Supports I2C, SPI, PIO, UART over GPIO pins. USB interfaces. Programmable voltages. Has an FPGA on board for emulating other devices. SMA connectors for antennae. IR transmission and reception. Speaker and microphone.
They even ported the firmware to the Defcon 32 badge.
Shellminator is an easy-to-use terminal interface library designed for microcontroller environments. Thanks to its low resource usage, it can run on almost any microcontroller. It’s Arduino-compatible out of the box, making it accessible for both hobbyists and beginner programmers.
If your device is offline, you can now host the necessary web pages directly from the microcontroller. No external server needed! You can create progress bars, buttons, selection lists, plots, level meters, and even notifications. You can password-protect your terminal.
Highly, almost stupidly configurable. More like a shell than a serial terminal.
MeshCore is a lightweight, portable C++ library that enables multi-hop packet routing for embedded projects using LoRa and other packet radios. It is designed for developers who want to create resilient, decentralized communication networks that work without the internet.
MeshCore now supports a range of LoRa devices, allowing for easy flashing without the need to compile firmware manually. Users can flash a pre-built binary using tools like Adafruit ESPTool and interact with the network through a serial console. MeshCore provides the ability to create wireless mesh networks, similar to Meshtastic and Reticulum but with a focus on lightweight multi-hop packet routing for embedded projects. Unlike Meshtastic, which is tailored for casual LoRa communication, or Reticulum, which offers advanced networking, MeshCore balances simplicity with scalability, making it ideal for custom embedded solutions., where devices (nodes) can communicate over long distances by relaying messages through intermediate nodes. This is especially useful in off-grid, emergency, or tactical situations where traditional communication infrastructure is unavailable.
MeshCore is designed for use with:
- Heltec V3 LoRa Boards
- RAK4631
- XiaoS3 WIO (sx1262 combo)
- XiaoC3 (plus external sx126x module)
- LilyGo T3S3
- Heltec T114
- Station G2
Rayhunter is an IMSI Catcher Catcher for the Orbic mobile hotspot.
THIS CODE IS PROOF OF CONCEPT AND SHOULD NOT BE RELIED UPON IN HIGH RISK SITUATIONS
Code is built and tested for the Orbic RC400L mobile hotspot, it may work on other orbics and other linux/qualcom devices but this is the only one we have tested on.
Once installed, rayhunter will run automatically whenever your Orbic device is running. It serves a web UI that provides some basic controls, such as being able to start/stop recordings, download captures, and view heuristic analyses of captures.
A disaster-resilient communications network powered by the sun.
When the critical infrastructure that so many of us take for granted goes away, how do we organize ourselves and our communities to respond?
If recent ecological disasters have demonstrated anything, it is the inadequacy of existing models and tools to provide efficient allocation of resources, access to emergency communications, and effective coordination of human effort. Few if any solutions exist that are off-grid, affordable, reliable, easily deployed, and openly standardized.
JTAGulator alternative for RP2040 microcontroller based development boards including RPi Pico.
Connect the RP2040 microcontroller based development board running blueTag to your computer using USB cable. Connect the development board's GPIO pins (GPIO0-GPIO15 so 16 channels in all) to your target's testpoints on the PCB. Connect the development board's "GND" pin to target's "GND". Connect to your RP2040 using a terminal emulator. blueTag supports auto-baudrate detection so you should not have to perform any additional settings. Press any key in the terminal emulator program to start using blueTag. The firmware methodically pokes at all of the connected lines to figure out what kind of interface it is (JTAG, I2C, SPI, etc) and which line is hooked to which pin of that interface for you.
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.
flashrom is a utility for detecting, reading, writing, verifying and erasing flash chips. It is often used to flash BIOS/EFI/coreboot/firmware images in-system using a supported mainboard, but it also supports flashing of network cards (NICs), SATA controller cards, and other external devices which can program flash chips. Can also be used for dumping the contents of SPI chips for analysis.
It supports a wide range of flash chips (most commonly found in SOIC8, DIP8, SOIC16, WSON8, PLCC32, DIP32, TSOP32, and TSOP40 packages), which use various protocols such as LPC, FWH, parallel flash, or SPI.
Uses the GPIO3 pin of an ESP8266 to broadcast analog television signals. Broadcasts on broadcast channel 3 (60-66 MHz).
Sniffle is a sniffer for Bluetooth 5 and 4.x (LE) using TI CC1352/CC26x2 hardware. Sniffle has a number of useful features, including: Support for BT5/4.2 extended length advertisement and data packets, Channel Selection Algorithms #1 and #2, all BT5 PHY modes, sniffing only advertisements and ignoring connections, channel map, connection parameter, and PHY change operations, and capturing advertisements from a target MAC on all three primary advertising channels using a single sniffer. This makes connection detection nearly 3x more reliable than most other sniffers that only sniff one advertising channel. Can write traffic to PCAP files for external analysis.
Requires a supported Bluetooth interface, such as the TI CC26x2R, CC2652RB, CC1352R, CC1352P, or the EC Catsniffer V3 CC1352. The documentation has a complete list of Bluetooth sniffers and links to get them.

Valetudo is an opinionated software solution for cloud-free vacuum robots installed on thousands of robots. Since it was started in 2018, it has matured to a reliable fire-and-forget solution that just works. The obvious upside of this is that all your data stays on your robot. It also means that you won’t need to have a working internet connection just to control your local vacuum robot anymore. Commands usually execute much faster and more reliable, as they don’t have to detour through some server in a datacenter far away from you, which might be overloaded or even on fire.
Furthermore, the robot will continue working even after the vendor has ended support for that model and shut down the corresponding servers. This is a huge issue with IoT devices. They brick all the time because the vendor gets sold, changes its business model, runs out of venture capital, is bankrupt, gets hacked, and more.
Multiple integrations with other self-hosted software for convenience.
The Hacktic Demon Dialer is a compact inband signalling device, aka a blue box. With many additional features. The DemonDialer was designed by Hacktic in 1991, see hacktic 14-15.
