A lot of backers have already started their first experiments with the StereoPi. In this update, we’ll answer the most popular questions, post an intro to the art of stereoscopic photography, announce our next experiments, and show off something we hacked especially for you.
Did you know stereoscopic photography has been around for more than a century? Just this past year, the Stereoscopic Society celebrated its 125th anniversary! In that time, they collected a huge repository of knowledge about high-quality stereoscopic photography. If you plan to take stereoscopic photos, our first article in a series of tips from the Stereoscopic Society and s3D photographers will be quite helpful.
Well, a lot of backers already received their orders and started their first experiments with the StereoPi. And, they have some questions. Let me answer two of the most popular questions.
At first glance, your reaction to StereoPi’s approach to power may be similar to your reaction to using Vim after a lifetime of Windows Notepad. It may shock untrained users, but keep calm - it is much easier than it looks.
From our Wiki:
Please let me dispel the myth: The micro USB on StereoPi is not for power as with the classic RaspberryPi.
Yes, we have a micro USB connector. It is intended for two things, needed by advanced users:
To power up your StereoPi properly, please use power cable provided. If you power your StereoPi over micro USB, the StereoPi will boot up, but on-board Ethernet and USB will be disabled.
We decided on this solution for power for two reasons:
To affix cameras to the camera mount plates, we recommend using 2 mm diameter screws. We suggested users choose the length and other parameters according to their particular setup, and so didn’t include any screws with our kits. Some users may choose very short (6-8 mm) screws, while others will want to add some special setup and use 20-30 mm screws.

If you have any questions, or just want to talk with other StereoPi users, we also have a forum: http://forum.stereopi.com
It’s a pity, but no popular video player has support for real-time, low-latency, stereoscopic video livestreams — they only support pre-recorded files. So, we took one of the most popular VR players, Skybox, and reverse-engineered it’s protocol. The result is we have a simple solution for StereoPi to livestream to Skybox. Next week, we’ll publish an article detailing this work, will give you all the code in a GitHub repository, and plan to contact the Skybox developers to discuss officially supporting this feature.
We need some help. We are looking for a programmer with experience creating native applications for Oculus Go. We plan to make a native, open source Oculus Go application that implements all the features in our current Android application. If you want to help us - please let us know in this Oculus thread on our forum.
The first production batch is out and the second has started, so we have some more time for new experiments. Our next step-by-step guides will cover two topics:
A Raspberry Pi-powered pocket projector
The first open source iCE40 FPGA development board designed for teachers and students
An open video development board in a PCI express form factor that supports overlaying content on encrypted video signals. Let's bring open video to the digital age!
