The UCL - Ultimate Chemical Light - Desk decoration

thingiverse

Here's my recently wrapped-up project: The UCL (Ultimate Chemical Light)! Even though this object doesn't involve any chemical reaction, I used old reformulated tubes with a diameter of 22mm and found a way to use them in the coolest manner possible. The four tubes are illuminated by four LEDs that are perfectly positioned to diffuse the light inside the tubes, and they change color! I designed the UCL_body in Solidworks and printed it. I utilized four RGB LEDs similar to these: https://www.amazon.com/dp/B011BGA7VI?th=1 An Arduino Pro Mini like this one is also used: https://www.aliexpress.com/item/1pcs-lot-Pro-Mini-Module-Atmega328-5V-16M-with-Arduino-Compatible-With-Nano/32672852945.html?spm=a2g0s.9042311.0.0.283c4c4dJrcD2q Additionally, a switch and an FTDI module are needed to upload the sketch to the Arduino. Since the Pro Mini has only six PWM ports, I simply connected one color of two LEDs on the same pin to control them. It works fantastic! This project can also be achieved using Neopixel LEDs or another controller. The Arduino code is included in the files. Good luck with your own projects, dear Maker!
