This is one of the coolest things the Glowforge has enabled for me yet. Like everyone else, my family has succumbed to the mass hysteria of the coming eclipse. NASA made a collection of very cool PDF templates for pin-hole projectors – one for the United States and one for each state.
I downloaded the North Carolina PDF, made some tiny tweaks to separate cuts and scores and make the pin-hole rounder and cut it out on some basic maple plywood. Took me almost no time to wind up with a toy for tomorrow that also acts as a commemorative keepsake.
I’ve said it before but the ability to do this on a whim is truly the Glowforge secret power.
