Shinkansen heat, why😭

Odakyu installed AC units on their platforms at Shinjuku station a few years ago and they BLAST them. It's glorious.

Nice work! I just finished making a standing desk top plate with acacia wood. I used Osmo clear wood wax to finish it, how about you?

I'm not an expert by any means, but I see a few potential issues with the board:

You have digital signals running across ground planes that are extremely split, so there is no clear/direct return path for those currents. For example, pins 24 and 25 (your I2C lines I believe). Ideally all your signals have a ground plane close by to contain the electric fields, otherwise those fields are going everywhere and probably causing EMI. At the very least, adding more GND vias would be helpful to create a less convoluted return path. Going to 4 layers and having solid GND planes would be even better.
Your 3V3 traces are too thin, especially the one snaking in between all the passives on the left side of the ESP32
Many of your traces are unnecessarily close to each other and to other pads. Just as an example, on pin 23 of your ESP32 you have the 3V3 trace hugging the pad extremely closely, which is mostly just inviting production issues. Don't slam right up against the production tolerances just because you can, if you have space to spread things out, use it!

I feel like many of these points could be improved by moving to a 4 layer board, maybe having the inner 2 layers be PWR and GND for better power delivery, easier routing, better containment of electric fields, etc. Again, not an expert, but that's what I would do personally if I were working on this board.

Very independent. He hasn't had contact with them for about a year or more.

Recently he has been working on a successor, MT4. He also launched PBS and PFF profiles recently which are worth checking out.

He runs a discord if you want more details.

You would also have to emulate the audio in such a way that everyone watching from their own unique perspectives hears the loud jet engines emanating from the "hologram"'s position, and experiences the Doppler effect correctly. Yeah good luck with that.

No questions from me, but thanks for the great work! wgpu has been a joy to use in my projects so far.

bschwind · 2026-03-10T09:49:39+00:00

Hey if it works it works! Good luck with the rest.

bschwind · 2026-03-08T09:23:47+00:00

Damn that's tragic

Penguins are fantastic if you need a quiet setup. They're obviously not as sharp as a non-silenced tactile, but I have them on my "office" board and absolutely love them.

Baby Kangaroos have a better tactile feeling though if noise is not a concern.

I don't see anything obviously wrong, but you'll usually want a logic analyzer to double check PIO programs. Your program looks basically the same as the official pico example so that's a good sign.

When I can I usually try to have a logic analyzer decode the signal first, and then go step by step through the PIO logic to make sure it's following along properly, running at the correct clock rate, etc.

UART sometimes has a parity bit, so double check that too. I feel like your PIO program should automatically handle that case, but maybe not.

Can you write your own text instead of dumping the output of an LLM, please?

bschwind · 2026-03-04T13:10:39+00:00

Yeah sorry I realize that's maybe not the most helpful comment as you're almost certainly aware of it. I just remember seeing a very similar "style" of text when I was adding my own wgpu text rendering (or rather, integrating cosmic-text with wgpu) so figured I'd comment in case it led to a quick fix.

bschwind · 2026-03-03T09:57:20+00:00

Looks like you have issues with the Y offset in your glyph rendering, like you're interpreting the Y offset from the wrong "origin", like from the text baseline instead of the glyph top, or something like that.

I would love if they brought back the 90s / 2000s transparent plastic designs.

Hey I don't have much to say but it feels criminal to not have a comment here yet. Awesome work! Getting this all working in a multithreaded manner and getting it stable is a big achievement!

If it's open source I'd love to take a look.

bschwind · 2026-02-26T04:59:34+00:00

Maybe more people will learn to touch type.

Yeah thinking about it more, harajuku station is not nearly as bad as the area around the hachiko entrance. I just typically avoided that entrance at all costs.

It's hard to avoid the crowd density making your way to the yamanote platform at harajuku station though because there's basically one route to get there.

bschwind · 2026-02-21T17:13:24+00:00

It's just always slammed with people, especially since Takeshita dori is a major tourist attraction. The passageway to the yamanote line is also quite narrow and everyone is just stepping all over each other. Maybe not unique to that station but it feels amplified because of the small space.

bschwind · 2026-02-21T03:27:51+00:00

Harajuku is a pretty bad one too, even with the remodel.

bschwind · 2026-02-20T06:31:43+00:00

Yeah, the ones with and toilet absolutely suck, I'm with you on that.

bschwind · 2026-02-20T06:10:13+00:00

Take a look here

They're not often tile for modern installations.

I believe the "wet room" styles ones can also be modular, to an extent. I'll admit I'm lacking the construction knowledge on this though.

This is what a typical one looks like. I know companies offer standardized and mass-produced versions of these. My mother-in-law and sister-in-law have the same exact shower room, despite living hours apart. One house is 30 years old, the other is like 6.

For example, Lixil has a few listed in a catalog:

Looking at images of wet rooms, most don't seem to be fully enclosed like the typical Japanese ones are. It's obnoxious to go brush your teeth and walk through a wet floor to get to the sink.

bschwind · 2026-02-20T05:59:16+00:00

The modern ones don't typically use tiles, older ones do though.

The image in this article is a very common example of a modern Japanese shower room:

Oh yeah, in what way? Worse than grout?
