Laser space nebula projector (Patreon)

Inside a spaceman laser nebula projector

This unit is actually pretty good. It produces an RGB nebula effect with a laser starfield. The design is solid and functional, with a neat magnetic swivel head for aiming the output. But I strongly recommend against using the laser option where people can view it directly, as the laser is quite bright and probably has a high invisible infrared content. For power the unit uses a USB supply with a current of around 500mA. The circuit board is logical and the optical system uses a novel cradle for edge-driving the nebula (distortion) disk. I mentioned Optikinetics who are an iconic effects projection company who originated in the disco era, and are still actively producing specialist effects projectors for prominent entertainment venues. (I've installed their equipment in Disney theme parks.) If you're looking for an original oil wheel, kaleidoscope effect or this nebula effect on a bigger scale, then Optikinetics are still the professional choice.
