Forum - Week 3 - Breadboarding...

...only with a considerable lack of bread.

For something a little different, Jake and I ran my MP3 player through the ring modulator circuit. The result was quite good, however the video and sound was just typical mobile phone quality. If only we had some water and a waterproof piezo, we could have had the whole shebang. During forum, Jake and I used the waterproof piezo as a speaker inside a plastic cup of water, and picked up the (Nine Inch Nails) vibrations with another piezo jammed underneath the cup. We then swapped piezo roles- the waterproof piezo was the microphone and the piezo underneath was the speaker. The latter worked better, as moving the underwater microphone around in the glass created a variety of timbrel effects on the music (particularly when blowing bubbles through a straw). It was only fair that Reznor got a rest and Tool got a try, so this time we played 'Jimmy' through a ring modulator.
