Finished
#soldering my
#VCO #perfboard. It is calibrated to 1V/Octave and outputs sawtooth, square/pulse, and triangle waveforms.
The heart is a
#CD40106, using only one of the inverted Schmitt triggers. I tried adding more, but couldn't fit them properly. Maybe if I left out the triangle wave output, which would remove the upper
#TL074.
My power supply board is getting full, I should add a few more sockets.
