2021-10-11 (M) EWC_Panel Timer faceplate

Faceplate layouts can be a simple chore, but I managed to make this a trial. I started with the simplest panel, the timer. In my imagination, it was eight buttons, four up and four down, under four digits. I started with the display and pushbuttons. The display can fasten to the top with four #4 screws, but I plan to use inexpensive tactile switches, and those need to mount on a flat surface. My solution was to cut a slab with corresponding mounting holes that will sit parallel to the face.

I figured I was done designing the top, so I turned to the sides. I planned to add a MIDI port, and I already had a footprint for it. The unit was very compact, but I realized the data port would probably bump into other components inside the enclosure, so I made it wider. Next, I remembered that I didn't have power running to the device, and I considered adding voltage lines to the MIDI cables, but that wouldn't be standard, so I opted for a barrel connector, for which I had a footprint ready.

The next three-dimensional problem I had was how to hold the sides to the box. I have never built a box with interlocking fingers, and they rely on knowing the material thickness, and I'll probably use scrap wood. Rather than guess at laser kerf width and material thickness, I decided I would not print sides. All my components will mount on the top. I'll cut a bottom, but the sides will be open. If I revise the design, I can worry about completely enclosing the components.

The last issue was a panic button. I want one in this project. If I had loads of time, I would make a separate box to do all the unusual functions, like switching melodies across all units, panic, or randomize all the notes. Instead, I'll start with the functionality I need. Perhaps in the next iteration, the timer box will have all the system-wide functions included.
