Here's a refined version with improved grammar while keeping the original tone and language:
This project is a custom controller built to replace the original freezer controller that stopped working. It operates by reading the 10K NTC in the fridge and controlling the compressor relay.
Note: this controller does not replace the built-in compressor relay; instead, it uses an additional relay to control it.
The video is a dev log that walks through the process and the challenges I faced along the way.
This project is what inspired my previous blog post about writing data to SD cards without a filesystem.
The design and source files for the project can be found on my Github.
