Today, he is working to bring low-cost, cutting-edge scientific tools to schoolchildren and laboratories in every corner of the globe.
Prakash's small yet powerful design, inspired by a toy music box, costs only $5, and could enable schoolchildren from low-income communities to not only learn about science and engineering but explore and address real-world issues like water quality and contamination.
As part of this vision of reaching more students with the power of discovery, Manu has also created Foldscope, an origami-based paper microscope that costs less than $1. Obama was also impressed by the work of Partha Unnava, 21, of Atlanta, Georgia, who after spending six weeks in crutches, decided that it was time to fix a 5,000-year-old problem. Currently a fifth year Biomedical Engineering student, he helped develop the Better Walk Crutch, which reduces pain and fatigue for crutch users.
Better Walk has since participated in the medical device acceleratory programme Zero to 510, raised $150,000 in seed funding from venture capital groups, and obtained letters of intent from orthopaedic surgeons who want to bring it to the marketplace.
"Today, more than 150 colleges and universities are committing to giving young people more hands-on opportunities to make things," said Obama. "So a few minutes ago, a young man named Partha Unnava showed me the letter announcing that commitment-and of course, it was on some metal that was 3D-printed." He couldn't just give me a piece of paper," he said amid laughter. "It's harder to file, by the way, but it looks cooler." Also invited to the White House Maker Faire was Shubham Banerjee of San Jose, California, who has Banerjee developed a low cost Braille printer, Braigo, using the Lego Mindstorms EV3 set as an accessible solution for blind and disadvantaged people across the globe.
