CBHH task2 – The Laying on of Hands and Hacking the Clock
This first task was to take apart and circuit bend a radio or musical toy of our choice. I decided to use a simple toy that had a simple audio buffer with multiple samples to create a larger range of sound.
I then carefully took apart my toy and experimented with bridging different locations on the board with my finger, shorting the circuit to find the right places to make my modifications. The bridge which seemed most effective was between the first to pins on the buffer, which correlated with pitch. I then soldered a 100k potentiometer in between the pins.
I then put back together the insides and drilled a whole in the front of the case for the pot to sit.
I then found a second bridge that I believed was effective, which was between the six and seventh, so I soldered another 100k pot there, which seemed to create a fazzing effect. however once I had reassembled the toy, this mod did not seem to work. below is pictures of this attempt anyway.
If I have more time I will try and redo this modification.
Amplifying the toy
task three was to the amplify my chosen toy. To do this I Tested the connection by attaching a separate speaker to the connections of the toy’s speaker. I then soldered to cables to the toys speak connections, so that the internal speak still worked if it was not being amplified. then connected the positive and negative cables to a mini jack connector, so that I could plug most speaks straight into my toy. I then drilled a small hole for the cable to run out.
here is a small video of the circuit-bent toy working.
