i discovered, while breadboarding an atari punk console, more simple circuit, with only 1 or 2 pots...adding a diode makes the cutoff rate faster, and the tones are even MORE 8 bit video game like!
-
these things are fun and easy! i also learned how to build two of these onto one circuit! it sounds SICK!
as fun as these are, i feel like i need to learn something new....

good for you. have you ever heard of lunetta synths? i think you'll find them pretty interesting. go here, read this...

i think i like making simple 555 based synths better. i followed the logic of the pins, after reading data sheet...and made on on a breadboard.i like the sound of the sweep!
there are so many possibilities. i have been messing with different resistance values, pots etc. though i have too much to learn, i feel much more intuitive about making these now!
on the link...it was blank. ? is this basically a simple synth using photo resistors? i have ONE photo resistor, which i have been playing with...i am dying to make a hands free "theramin" like synth with these! ;-)

that link works fine for me.
Lunetta is the generic name for a vast kind of open source synth using CMOS logic IC's to create modules.
As is says on that link:
-Some people see it as the next step after circuit bending.
-Some people call it the next step after building the Atari Punk Console
-Some people see them as crazy gate sequencers
-Some people use the digital data and convert it to analog to run VCOs. (Voltage controlled oscilaltors)
-I call it the first step into DIY synth addiction.

you know. i have been trying to make sense out of the pins on schmitt triggers, and for some reason, i cannot find anything i can understand.
my method (so far, self taught) has been:
i started with an atari punk, then designing like crazy based on 556 timers.
lately, i have been designing around 555 timers, which i like. the way i learned how to use a 555 timer, was NOT copying a schematic, or wiring a circuit using a photo i found onling. but, i read the data on 556 timers, and read the data on 555s, and followed the logic of the pins (voltage in, output, etc).
what i am struggling with on schmitt triggers is that the pins do not resemble that of a 555 or 556. (i know, i need some physics, etc).

were abouts did you add the diode ! james

between pins 11 & 12 on the 556. the stripe tward 11.
