Omkar at age 6 became curious about electronics. Fast-forward 2 years and at only 8 years old Omkar had designed and created the O Watch. The O watch is an open source arduino based smart watch that comes as a kit and enables kids to not only make their own smart watch, but also learn about 3D design and coding. The cases can even be customized and 3D printed at home! A sensor board can be added which can measure atmospheric pressure, temperature, humidity and even function as a compass. Now if that isn't impressive, then what is?!
Check out this video from 2015 of Omkar explaining the O Watch:
