Dolby SR via MAKE. Collin writes –
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

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.

Sorry, the comment form is closed at this time.
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.
I can see my house from here!
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?
