Opamp via 9-pin serial cable?
« on: August 24, 2005, 07:19:48 PM »
I'm a big fan of Joe's discrete opamp and have had a few unsuccessful attempts at fitting "daughterboard" type versions of it into commercial pedals.  This got me to thinking about whether it would be possible to wire the pedal's opamp pads to a D9 serial cable socket, and then have the discrete opamp housed in it's own enclosure externally.

However, would the length of cable add noise or sully the signal in any way?

A 15 pin printer cable would allow you to mount switches for diodes or various pots away from the actual pedal too, allowing you to do much more than space would typically allow inside the original enclosure.

okay, I guess no one is into this idea.

I think it might work if the cables were shielded. I haven't opened a 9 pin din. It might be kind of cool to have it so you can plug in different versions.

Interesting idea for sure.

It'd be cool if someone made SMT versions of them.
I had the idea, but I can't solder that small.

The board would ofcourse be bigger then the chip, but still relatively small :)

Yeah, then encase in epoxy and then you get the latest version of the "ice cube"!
