The main difference with my new design is how the EL wire is controlled. Before, I had the entire box controlled with an analog circuit. I like to make things analog whenever possible, and given how simple a graphic equalizer is, it wasn’t much of a challenge. This presented a problem this time around though.
The new glasses will be set up on a display for a silent auction, and keeping in line with the “silent” aspect, there won’t be any loud music to show them off. This makes them a lot less desirable as a simple description card really can’t convey how cool they are.
This meant that I had to incorporate some kind of “demo” mode which eventually turned into making a full-on digital sequencer that can either react to music or play back pre-recorded patterns.
