Kelvin, AKA DJ Focus, helped create a DIY youth radio station made from discarded consumer electronics salvaged from local garbage bins. He designed his own generator to power the station’s amplifier and other components. The station’s 12-volt generator is made from a home-made battery which in turn is charged by broken DVD players. In his spare time, Kelvin DJs at kids’ birthday parties...Kelvin is one of the finalists in the inaugural Innovate Salone 2012 high school invention challenge in Sierra Leone organized by Global Minimum. He presented his work on Maker Camp this past summer. In addition to his appearance at Maker Faire, Kelvin will also be a resident practitioner with the MIT International Development Initiative. And, oh yeah. He will also be a guest presenter at Harvard School of Engineering.
