Part 2 of my YT Hardware Hacking Series

Hey folks, as promised, Part 2 of my video series on hardware hacking access control systems is now live! This time, we’re building the actual open-source door controller – first on a breadboard, then as a soldered prototype on perfboard. We also explore the GitHub project behind the system – looking at supported reader types, basic architecture, and what to watch out for if you want to build it yourself. 🔧 In this episode, I cover: • How to properly set up a step-down converter • What to know about relay modules • Troubleshooting when your soldered build doesn’t work as expected 😅 • And how to use the Flipper Zero as a basic cable tester 💡 Why bother? Because in future episodes, we’ll flip the script and hack our own access control setup! We’ll explore whether a split design (reader + controller) actually increases security—or just shifts the weak spots. We’ll also analyze the PCB, communication lines, and look for exploitable vulnerabilities. 📺 Watch Part 2 now: 🔓 Hardware-Hacking Part 2: Open Source Türsteuerung bauen – vom Steckbrett zur Platine 🚀 (#039) https://youtu.be/6hrlLVSxcps The video is in German, but – just like Part 1 – it includes English subtitles. ⚠️ Firmware flashing and user setup will be covered in Part 3. This episode is all about hardware prep for what’s coming next. For all who missed it - here is Part 1: 🔓 Hardware-Hacking Part 1: NFC-Schließanlage hacken - mein Mega-Projekt! 🚀 (#038) https://youtu.be/Y_j83VBhsoY submitted by /u/Einstein2150 [link] [comments]
