Projects

Portquiz tests outbound TCP and UDP connectivity to remote hosts by attempting connections across specified port ranges. The tool identifies which ports can successfully establish connections through network infrastructure such as firewalls, NAT devices, and proxies. The program can detect deep packet inspection (DPI) filtering and other network-level blocking mechanisms. It supports testing individual ports or scanning complete port ranges, with cross-platform compatibility across Windows, macOS, and Linux systems.

Caddy Dynamic RemoteIP is a Caddy web server module that provides dynamic IP address matching capabilities. The module implements the http.matchers.dynamic_remote_ip matcher, which allows matching requests based on remote IP addresses that are dynamically sourced from configurable modules. Unlike static IP matching, this module enables real-time IP range updates through pluggable IPRangeSource implementations. This is useful for scenarios requiring dynamic access control based on changing IP ranges, such as cloud provider IP lists or threat intelligence feeds.

TOOR.sh is a cloud and VM hosting service operated by ToorCon, a 501c3 non-profit organization that provides free hosting resources for security research and public benefit projects. The service includes dedicated servers for VMs, storage, and databases, along with their own ISP infrastructure (AS22296). The platform offers various free tools including IP address lookup services, network speed tests, and internet infrastructure services such as RIPE Atlas probes, BGP feeds, Tor nodes, and Signal TLS proxies. TOOR.sh operates on a volunteer basis with a “best effort SLA” and accepts donations of hardware, network resources, or funds to support their mission.

WebSerial Bruteforce automatically determines the correct baud rate for UART serial devices by testing common communication speeds and analyzing the returned data. The web application uses the WebSerial API to connect directly to serial devices from the browser without requiring additional software. The tool iterates through standard baud rates and measures the amount of ASCII data returned at each setting, selecting the configuration that produces the most readable output. This is useful for reverse engineering or troubleshooting unknown serial devices where the communication parameters are not documented.

USB Meter is a web application that connects to Atorch power meters via WebBluetooth to log and display electrical measurements. The application reads real-time data including voltage, current, power, energy, capacity, resistance, and temperature from compatible Atorch USB power meters. The web interface provides data logging capabilities with the ability to reset, pause, and save measurement sessions. Using WebBluetooth API, the application eliminates the need for additional software installations, operating directly in compatible web browsers with Bluetooth support.

An opkg repository that builds Tailscale combined packages for OpenWrt devices, specifically providing a backport of Tailscale for OpenWrt 19.07. The project addresses the lack of official Tailscale packages for older OpenWrt versions by providing a flexible build system that generates installable packages across multiple hardware architectures. The repository includes automated build scripts that create opkg feed and package files, allowing users to easily install and configure Tailscale on their OpenWrt 19.07 devices. This enables secure mesh networking capabilities on legacy router firmware, making it simple to connect older OpenWrt devices to a Tailscale network for remote access and site-to-site connectivity.

Mag Encode is a web-based magnetic stripe card encoder that generates audio signals for encoding data onto magnetic stripe cards. The application runs entirely in the browser, processing encoding operations client-side without transmitting data to external servers. The tool supports configurable encoding parameters including frequency settings, reverse swipe options, and various advanced configuration options for different magnetic stripe formats. It converts digital data into the appropriate audio waveforms that can be played through audio output devices to magnetically encode stripe cards.

Broken DNS performs lame delegation checking at scale to identify DNS nameserver configuration issues. The tool validates DNS delegation by checking if nameservers properly respond to queries for zones they are supposed to be authoritative for. The Go implementation can process large numbers of domains and nameservers to detect misconfigurations where nameservers are listed in delegation records but do not actually serve the zone data. This helps identify broken DNS setups that can cause resolution failures.

Minimalin Reborn is a minimalistic watchface for Pebble smartwatches, featuring a clean design with customizable colors and optional information displays. The watchface uses a custom font called Nupe and provides configurable elements including weather data and step tracking integration. This project is a fork and modernization of the original minimalin watchface, updated to work with current Pebble development tools and the Rebble ecosystem. The watchface supports both color and monochrome Pebble devices with adaptive styling and user-configurable display options.

Homeplate is an ESP32-based e-ink dashboard that displays data from Trmnl and Home Assistant on an Inkplate 10 device. The firmware fetches and renders various dashboard widgets including sensor readings, WiFi QR codes, and system status information. The implementation uses FreeRTOS on ESP32 to manage display updates, network connectivity, and power management for the e-ink display. It supports multiple data sources and configurable display layouts for home automation monitoring.
