Hey all! Seems like it's been forever since I finished a build so I am way happy to get this one boxed. It's a ROG Mr. EQ (http://runoffgroove.com/mreq.html) that I did up a little layout for. I assembled and tested the board over a month ago and then forgot the orientation of the switches so those are all in upside down. But at least I f'd them all up in the same direction. And I just don't feel like tearing it apart to fix it. The LED is a little dim, too. I normally use clear LED's and 10K is my standard CLR value for those. I decided to use a diffused green one on this build and forgot to lower the value. But all-in-all I'm happy with the little guy.
Neat circuit without too dramatic boosts/cut. Another big thumbs up for the folks at runoffgroove.com

Mark- beautiful as always! I was wondering what you've been up to...
Chuck, you, PD, and wgc do scary-good SMD stuff!
Very nice, Mark.
Your SMT soldering has always been good, but your layouts are getting better. Your internal wiring is really nice, too.
whoah, sweet! i especially like how the silkscreen is so nicely labeled.

Thanks Billy. I've had a few other things consuming my time and money lately. Feels good to be back on the pedal horse.

Thanks Alan. Those dudes are doing some killer SMD stuff.

Thanks Dave. I'm finding the key for my layouts is having fun with them. I can't imagine doing them if they weren't fun. It would just be a lot of hard work. Your help and advice early on has been huge, too. If it weren't for you they would be cluttered with big, ugly electro caps ;)

Thanks. I have spent a lot of time tweaking all the component silkscreens. So much so that as much as I'd like to try some of the other PCB design software available, I just can't bring myself to do it all over again.
Thanks for the kind words you guys. If it wasn't for Mark and Dave, I'd still be clipping leads wishing there was a way to do smd. Not trying to convert anyone, but it's a good skill to have and you just might like it.
Great stuff and totally agree about making it fun. Diptrace was super quick to pick up, component editing is a little unclear sometimes but Brian's library and spark fun library has most of what I need.

What is this sorcery you speak of? No smd electros? ;D
But seriously... how do you properly substitute other caps of higher value? Tants?

SMT Tants > SMT Electros.
IMHO, of course.
Moar capacitance with smaller caps - I've been meaning to experiment with capacitance multipliers.

Yeah, I've hit this smd tant stumbling block back during the f(x) fundraiser. Without access to Mouser, tants are pretty much unobtanium to me. Whatever I could find on ebay was either ridiculously expensive, ridiculously large (D/X) or missing values.
On the other hand, smd electros are a dime a dozen and readily available anywhere, chinese make some nice value kits and all that at the expense of them being obscenely large and sometimes wildly out of spec.
Right now, unless someone can hook me up with some decently priced tants, I'm gonna ride the electro wagon and suck it up.
I don't think there are any tants at all on the ffx fundraiser board. There was an issue with the 47uF ceramic, but Brian included those with all overseas shipments.
Did you not get yours?
I really like this build. really well done inside and out. I should try some SMD again :)
You have to me some sort of magni-eyed, tiny-handed freak! :o
Impressive as always! ;D

Yeah, sorry, lapsus memoriae... it was that big ceramic and I did get mine (both in the package and that part groupbuy) but it's just more of the same, really. Parts that barely exist outside of Mouser world and that are highly inaccessible to me.
I'll look around ebay again but the situation couldn't have improved much...
Thanks guys. It looks like the electro question was answered but generally I use MLCC's from 1uf to 47uf. Above that I either use tants or sometimes I'll put a couple MLCC's in parallel. It does increase the cost considerably over electros but since they are one-off builds I can deal with a couple extra dollars in caps.

This basically sums up my exact approach as well.
