      We stuck a tiny wire, called an electrode, that is about as wide as a human hair, into the nerves in a person’s wrist so we could record what a single touch sensor in their finger tip (called a mechanoreceptor) was sensing. We can play that signal through a loud speaker so you can hear what your fingers can feel! 😮

      We were listening to babies heartbeats and hiccups in the womb using a special microphone. Pregnant ladies who participated in experiment liked it as well, as we used loudspeakers too to let them hear their baby.

      We developed an phone application and added sensors to a white cane to make it “smart” this allowed a visually impaired person navigate their environment more safely and easily. We did some trials with this and 3D audio headphones and it was great to get feedback from real users on what worked and what didn’t. We also got to meet their guide dogs.. the dogs are so good at looking after their owners it was really cool project to be involved with.

      It was in high school. We built an electronic circuit to measure the speed of light with a laser led and a mirror mounted at the end of the very very long corridor in my school.
      We managed to measured with reasonable precision, considering the cheap tools we had.
