[sdiy] Additive VCO

I forgot who sent me this information (thank you, whoever you are), but I
squirrelled it away for later use - and here we are.  

The above link is to a circuit that converts a square wave to triangle by
analog successive approximation.  I've not yet built it, but I think it
might have interesting character, especially while the input frequency is
changing.  It's on my "to build" or at least to try on SBB list.
