[sdiy] Rene's VC-LFO

[harrybissell]

Hiya kids.

Just built Rene's design.  The "improved" buffers are greatly
recommended.

Some additional thoughts...

There are three 'left-over' 4069 inverters. If you tie those to the
three LFO outputs, you get tri-phase square waves.  There are also
three 'lef-over' 4093 NAND gates... you could use them to gate
the square waves on/off... or you could combine those square waves
for even more waveforms.

I have not tried the 4093 trick yet. I suspect you will get three,
negative
going, non overlapping pulses.

Think outside the box !!!
