Spinner Control Case

Açıklama

Spinner Control Case A case for a spinner control for retro arcade games. A work in progress. Arduino source code available on GitHub (https://github.com/opcow/spinner_control_case) The case lid can be flipped for right handed or left handed spinner operation. The button assembly uses micro switches taken from an old mouse. RIP MX518. You served me well. All parts were printed with a 0.4 mm nozzle. All holes were sized for threaded inserts for M3 and M2.5 screws. STEP files are provided if you need to make adjustments. I've included a fit test model for the microswitch slots that can be printed before printing the full microswitch carrier. You want the switch to fit snugly, but bear in mind that if it the fit is really tight then it's going to force the sides of the slot outward making the adjacent slots even tighter. The optical encoder I used does not tolerate less that 5v input. My Arduino was supplying a bit under 5v and I was testing using the full length leads to the encoder. When testing without the boost converter the encoder did not work. My converter output is set to 8v. Optional Things I chose to mount the MCU with header pins installed because it helps to hold it solidly in place. The MCU gets sandwiched between the MCU cover and the mount which is screwed to the bottom cover and the whole thing is held together using a zip tie. There is also a mount meant to be used without the cover, just a zip tie holding the board in place. If you use a different MCU than the…
