A simple glowing Christmas tree with a flexible filament LED inside. Available in two sizes: one for a 300mm LED filament and another for a 185mm LED filament. The tree has two modes( 3 position switch):Light sensor mode: Glows only at night, consuming less than 2mA (over two weeks of battery life).Continuous bright mode: Remains continuously ON, consuming <20mA (24 hours of battery life). You can make a PCB for this project (gerbers and schematics are included) or simply connect the LED filament to the battery using a resistor and a switch. To charge the battery, use a TP4056 with USB-C and a battery protection circuit. It’s recommended to reduce the charging current to 200mA by replacing the R3 resistor with a 5k resistor.
