This project involves designing a portable device that can inject a 1kHz sine wave signal into a 100V audio line to detect short circuits. The device should be compact (around the size of a smartphone) and include LED indicators to show the status: a green LED for normal operation and a red LED for short-circuit detection. The device will be powered either by a switching power supply or rechargeable batteries.

Welcome to your new project. Imagine what you can build here.

A simple fixed linear voltage regulator board that can provide 3.3V up to 1A output and could operate down to 1V input-to-output differential. #firstpcbFlux
