The spider web music box version 2 is now completed
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.
Update readme.md on github to add photos.
Not satisfied with the result of this first iteration, started working on iteration no. 2.
Will replace through hole components by SMD and mount them on top of octogon rim.
I added a video on youtube to show sculpture in ac tion
The circuit is assembled on the cone of a 4" speaker. The microcontroller, an 8 pins SOIC, is suspended in center with 30 AWG wires going out from it to
circumference. An octogonal wooden rim glued to the speaker support the components and the spider web.
On power on a tune is played then the microcontroller fall asleep. In sleep mode it draw less than 1 µA.
Pressing resset button wake up to play the next tune in the list then fall asleep again. At each press of the reset button the next tune in play list is executed. At end of list the pointer is reset to beginning.
