After putting the finish on the wooden Glockenspiel case, I reassembled all the electronics, mechanics, and the box hardware (hinges, etc.). It works great! See my Arduino Robotic Glockenspiel Complete Demonstration video.
Ok, I still want to adjust the amount of silicone on each solenoid, to smooth out the sound, eliminating the clanking on all the chimes…but that’s for later.
As a reminder: the sources for the Glockenspiel are on the Glockenspiel Github site.
