pretend i don't know anything about programming arduinos or designing circuits. i have a challenge for you, and here's how i want this to go: i explain what i want to build, you help me with the schematics and code, i put it together myself, it works, i send you some sort of compensation (i.e. gift card to newegg? i dunno, we can talk about that later)
so here's the deal. i'm in a weird 80s pop funk band. i want to put together a jumpsuit with a large amount of EL wire sewn onto the outside, which reacts in realtime to environmental sounds and is controlled and powered by a small pack that will fit into one of its pockets. that's the basic concept, though i do have some additional requirements:
1. power supply must provide at least 90 minutes of continuous use
2. there will be 3-6 different colors of EL wire
3. each color of EL wire will be activated by sounds within a certain frequency range (i.e. red wire triggered by sounds below 200Hz, orange wire from 200Hz to 700Hz, etc)
4. the intensity of the EL glow will directly correspond to the intensity of the ambient audio within those frequency divisions
5. there needs to be a way to fine-tune the sensitivity of all the different frequency ranges, as well as a "master" knob that adjusts the sensitivity of the system as a whole
SO
the arduino needs to receive ambient audio signal, that signal needs to be split into different frequency ranges, the amplitude of signal in each frequency range needs to be expressed dynamically by pushing a corresponding amount of power through its color of EL wire, and all this needs to happen in realtime (i.e. with as little latency as possible). also i need the ability to tweak overall system sensitivity on the fly, because too much signal means the EL wire is always on, and not enough signal means nothing happens
i can afford to drop up to $150 on components, not including the jumpsuit itself. i just need someone to design the schematics and code for me so i can build the thing because i generally learn by doing. any takers?
