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.

Stuttering in BLDC Motor
ODrive perhaps?
-
Can I use inverse Clark instead of SV PWM?
Well I dunno, maybe see how ODrive does it
-
How to select a DC motor/generator for pedal power?
Then maybe just hook everything to an Odrive and maybe add an Arduino or something to tell it what to do - although this also means you'll probably want an encoder at least on the pedalling motor to get accurate position/speed readings at low speed, since pedalling cadence is typically in the 60-90RPM range

Are Nema 23s Overkill?
If you want speed, use servomotors
- I need very precize DC motor speed controler. Any suggestions?
-
Bldc motor drive
This video may interest you, maybe also check this one and check out simpleFOC and/or ODrive
-
Output goes up instead of down when approaching setpoint. How can I fix this?
ODrive time?
-
Advice on motor control for a wave simulator.
Look at using some RC brushless motors driven from an ODrive board
-
How would you design this? Stepper vs servo? Pulleys?
You can probably replicate your own with appropriately sized RC brushless motors driven from ODrive boards. The boards can be linked together via CAN bus to communicate with your Arduino equipped with a CAN bus shield.

I love it when a guest isn't hesitant to voice their pet peeves in robotics
Thanks for the link! I know about simplefoc, the problem is the hardware. Simplefoc focuses on low wattage motors, e.g. a gimbal motor for a camera. For high wattage application, there's not much hardware available, and none that is affordable. There's odrive, which will set you back ~300$ just for the controller. Other than that, you'll have to go to traditional robotics companies.

Framework Laptop 16 Deep Dive – Enclosure
Let me introduce you to the PrintNC, a kind-of-high-end hobbyist CNC:
* https://wiki.printnc.info/en/home
* https://github.com/threedesigns/printNC
* Discord invite: https://discord.gg/RxzPna6 <-- extremely active CNC enthusiast discord
It's "kind of high end" as it uses steel beams (not aluminium) for rigidity, so it's capable of driving some really powerful gear... fairly cheaply. :)

makani - Makani was a project to develop a commercial-scale airborne wind turbine, culminating in a flight test of the Makani M600 off the coast of Norway. All Makani software has now been open-sourced. This repository contains the working Makani flight simulator, controller (autopilot), visualizer, and command center flight monitoring tools. Additionally, almost all avionics firmware is also included, albeit potentially not in a buildable state, due to the removal of some third-party proprietary code. We hope that this code will be inspirational and useful to the kite-based windpower and wider communities.
hoverboard-firmware-hack - New Hoverboard Firmware Hack. Now written from scratch and generally much better.
