Description

This easy to solder kit is based around an UM66T19 melody generator which will play Beethoven's Für Elise on a small piezo buzzer. Once assembled you've created your own music box that will play the song when pressing (or releasing) the microswitch. To complete the set Francois Janssens created a lasercut design to fit the PCB in either an upright piano or a grand piano. These are desgined to be cut out of 3mm MDF and are available in the design folder on Github.

Kit contents

  • Battery holder (Default CR2032, optional 2xAAA)
  • UM66T Für Elise music chip in a TO-92 package
  • Micro swith with lever
  • Buzzer
  • PCB

Assembly instructions

  • pay attention to the orientation of the battery holder
  • In case of the CR2032 battery holder, solder this first
  • Next up is the component with the least height. In this case the buzzer.
  • carefully bend the pins of the melody chip (3 pins TO-92 package) to fit the wider footprint. (This is not required, but will make soldering the chip a lot easier)
  • Solder the switch on the prefered location. Soldering the switch on the NC location will make the kit work as a music box and play music when the button is not pressed. This is the location for the grand piano kit.
