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…

Weather probes are key devices for collecting atmospheric data and improving weather forecasts. These probes, launched daily worldwide, ascend to high altitudes and gather crucial information like temperature, pressure, and humidity. The idea of automating predictions emerged during a probe hunt with EB1A. As we approached the site, there was a “sudden silence” — we discovered that the probe had already been picked up. That was when I decided to develop a system to make…

Satoffee⚡️ (Satoshi + coffee) is the name of this project that consists of a home coffee maker activated by payments made with Bitcoin using the Lightning Network. Can anything be cooler than this? In broad terms, what I have done is a small hack to the coffee maker to disable the only button it has, which is the coffee serving button. That button is then enabled with the help of a relay controlled by a…
