Recent threads have got me thinking a bit about performance aspects of what we do. I’d like to incorporate something visual into my rig that somehow helps an audience connect with the sound. “Sound reactive lighting” sent me down a rabbit hole of DJ gimmicks (the RGB lasers were maybe the highlight of that web surfing session) and left me with this desire to do something visual to express certain qualities of the audio I’m generating, but in a way that feels decidedly organic and low tech.
Is there a nice way to voltage control a simple dimmer for an Edison socket, containing an incandescent bulb? If you had to DIY it from scratch, what would you want to keep in mind?
