The author revived the dormant wasp-os project to run MicroPython on a PineTime smartwatch, migrating it to mainline MicroPython and improving buildability. The article details the device's severe hardware constraints — only ~12 KB of RAM remaining for apps after the OS and Bluetooth stack — while celebrating the possibility of Python on a $25 smartwatch.
Background
The PineTime is a budget open-source smartwatch by Pine64 that has gained a niche following among embedded developers and hobbyists interested in running custom firmware. MicroPython porting projects for resource-constrained devices remain an active area of interest in the embedded systems community.
