I thought I'd kick off a holiday 2014 thread with my latest DIY hack.
I'm planning a VU Christmas tree. That is, instead of syncing my tree's lights with a song, I'm going to drive them with an electret mic + a VU meter chip, so that they light up in response to the audio level in the room (like a graphic equalizer display, or KITT's voicebox). This way, they'll also react to Christmas music. I have several chips in my parts bin, so I may filter the lights to multiple channels. I'm planning now, so I'll let you guys know. I'm really interested in doing these projects without microcontrollers. I'll keep you posted.
