The version 2 of spider web music box is almost completed. What a hell it was to work by hand soldering those 0805 SMD glued on the wood rim. Really happy it is done now and it works.

This version as 4 red and 4 green LEDs glued to the RIM. They blink with music in an alternating pattern.  The heart beat LED and its limiting resistor are glued on the MCU.  Now the heart beat rate is related to music tempo.

Sorry for bad quality video but I'm not equiped for that.
