[sdiy] How about some SDIY?

[Aaron Bader]

I'm going to give this a shot on the breadboard tonight - the idea is
basically PWM for triangle/sawtooth waves, ie, smoothly morph from saw
to tri to inverse saw by way of voltage control.

It's simple enough that I assume it's been done before. Any
tips/disadvantages to this approach?
