My wearable circuit is a bag that lights up when a button is pressed. When it's dark at night and you can't see what's in your purse, why pull out your phone flashlight when you could have lights inside the bag already? This circuit is meant to make the task of searching through your bag in the dark easier.
My non-wearable circuit is a guitar guide tuner. Each time you press a string, it tells you what its designated tuner is through light feedback. This is to help beginners figure out which string belongs to which tuner.
