Matrix madness, word clock meets matrix lamp


This, when cut from paper, will wrap around the outside of my matrix lantern design. I recommend making one out of black paper for an inner layer to keep the light from washing through and an outer layer of what ever color paper you like. I used black card stock for the inside and red poster board for the outside.

This has the same clock face in two locations. This design makes the time visible from a wide viewing angle. Thus, I used a pair of the cheap 8 x 8 matrix panels and tweaked the arduino code to drive 128 LED vs 64 (i.e. 2nd clock). The panels daisy chain together so that made wiring it up easy. I left a blank column between the led panels ( centered over one leg) . That seems like good spacing. It looked a bit odd when they were butted up against each other.

Added note: there is also a layer of white printer paper under the lettered layers to act as a diffuser.

I am really looking forward to the next time my life slows down a tiny bit, so I can spend some time working on one of these. You are so generous to share them with us!

Outstanding as always. I never would have guessed the outside was just paper.

These are so intriguing! Thank you for sharing.

Thank you for sharing the great work you do.

It is a superb design to be sure. if you didn’t want to use paper you could certainly do a veneer that might match other furnishings. Once I build the light for my pool table i will have a sizeable amount of veneer left :wink:

This is very cool! Thank you for sharing your work!

Neat-O! I have a bunch of extra matrixes lying around thanks to your lamp design so I’ll definitely by trying this out.
