Is that the OWON PDS5022S scope your using there, and if so how are you finding it please? I'm just getting back into electronics after many years away from it and fancy an oscilloscope this time around, so would be grateful for your opinion on it as the PDS5022S would be one I'm considering?

Nice work. I like this aesthetic. Love the LED also. I am building similar devices using 4051s, 4040s and 40106s. What oscilloscope / visuals are you using there?
Thanks. The aesthetic is breadboard and wires salvaged from old ethernet cable! I've since done a proper PCB and I'll put up a video of that soon.
The LED circuit is interesting because it isn't buffered and it hangs off a control voltage line so it changes the sound of the Nibbler. The circuit is a bit of a balancing act to set up and tune but not hard to do.
I did consider the 4051, but I just wanted to use a vactrol. I originally used a 4040, but I wanted bidirectional control so I substituted in the 4516.
The oscilloscope is an OWON brand, model PDS6062T. It's cheap and doesn't really go to 60MHz but it's very useful for showing slow moving waveforms. Lower trace is the control voltage, upper trace is the audio output.
won't be posting any schematics until after the workshop in October, sorry.
There is a list of the chips used if you look at the full video description and this should provide a good starting point.
I derived this circuit from looking and listening to other people's electronic sound boxes. I'd recommend doing the same as it will lead to you making something unique that we can all learn from as well.
The guidebook for this workshop should be up on the Dorkbot Sydney website really soon. I don't maintain this website, so I can't give an exact estimate.

beautiful work - great noises and an interesting control.

Cool!
Are you getting the glide effect between notes from a lag processor? If not is it just how you have the vactrol hooked up?

Glide effect is an RC delay (low pass filter) between two op-amps.
Circuit goes:
oscillator -> Counter -> opamp -> RC -> opamp -> vactrol -> oscillator

Lol! I meant sound aesthetic! But, yeah, nice.

AWESOME! Really cool sounds :) Are there any schematics for pointers for building this bad boy?
