In this video, I'm analyzing a really confusing dialog on macOS. Let's dig a bit deeper into what it should do and what it's actually doing. #reverseengineering

@oflynn.com Does PhyWhisperer-USB have any official sellers besides Crowdsupply and Mouser?

Wait, it could be a USB-C, but on the other side.. SMA?

It‘s not a Pico and it has an RJ45 port, that‘s weird! 😂

The world champion at the time achieved ~10 keys/sec i.e. ~120WPM, still impressive today!

attempting to vibe-code my first piece of software that interfaces with an llm.. makes sense I guess?

I see! Never had issues citing your original domain, but also makes sense I guess. :)
Personally, I prefer cyberpunk.. 😉

Last weekend, Telekom changed their network name from "Telekom.de" to "Im besten Netz." 📶

Curious about how they did this? Will more ad campaigns follow? And what can you do to change it back?

Throwing the I/Q samples recorded using GQRX into #URH (Universal Radio Hacker) yields something interesting. Instead of the frequently used, basic on-off keying, we have some phase shifting going on here.

Let's check the center frequency first; I like to use #GQRX for that. It's only very slightly off at 26.994MHz.

The back says it's a 26.995MHz device, made in the Czech Republic. Model type GTF-27, which sadly gives no results on AliExpress.
