proof of concept

i've decided that the mixer is not the best way to amplify the signal from the pipes, instead i'm going to build mini-amps for each pipe. that way each of the 4 speakers i'm planning to use will each be individually the sound of one of the pipes. one pipe, one speaker. 4 individual pipes, 4 individual speakers.

 i found this sound mixer, with 5 inputs, in the rubbish!

 this is a rig up for testing 

- speaker at left, mini-amp in the middle (circuit board),

power off to transformer at top, contact mic at right.

this contact mic was made by artist Riki-Metisse Marlow

drawing out some ideas, considered mounting amp on pipe

getting a feel for how the 4 pipes would look with the 4 amps and 4 speakers,
and trying to figure out how to get the power to each amp

decided here to run the power cables up the pipes and into the roof,
creating much cleaner lines in the 'system'

sequence of developed ideas through drawings (left to right)

i'll have to make 2 more mini-amps, as i have 2 left over from an artwork i exhibited last year. and i'll need to get 4 desk lamps. that should be all i need to purchase to complete the work.
