Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Ask HN: What's the coolest physical thing you've made?
A class-A, solid state, single ended headphone amplifier, not my design, however turned out to be nice sounding: https://github.com/Wanderingidea/Formula3HP-headphone-amplif...

Ask HN: What's the coolest physical thing you've made?
A thrust vectoring rocket! It was my sanity project during the pandemic. Flew many times and even flew two stages with slight software mods:

How to Start a Rocket Engine
BPS Space is what got me into building my own thrust vectoring rocket during COVID lockdowns.

It was super fun to bring together lots of different disciplines and skills. 3D printing, software, soldering, circuit design, simulation etc.
Ultimately, I got so obsessed with it I got burned out and had to take a break for a bit but came back fresh and finished it. Did a few flights over the year with more and more interesting things culminating in a dual stage flight. I've still got the rocket ready to go anytime. Just gotta wait for the weather to clear up.

Exploring the software that flies SpaceX rockets and starships
On the topic of rocket flight computers, here's a link to an FC I built last year for my model rocket. It does thrust vectoring and some rudimentary navigation. The control loops on this thing run at 200hz though. It's got a state machine for knowing what to do at each stage of flight as well.

Show HN: Rocket Thrust Vectoring Control Simulator in the Browser
https://github.com/polishdude20/CygnusX1
This uses a simple PID controller to bring the rocket to any angle you want from an initial angle. There's a lot of settings that can be changed and variables to play around with. Right now, It's configured to do sort of what starlink does during it's flip maneuver.
Anyways just thought I'd share!
