This is a Belton-based build that I've been meaning to do for a while. Jon (Midwayfair) and Mark's (Chuckbuick) builds finally inspired me to throw it together.
Basically, it's Forrest's Box of Hall circuit sized for a 1590A. I prefer using full-size enclosed jacks in 1590a builds, so that was the goal. I found that I could fit a Belton in there if I put it directly on the jack top, so I designed the PCB to have a cutout so it could do exactly that. In order to mount the brick as low as possible, I also had to put all of the components on the bottom of the PCB. It worked out fine. It's a tight fit, but not a particularly difficult build and the brick fits into the recess of the top cover without requiring modification. The most difficult part of the build was that I swapped the labels on the top cover, so I had to cross wires for the ripple (feedback) and tone pots.
The color in the first two pics is a bit off (too blue). The third shot is closer to the real color.

That is just amazing. Just goes to show how using those tiny surface mount components can open up all kinds of possibilities. I dig those ripples too!

Thanks a lot.
Yeah, SMT components do open up another world. This build would've required a completely different strategy with through-hole.
Your 1590A builds are usually exceptional, but this one is particularly outstanding. And I cannot believe how clean your SMT soldering is.
I may have asked the same question on another thread, but are the wires 24 or 26 awg?

The ribbon wires are 26. The single wires are 24.
Ohh man! You kill me with these SMD stuff. You know my love for them! ;) I just can't get the stuff I want, because I'm buying exclusively from Tayda. Someday, when I have enough money to buy from Mouser. It's very pricey with shipping to Greece. :-\
Great build again! I love the thinking you put into designing it. How the PCB has to be in order to sit on the jack! Just love it. It shows the level of workmanship! :)
Well done!
Hector

I see, thanks. I've used the same wire (26 awg spectra-strip) for my Lunar Module and a few other ongoing builds and found that the ribbon made the wire inconvenient and rigid (so now I separate the wires and twist/braid them). But I can see how you take advantage of this, given the way you box things (as seen here (http://www.madbeanpedals.com/forum/index.php?topic=8671.0)).
Dude... the outside looks so much like a little pond that's had some pebbles tossed in on a calm, still morning.
Then you look at the SMD work, and you're like...
Wow.
Great work Dave.
Jacob
wow....very very cool! How did you make the graphics?
dude. spare PCB's? that thing is der coolness.
I'm impressed:) ... Taking the compact thing to a new level!

Not that I am gonna rush for it myself, but when you do the smd soldering... how do you do? do you pre-tin? I guess you need some kind of tool to keep the component in place while you solder? Is there a videotutorial that is good?
Cheers!

Thanks Jacob, that is exactly what I was going for with the graphics.

The graphics were drawn in illustrator. It's just a series of circles. As they get further from center, the lines get thinner and the spacing between circles increases. I then etched them with a laser engraver.

Unfortunately, I already shipped out my two extra boards to Brian and Forrest. If there's a bit if interest, I'd probably order more as I wouldn't mind having a spare or two for myself.

I don't ever pre-tin the pads. I just apply flux to the pads, then Hold the component in place with tweezers. Then I add a bit of solder to the tip of my iron and touch it to the joint. Because of the flux, it flows right from the tip to the joint. If it needs touch-up, I add a bit more flux and touch it again (generally without adding more solder).
There are some great tutorials online. I'll try and dig one up.

Thanx:) ... But I actually think that you covered my question with your answer. Flux->tweezers->solder on tip. If it were me, I also had to add a magnifier ;).
Keep up the good work:)

I think most people would want a magnifier. Luckily, there are many inexpensive options out there.
There are also pricier options, like a microscope, which is my preference.
... I'm not sure I'm worthy to be on the same forum as you, PD. (Almost put down BBS, not forum...)
Oh shoot !!! man that's......that's ....I don't know !!
On ten I give a twelve !! Congrats !
Awesome! Put me down for a pcb if you order more
That's great and all, but, I dunno.. I just feel like you have the power to go smaller...think micro... :P
Got a sound clip this is badddddd
That etch is insane...that layout is insane...this whole build is insane! We're not worthy.
