LEGO Diffraction Grating Projector

at 12:24 pm. Filed under Cool Gadgets, DIY Hacks


I have never seen a project made with a Diffraction Grating before, but this LEGO Diffraction Grating Projector project has a great looking effect. It’s designed by Carl who was featured here before for his RGV Laser System. Those LEGO universal joints have a very wide working angle (watch the video to see what I am talking about).

Thanks for sending it in Carl.
