A new Exploring Uncut post where I write about my progress with implementing a Mandelbrot set on an STM32 board: some surprises and learnings to get the FPU working with #EmbeddedSwift, learning about call-clobbered vs callee-saved registers and using ChatGPT not for vibe coding but as a debugging and learning tool.
Introduction This time, the focus is solely on providing an update on my exploration of getting a Mandelbrot set renderer running on an STM32F746G-DISCO board. I had hoped to also cover “The Egg Project” and some Home Assistant improvements I’ve been working on. However, there is already plenty to discuss here, and the other projects have been moving forward more slowly due to a collection of minor but frustrating issues, from ordering the wrong components, to chasing down unexpected sensor behavior, to tracking a Wi-Fi authentication failure caused by a simple case mismatch.
As I continue my cable management and desk organisation cruisade with the help of #3Dprinting, here is a model I did to attach my #UniFi network adapter on the monitor arm at the back of my screen.
The design was done in Swift using #Cadova. Source code is available at https://github.com/ebariaux/3d-prints
The model is also available on Makerworld: https://makerworld.com/en/models/2362606-unifi-5g-ethernet-adapter-support-for-monitor-arm
Last week I mentioned playing Forbidden Forest on a #Commodore SX-64.
Here is a bit of info about that game, coming from the « Commodore 64: a visual Commpendium » book, a kick-starter project I participated in a few years ago.
Flipping through those pages brings back some great memories.
Merry Christmas to those who celebrate and a wonderful day to everyone!
I have a fond memory of this #Commodore64 Christmas demo: https://youtu.be/TYJl1EzBs_4?t=40
In the shopping mall of my home town, there was a kind of general store and they had booth with a Commode SX-64. A student was demoing different software.
I must have been 12 or 13, and I probably spent the whole afternoon with her, watching this demo or playing Forbidden Forest.
First 3D print test of the egg.
Definitely not final but I could check the alignment of holes for attaching the boards and the camera hole.
And conclude that I need to pay more attention when I’m looking at a CAD drawing ☹️
Finally, after a big hiatus, here is a new Exploring Uncut post: Embedded Swift, Egg and Meta news.
Introduction I’ve had drafts of Exploring Uncut posts on my computer for months now. They contain bullet points of things I wanted to talk about, sometimes with additional notes, sometimes a draft of a few paragraphs. But as time went by, the potential post only became bigger and the time it would take me to finish it would only grow. So here’s a new post focusing on what I’m working on right now.
And a friend also asked about the book that can be seen in front of the NeXTcube in the picture I posted.
The book is "Enquire Within upon Everything", with a first edition in the early 19th century, it's meant to provide encyclopedic information on domestic life topics.
In 1980, Tim Berners-Lee named his precursor of the World Wide Web ENQUIRE, after this book.
