board is the ultimate interface between two cameras and a Raspberry Pi Compute Module. It comes with all the bells and whistles, including Ethernet, dual USB ports, GPIO header, microSD slot, HDMI output, and more. To use this board, you will need your own Raspberry Pi Compute Module, cameras, and camera ribbon cables. Two short power cables already included.


$125

StereoPi Starter Kit

This kit has everything you need to get started right away. The kit includes one StereoPi Standard Edition board, two V1 cameras (w/ ~20 cm ribbon cables), one Raspberry Pi Compute Module 3 + Lite, and everything in the StereoPi Accessories Kit (two short ribbon cables, one USB power cable, two power cables, one V1/V2 dual-camera mounting plate, and one wide-angle dual-camera mounting plate). We've also included a microSD card pre-imaged with Raspbian and all the stereoscopic video and image demos you see on this project page.


$199

StereoPi Deluxe Kit

This kit includes everything in the StereoPi Starter Kit and adds two wide-angle (160°) cameras (w/ ~20 cm ribbon cables). With this kit, you'll be able to run all of the demos shown on this project page and start experimenting on your own. You will reign supreme over your stereoscopic domain.
