Incredible smd work. It looks like it's come off an automated production line instead of diy!

I still don't understand the problem with the LM13700, it's what i've been using in all my stuff that was asking for LM13600 with no problem, like i told you before.

Anyway, very nice build as usual but this one is particularly badass!

Mark, this is crazy. In a good way. Really badass good.  I sense an impending run of these...!   

More solder paste? 

I think the issue with the 13600 vs 13700 might come down to tighter tolerances on smd parts (less stack up).  Not sayin you got lucky Rej, but there's been one or two old circuits I've converted to smd that didn't play as nice with specified pots and I needed slightly different pot values.

Another explanation might be a wrong part somewhere in the hundred or so passives. But I can't imagine something like that actually happening. 

By the way, the graphics and LEDs look fantastic too!

This is so incredibly pro! I'm stunned!

Just incredibly good.

Work of art.  Really.

i want to kiss this on the lips.

Thanks again, guys.  I fiddled with the Mix control and got it working a little better.  It won't go completely dry so I've decided to call it an Intensity control.  So now it works OK.

Now I could just get those darn 13600's.

...how?....seriously, your smd work is pure precision.

More awesomeness right there!

[Cortexturizer]

Damn. Some sick things going on here. Definitely sell this to some company and reap the percentages of sales

Great built mate.
Totally pro...

cheers.

Stellar work!

Just wanted to "pop the hood" (bonnet for you UK blokes  ) to see that fantastic SMD layout again.  Truly inspirational, makes me want to do more SMD layouts/population now.  So clean.  The symmetry of the layout is so eye-pleasing.    

Just a couple dumb questions...this is mostly 0603 right?  Also..the "L" pads at the bottom of the PCB...are those for an inductor/LED/wiring?

Yeah, the LEDs - That's something I noticed. It's not easy to get the switch & leds coordinated and laid out perfectly like that. A brain teaser for sure.
