Reddit reviews Explorabook: A Kid's Science Museum in a Book

Naw, was a decade ago. I took a diffraction grating from this and a regular digital camera, old telescope tube, and some razor blades to make a slit, and wrote some code. Pretty sure it was C# because that's what I was learning at the time. I think the code is gone -- I didn't bother to set up a github account or anything.

To do it right, I'd need a better difraction grating and a camera without an IR filter -- preferably without a bayer filter on it either. Or at least some sort of response curve for the bayer filter. When I figured out it'd be expensive to get something that gives quality results, I kind of drifted off to other projects.

I think it's the Klutz Press Explorabook (one of my absolute favorite books as a kid!)

> Exploratorium

This is no help, really, but I remember having a Klutz book when I was younger that was the Exploratorium in book form and it just made me fall in love with the place, even though I would never get to go to the place no matter how much begging I did. I would do it if only for that childlike sense of wonder that a good science center can instill in you.

That is, if you like science and stuff.

That seems offline familiar, we may have done the same deal and the dog mouth memory, maybe was from a book... Possibly this one: Explorabook: A Kid's Science Museum in a Book
