Asking the Fediverse hive... Do I know someone in/around Nürnberg who could lend me an old-school cathode tube (CRT) TV from Thursday to Saturday next week? It needs composite video (or SCART) input.

at the risk of pulling the "someone is wrong on the internet" move, AFAIK FF uses classic encoder-decoder neural MT. this is the precursor of LLMs, but meaningfully different. the models are orders of magnitude smaller, and they are trained on orders of magnitude smaller, "labeled" datasets (sentence pairs in a language pair, not boundless unstructured text).

I'm low-key considering a digital detox experiment: specifically, not carrying an internet-connected smartphone around during the day.
Does anyone have experience with this? What was easy, what was hard? What were the surprises?
My motivation is twofold: mental health; and to test how realistic it is to remove captive tech from one's life.

Bogdan, who is sadly not on Mastodon, built a web server from a disposed vape.
On the one hand, what has the world come to, treating 32-bit processors faster than our youth's computers as disposable...
OTOH, the sheer amount of cool we can do by just repurposing the trash shat out by rampant consumerism!

LLMs are like the talking computers from Star Trek actually happened, but it's the wrong series and instead of Starfleet they were built on Coruscant and are run by Palpatine's cronies.

Pinging the electronics hive mind...
A new Shenzhen-based electronics parts seller called LCSC has started coming up in my searches. Their shipment fees are below Digikey and Mouser (to Germany) and they seem to have the chips that my go-to native German seller (Reichelt) notoriously lacks.
What is your experience with LCSC?

Here's the hand-drawn sketch I made four years ago, and the initial frankenstein build that I just dusted off.
The idea is a forever-running engine powered by a small solar panel. It's an arsthetic object like a light mill, with no practical purpose.
It's like a last-ditch love letter to the idea of sustainable tech with solar power. And to open hardware and reclaiming tech from sterile white enclosures sealed off from us by consumerism.

Here it is running the 2D water simulation from earlier. After some more fighting with PlatformIO, I got the FPU working too. It's sweet and fast!

All mysteries resolved! It was an extremely embarrassing oversight: my code did not initalize the GPIO pins for CS, DC and RES. Along the way I also borrowed the init sequence from U8g2.
This board is now also fully functional! The creative phase can begin - it's coding all the way now.

Much additional soldering has happened, with one near-fatal mistake, which the circuit miraculously survived. I have working USB! But for today I've hit a roadblock: the display won't display.
Worst (but most likely) option is I got the order of the 24 pins wrong. Next is, the library I'm using sends an incomplete init sequence. I may even be using SPI wrong, though this is improbable.
The investigation will continue tomorrow with more tooling.

I am most concerned about soldering the USB and FFC connectors. But through a combination of inspired searching and luck, I discovered these two modules! They'll let me plug into my board and verify connections one by one, using the test pads where needed, and check that I haven't shorted neighboring pads.
These are my recent learnings :) Let's see how they'll hold up in practice.
If you have any experiences or suggestions to share, please don't hold back!

This is by far the most ambitious board I've attempted yet.
- It's tiny! And packed. All SMD morsels.
- I'm wary of the many-legged beasts: a USB-C socket, 24-pin FFC cable connector, LQFP64 chip
- It has a 3.3V -> 12V boost converter for an Oled display; I've never built this kind of circuit
- I've discovered pogo pins! That's how the programmer will connect (pads at bottom right)
- Added a bunch of test pads (top) so I can verify sub-circuits while building up the board

Is this the time to launch a new botsinspace, based not on Mastodon code but something like #fedify, or even RSS Parrot's minimal Go codebase? A specialized service might be more affordable to operate?
But expertise is clearly needed to detect and block bandwidth-hungry scrapers and other bandits... This needs to be a team effort.
Thoughts, anyone?

In the VW models I last drove (e-Golf, ID.3/4), temperature and fan have no physical knobs. It's all integrated into the shitty touchscreen UI. Usually this "app" is inaccessible for minutes after starting a car because it hasn't "initialized" yet.
I hate to see generations of engineering culture and a whole manufacturing ecosystem go down, but fuck it, VW: you had this coming.
Not to mention the emissions cheating, remember?

This whole week I've been frantically trying to make cyanotype prints of a series of plots on tracing paper. I dare say it's a finicky technique! I've got individual pieces that I'm happy with, but getting to a consistent series of 4 has so far been elusive.
But I'm extremely pleased with the Bathroom Window Caustics™ effect that I discovered somewhat by coincidence.

Spent the evening defining a more interesting spiral geometry. I'm loving the soft, flow-y, and dream-like output of this algorithm.
I am feeling for a way forward towards a longer-form piece with a compelling amount of variety. Lighting and composition are very sensitive, so I expect a lot of curation will be needed.

It's been 1.5 years since I first started obsessing over Piter Pasma's rayhatching algorithm. I recently dusted off my own solution and adapted it for ThreeJS mesh geometries.
Here's a cloth getting hatched!
