And in order to test I've been using two browsers and just real live video of myself on both sides. There's an echo. And boy am I sick of looking at myself doing this lol.

So I wrote a script that launches a headless Chrome instance that joins a 100ms video room as a “bot user”, streams a provided media file (video + audio) as if it were a real webcam/microphone. It uses `ffmpeg` + `ffprobe` to scale the video to a max dimension, normalize FPS, and convert to:

.y4m (video for Chrome fake camera)

.wav (audio for fake mic)

You can see a test 45 min podcast with these bots on our staging server:

This has been a game changer for our internal testing. Now the bots take care of the two hosts and our team can join the room as viewers which has all sorts of other features to test.

You are welcome to try out the real site too. Prod is:

I looked at a bunch and kept running into the same issues - some had data that didn't look right, it was hard to use on smaller screen, others felt overly complicated for what I actually wanted to know: what's the crew doing, where is Orion, how fast is it going. The best one I found was issinfo.net/artemis, which inspired a lot of the design.

So I built my own. The part that was genuinely interesting to me was the data. Turns out anyone can query JPL's Horizons API for full ephemeris data on the Orion spacecraft -
