#2Hey, author here. I used the system described in the link for indoor stabilization of a drone, plus precise landing, to support an automatic battery swap station project (have a video there). Worked pretty well, so I decided to open-source it in hopes this would help fellow hackers.
Let me know if you have any questions!

Awesome project, and especially awesome README file: good explanations and images!
If I read it right, a way to feed it position data is already integrated in the drone firmware, so you only have to send it the found coordinates and it uses them, correct?

Yep, I'm using Mavlink protocol (specifically ATT_POS_MOCAP message) to feed 3d position to the drone autopilot.

The hot-swappable drone battery video is cool enough to be its own Shown HN submission.
Would it be hard for the drone to be able to seamlessly switch between indoor/lighthouse tracking and outside/GPS tracking? How about the ability for the drone to orchestrate the battery swap autonomously with the charging unit? If you could add those two features you could produce a proof of concept video that would probably blow a lot of minds.

Thanks, that's nice to hear!
Seamless switching is definitely doable and shouldn't be hard, just need some time to implement. I'm using PX4 autopilot and it's very friendly for adding new functionality.
Orchestration is also close - in current demo both station and drone use Wifi to coordinate, so it's a matter of adding new logic.
Currently the most limiting resource for that project is my time :) I'd be happy if other people would want to join!

#7I've been mulling a installation work based on exploring video solids[1] around using cheap phone-VR mounts. This project is exactly what I need to find the viewers position in the video/space. Any cheaper way to do this without the Lighthouse devices?

Nice project!
There's a whole bunch of indoor positioning methods, having different precision/simplicity/cost profiles, so you might need to shop around. Probably cheapest and closest to my sensor is ultrasound sensors like http://www.marvelmind.com

This is awesome!
Curious what your thoughts are on this vs one of the official SteamVR tracking modules[1] which use the TS3633[2]? For $10 this is an awesome hack for off the shelf components. However, for $70 + Shipping you can pick up 10 of the tracking modules which filter out noise and do accurate envelope calculation.

I'm not familiar with the SteamVR tracking modules that you linked, however from the link:
> The CM1 contains all the circuitry necessary to convert SteamVR Tracking base station infrared light into a digital output that encodes the angle of the sensor from the base station.
That implies that it's not a full location tracking solution by itself (angle only). The data sheet[0] doesn't seem to shed any further (ahem) light. Maybe I'm wrong. And I'm certainly interested in learning more. Do you have more details on the SteamVR tracking system?
