MASN V2.0 is an evolution of the original MASN PCB, developed to improve the reliability of the Meshtastic solar node in real-world, long-term outdoor installations. The first version of the project was focused on simplifying the assembly of an autonomous solar node by reducing wiring, integrating the main modules into a single PCB, and using components that are easy to solder. That version remains valid and continues to be the recommended option for users looking…
Anyone approaching Meshtastic usually finds the same thing: tutorials full of tangled wires, tiny solder joints, and boards designed for people with solid electronics experience. That’s discouraging for anyone just getting started — and even more frustrating if your goal is to build a stable solar-powered node for the roof or the field. In A Coruña, a group of enthusiasts and makers began meeting at Bricolabs to build nodes using affordable designs like fakeTek and…
The FaceTime HD camera of MacBooks is proprietary hardware that requires a specific process to work on TailsOS. Below, I’ll show you how to enable it safely using a simple script and checking your kernel version beforehand to ensure compatibility. The problem: why doesn’t the camera work on TailsOS? The FaceTime HD (Broadcom 1570) camera is a proprietary hardware component that requires specific drivers to function properly. Since TailsOS is a privacy-focused operating system based on Debian, it does not include support…
In radiofrequency, precisely adjusting an oscillator without tools like oscilloscopes or frequency counters can be a challenge. However, together with EB1A, we discovered that it’s possible to achieve an accurate calibration of the SI5351 module using a simple JavaScript calculation tool, ideal for DIY projects like WSPR. Project goal We want the oscillator to be as close as possible to the desired frequency (in this case, 14 MHz). We’ll use a calibrated receiver, such as…
