Over 6 weeks I built and verified a complete chip architecture on a $60 Android phone using Termux, iverilog, and Yosys.

Phoenix 4096×4096 specs: - 16,777,216 MAC units (analog in-memory compute) - 50,331 TOPS @ 3GHz (25× NVIDIA H100) - 512 deterministic reasoning cores - 2 TB/s memory bandwidth - All verified in simulation

Hardware verified (15/15 passing): - Half Adder → Full Adder → 8/16/64/128/256-bit ALUs - 8-bit CPU (Fibonacci working) - RISC-V core - FPU (IEEE 754) - GPU SIMD - Complete Phoenix SoC

Also built: - ULA compiler: Plain English → 12 languages (Python, Rust, Java, Assembly, COBOL, Fortran, C, C++, Go, Kotlin, Solidity, TypeScript) - RF presence detection: 2-person tracking via WiFi signals, no cameras, 91% gesture accuracy

Built in Sikeston, MO on a $60 Android. No laptop. No cloud. No funding.

Looking for: Chip designers, semiconductor engineers, anyone interested in open silicon or analog computing. Want to tape out with Efabless or similar.
