Kelvin Doe: The World's Youngest Self-Taught Engineer
Mahanoy City, PA
In Sierra Leone's capital city of Freetown, a young boy once scoured trash bins. He wasn’t looking for food or toys, but rather spare parts, which Kelvin saw as opportunities. Using these parts, he built electronic devices like batteries, hand-powered generators, and more. He also helped fix his friend’s electronic devices and made a difference in his city by using his batteries to light up people’s houses. This kid was 10-year-old Kelvin Doe, born in 1996 and considered the world’s youngest self-taught engineer.
Kelvin Doe has always had a passion for inventing. He turned old wires into power cables and learned as much as he could about any piece of technology he found. He taught himself to do intricate things with little resources or help, by taking things apart and reverse engineering them. The more he made, the more he learned.
His city is a large one, with centuries-old stories and a lot of history running through its walls. It’s mostly known for its beaches and historical role in the transatlantic slave trade and is home to the King’s Yard Gate, through which former slaves walked to freedom. Despite the city being an important symbol of emancipation, there was barely any electricity and constant power shortages. “Lights will come on once in a week, and the rest of the month, dark,” Kelvin recalled. Seeing this struggle in his community, he was determined to create his own battery to shine a new light. His invention not only sparked the bulbs in people’s houses, but also new solutions to problems he saw daily.
David Sengeh, a PH.D. student at M.I.T.’s Media Lab, met Kelvin at a Summer Innovation Camp that he ran, which challenges kids to think about and solve problems in their community. Kelvin’s team applied to build an FM Radio Station for community empowerment. In his community, Kelvin was called “DJ Focus” because he believed that if you focused, you could design an invention perfectly. M.I.T. later invited Kelvin Doe as a guest resident for 3 weeks because of the differences he made. David arranged Kelvin’s visit with funding. He wrote VISA letters, found places for Kelvin to stay, and invested in Kelvin. “Unless we have a host of young people, who can think, at any given point, that here’s a challenge, here’s a problem, and it’s an opportunity to solve it, there won’t be a steep growth in national development,” said David.
From there, Kelvin traveled around the States on a busy schedule to learn from others and share his ideas. One day he’s in New York, the next day he’s in Cambridge. He spoke to the president of Harvard University and worked with Mark Feldmeier, a researcher at M.I.T.’s media lab. He learned more and more, as well as adjusting his FM radio station.
“I want to help my family, to provide a facility for them.” Kelvin expresses. “Whatever I’ve learned here, I will share it with my friends, colleagues, and loved ones and do it as a team.” Kelvin would go on to start up his own tech company, KDoe-Tech Inc., where he designs and sells consumer electronics, reaching his goal of helping his community. He also founded the Kelvin Doe Foundation, a federally registered not-for-profit organization in Canada with a mission to provide creative spaces to nurture communities, ignite a culture of innovation, and inspire civic engagement. Collaborating with Omnivoltaic, his latest project is the KDoe Light, which is a solar light and phone charger with 165-lumen output and 30 hours of runtime at 25 lumens. Other than this, he’s been using his high profile to shed some light on, not only his community, but the entire world by highlighting political issues.
