A port of the PCem PC emulator to the browser. The native wxWidgets/Qt front end is replaced by a headless Emscripten build of the emulation core and a single-page web app that recreates PCem's "Systems" workflow.

Transmit and receive mechanical-television-style video through audio over a cable, WAV file, or pure software loopback. Classic 32-line club NBTV, and experimental wideband modes up to 480 lines that turn a 24-bit/192 kHz sound card into a surprisingly capable video link. It can even send *files* over the video channel as a stream of QR frames.

A comprehensive, multi-phase Python simulation suite and Graphical User Interface (GUI) for a highly parameterized Switched-Reluctance Pulse Motor (often referred to as a Bedini topology). The software calculates all electromechanical properties in real-time and render a live visual simulation of the rotor dynamics and circuit transients.

This project demonstrates browser-based x86 emulation and snapshot-based system restoration for research, educational, archival, and experimental purposes.

Advanced Image-Based Audio Editor & Synthesizer With Creative Spectral Manipulation.

A physics simulation of Howard Johnson's **"magnetic gate"** motor (U.S. Patent 4,151,431): a magnet **cart** travels a circular track by a configurable array of stator magnets with small **rubber flux-gate magnets** placed at the null zones Johnson's actual regauging mechanism. Computed from a Coulombian force model, with a full live GUI

Highspeed Soundcard IP Modem that turns two PCs' soundcards into a point-to-point network link. It modulates IP packets onto audio with OFDM (DMT), bonds the left and right stereo channels into two parallel lanes, protects everything with Reed-Solomon FEC and an ARQ with fast retransmit.

A fully in-browser voice assistant with a retro CRT robot face. Everything runs locally in the browser: LFM2 brain via wllama (multithreaded WASM llama.cpp), Whisper ears via transformers.js (in a Web Worker), and the browser's built-in speech for her voice.

A cleaner desktop app for softening harsh high-frequency audio, peak-normalizing, and exporting polished WAV files. Audio De-Emphasis Studio is a modernized version of the original Tkinter audio processor I worked on. It keeps the same core idea.

Experimental SSTV Studio Time-compressed slow scan television: encode an image to SSTV audio, squeeze the audio to a fraction of its length before it hits the air, and let the receiving station stretch it back and decode as usual. Half (or a quarter) of the airtime, paid for with a few seconds of number crunching on each end.

The composite back end of OmegaFM as a single file, for stations that already have processing they love and just need a broadcast-grade MPX + RDS box

OmegaFM is a complete digital FM broadcast audio processor: an Optimod-style multiband chain, distortion-cancelled clipping, a full stereo generator with RDS, and BS.412 compliance — in one app written in python that runs on the hardware you already own.

PhaseScope turns a stereo sound card into a sensitive differential phase instrument with a real-time anomaly detector, NTP-disciplined event times tamps, and built-in immunity to buffer glitches and clock drift.

Press a WAV file onto a PNG that *looks* like a vinyl record and *is* the audio. The fine groove texture in the image is the actual sample data: every audio sample owns exactly one pixel along an Archimedean spiral, with its brightness encoding the μ-law amplitude. Send someone the PNG and they can play it or scratch it on the virtual turntable.
