I’ve made some good progress since last week. I’ve mostly developed two areas of my project.

The first area is that I’ve improved the precision of the light blips a bit to more accurately correspond with the actual notes or sounds they’re supposed to. Before I had some issues with noise causing some of the blips to light up when they shouldn’t, so I’ve made the spectrogram a bit smoother and I’m able to track certain notes now a bit better.

The other area is that I’ve finally come up with a plan for the enclosure for the LED matrix. I’ve ordered some translucent acrylic plastic sheets, and the idea is to cut them and glue them together to make a nice flat diffuse surface for the light to come through. A sheet of acrylic will be mounted over the LEDs so that the glare you get should be reduced significantly. I tried diffusing the light using just some paper napkins, and it looks a lot better. You can’t even make out the individual LEDs any more, they blend together into really nice looking blobs of light. Hopefully the acrylic will provide the same effect, but be more permanent.

Sorry I don’t have any images or videos or anything for this week, but there isn’t much visual difference from last week, and I’m getting fed up using my phone camera. Next week once I have the final product done, I’m going to use some actual good camera equipment in a nice dark room to record the display, and I’ll use some actual video editing software to put the audio on it. Looking forward to seeing how it turns out!
