Tyrone Marhguy, a former Achimota School alumnus and a student of the University of Pennsylvania 🇺🇸, has built a computer brain from scratch in his dormitory, crafting a working 8-bit ALU with 3,488 transistors.
He is widely known for his deep-rooted court case he won against the Government of Ghana in 2023.
Built a computer brain from scratch in his dorm, one transistor at a time, Tyrone Marhguy spent 250+ hours designing and verifying a working 8-bit ALU made of 3,488 MOSFETs, capable of 19 operations and tested with over 1.2 million vectors. With no prior chip design experience, he dove deep into every gate and electron to understand what truly powers the “black box” we call a CPU.
Tyrone Marhguy (full name Tyrone Iras Marhguy) is a Ghanaian student and young academic achiever, known both for his educational accomplishments and his stand for religious freedom in education.
Phase 1 is complete, and next comes optimization, PCB assembly, soldering, and debugging
