Dan Meeks shares his design idea on edn.com:
This Design Idea presents a low power short circuit finder that capitalizes on the ear’s sensitivity to changes in frequency. The heart of the circuit is a voltage-to-frequency converter (based on Linear Tech’s AN45, Figure 13, by Jim Williams), which converts millivolt-level DC voltages to a wide range audio frequency output.
