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

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.

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 don't remember ordering this JDI MIP display (like an off-brand SHARP Memory LCD), but drunk Aliexpress Kevin really knocked it out of the park on this one.

Holy shit youguise, I think I cracked it. Serial passthrough in 5.3.1.0 is now totally asynchronous and doesn’t even really need the main CPU, it’s all handled in interrupt context (by overriding the irq handlers provided by SerialUSB and SerialUART).

I just made a silly little VSCode extension that colors your code based on how old it is.
Kinda handy if you're constantly Ship of Thessuesing a huge scatterbrained codebase like I am.
