Now a student at the University of Pennsylvania in the United States, the young Ghanaian turns curiosity into craft, patience into precision, and persistence into progress.
Working quietly from his dormitory, according to the social media page Voice of KNUST, Tyrone has spent more than 250 hours building a functioning computer brain from scratch.
One transistor at a time, he designed, verified, and tested an 8-bit arithmetic logic unit comprising 3,488 MOSFETs, which performs 19 operations and was validated with over 1.2 million test vectors.
What makes the feat striking is that Tyrone had no prior chip design background; instead, immersing himself in fundamentals, studying every gate, pathway, and electron to understand what truly powers the black box known as a CPU.
According to the post, Phase 1 is complete, and next comes optimisation, PCB assembly, soldering, and debugging.

Rastafarian student wins case against Achimota School
Beyond engineering, Tyrone Marhguy remains a symbol of conviction and is widely remembered in Ghana for standing firm as a Rastafarian at Achimota School who refused to cut his hair.
That chapter culminated in a landmark court victory in 2023, affirming religious freedom in education, which was said to have sharpened his resolve and continues to inform his academic path.
Today, his new feat bridges theory and practice, showing how determination can translate into tangible innovation. Peers and observers have praised the project as a masterclass in learning-by-doing, where curiosity leads, and credentials follow.
As Tyrone advances to the next stages of the build, his story continues to inspire students at home and abroad. From Achimota to Pennsylvania, his journey is less about destinations than discipline, and more about building understanding piece by piece.
Looking ahead, the young innovator said that he planned to refine performance, reduce complexity, and document lessons for others eager to learn from his computer brain.
For many, it stands as proof that bold ideas paired with discipline can scale. In classrooms, dorms, and online forums, Tyrone’s progress continues to spark thoughtful conversation about access, mentorship, and perseverance.
