Jumperless V5 by @ArchiteuthisFlux is the most glorious example of feature creep I have ever experienced.

I finally got a chance to see Jumperless in action at @crowdsupply #Teardown2025 and it is everything you didn’t know was possible in a breadboard, but somehow can’t live without.

Solderless breadboards are useful.
Electrically configurable breadboards are cool.
Programmable breadboards with an interactive probe are amazing.
Programmable breadboards that double as a display are awesome.
Being able to play Doom on said breadboard is mind blowing.

If you haven’t backed this unbelievable project yet, it is not too late. You can still place pre-orders:

Unboxed my Jumperless from @ArchiteuthisFlux recently. It's absolutely beautiful and packaged so well. You can read about my unboxing experience on Patreon: https://www.patreon.com/posts/132126594. (The article is open-access)

I continue to cook with this frame dumping stuff.
Now you can pipe the state of every LED on the board in real time to separate USB endpoint, and then the OLED to yet another, so you can basically have two external monitors for your Jumperless.
Language barriers can be so fucking terrifying, this is my injection molded cable supplier.
It's like the manufacturing equivalent of "we need to talk" and then they ask if you want to go get lunch somewhere.

Oh also it uses a bunch of xTerm hacks to print the OLED's frame buffer next to the menu.

And it's downscaled from 128x32 by using combinations of the quarter block characters ▖ ▗ ▘ ▙ ▚ ▛ ▜ ▝ ▞ ▟ ▌▄ █ to show 4 pixels in a single character.

But don't worry! If you're a serious adult person who doesn't want to relive the whimsy of getting invited to a party in the 2000's, I've got you covered.
I just added font support for the V5's OLED and I'll give you one guess what the default font is.
Jumperless V5 by @ArchiteuthisFlux , arrival in Seattle! Congrats Kevin! Looking forward to this!
And here's what all 12 of those analog crossbar switches are up to. These are the same connections you see in the video, so if you stare at it long enough, it might eventually make sense.
