Alien Motion Tracker Secondary PCB
Smith Sep 04,2025
Over three videos I created a full qorking M314 Motion Tracker from the Aliens film. This tracker actually tracks movement and motion using the DreamRF Radio Hat for the Raspberry Pi.This PCB is the SECOND of TWO required to build this project. This board is designed to allow easy connection of all of the other parts used by this project with easy connection to the raspberry pi PCB 1 via a simple FPC/FFC cable.On this board you will find:FPC: A bottom-contact connector for a 0.5mm pitch ~100mm R...

Build a Raspberry Pi Pico SDR Radio with Waterfall Display
Pavleski Sep 04,2025
 Software-defined radio (SDR) is a radio communication system where components that have traditionally been implemented in analog hardware (such as mixers, filters, amplifiers, modulators, and demodulators) are instead implemented by means of software on a computer or embedded system. The biggest advantage of SDR is its flexibility. Because the functions are handled by software, you can change the radio's behavior by simply updating the software.  This time I will present you...

Raspberry Pi - all GPIO 5V adapter
Loranger Aug 05,2025
Have you ever wanted to interface your Raspberry Pi to something that only uses +5V logic levels? As you quickly came to learn, the GPIO on the Pi are not 5V tolerant, so hooking up the device to your Pi would render the board(s) damaged.  This little interface board takes care of the issue by providing level shifting circuitry for ALL of the GPIO pins to a 5V level, while still allowing you access to the 3.3V logic level signals as well.With this board, you can work with 3.3V GPIO and...
