RGB Projector Lamp

RGB Projector Lamp This is the RGB Projector Lamp. The idea is to project figures onto the sealing of your room using Red, Green, and Blue light. A round disk turns periodically, making the projections move as well. To create more effects, an Arduino switches the LEDs on or off. I made videos of this RGB Lamp and posted them on Facebook. Yes, I know it's not the best place for this project, but you can get an idea of how it works by watching these clips. However, please note that these videos are unedited and recorded with my smartphone. To better understand what's happening in these videos, I've sped up the Arduino code to make it more engaging. This RGB Projector Lamp consists of a RED LED, Green LED, Blue LED, stepper driver, 28byj-48 stepper, and an Arduino Nano. All components just click together - no screws or bolts needed. Here are some additional details: You'll need a transistor like TIP20 and some resistors for this project. The LEDs I used are 1W each and mounted on a heat sink using thermo glue. The Arduino gets its power through the USB port. At present, I have created four different disks for you to try out. A blank disk is also included so you can make your own designs. These disks were printed in green PLA with a resolution of 0.2mm and a nozzle size of 0.4mm. If you use the same settings, everything should turn out nicely. The mid (cylinder) part was printed using the "spiral outer contour mode" in Cura. I've also experimented with printing this part in translucent PET-G, but it loses its sharpness due to reflections. Because I don't have a YouTube account yet, I uploaded some videos of my RGB Projector Lamp on Facebook instead. Please keep in mind that I sped up the Arduino sketch for these clips - they normally move at a slower pace.
