Title: The Gatekeeper
Post by: pickdropper on October 11, 2012, 12:45:29 PM
This is an ISP Decimator that I built with a board I got from jimmybjj.  Sorry for the lousy pics, it was somewhat overcast and they didn't turn out so well.  I may try again later.

Still dialing in the bias.  It's a gate, so there aren't too many superlatives to describe it.  But it will be useful at work with my Mesa Tremoverb.

I really LOVE this graphic! Nice knob too!

Amazing graphics! I really like your style. I'm gonna have to bid on your auction.

Crop circles!

Also: The pots, trim, and 4001 are the only through hole parts? Are you doing the toaster oven thing with these or actually soldering the tineh parts?

p.s. Now you just need a keymaster.

Those graphics are really cool. And where would one source a knob of that kind? John Lyons is the only guy I've seen use those before.

Yes, I hope there are more bids on the auction.  It's obviously for a very good cause.

This one is sort of a mix of SMT and thru-hole.  There are plenty of electrolytic thru-hole caps as well.  I've used a reflow oven for other SMT, but not for any of my pedal builds, yet.  This used 0805, so it really wasn't that bad.  I've hand soldered 0402 before, but I tend to lose too many of those while I'm working, so I usually stick to 0603 as a minimum.

And yes, it really needs the keymaster to work properly.  :-)

Actually, I got this knob from John Lyons.  You can find them on ebay if you look.  These are fairly cheap Chinese knobs.  The real Daven ones are nicer but very expensive (if you can even find them).

That's a super slick design. And anyone who solders SMT components is always impressive.

Looks great!  The knob looks like its off my grandma's dresser.  LOL

Everyone's said everything I'm thinking. Love it!
BTW, do you use a drill patter to fit all those jacks on the top?

Thanks for the kind words, everybody.

Um, I am not sure what a drill patter is.  Can you elaborate?

You know, I've done many top mount 125Bs, but this one was a bit tighter.  I shaved a bit of aluminum with a chisel to fit it better.  It fit before, but was too tight for comfort.  All good now.

oops, I meant drill patterN -- like taping down a piece of paper will drill marks to show you where to drill.
Title: Re: The Gatekeeper
Post by: pickdropper on October 11, 2012, 11:22:23 PM
Ah, I should've been able to figure that out.

Yes, I use a center punch to mark all the holes beforehand, but the center one is really the only important one as I drill them out on a mill with an X-Y table.   The drill spacing is all decided from the point of origin.

Thanks Rej, I appreciate that.

I'm a little late, but holy F**K!  :o
That's great, pickdropper! Awesome etching and unbelievable SMD action! What size are the resistors and caps? 0603 or 0805?
This is one of the most beautiful pedals I have seen lately! I think I'll agree with Rej! ;D
Well done!  ;)

Thanks Hector.  This board uses 0805 for both the resistors and caps.  On my layouts, I usually use 0603 resistors and 0805 caps.  I like having different sizes for each type.

Post by: Ettore_M on October 12, 2012, 09:29:02 PM
Sounds good! You gain even more space using smaller sizes.. I just started using SMD and I don't  think I can solder smaller than 0805. You should have seen my face when for the first time I saw them. I was like "How the heck am I going to solder these tiny things?"! For now, I don't want this to happen again.  :D

By the way, it would be great if you could make a tutorial showing how you solder SMD. I have to admit I'm not that good at soldering SMD, but at least they work.  ;D

The compnent arrangement really complements the graphic design.  That looks really well thought out.

Is there any significance to the straight lines coming from the control knob?  Such as minimum, maximum, and common settings.

Hey Hector, I remember seeing a really good tutorial a while back that somebody did.  It was nearly exactly the same as I solder SMT parts, so I'll try and find that.  If I can't find it, I can probably put something together.

The secret to soldering surface mount is iron tip size and flux.  A good flux pen can make things look a LOT better.  I recommend the Kester #186 Flux pen.  It's mildly activated RMA, so you may want to wash it after you are done.

Actually, the two lower left and lower right lines do correlate to min and max on the dial.  The upper one (that is aligned with the knob line in the photo) doesn't correlate to anything.  But once I finish biasing it, who knows?   ;D

Both sound good. But +1 for you doing a tutorial for the Members Projects and Tutorials subforum! I think more people would be interested in seeing something like it!  ;)

I know that flux makes things easier, but I've never tried it.. I always forget to buy some! My mistake, I guess... :-[
By the way, what tip size are you using?
Title: Re: The Gatekeeper
Post by: pickdropper on October 15, 2012, 06:32:49 PM
Hey Hector,

Sorry for the late reply.  For surface mount components I use a 0.2mm round tip.  The profile of it is very narrow as well.
