Man, PIO is so ridiculously OP.

The ALASKAN BULL WORM! PSRAM Mod kits are in. I was worried about the fit around that flash chip but the vibes-based clearance was so on point you could probably get away with just friction fitting them.

**Refuses to elaborate further (but mostly because I have no idea wtf this thing will actually do yet)**

ALASKAN BULL WORM update: They look sick af.

I love how fabs have such low self-esteem. They'll be like, "hey those silkscreen features are too tiny, our terrible process will turn them into mush" and you say "that's fine, just try your best" and then they fucking nail it every time.

I finally found a use for 32 layer PCBs

I'm sorry I'm 20 minutes late to show you this very important information: www.youtube.com/watch?v=_qO6...

reading jumperless docs, one of the most insane things i have ever seen

wtf, I still have 0.005 mm clearance!!1!

This is @joeycastillo.bsky.social's fault

Which footprint should I use here? Yes.

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

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

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

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.

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.

@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)

Motherfuckin' bread... (secretly half cheese)

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

I regret to inform everyone that this bit will continue.

I'm considering making an ALASKAN BULL WORM! mod kit for the Jumperless to give it 8MB of PSRAM for Micropython and a better onboard logic analyzer. Like anything I've released as a kit, it will involve committing some heinous PCB assembly crimes.

Jumperless V5 now has a built-in 1960s wallpaper generator! (It's actually showing the physical paths your connections take through the 12 crossbar switches in the same colors they appear on the breadboard)

These beautiful mfs seriously make the greatest hardware “review” show ever; because they’re not actually reviewing anything, it’s just slice-of-life first few hours with a new dev board and omg I’m terrified.

tag yourself

I don't think I've had a reason to solder the probe sense pads on without the breadboard underneath and it looks super weird. (Someone wanted to do dome hardware mods to their Jumperless that'll be a lot easier if I send them one partially assembled)

omg I'm reading this dumb twitter article but can't continue because I'm laughing too hard at this diagram. Like, using this as a definition of an intelligent system then crashing into the fucking rocks because you don't know wtf a lighthouse is.

When you scope creep a project so hard you need to draw your board outlines in Fusion 360...

Woo! Just got a box of 200 more Jumperless V5s. These are rev 7, the only real difference is they have 2 friction-fit OLED headers on the main board, so it can sit in that crevice between the Nano headers (or scoot it over to the right if you have something in there that would cover it.)

Wowowow! Husband got me a jumperless for the holidays :o I'm so stoked! What a beautiful piece of hardware that @architeuthisflux.bsky.social has created Excited to shirk my other projects and play with this lol

I was showing my mom the ways of using Adobe's own products against them to get a student discount and this happened

Please let me name your baby

It's the time of year where I get to show off all the cool things our friends make! Check out the 2025 Alpenglow Gift Guide and find something fun for that electronics nerd in your life (and maybe that's you!) www.alpenglowindustries.com/pages/2025-g...

what

First one to guess what the hell is going on in this video gets a high five.

This is the sort of nonsense you end up doing when trying to support existing hardware rather than just selling a new revision.

Move aside @adobe.com, there's a new drawing app in town...

Seeing all those LLM CLI tools having those fun block character title screens made me want my own. And no, I didn't have an LLM make this, just 6 hours toggling pixels in Photoshop. Pixel art is such a hyperfocus black hole.

Oh no! Ants got into my lab and are all over my breadboard. Luckily, it's the species commonly found in circuit simulators to visualize current flow. They finally broke out of the simulation onto real hardware. Good for them.

Whatever you think this is for, I promise you it's more ridiculous than that.

My hobby: putting cap sense pads in everything and then never actually using them

I need to reorder another batch of Jumperless V5s so of course I had to change something. rev7 will have 2 sets of wiggly friction-fit OLED headers on the main board. And you can scoot it over to the right when it would be covered with an Arduino or the Raspberry Pi adapter or something.

omg finally, the feature everyone wanted on the OG Jumperless like 2 years ago. Wire colors on the breadboard now match the ones you set in your @wokwi.com project!

Quick demo of the most basic (but still magical) feature of Jumperless V5 by @architeuthisflux.bsky.social: making connections without jumper wires. It can do so much more: power supply, multimeter, oscilloscope, function generator, logic analyzer, etc. Pardon the shaky, over-caffeinated hands. 😆

I know I'm late to the @architeuthisflux.bsky.social Jumperless V5 party, but this thing really is brilliant in every way! 🤩 Get yours: www.crowdsupply.com/architeuthis...

Kinda crazy how easy it is to bust out one-off PCBs with a sharpie and some liquids

This object continues to get sillier...

men will literally do whatever this is instead of using a slip ring

Some echinoderms can evert their stomachs to digest prey outside of their body. Here we see a starfish eating a selector switch:
