Self-Taught Teen Prodigy From Sierra Leone Wows MIT Engineers

The latest installment of the THNKR's Prodigies YouTube series highlights Sierra Leone teen Kelvin Doe, who is visiting the U.S. as a guest of MIT.

The 15-year-old is a self-taught engineer, who has never taken an engineering or electronics class. Combining scrap metal, baking soda and acid, he created a battery to power his family's home. He also broadcasts news and music as DJ Focus on the radio, using an RF transmitter he created.
