A DIY solar-powered sensor light featuring a 3D-printed waterproof housing. The housing consists of a main body and an mounting bracket, with pre-drilled screw holes and a slot for the solar panel to facilitate outdoor installation and secure component attachment. Inside, there’s a built-in lithium-battery compartment and a dedicated mounting area for the sensor control board, with wiring neatly concealed and organized. The solar panel is a standalone module that connects via a side-mounted interface on the housing to charge the lithium battery; the control board integrates light-sensing and motion-detection functions, while also protecting the circuitry from weather exposure. During the day, the solar panel charges the battery, and at night the light automatically turns on, eliminating the need for plugging in and incurring zero electricity costs—making it ideal for use in courtyards, stairwells, and other settings that require low-power outdoor lighting.                                                                                                                                                                                                                                                                                                                                              ......
