Digital Logic Editor

A real-time, gate-level digital logic editor and simulator written in Rust, for web (wasm) and native. Includes an RV32IMA computer that boots Linux, a simulated Arduino Uno (ATmega328P) flashable from Arduino IDE/PlatformIO, Verilog import, multiplayer lockstep editing, WASM user components, and an MCP server for AI control.

Tactile Digital Logic Exhibits (MS thesis)

A framework for rapidly prototyping tactile digital-logic exhibits on a distributed architecture. Simulated I/O hardware (buttons, LEDs, etc.) can be swapped for real hardware one part at a time via an abstracted implementation and a distributed communication protocol. Demonstrated with a CPU exhibit.
