A radio repeater controller (supporting both simplex and duplex operation modes) for the RaspberryPi.

Set your radio to 148.500 MHz, select FM, USB, or CW mode, and set the squelch to 0 or 1. Then, extend your radio's antenna toward the monitor's HDMI port, and congratulations—you can now transmit in Morse code directly from your monitor!

A stealth-focused kernel-mode virtual HID mouse driver for Windows. Built with KMDF and VHF for precise, hardware-level input simulation using covert shared-memory IPC.
