Before I buy a Prusa Core One, I decided to at least finish building the Anet AM8 BLV MGN12 printer and try it out. I have a shitton (read: all!) of the parts I need laying around for multiple years now.

This evening is presented to you by me taking apart the MGN12 carriages and cleaning them. I took a few noses of IPA and feel a bit dizzy right now. This work is complete shit and it's why I put off assembling the thing for so long. Totally looking forward of assembling them and cleaning the next three I need. I hate it.

Every time I am taking an ICE train, I have to think of this accident report where sheep derailed a train in a tunnel: https://www.jonroma.net/media/rail/accident/germany/014_Landrueckentunnel.pdf

They even modeled the sheep. Look at it!

Spoiler alert: In that specific circumstance with a speed of 210km/h, you need 10 sheep to derail the train.

FÜNFZIG MEGAPIXELS? Böööö!

I've been vibe-coding my staircase illumination protocol code, bootloader on the AVRs and a service client to talk to it. At some point Claude started adding a shitton of emojis and I just stuck with it.

I now have a fully working loader, I can tell the application to reset into loader mode, I can address individual lamps, it took me a while and I needed to fix a bunch of bugs, but everything works now.

I'd estimate this was 2-3 times faster than doing it without any help from AI.

Next I need to implement an animation player that can load LED animations from flash and cycle through them with interpolation between "key frames" using a central clock packet that the master will send out. Then I can preload animations and play them back later.

Then more work on my KNX device stack to fully integrate them into the house and make the motion sensors on the walls control them depending on the time of day and current brightness in the staircase.

Built the first of my staircase illumination boards. It's not super bright, but good enough for ambient lighting especially as I am going to have eight of them per story.
Today I vibe-coded a bit of Rust to make the blue board on the side control the color on the white lamp board. Things are working!

Yellow scope trace shows AC coupled VCC with the ASK/OOK modulated serial port data on top. The blue trace is the recovered serial port data using two peak detectors and a comparator.

Now this stuff just needs to work with longer cables in between and more lamps. And I need a proper protocol for bootloaders, animation storage and playback etc.
