Decoding Creality's locked Klipper fork
The K2 Plus runs a Klipper fork with a 1.88 MB Cython binary at its core. What is inside it, how I read it without the source, and what the firmware does that the touchscreen does not admit.
Reverse-engineering the K2 Plus locked Klipper fork
Full system trace of the Creality K2 Plus: SoC, boot, IPC, the RS485 CFS bus, and the Cython-compiled Klipper modules - plus the techniques to read those modules without the source and rewrite them in Python.
Hijacking the display header to embed a Pi Zero inside an Ender 3 V2 Neo
Klipper on a Pi Zero 2W hidden inside the printer base, powered and serial-fed from the stock display header. Plus direct-drive, dual Z, custom heatbreaks, and the mods that followed once the host was clean.
Learning FreeCAD 1.x by designing hobby rockets
I learned FreeCAD 1.x by drawing parts for hobby rockets: nosecones, fin sections, motor mounts, recovery bays. The channel that taught me the workflow, and the parametric discipline that stuck around for everything …
Building an ESP32 quadcopter from a public project, and what flight control actually feels like
I forked okalachev/flix, printed a frame, and learned the IMU pipeline the slow way. Here is what every step between 'motor spins' and 'thing hovers' actually costs.
