Maybe you've created your own AR program for wearables that shows the definition of a word when you highlight it IRL, or you've built a personal calendar app for your family to display on a monitor in the kitchen. Whatever it is, I'd love to hear it.

I put together some operational amplifiers as filters to measure skin voltage and infrared absorption then used machine learning to learn to identify me and to measure blood pressure, pulse rate and oxygen saturation.

I was close to predicting/estimating blood sugar when I lost momentum and also had a few errors making up PCBs.
