Building A Custom Optical Encoder For Rudder Position Sensing – Part 2
In Part 1, I introduced the problem of rudder position sensing for SCANS and explained why Gray code (and optical sensing) provides reliable absolute position encoding in the presence of mechanical imperfection and electrical noise. This second part examines the first part of the implementation: the translation of Gray code theory into manufacturable encoder disk.…

AI Meta-prompting for generating Q&A and SWOT Analysis of a Scientific Paper.
In this post I explore the potential use of AI meta-prompting as a technique to enhance question–answer analysis of scientific papers, focusing on how layered, self-referential prompts can guide large language models toward deeper, more critical engagement with complex academic texts. Rather than simply asking questions of the content, meta-prompts instruct the model in how…

AI’s Do Dream in Digital Media
Storytelling, an intrinsic human trait, has undergone numerous transformations since the dawn of civilization. From oral traditions around campfires to the written word, and eventually to the moving images of film and television, each evolution has expanded the horizon of how stories are conveyed and experienced. With the digital revolution, this evolutionary trajectory has taken…

What is a Raspberry Pi?
The Raspberry Pi series has been nothing short of a revolution in the world of computing. Initially designed to promote computer science education, these small single-board computers have transcended their educational roots to find applications in professional settings and even industrial uses. The Raspberry Pi Foundation has democratized access to computing, making it possible for…
