The Bus Pirate is an amazing open-source tool for hardware debugging. It supports a wide range of protocols like SPI, I2C, UART, and JTAG, making it ideal for exploring routers, IoT devices, or any hardware utilizing these common protocols. Once a device is disassembled, several directions open up for hardware exploration. In this post, we’ll […]
Receiving NOAA APT Satellite Transmissions with a Software-Defined Radio and Simple Antenna
This guide explores the reception of Automatic Picture Transmissions (APT) from NOAA satellites using a Software-Defined Radio (SDR) and a suitable antenna. While NOAA operates numerous satellites, our focus will be on NOAA-15, NOAA-18, and NOAA-19, which are equipped to broadcast imagery back to Earth. For optimal reception of the 137.5 MHz frequency band utilized […]

Taming the Beast: A Modern Starter Solution
Between 1986 and 1993, Lamborghini manufactured the LM002, an off-road vehicle with a surprising origin story. The initial prototypes weren’t intended for dusty trails and suburban driveways; they were designed for military use, aiming to compete with and even replace the Hummer. Unfortunately for Lamborghini, the military contract never materialized. The LM002 prototypes proved too […]

Part 2: Build your own UAV Predator drone.
This is a continuation of the Build your own UAV Predator drone. In this section I cover the configuration of the UAV and the testing. The main connection between the Raspberry Pi and the flight controller will be done through the telemetry port. The flight controller has two telemetry ports and in this case we […]
Part 1: Build your own UAV Predator drone.
Building Your Own UAV: The $250 Drone Think a military-grade drone is out of reach? Think again! Setting out to answer a simple question: Can you build an open-source UAV drone for a fraction of the cost of something like a Predator? The answer, with some limitations on distance and payload, is a resounding yes. […]
