Apoya a Harald

Hi, I'm Harald! 🛠️

My passion for electronics and technology started early, heavily inspired by my father, who was an electrician. Today, I love sharing that passion through my technical blog, focusing on embedded systems (like the ESP32 family), LoRa networks, vintage clock restorations, and 3D printing.

Writing comprehensive, deep-dive tutorials, designing PCBs, and sharing clean code takes a significant amount of time, coffee, and hardware testing.

Every contribution goes directly back into the blog. It helps me fund new development boards, sensors, and filaments for upcoming projects, and keeps the website completely independent and ad-free.

If my articles or code saved you hours of debugging or helped you finish your own maker project, considering buying me a coffee. I truly appreciate your support! Happy hacking!
