Leds Mount
How can I mount LEDs on fan blades and have them receiving a signal?
I have to come up with something cool to build for my final project for Circuits this semester. I would like to build a fan that you can plug your music player into, and it will play it. On the blades, I’d like to have a VU meter made of LEDs that, when spinning, creates a circle that bounces with the music (i.e. get larger and smaller with the music).
So to achieve this, I need an IC that is receiving a signal from the output of my amplifier. My problem is, how can I have the LEDs mounted on the blades and allow them to still receive this signal? The problem being, if I put the circuit on one of the blades, then the signal wire will get twisted and break. If I mount the circuit elsewhere, then the wires connecting all the LEDs to the IC will twist and break. Is there a solution to this problem or will I just have to come up with something else?
Go wireless with a simple infrared circuit (like a TV remote control). Transmit and receiver modules are cheap to build or buy. Power the LEDs and circuits on the fan blade with batteries. Be sure to balance the weights so there is minimal vibration.
