Music From Outer Space Weird Sound Generator

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!

[jamiewoody]

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!

Am a new user of this forum so am appreciative of all the great ideas, tips and general friendliness!

Also am bit of a novice but am nearing completion of a WSG. Has anyone incorporated LEDs to sync with any of the functions? I am imagining the effect......

Just poke around with some.  I'm certain you'll be able to find something worthwhile. Try putting them across the pots.

WSGs are pretty hearty, so you don't really run much risk, based on my experience.

For anyone starting synth DIY experiments with this wonderful little circuit by Ray Wilson, there are set of additional mods you can do to it by Scott Stites, up to the point of getting some voice-like (formant) synthesis. Sounds samples are also available on Scott's site:

Thanks very much for this - looks like some really useful stuff

Thanks for that tip - as a novice, I have been perhaps over-cautious!
