Former Achimota School graduate, Tyrone Iras Marhguy, has achieved a remarkable engineering milestone by building a computer brain from scratch at the University of Pennsylvania in the United States.
Marhguy first rose to prominence in 2023 after a legal battle with Achimota School over religious freedom in education.
Now, three years after graduating, he has turned his focus to technology and innovation as his educational journey continues in the States.
With no prior chip design experience, Marhguy dedicated more than 250 hours in his dormitory to designing and verifying a fully functional 8‑bit Arithmetic Logic Unit (ALU).
The project required painstaking assembly of 3,488 MOSFET transistors, one at a time, to create a processor capable of performing 19 distinct operations.
Reports indicate that his design was rigorously tested with over 1.2 million vectors, demonstrating both precision and resilience.
According to details of the project, Marhguy’s aim was to explore the fundamentals of computing and uncover what truly drives the CPU — often referred to as the “black box” of modern technology.
Phase one of the project is now complete, with the next steps including optimization, PCB assembly, soldering, and debugging.
Marhguy’s journey from Achimota School to the University of Pennsylvania continues to inspire many in Ghana and beyond, showing how determination and curiosity can push the boundaries of possibility.
