In my previous post, I started putting the glockenspiel case together. Now I’ve bolted the glockenspiel harp and circuit boards into the base of the box, and temporarily mounted the handles and buttons. I still need to wire up the buttons.
In other news, I’ve tried out various ways of damping the initial, loud “clank” when a solenoid strikes a chime. A piece of scotch tape on the top of the solenoid had no effect at all; a dab of silicone (which someone else suggested) can make just the right sound, but I’m a little puzzled about how to repeatably put just the right amount of silicone on each solenoid.
In my next post I reflect on how Design Thinking could have improved the project.
