Tyrone Iras Marhguy is not your everyday student. From his dorm room, the young academic achiever has pulled off something many would consider impossible without a fully equipped laboratory; he built a working 8-bit Arithmetic Logic Unit (ALU) using only discrete MOSFETs.
What makes his achievement even more remarkable is that he had no prior experience in chip design when he started.
Driven by curiosity and determination, Tyrone dedicated over 250 hours to the project — carefully designing, simulating and verifying every part of the ALU from scratch.
In total, he used 3,488 MOSFETs to create a unit capable of performing 19 different operations, the kind of core computing functions that form the heartbeat of a CPU.
But he didn’t stop at building it; he tested it thoroughly, according to a post he made on Facebook.
Marhguy also indicated that his ALU was pushed through more than 1.2 million test vectors, ensuring it wasn’t just a brilliant idea on paper, but a functional system that actually works.
In the process, Tyrone went deeper than most students ever do, right down to every logic gate and electronic behaviour, gaining a true understanding of how computers work beyond the “black box” people usually accept as a CPU.
With Phase 1 completed, the next steps include optimisation, assembling the design onto a PCB, soldering, and the challenging work of debugging to refine performance.
Tyrone’s work is a powerful reminder that innovation is not limited by location or resources, but by imagination and persistence.
His achievement also suggests something profound: with enough understanding of MOSFETs and logic, the building blocks of computers have always been within human reach perhaps even long before modern technology as we know it.
Beyond his technical brilliance, Tyrone is also known for speaking up on religious freedom in education, showing that he is not only intelligent, but also principled and courageous.
