Modules in the second version of the Electronic Wind Chimes were designed to use space efficiently and logically. Logical use meant not putting buttons and knobs above a screen which would block the view while adjusting and efficiency was using the surface space with few gaps. Two arrangements were made, the primary, a secondary. Only one primary module would be built and would not look much like the picture on the left. Five secondary modules, like those on the right image, would be constructed just like shown except the toggle switches and pushbuttons would be swapped.
An acrylic sheet was chosen as the face because it was available and transparent. Using clear material was vital because it meant the screens could be mounted on the underside to remain protected instead of cutting a hole in an opaque sheet of plastic. Drilling acrylic is akin to performing self-surgery.
Before deciding how many modules would be built, the IO of an Arduino MEGA was counted and the IO of each module was counted. This was a rough estimate and threatened to use too many spots, but there was enough room. Every pin was planned and color-coded.
Each module would use a prototyping board mounted on the back of the screen since each module would have its own screen which would keep some of the wires hidden behind the clear plastic. The boards would provide a junction where wires from the controller could be landed then run out to the devices. It would also hold the pull-up resistors for each discrete input and split the power and ground to everywhere it needed to go.
It took a few iterations to make a junction board that would be easy to land everything. Adding long wires for ground and voltage seemed logical, and the third iteration was the most usable.
The rest of the summary posts have been arranged by date.
