West African Teen Inventor Visits Harvard, MIT

(ABC News)–He's made a transistor radio, powered his community's FM youth radio
station with homemade batteries, and, most recently, built a larger
studio generator — all by using materials he found in the trash.

At the age of 16, Kelvin Doe, also known as DJ Focus, has been called a
prodigy and a genius. He's the most prolific inventor in his West
African village of Freetown, Sierra Leone.

Doe is the youngest of five children and says he's been inventing
gadgets since the age of four. He gathers scrap metal and other
materials to create electronic solutions for his town. His inventions
have caught the eye of university professors and scientists at academic
institutions in the U.S., including Massachusetts Institute of Technology and Harvard.

“The exceptional thing about Kelvin is he's a very poor kid with very
little infrastructure. He's been able to harvest that talent with
virtually nothing,” said Laura Sampath, manager of MIT's International Development Initiative. “He takes apart and then learns by what he's seeing and can rebuild it, often better than what he's seen in the first place.”

Earlier this year, Doe entered his inventions into the first ever Innovate Salone Challenge — a competition funded and run by Global Minimum Inc., a nonprofit organization founded by David Sengeh and his colleagues during his freshman year at Harvard.

“Innovate Salone is based on the idea that young people can create
solutions to problems they experience,” said Sengeh. “By doing this,
they learn through making, they are doers and makers and not merely
receivers. They participate in the culture of making, form a network
with other makers, and experience the joy of creating.”

The mission behind Global Minimum,
or GMin, is to give young inventors the tools, mentorship and platform
in which to carry out their ideas. The Innovate Salone Challenge seeks
those ideas in the areas of agriculture, education and energy, to name a
few. Teams of three present an idea. Winning ideas are then awarded
$1,500 to make their ideas become reality.

Sengeh's organization put out a call for applications in March. When the
process closed in May, Sengeh and his team had 70 applications from 300
students, trying to solve some of Sierra Leone's most challenging

Doe's project was to create local FM radio stations. He saw how steep
the start-up costs are for local radio stations. Many living in remote
areas are not able to get the news and information they need without

Doe, along with two other students from Sierra Leone's Albert Academy,
came together to build a prototype station. Sengeh says Doe's
application stood out because of his speed in implementing his idea.

“Kelvin had already built prototypes, thus his application was much
stronger than others who were still only at the idea stage,” said
Sengeh. “He had been making different things and his project seemed
definitely feasible, and it had already demonstrated its community

Sengeh knows firsthand the challenges many face in Sierra Leone, having
grown up under many of the same conditions as Doe. After being named a
top student in Sierra Leone, Sengeh was able to study at Harvard, and is
now earning his doctorate from MIT. Sengeh says he created GMin to give back in the same way others before him gave.

The Innovate Salone competition was modeled after the MIT Ideas Challenge, where applicants are encouraged to present and develop ideas that will change the world.

“In my life, I am very grateful to all my mentors,” said Sengeh. “I just
wanted to share with the young innovators what I was exposed to. I knew
they would learn a lot even within a short period of time.”

Winning teams are paired with local mentors within their community, as
well as professionals in the fields of chemistry, physics and

Sampath is part of the Visiting Practitioners Program at MIT's International Development Initiative. She heard about Doe's inventions through Sengeh.

“It's the first time a 15-year-old has gone through the MIT Visiting
Practitioners Program,” said Sampath. “That program brings in mid-career
professionals. Fifteen years old is not the average age of people who
are visiting practitioners. There's never been anyone even twice his age

Doe describes himself as a self-taught inventor who looks at an object,
breaks it apart and then rebuilds it completely. He's built his own
amplifiers and repurposed audio speakers.

“Kelvin doesn't own a screwdriver,” said Sampath. “He is a prodigy.”

Freetown, Sierra Leone

Freetown, the capital of Sierra Leone, is home to one million people. In Doe's community, there are few resources.

“It is not one of the wealthier areas so the challenges are the same across these communities,” said Sengeh.

Sierra Leone sits on the western coast of Africa is home to over five million people.

From West Africa to the Western World

When Doe and his teammates were selected as finalists, they were invited
to travel to the U.S. in September. They took part in the Maker Fare,
a festival for inventors in New York City, and spent time meeting
students and professors at MIT and Harvard. The three-week trip was made
possible through partnerships with Africell Sierra Leone, Make Inc., and MIT.

This was the first time Doe left Freetown to travel to the United
States. Many helped make Doe's visit comfortable, including hosts like
Kate Krontiris, who works for Reboot.org — an organization at the Maker Faire.

“He was tremendously focused on his inventions, improving them and
making them do different things,” said Krontiris, panel member for the
Maker Faire. “He's also sort of a regular person who came to the US for
the first time. I think it was exciting and a bit overwhelming.”

Despite the culture shock, Doe's mentor in Sierra Leone, Francis
Koromah, said he could see how the experience in the states affected the
young inventor.

“When Kelvin came back from the U.S. it was wonderful for us,” said
Koromah. “His interaction just transformed him into something. It's a
massive difference — a big change and it's wonderful.”
