2019-11-19 (Tu) Electronic Wind Chimes EWC_Presenter

This device looks all right sitting on a table, but I may have a situation where I want people to control it without being able to touch all the buttons. The last two days demonstrated that the software was programmed to recognize these inputs, so today, I wanted to build something specifically for hosting a potentiometer and a switch.

All of the parts came from my stocked material. The stand is from a cheap charging cradle that I harvest the wiring from a long time ago. The potentiometer and cap were from a surplus store. The wires and pushbutton were ordered awhile ago.

I drilled a couple of holes in the angled face of the stand to mount the switch and potentiometer. I wanted to center the switch on the right side, but it had to go higher to avoid colliding with internal structures. The potentiometer needed lots of clearance around it and to accommodate for the dial. I added a pull-up resistor to the switch. The resistor was not necessary, but now this whole thing can be used in other projects.
Internal components

Before I sealed up the enclosure, I tested the electrical connections and they both worked as I had hoped.

On the inside, I needed to keep the wires from coming loose, or worse, tugging on the solder joints. Hot glue held everything in place, but I did not use a hot glue gun; I heated the end with a torch and dobbed the melted end where I wanted some glue. This got the glue hotter than a cheap glue gun and the fluid should have contacted more surface area in the nooks and crannies.

Some of the plastic structures inside had to be cut away, but those were not visible from the outside and only relate to this enclosure so I did not photograph them. I am happy with the appearance of the module, and I think it exemplifies what a user should press without needing directions.

Unfortunately, the knob and button do not work at the same time, so perhaps in noodling mode, if the device senses a remote switch, it could look at the potentiometer for velocity.
