Sculpt-O-Sound presents: WOPR-O-Matic.

This is a LED-panel I’m working on mounted with some pieces of card board in my rack to see how it fits. It is meant to fill the hole in the bottom which I’m not using for modules. The pic is a bit dark, but if you look closely to the left and right of the display you see Apollo, Greek god of music. That felt appropriate somehow. Once all dimensions are OK I will make a nice panel for the display.

I call it WOPR-O-Matic.

I’m sure to some of you WOPR will sound familiar.

The initial version was controlled by an arduino nano. But I soon ran out of memory progamming it with patterns for the 192 LEDs once I went beyond pure randomness. Now it is controlled by a BluePill which has way more memory space and the patterns are what you might expect from a WOPR. It has a clock input, so that it can be synced to the modular. It consists of 104 red LEDs and 88 yellow ones.

You can see some pattern movement in a short video I posted on instagram.

The design is not completely finished yet, but once it is, you can find the design files and software on my github.

It looks great !!

Always remember Sam video, where he was drilling holes without measuring, saying “measurements are for mathematicians” :grin:

I’ve found that making a picture using a camera of the LEDs is difficult. They often saturate the optical chip. Changing the sensitivity helps a bit but this results in the rest of the picture becoming rather dark. Here is another one of the card board mockup showing the side panels a bit better.

For the final version I think I will use plywood and a K40 for the engraving and cutting of the 192 holes for the LEDs.
