It is possible to sync 2 simple VCO from a 40106?

[andrewF]

yes, maybe.....
but its hard to give any more details unless you do

lorenzo we would need at least a schematic of the simple oscillators
you plan on using to be of any real help here

ahh sorry... 2 of this:



MFOS Simplest Oscillator On Earth

the WSG has a sync like feature, by adding the output of one oscillator to the input of the schmitt trigger by means of a diode.

[bod]

you can also do it with the 4093 ic, which has 2 inputs for each gate, one of which is tied to the positive power line when used as an oscillator in this manner, but by putting the output of one oscillator to the input of another it creates a sync effect. as the 4093 has 4 gates, you could have some seriously wonky sync effects with 4 oscillators syncing each other in a ring.

(edited for me not being able to type properly....)

the psuedo ring mod wont oscillate on its own (as far as i am aware) but a cool wee module for a drone synth.

if you look at the schematic at the bottom of this page http://www.vidiotsquad.com/synth-stuff/simple-oscillators/ you'll get the idea of the 4093 nand oscillator.

there are only two gates used on that that one, but if you link them in a ring, so the output of the last oscillator goes into the input of the first oscillator, you should be able to achieve the ring sync'd nonsense, you just need to take an audio output from one or all of the oscillators and sum them together as well to be able to hear it, while they all modulate each other.

build two and then use the psuedo ring modulator and you'll have something even stranger to listen to...

Oh thanks... I will try!

I just have 4011 so I think I will use it for pseudo ring... but double syncronization is seems to be interesting!!


IMG seems to be corrupt... here is the link CLICK
