Battery Powered Smart Table Lamp

I needed a lamp that doesn't glare into my eyes or onto the projection screen, while still putting some light on the table for my snacks. Lamp is 15cm tall, using RGB+CCD LED Strip, connected to my smart home via Wifi/MQTT, powered with 4x 18650 Li-Ion battery.

Change lamp color by publishing a message with content similar to "0,0,0,0,0". It's red, green, blue, warmwhite, coldwhite. Values are 0..255. If any of the R,G,B values are >0, WW and CW are reset to 0 to avoid overcurrent situations and weird colors.

All parts should be easy to print with little to no supports. Do use PETG though. PLA will make a brittle lamp.

BOM:
