Score: 7.5/10 (Innovation: 7, Technical: 9, Documentation: 8, Utility: 6)

This project implements a software 10BASE-T Ethernet PHY and a wireless router entirely in Rust on a Raspberry Pi Pico 2 W, using bit-banged PIO and DMA for both TX and RX. It is interesting because it pushes the boundaries of what is possible on a low-cost microcontroller, combining custom hardware-level Ethernet decoding with a full TCP/IP stack and Wi-Fi routing.

Target audience: embedded developers, network engineers, makers
