DuoVibe #2
« on: October 23, 2013, 09:31:21 PM »
I liked the first one so much, I thought I'd build a smaller one.  :D

This one has a switch in place of the previous Waveshape pot. So it's down to two pots, two switches. Overall footprint is a LOT smaller as well.

I've populated four boards for this circuit on two different PCBs and they all sound damn-near identical, regardless of LED type or LDR type. I've got A100K in there now for Speed, but it's too bunched up. I think C100K would be a lot better, but still it's quite usable.

If you want a board, they will be offered as part of the almost-totally-ready fundraiser sale for Function f(x). Should just be another week or so. Look for an announcement here on the forum.

I went with yet another alcohol ink look, and added some metal corners to give it a Victorian sort of steampunk-ish look. I also glued on some metal decorative gears to cover the glory holes. She's a mess inside, as I did some pretty heinous mis-drilling.

I like the steampunk vibe.  Where did you get that LED bezel from?

Awesome. Now I'm looking forward to the Function F(x) launch even more...

Lovely build! :)
I'll hear the demow as soon as I can.. And a vibe is always welcome, so I'll keep an eye on this..

Sounds great!
Is that the final PCB layout?
Do you know if it will run on 12-18V?

The final has a few very minor layout adjustments, but it's 99.9% the same. So basically, yes.

I think it would be fine at 12v, but many op amps can fry at 18V. But more to the point, there's not really an advantage to running at a higher voltage. There is already ample clean headroom at +9v (no clipping whatsoever, even banging away on humbuckers).
