LEGO Diffraction Grating Projector
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.
