Take it apartthen write it down.
Video and long-form walkthroughs for people who learn by building: a lab that actually works, badge hardware with the pads still exposed, and a first capture the flag that ends in a solved challenge instead of a closed tab.

Badge hardware hacking: find the debug header the vendor left behind
Conference badges are teaching boards with a silkscreen roadmap. Here is how to read one, find UART, and get a console on a device you have never seen.

CTF 01
Hack your first hack: an intro to capture the flag
Pick a platform, solve one beginner web challenge end to end, and build the note-taking habit that separates people who improve from people who plateau.
Who is doing the soldering
Nullbyte Labs is K0DA — a cybersecurity engineer who builds adversarial simulations for a living and conference badges for fun. The tutorials here are the notes taken while figuring something out, cleaned up so the next person spends their time on the interesting part instead of the setup.
Everything is aimed at people who are early but serious: you can follow a terminal, you own a soldering iron or want to, and you would rather understand the attack than copy the command. New tutorials land as a video and a write-up together.
