A dynamic whole-home low latency audio router including embedded receivers and transmitters, support for many devices, and a custom audio processing engine.

ESP32/STM32 Projects

Projects such as a menu system for an eink touchscreen, video game controller adapters, and a tool to emulate the ballast on an Eiki projector allowing it to run with a replacement LED bulb.

Smaller Projects/tools

Smaller PC-based projects such as a real-time subtitle feed using Whisper, a tool to receive and process commands from LIRC and Magic4PC, and an onscreen joystick prototype.

Windows RT Jailbreak

Wrote the first user-accessible tool for jailbreaking Windows RT tablets. This was featured on XDA Developers, CNet and Engadget, among other websites.

3D Printing

Wrote a Klipper configuration to implement color mixing using CMYK with a commercially available 4->1 mixing hotend. I have also designed many random small things using Fusion 360.

I am always trying new configurations on my homelab and I have years of professional experience with systems administration.
