My initial idea for the specialisation project was based off working with ultrasound sources to create an installation piece. I planned to place ultrasonic pest repellers that had been tampered with and circuit bent to produce sound in the audible frequency range in a space somewhere in LCC. I was planning to make a quadraphonic piece where, unbeknownst to the students and staff walking through the space, were triggering sounds from the 4 ultrasonic repellers triggered by the motion sensors on them.

In preparing to create this I bought the 4 ultrasonic repellers online. In the description of the product and on the packaging it said it had motion sensors built in as well as a controllable frequency. Unfortunately, when they arrived it was clear there was none of these features included. I decided to tamper with it anyway and see if I could change the frequency.

Once opening up the case it was evident how unlikely It would be to change the frequency. I replaced 2 of the resistors in the circuit with potentiometers and found that one of them controlled the LED light that was attached to the circuit board. The effects of replacing the other potentiometer was less clear. I tried a variety of different resistance potentiometers but none had an obvious effect to the frequency of the oscillator inside.

With the money I currently have and the time I have in which to complete this project, I thought it was best to put this project on hold for now and go a different route. I will try to get this prepared for the second part of the hand in as I like this idea and want to execute it. My work will start to head in this direction more, tampering with audio equipment and creating circuits to produce sound are where my interests lie at the moment.
