Here’s my latest mini project for my “Toy Inventor’s Notebook” column in MAKE magazine. This time a pocket kaleidoscope of sorts: look inside the peep hole of this little cube and see an infinite galaxy of colorful stars.
A super simple one: just a small cube made of mirrored acrylic with the mirrors all facing in. One hole for viewing and a small bunch of round, moon, and star shaped holes in the opposite side. Just butt joints solvent bonded together and seams taped over to prevent light leaking all the edges. Super simple and fun.
I’d like to try a version made of mirrored Mylar, folded up to make the cube. Has anybody had good results cutting thick mirrored Mylar on the Glowforge? Speeds and power settings?
