HandlyUpdates
Short, sourced notes from the daily log: robot arms and LeRobot first, then dev boards and ESP32, then hands-on tutorial picks. Every note names its source and the date we read it. Nothing here is a hands-on review unless it says so.
Robot arms & LeRobot
LeRobot v0.7.0 rebuilds install, training, inference and hardware layer

Dev boards & ESP32
