Battery Powered Smart Table Lamp

thingiverse

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: - print each part once - 4x 10cm LED Strip https://www.led-konzept.de/RGBCCT-LED-Streifen-24V-197W-m-RGB-CCT - 4x 10cm Aluminium profile https://www.led-konzept.de/LED-Alu-Profil-FLEX-mini - 4x 18650 Battery holder https://www.amazon.de/gp/product/B075TZF7NN/ - 1x XT60 plug (male) - 1x JST-XH balance plug (female), 2S (3 pin) - 1x 24V Step-Up converter https://www.amazon.de/gp/product/B079H3YD8V/ - 1x 3.3V Step-Down converter https://www.amazon.de/Pololu-Step-Down-Regulator-Efficiency-2842/dp/B07KHPQLZT/ - 1x ESP8266 ESP-12 Barebone https://www.amazon.de/TECNOIOT-ESP-12F-ESP8266-Upgrade-Expansion/dp/B07WR96QDG/ - 5x IRLIZ 44N mosfets - 5x 10kOhm resistors for the mosfet gates - 5x 1kOhm resistors for the barebone ESP - 1x 100nF ceramic capacitor for the barebone ESP - 1x 22kOhm resistor for battery measurement - 1x 2.2kOhm resistor for battery measurement - 4x M3x16 screws - 4x M3 nuts - thin insulated wire (like 0.1mm PU-coated transformer wire / enamel wire) for the LEDs - regular insulated wire for the rest of the wiring - generic glue for fixing parts together like the plugs ...and a USB serial interface for programming the ESP.
