Very nice visual effect

Mar 09, 2017

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 MCR610

Description should mention no documentation aside from the parts list in Chinese.

This 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.
