Meshtastic® is a project that enables you to use inexpensive LoRa radios as a long range off-grid communication platform in areas without existing or reliable communications infrastructure. This project is 100% community driven and open source!
Long range (331km record by MartinR7 & alleg). No phone required for mesh communication. Decentralized communication - no dedicated router required. Encrypted. Excellent battery life. Send and receive text messages between members of the mesh. Optional GPS based location features.
Meshtastic utilizes LoRa, a long-range radio protocol, which is widely accessible in most regions without the need for additional licenses or certifications, unlike HAM radio operations. These radios are designed to rebroadcast messages they receive, forming a mesh network. This setup ensures that every group member, including those at the furthest distance, can receive messages. Additionally, Meshtastic radios can be paired with a single phone, allowing friends and family to send messages directly to your specific radio. It's important to note that each device is capable of supporting a connection from only one user at a time.
At its core, CATS is a packet radio standard primarily designed for autonomous position reports, but is versatile enough to support a much wider scope of communication. CATS packets are extremely versatile, consisting of multiple "Whiskers" which make up the packet. Whiskers come in several types. For example, a typical CATS position beacon would likely contain an Identification Whisker, GPS Whisker, and potentially a Comment Whisker and Timestamp Whisker. Different Whiskers can be mixed and matched to allow a wide range of data to be encoded. Detailed information on CATS can be found in the standard, linked below.
CATS is ultimately meant to be a replacement to APRS. Although APRS was magnificent when it was first developed, current technology allows us to do better. APRS also suffers from decades of bloat, making the standard difficult to learn.
This WeeWX extension allows the generation of APRS-compliant packets containing weather information collected by weewx. This extension was written for the purpose of easy integration with aprx. When this extension is enabled, weewx will generate a new APRS packet every StdArchive.archive_interval seconds.
This guide is meant for advanced users who wants to get rid off Windows 11's bloatware and telemetry. Last tested on Windows 11 22000.376. Gets rid of bloatware. Disables most of the telemetry. Better performance. Optimizes Windows 11 for gaming as well as productivity. Strips Windows 11 to barebones (In Advanced removal below). Unfortunately, it also breaks Sysprep and the sfc/scannow commands.
This is a GPS/radio tracker for high altitude balloons. It uses a GPS receiver to determine its position, and a LoRa transceiver to transmit that position to the ground. It is written in C for the Pi Pico microcontroller, using the official C/C++ SDK. The resulting executable code can be downloaded to the Pico using a serial programming/debug cable as described in the Pico C/C++ SDK manual. You will need a means of receiving the telemetry from your tracker. One popular option is the Pi LoRa HAB gateway.
This post will detail the steps involved to configure an Android device to audit the traffic of any app installed on it, requiring no other device to be physically present. The device will have to be rooted in order to install the software required for this setup. All of the software required in this post is free of cost and open-source, not requiring an extra penny of investment above and beyond that of the device itself. The end result will allow the user to open an app in a specialized way that allows the traffic to be logged, without attaching extraneous devices or requiring the device to be connected to any specific network or access point.
A web application (personal and otherwise) for tracking high altitude balloons, radiosonde beacons, and so forth on a world map. Desktop and mobile friendly.
