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?
I made a rotary input device that provides software-defined "virtual" detents and end-stops, implemented using a BLDC gimbal motor. It can dynamically switch from completely smooth unbounded rotation, to having detents with configurable spacing and strength and "end-stops" that spring back if you try to rotate past them.

It's got a round LCD on the front of the knob (wired and supported via the hollow shaft of the motor) and uses the flex of the PCB and strain gauge sensors (in the latest revision, simply SMD resistors whose resistance changes when stretched) to detect when the knob is pressed down.
It's open source hardware and software - https://github.com/scottbez1/smartknob
HN folks might appreciate that it communicates with host software on the computer via protobuf-encoded USB serial messages -- nanopb is awesome for embedded C protobuf support, and having the defined schema, autogenerated serialization code, and compile-time type safety is so much nicer than ArduinoJson or hand-written binary protocols!
I'd love to get it hooked up to some real software eventually (video editors or home-assistant control are my 2 main ideas), but it's really just been a fun project to tinker with and try out some new ideas and parts I've never used before.

Help with MT6701/SSI
I'm trying to design a smartknob based off Scottbez1's design (https://github.com/scottbez1/smartknob), but with a stripped down feature set. However I can't seem to get the magnetic sensor to work properly - it's an MT6701 connected to an ESP32 via SSI.

Is this rotary encoder an adafruit exclusive?
Thank you so, so much for finding it. Unfortunately on eBay its not cheaper and ali doesn't have it cheaper either. It looks like an out of production item, like when I wanted to make this https://github.com/scottbez1/smartknob and it was gone except when sparkfun got a few.
