Working prototype of a simple bat detector using analogue circuitry, designed to fit inside an altoids tin.
The bat detector allows you to hear the ultrasonic echo-location signals of bats, and so produces an unusual interaction with an otherwise overlooked and hidden part of the urban ecosystem.
The bat detector is also what I term a makeshift: a self-made designed object, based on the idea of a prototype that is kept ‘open’, ready to be adapted to new circumstances and uses, the parts easily reused for other things when it is no longer found to be of use.
Such a design might form part of a practical and experimental self-education in designing and making, focusing on prototype object–interactions.
