AS1424 Music Spectrum Flashing LED DIY Kit

It uses a 32-bit high-speed processor to capture every detail of the music and provide a dynamic display. The system is split into twenty-four frequency bands with each band broken into fourteen levels four of which are red.
This is an electronic kit and requires the ability to solder and some electronic knowledge. The electronics are enclosed in a Perspex case. It is powered by a USB cable. Input is by microphone or line input.

The range is linear by 150 Hz steps from 150 Hz to 3.6kHz, it could looks weird because spectrum analyser are usually logarithmic' steps and range from 40Hz to 20Khz but it's a smart approach in fact.
The effect is centered on voices and (most of) musical instruments, so it's a very nice visual effect, didactic and amusing.
The Spectrum analyser is very precise and reacts in a snap, the kit is not very easy to accomplish because of the small parts and i made it with the help of an USB microscope in 2 days (maybe in 8 hours total), a bit of glue is needed at the end to fix the box.
The final result is very impresive and nicely finished with the smoked black box.
Very nice result laid on my Marantz MCR610This item is sold under many various brands, names, and styles.
The hobbyking price is the lowest I've seen.
One thing mentioned in every listing (except here) I've seen is a note that "no English documentation available". I probably wouldn't have purchased this if I knew that .
There are YouTube videos that will probably help, I haven't watched them yet.
The Chinese partslist that comes with this kit is easy enough to figure out without needing to translate anything.
