Been browsing the schematics on Experimentalists Anonymous again (I'll just refer to it as EA from now on for speed of typing!) and found an ADSR Generator I think I can tackle. I got some CD4093 Quad Schmitt Triggers today and have decided to give it go and see if I can't hook it up to the square wave oscillator for some impressive sounding results.
In the meantime I found this site which describes an interesting little oscillator circuit that can be made with the 4093 chips. Obviously the end result is no good for my final project, but I'm learning here! lots of fun to play with anyway, crazy sounds galore! I suggest you have a go at building these circuits as it's good practice for putting things together on breadboard. The approach I took was to wire up the circuits based on the schematic and then if it didn't work check the breadboard picture to see where I went wrong. Usually I'd forgotten to wire up the power and/or ground connections to the chip, very frustrating!
I practiced putting the circuit together and taking it apart again until I could do it without looking at the site. I'm still not entirely sure how the chips actually makes the oscillations, but I'm trying to learn as much as I can here and I think a good approach is to try to learn the layouts of all the chips I'm using and how they behave when connected in various ways. I highly recommend printing out the datasheets/pinout diagrams for any chips you're using in your circuits and having them pinned up nearby for easy reference, as it saves a lot of time clicking about to get them up on-screen.
Now to tackle the ADSR generator...
