Nice perfboard

Wandering the halls of Wikipedia, I came across this jaw-droppingly complex File:Dolby_SR_breadboard.jpg (stripboard, to be precise). The unit was built as a prototype Dolby SR noise reduction circuit and was photographed by Mr. Gregory Maxwell at the San Francisco Airport Museum’s History of Audio exhibition. A few pics from the 2006 exhibit can be found over at Stereophile

  1. I learned to not ask my dad for help with math homework as a kid because he would make me take a new piece of paper and start over every time I erased a mistake.

    I know i’d never get far enough along on such a project without throwing it out to start over again.

    I hate perfboard. As obsessive as I am over the aesthetics, one pad would lift from overheating and it would all be over.

  2. I can see my house from here!

  3. Wow, talk about tweaking. I counted maybe two dozen switches and who knows how many trim-pots on the board.

    You’d think the sprawling layout would make it prone to noise and other problems, but maybe at audio frequencies you can get away with it?
