The Arduino-controlled projector features adjustable red, green, and blue LEDs via three potentiometers, accompanied by reprap-printed knobs. The Osram RGB LED offers a nearly perfect point light source with 30mA per color, allowing for various speed settings and customizable programming. Additionally, the unit includes an exchangeable stencil and a rotating axis for projecting onto walls or ceilings. For further details and images, visit http://www.flickr.com/photos/wizard23/. Assembling this project requires cutting the carlo-projector44_final export.dxf file, with additional help lines and dimensions provided in the carlo-projector44_final.dxf file for modifications. The majority of parts are crafted from 1.5mm cardboard, while the rotation mechanism is made from 2mm delrin. Cardboard snapping mechanisms secure most components together; however, M3 nuts and bolts, along with two 12cm-long M6 rods and nuts, are also required for assembly. The Arduino source code has been uploaded but lacks schematics for the electronics, built on a stripboard without digital design files. A correction for an earlier mistake is available in the xxx_43 files.
