Backers Questions, New Batch, New Experiments, and One More Thing We Hacked for You

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.

The Art of Stereoscopic Photography

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.

Instructions are for wimps!

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.

Question 1: Power

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:

  1. Upload a Linux image to eMMC memory on eMMC-equipped Compute Modules
  2. Direct access to CM USB to enable USB gadget mode

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:

  1. In the nine years we’ve been integrating hardware into robots, copters, planes, and boats, we’ve learned to hate micro USB as a power delivery mechanism. In the end, we always just solder power lines to the contact points on the bottom of the classic Raspberry Pi boards. For the StereoPi, we wanted a robust connector for delivering power, one that won’t fail while your copter is four miles away or cause your drone to crash.
  2. We planned to keep direct USB access (available on Pi Zero and Pi A/A+ only) for advanced users, and also provide an option to use Ethernet and USB 3 on StereoPi. No Raspberry Pi models have such an option - this feature gives more freedom to DIY ninjas.

Question 2: Screws

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.

Wiki and Forum

Most information about StereoPi is collected in our Wiki: http://wiki.stereopi.com

If you have any questions, or just want to talk with other StereoPi users, we also have a forum: http://forum.stereopi.com

One More Thing We Hacked for You

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.

Help with Native Oculus Application

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.

Time for New Experiments

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:

  • How to create a phone-controlled stereoscopic camera with the StereoPi
  • How to use StereoPi as a lidar for your robot for obstacle avoidance

Stay tuned!

Product Choices

$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.

We are a small team of geeks who have been making remote-controlled things with livestreaming video since 2010. We've done everything from boats and planes, to robots, copters, and VR helmets. If we can't find the right tools for our projects, we build them ourselves.
