Use ramoops for logging under Linux (2021) (embear.ch)
Unfortunately, an embedded system is not free of crashes. To analyze and log such crashes it is useful to have a file system where we can store such information between reboots. One interface which is meant to do that is pstore and its current single implementation ramoops. Ramoops can store log messages inside a reserved memory area in RAM. The nice thing about RAM is, that it should almost always be available when the CPU is still running.

Pascal for Small Machines (hansotten.com)
This site is about my experience with the Wirth school of languages, based on the ideas and implementations of Prof Niklaus Wirth, Kenneth Bowles, Per Brinch Hansen, colleagues, and their students. And my experience with the various variants, from the P2 and P4 compilers originating in Zürich ETH, via UCSD Pascal P-System to the Borland compilers and Modula and Oberon systems. All applicable to small computers and device control.

RK3588 – Implementing a Vectorscope for processing video in real time (blogspot.com)
Following on from my previous post covering decoding and rendering HDMI input on the RK3588, I encountered a new requirement: implementing a real-time vectorscope to visualize chrominance information from the video stream. This proved to be a challenging task due to the need for efficient frame processing and rendering without impacting video playback performance.

The Dauug House - Dauug|36 minicomputer documentation (cs.wright.edu)
Dauug|36 is a 36-bit architecture for owner-built CPUs, controllers, and minicomputers. Only maker-scale assembly tools are necessary, so this architecture can be implemented anywhere on the planet without a semiconductor foundry. All you need is a bare circuit board, about 300 components, and some soldering practice.

Ashtf8/EinkPDA: An E-Ink PDA Device Using the ESP32 S3 (github.com/ashtf8)
This project is a PDA powered by an ESP32-S3 running a custom "OS" written in C++ using the Arduino IDE. This project utilizes an E-Ink and OLED screen in tandem to mitigate the refresh rate restrictions of an E-Ink panel while retaining the aesthetics and benefits of using E-Ink. This project is a work in progress and currently amounts to a simple GUI for navigating between apps, a text (.txt) file editor, and a basic file manager.
