Design files for the Bat Listener ultrasonic detector kit
The kit is available to purchase here: https://www.curiouselectric.co.uk/products/bat-listener-2016
This repository holds the design files for the PCB, the enclosure and the instructions
The PCB files have been designed using KiCAD (http://kicad.org/) which is open source, multiple platform and free to download.
The Enclosure design files have been produced using CorelDraw (a paid for program) but are aklso available as .dxf patterns for cutting on a laser cutter.
