All 4 copper layers on a Jumperless V5

For reference, these are the layers on a Jumperless. It's weird that it looks only slightly more complicated even though there's orders of magnitude more shit going on.

Wait, do they make conductive tattoo ink yet? That would be so rad

That's what I was thinking when I had to do the walk of shame switching to a 4 layer board.

It's crazy how much routing it took to make this silly little SMD breakout. Like, it feels wrong somehow.

My pillow guy selling energy drinks

Son of a bitch, My Pillow guy's selling energy drinks called Rev 7 (the latest Jumperless hardware revision is called V5 Rev 7.)

Oh yeah this is a fork of Viper IDE. I just didn't want the little info bubbles covering the Connect Device button and other silly nitpicks like that

I need to make some setup for VSCode / mpremote because I agree it's much nicer

JumperIDE MicroPython Web IDE for Jumperless boards. Connect, edit, run, and save code to your device.

It's not Jumperless-specific, so it'll work with any board running #Micropython. It really makes me never want to go back to using Thonny or whatever.

ide.jumperless.org

I forked Viper IDE to fix a few things that bugged me, but of course I had to be super extra about it and make clicking any function bring up the docs, and threw in a little OLED bitmap editor for good measure.

So now it's Jumper IDE and it is friggin' rad

Yeast feels like nature throwing us a lay up as an apology for the supply chain of honey

Yeah this is like the one time I feel like I've outclassed both grass-touching humans and LLMs simultaneously.

The most delicious loaf of sourdough bread ever made (by me)

Sourdough, motherfuckers!

The sudden switch from "hey it's an edible wheat slurry" to "this is the most delicious thing I've ever eaten" must've killed the first like five ancient people to invent bread making.

I am the intermediate mass black hole at the center of the Maker Hardware Workshop globular cluster.

Snake isn't actually the point here, it was just a debug/test thing for the new graphic overlay system that I got a bit carried away on.

I know I did like, a full-on Doom port a while back, but for some reason playing Snake on top of a running circuit is equally exciting.

looking down the tube of a 45º infinity mirror

Here's what it looks like from the side

@alpenglow.bsky.social got me wondering if it's possible to do an infinity mirror with a 45º bend in it. Turns out it totally is.

(There were much easier ways to validate this that don't involve an overnight render)

This is what happens when decide to live on a Costco rotisserie chicken and the croissants run out first.

I hope next time it's the other way around and I start farming chickens in my back yard.

A loaf of bread

Motherfuckin' bread...

(secretly half cheese)

That's why I'm so sketched out about Rust...

Man, as much fun as it is to shit on Micropython, the stuff it does behind the scenes to run on potatoes is friggin' amazing.

Hell yeah. Now with all this extra RAM, maybe I can put that entire episode in the firmware so they can watch it on a breadboard.

Oh nice, thanks! Maybe I'll just skirt the issue like I did with slow filesystem writes and have the logo change to a "GC busy" color if they get too long.

Haha omg brutal. I should probably do some actual performance testing.

If you or @rebelmike.bsky.social want to save me from doing something stupid in my Micropython config, here's the code:

github.com/Architeuthis...

I have no idea what I'm doing but it generally seems to work

running a psram test in micropython

mpconfigport.h with MICROPY_SPLIT_HEAP enabled

I was pleasantly surprised to find there's actually a flag in the port config called MICROPY_SPLIT_HEAP.

But I haven't looked at the back end code. I'm sure I will eventually when some nonsense comes up, so fix it before I have to gaze upon these horrors.

I'm taking preorders at a discount, but it'll be like a month before they ship because *of course* I design new stuff right before Chinese New Year.

Feel free to just wait until they're in, it's unlikely they'll sell out.

ALASKAN BULL WORM! Jumperless V5 PSRAM Mod Kit 8 megabytes of extra room for activities! Do PCB assembly crimes in the process! The Jumperless V5's RP2350B has 520kB of RAM, which is pretty awesome for a microcontroller. But in the course of scope...

Woo! The ALASKAN BULL WORM! PSRAM Mod Kits are ordered, and I wrote a whole thing about them in my store.

Ha yeah, I need to remind myself how ridiculously tiny this board is so I can stop nudging shit around and just send it.

Thanks. I cannot.
