WearPico: An open source smartwatch based on Raspberry Pi that is relatively easy to assemble

The Raspberry Pi is available in different variants. With the Raspberry Pi Pico, a particularly compact version is also available, although this board is more of a developer board than a single-board computer. The WearPico from maker Umut Sevdi is an open source project that can be assembled accordingly. It is also possible to modify the project as well as to collaborate on it.

The model is based on the compact Raspberry Pi Pico W, which also has an integrated graphical user interface. The range of functions corresponds to that of a plain smartwatch; for example, it is possible to display notifications and control the media content of a connected smartwatch.

Operation corresponds to the conventions of the device category and is primarily carried out via touchscreen; not only individual inputs with the finger are supported, but also touch gestures. Some watch functions are also supported, such as setting a timer or using a stopwatch. The recording of temperature and tracking of health data are also said to be possible. An acceleration sensor is installed as well as a vibration motor, which records the number of steps taken and allows for incoming notifications to be displayed haptically.

Umut Sevdi documents the project in detail on GitHub and also provides the corresponding software. Sevdi uses C as the programming language and has also published extensive scientific work on the smartwatch.
