appologies for the necro-bump. I've been having trouble with this build I've partially breadboarded. I'm doing v1.1. http://www.geocities.com/thetonegod/payback_v11/payback_v11.html
I haven't done any of the opamp buffer parts. for now, I'm just doing the recording and looping logic. started with the recorder, and by grounding pin 2, I succeeded in making it record a short clip, and grounding pin 2 to play it back! with that part of the circuit working, I put it aside and did the 4093 logic. unfortunatelly when I hooked it up, it doesn't work anymore. the record led blinks rapidly for half a second (shorter duration and more rapidly than normal record blinkage) and the led around the 14093 stays on at all times when I have power hooked on.
I couldn't find a place in town that had 4093's so I got 14093's instead, which as far as I can tell are the same thing. is this a problem? you should consider me a total noob at logic switching with these types of components.
I noticed the tone god's post about mislabeled pinshttp://www.diystompboxes.com/smfforum/index.php?topic=65575.0
but I'm really confused.
I've found datasheets for both the 4093 and 14093 and neither of them are the same pinouts, and as far as I can tell neither of them would "support" tone god's advice to switch pins 8 and 10, and 4 and 6. if I did either of these, it seems like the layout diagram would change "logic" in the v1.1 circuit.http://ece-www.colorado.edu/~ecen4618/cd4093b.gifhttp://pdf1.alldatasheet.com/datasheet-pdf/view/11974/ONSEMI/MC14093.html
what should I assume to be true? the pin number swap, or the little pictures representing each of the four triggers, regardless of the pinout?
