Hey guys disregard the first layout I posted, it actually has a couple problems, and I am working on a much better one.

Here is the plan. I will be posting PDFs for a single side version(actually a few versions) and Brian and I will likely produce kits for a more optimized double side version(s).

Cheers!
Russ

A mute relay would be a nice addition if Russ decides to it, an easy addition if space allows. The board looks quite crowded as is so letís hear if this is possible.

A mute relay (optional when stuffing the PCB) will be on the new PCB. Stay tuned.

Russ,

I was looking at the pic board again. Naturally, I am IMpatiently awaiting the kit. Or at least the boards.

Anyway, I have a few requests that would make your boards more flexible for DIY use:

1. Can you wire all 18 outs to resistor/FET output Pads?
2. Can you add an ICSP header?
3. Can you make the unused portion of the board into vector board? Or better yet, Proto space with power & ground lines, and trace connected pads for easy circuit addtion?
4. How about a Crystal mounting spot?

Actually, I think making the spareboard into proto space would solve all issues. I could easily add anything I want! The possibilities are endless!

FYI, I have never done any PIC or PCB stuff, so my comments may be complete newbie drivel. Feel free to say "Objections Noted" and ignore me if I'm full of BS!

I just thought of another advantage of this set up. Because it uses a pot instead of an encoder, it can be retrofitted into almost any piece of gear with a pot. Just put it in line.....minimally invasive. Pretty cool!

Hmmm. That's a pretty good freakin' idea!

Wait, I meant, yeah, we thought of that...

Default Second prototype

Note IDC connectors and only six jumpers.

There are pads for all the available pins on the PIC and one each for GND and +5V.

It sounds great, with clean/smooth volume transitions.

The two PCbs are designed to be stacked, but I don't have the correct standoffs right now (on order). But even side by side they are smaller than a standard CD case.

Cheers!
Russ

...if you know how to make pie of course, with nice PIC sauce.
