Description

Why is it that a novel feature such as reactive floor track lighting only comes in extremely overpriced car packages? My goal is to produce a much lower cost, open source module capable of analyzing audio with a low latency (not visible to the end user), and reflect band amplitudes using low cost LED strips.

Details

I intend to provide a stand-alone, open-hardware / open-software board for driving tri-colour common anode LED strips with audio frequency amplitudes.

Although the current WS2812B addressable strips would open more opportunities, the price per meter is nearly 5 times that of a 5050 SMD strip.

The hardware design is nearly complete, apart from my grand wisdom in designing the ISP header backwards. Software design is proving to be more fun than I had anticipated.

Given that I've named the project Ambuino, the design is currently reliant on the Arduino platform. However, with that, there is always the option to go full AVR, or even PIC.

Here's an early beta test (Warning, Foul Language in some songs):

What a busy few weeks it has been! Double shifts on the job warranted an extended vacation. 2,000 kms added to the odometer, and we're back!
My biggest hurdle currently is trying to increase the PWM rate. Even 1/255 is quite bright on Arduino. As much as I want to avoid adding a 5940, it may produce a more effective light output.
Thanks to those of you who have skull'd the project. It really helps fight against the procrastination.
