Hackit: Laser Cut Your Own Jigsaw Puzzle

If you have a laser printer, you’ve got your Christmas presents sorted out. At least if your family likes jigsaw puzzles. The idea is very simple, laminate a photograph onto some laser-cuttable board, and then run the laser over the outline of the pieces. Bam! Instant puzzle.

The trick is generating the puzzle outline, and of course there’s an online application for that. It’s got options that let you customize the piece count and shapes, and then download the result as an SVG image.

Unfortunately, it’s closed-source and makes the pieces a little bit too uniform for our liking — many of the pieces have exactly the same shape as each other. Are you up to the challenge of writing a better one? We’d love to see it, because the idea of a simple puzzle overlay for laser cutters is too good. Help us get started with some brainstorming in the comments below. How do you go about generating meaningfully unique jigsaw edges algorithmically?

Once you’ve got the puzzle cut out, you can seal up the surface nicely, toss it in a box, and then you’ve got a personalized present. To put it together, we suggest an accompanying DIY pick-and-place tool. (And kudos to [Kristina] for the best headline of 2015 on that one!)

Thanks to Hackaday alum [George Graves] for the tip!
