๐ฉ๐ถ๐ฑ๐ฒ๐ผ ๐๐ฒ๐๐ฐ๐ฟ๐ถ๐ฝ๐๐ถ๐ผ๐ป This tutorial is about RS-485 communication using the MAX485 Module from Maxim Integrated. If you've worked with microcontrollers before, you might know that protocols like UART, I2C, and SPI are great for short distances. But when you start extending those wires, problems can crop upโlike lost or corrupted data. That's where RS-485 comes in, letting you communicate over distances as long as 1200 meters without a hitch.
In this video, weโre focusing on the MAX485 IC, a sturdy little device thatโs built to handle RS-485 communication even in places with a lot of electrical noise. Weโll explore how to set up your Arduino to communicate using simplex, half-duplex, and full-duplex modes. The MAX485 is perfect RS-485 Module as it operates on 5V, can handle data speeds up to 2.5 Mbps, and allows up to 32 devices on the same communication line.
Weโll walk you through everything from the basics to more complex setups, showing you how to manage sending and receiving data with ease. Whether youโre setting up a network of devices or just experimenting with new ways to communicate, this tutorial has got you covered.

My current experiments into building a studio/broadcast camera based on the Raspberry Pi 4 and the HQ camera module. Currently allows outputting 1080p30 video over HDMI (can be raised to 60fps if the h264 encoder is disabled) and outputs a user interface to the DSI output.
The source code is currently available at https://github.com/MartijnBraam/picam but I guess this repository will be renamed once I come up with a better name :D

๐ฐ๏ธ Rebuilding a Legend: Vintage Yaesu FT-2500M Digital Conversion "Vintage equipment is part of my religion." In todayโs episode, we are taking a piece of "ancient" ham radio equipmentโthe legendary Yaesu FT-2500Mโand giving it a full digital upgrade. Weโre proving that old ham radio equipment doesn't belong in a museum; it belongs on the airwaves! By combining this vintage radio with a Raspberry Pi Zero 2W and the Digirig Mobile, we are creating the ultimate portable digital ham radio powerhouse. ๐ ๏ธ The Build: Old Meets New We dive deep into the digirig setup and show you how to interface digirig cables with a 30-year-old two way radio. This isn't just a simple modification; it's a complete tech explained tutorial on turning a mobile rig into a modern TNC (Terminal Node Controller) using Linux and the AX.25 protocol. In this video, we cover: Digirig Mobile Setup: How to connect the Digirig to the Yaesuโs data port. DigiPi Setup: Installing the Digipi image on a Raspberry Pi for headless operation. Digipi Winlink: Sending emails over RF using a Winlink Express tutorial flow. Digipi APRS: Setting up an APRS radio node for location tracking and SMS messaging. Power Management: How a ham radio battery keeps this small-footprint Raspberry Pi project tutorial running in the field. ๐ก Why Digital Communication? Whether you are a prepper looking for emergency off-grid comms or a hobbyist exploring SSTV and digital communication, this setup is a game changer. We show you how to leverage Winlink ham radio and APRS ham radio to stay connected when the grid goes down. Equipment Featured: Radio: Yaesu FT-2500M Interface: Digirig Mobile & Custom Digirig APRS cables Computer: Raspberry Pi Zero 2W (The Pi that punches above its weight!) Software: DigiPi (APRS, Winlink, Direwolf)
