I was inspired by Mohit Bhoite’s electronic sculpture projects, particularly this one featuring a 7-segment display. I don’t have that caliber of soldering or programming skills, but Adafruit’s CircuitPython looked like a good way to quickly program a small project and the ItsyBitsy M0 Express had capacitive touch capability to easily provide inputs. I used the RTC+SD Featherwing as the middle layer between the ItsyBitsy and the 7-segment display because it has a double row of headers and the inner set of headers just happened to match the width of the headers on the ItsyBitsy M0. I made 1:1 scale drawings of the boards to plan the bends in the brass rods, and actually used the lines on the page to get the bends to the correct angle to hold up the 7-segment display.
The build came together almost exactly how I envisioned it. After I started testing the display I found that the LED segments were hard to see, so I put a sheet of dark acrylic in front to cut the glare.
