We’re used to handheld Linux devices of varying usefulness appearing on a regular basis, but there’s something about the one in a video from [Rootkit Labs] which sets it aside from the herd. It’s a fork of a conference badge.
The WHY2025 badge had pretty capable hardware, with an ESP32-P4, a really nice screen, and the lovely SolderParty keyboard. Here it’s been forked, to become a carrier board for their previous project, the Flipper Blackhat. This is a Linux add-on for the Flipepr Zero, and it seems that plenty of people wanted it in a more useful context. The result is something that looks a lot like a WHY badge, but running Linux.
It’s a great shame when badges end up lying unused after the event, and ones like the WHY 2025 badge are a serious effort to make something that endures. Here, the badge endures in spirit by being forked and re-engineered, and we like it a lot. The full video is below the break.

“Flipepr Zero”?
I think it’s appropriate, hopefully it will create havok for scraping bots and below the radar of “script kiddies”. It’s a feature not a bug.
Might as well get used to it, cz spelling is a lost art these days.
I also talked at FOSDEM -> https://ftp.belnet.be/mirror/FOSDEM/video/2026/h1309/WDCDC3-the_blackpants_are_pants_for_your_blackhat.av1.webm
That keebdeck keyboard is something I’ve looked for for literally years. I got so excited, at last it exists a modular non Bluetooth keyboard! Sold out. Of course.
Anyway. Nice project looks great. It’s what I always wanted my graphing calculators to be. Mini Linux computers.
