[sdiy] RADCASTle senior design project

[Aaron Lanterman]

Last semester I taught a section of our Senior Design Project class.

I had a team of four students who created a hybrid synth with analog  
sound generating circuitry consisting of Ray Wilson's boards (three  
VCA boards, one VCO, one state variable VCF, and one noise generator)  
controlled via a PIC through D/A converters, etc. on custom boards  
they made. The interfaces uses rotary encoders surrounded by LEDs.  
MIDI input, four preset buttons. Each encoder has its own tiny cheap  
PIC.

It was quite simply the most ambitious senior design project I'd ever  
seen.

They didn't quite get it all the way working last semester - I didn't  
mind since it was so ambitious - but it did make noise. This Spring  
semester one of the students signed up to do "special  
problems" (basically "independent study") credit with me to put on the  
finishing touches.

Enjoy!

We're going to post all the docs - final report, microcontroller code,  
schematics, PCB layouts, EAGLE files, etc.
