In terms of drones, or you can consider the application of sensors. Now is not the so-called era of big data, we can consider designing a device to detect some daily data. Such as various bracelets. But in addition to human monitoring, it can also be pets, cars, plants, lakes, weather and so on. Some of them are already being done by many people. You can also try them.

Other projects include integration, miniaturization, personalization or rapid prototyping. A 3D printer is one such example. This concept of rapid prototyping can also be applied to electronic manufacturing, clothing industry, food processing and other fields, and the technical difficulty of individuals is not great, so integration can be done.
