Nice finishing on your matrix too, btw. Are you using plastic cups under your diffuser there?

Uline Kraft tubes

I did this large version too… it was one of the first one’s I did. You can see the tubes here. Before they are all finished and painted. No ping pong ball diffusers here either… Also before I did any programming for the matrix.

would you please share the code this looks awesome!
