It is great to watch with different kind of music. I got 4 more to build so i can put them in many places.
If you have not had experience building circuit boards with surface mount components it will be a real challenge.
There is another kit that uses thru hole components that is easier to build. It works identical with this one and the number is the same except for the last letter.
It is a fun project and enjoyable to watch
Very compact, with qualty parts, soldering takes some skills. Different modes with IR remotecontrol. I connected 10mm leds on the output and mounted these on the bottom of a white glass sphere, which then create mixed colors to the music.
