Audio Engineer Cable Tester

prusaprinters

I work as the “audio engineer” for my local youth group. After years (possibly decades) of abuse our cables were starting to show signs of age. To make it easier for me to find the bad ones I created this cable tester.It allows for testing3-Pin XLR,NL2 SpeakOnNL4 SpeakOn¼" Jack (TRS / TS)cables.If you get creative with adapters you might be able to test even more cables.I'm using an Arduino Nano as the brain of the tester and a cheap monochromatic OLED-Screen as an output.The full project description can be found on my GitHub. There I have the full Arduino code, and more explanations of wiring and using the tester.
