I think I can make something similar to this DIY light-controlled tremolo: https://www.youtube.com/watch?v=31pgOcLlCo0
Or the updated version of the same idea: https://www.youtube.com/watch?v=l-VKapfaKg4
My main question is, can anyone make a recommendation between using the fan or the DC motor to move the disc? Is the fan faster than the DC motor? Would one of them spin up to speed faster than the other? Which one would be easiest to mount the other necessary pieces on? Which one would be more reliable?
At this point I'm thinking of doing a pretty bare bones version of the original idea. Here are the other bits I was thinking I'd need:
microphone (in input mode) or a series of other sound generating bits
dimmer (to control fan/motor speed)
I could use an external light source or maybe one of the various LED bits, but I'm not sure which one. Any recommendations?
Is there anything else I might be forgetting?
