Music From Outer Space Weird Sound Generator

[matt the modulator]

i wish i had not have seen this aim going to have too make another WSG with the 74C14N in it i really like the different sound it makes!

i wish i could see more of a closer layout of the pcb of this thing...

i notice only about 2 pins on the cmos and 1 pin on the opamp are used. i know i have tons to learn, but it seems like a lot of chip to only use that many pins...lol! also, for some reason, the schmidt trigger data is much harder to follow than a 555 or 556!  i just want to understand the logic of the pins...what is voltage in? what is output? etc. i just need some example layouts using these!

some more 40106 stuff here triangle and square-wave outputs

40106 oscillators are loads easier to make than 555 timer oscillators. Also each chip has the ability to make 6 individual oscillators. These can all cross modulate each other for loads of crazy wrongness.

Check out this dudes page for more info.

does this mean i have the hard work behind me?!

THANK YOU for the "sea-moss" site! finally, one that explains it in layman's terms! so, each pin is a voltage in or v-out?!!

fun stuff!

again, thank you for your help. i put a schmitt trigger on my breadboard, and basically started experimenting with different caps, resistors and a diode or two. i used a couple of 500k and a 100k pots, and i came up with a  pretty cool sounding synth!

so, something else under my belt i have learned!

Love the WSG.  I've built 3 of the original versions.  On the last one, I added inputs, as described here:

I think they're referring to the newer version, but its doable with the old one too.
Very easy and worth the extra parts.

i am going to try to actually build my synth as a final product today. mine is similar to this wsg model, but, without the opamp. there are about a million sounds one can get from a hex schmitt trigger though!
