Hi there
I made a crunchbox layout using SMD. There's a number of passives on the backside, kept the space a little less crowded.
I had an empty box that was drilled for four pots, so I stripped it and recoated.
I'm kind of wishing I had started with a new box and kept all but two of the knobs as internal trim pots. Would've made the wiring less bulky, and I'm going to rethink using the tayda ribbon for future stuff. (I will probably just toss what's left.) The amphenol stuff is much nicer, just wish that it came in other colors.
I know that a lot of people would probably like the ability to switch out various diode configurations, but whenever I've done that in the past, I pretty much just find my favorite one and leave it there.
So I used leds, I used oversized pads to allow swapping out for other diodes. It might be possible to do something asymmetric by stacking diodes, etc, but really I'm trying to simplify things towards what I regularly use.
Decent distortion circuit, so far it sounds cool. I might just build another with no knobs. Because simple.
Box is powdercoated by me, laser etched graphics backfilled with black acrylic paint. The text was maybe a little too detailed to etch as clearly as I'd like at this size, but still fun.

That's Mr. Diablo to you..!

Thanks for looking!
Wow, that's badassery right there.
Looks great, Billy!
Love it!!
That's beautiful!
Nice build man. Love the art!

Thanks guys!
Also the wires are a tad long for assembly. The pcb mounted switch sort of dictates a certain order.
Nice one! I dig the graphics layout
Slick build, Billy. Nice layout.
Thanks Mark, I've had some great layouts to aspire to..!
As abaove, great job on this! I like how you mounted the 3pdt to the switch. :o
how do you etch and paint??, i mean what do you do to stop the paint fills the etched areas???

He mentioned it was laser etched after it was painted and then back filled with black acrylic. You can get enclosures laser etched at your local trophy shop. The results are great. Some paint colors seem to work better than others as far as contrast goes. Back filling is a good solution in that case. Of course you need a steady hand for that! He did a great job on this!
Thanks for the kind words guys!
Stomp town hit the nail square on. A trophy shop would probably do a better job on the etch than I did. The contrast is a challenge.
Backfill not that hard actually. I just smear it on, let it get tacky, and wipe off the excess with a damp rag. The hard part is keeping the acrylic in larger etched areas, sometimes it wipes out too and you have to redo it. Some guys have had good luck with crayons and a little heat.
As with anything, a little trial and error, and patience helps a lot.
Whoa! Impressive layout and box!

i want a laser etching cnc jejejeje, amazing job but i want to hear it
someday I'll make some demos! :P I would like to do something nicer than voice/video recorder on my iphone
This one sounds pretty much like a standard crunch box, though. The leds might give it a slightly different flavor.
