@axel Nice, when it comes to art, bugs are sometimes welcomed and can lead to interesting discoveries.
The Archimedes was a really nice machine.
Back in those days, I was playing quite a bit with Mandelbrot sets on different machines.
Must have been around 1990, I had a 286 PC with a dual screen setup. One Hercules monitor would display a CLI like interface where I entered the coordinates to be drawn and see progress and one VGA display would render the set.
Coded that in C IIRC.
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
@designatednerd Welcome to the joy of 3D printing.
For the last 2 months, I've been trying out Cadova to design my 3D models. It's a Swift package providing a DSL so you can design using a declarative syntax similar to Swift UI.
The visual feedback loop is a bit long but I enjoy it very much.

I'll be publishing my models with the source code (after printing to validate they're more or less OK): https://github.com/ebariaux/3d-prints
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 ☹️
