Title: PedalPCB Mini Heterodyne Receiver (EQD Data Corrupter)
Post by: Bio77 on January 20, 2020, 01:43:02 PM
Wanted to take a stab at SMD and chose this.  The build went really smooth, I'm excited to do some more SMD.  I bought the faceplate at PPCB, which looks super pro.  Was wondering if anyone knows of a good DIY way to make these?

Pedal is a really loud, noisy, and crazy, but that's intentional.  I think I might add a master volume, it's kind of tricky to get the three levels set.  Overall, really pleased with this one.

Looks great, just finished up one myself.(https://uploads.tapatalk-cdn.com/20200120/adb6de1f192044255164b99d3392e9f3.jpg)

Looking great! Nice work with the surface mount too!

I've never seen those faceplates in person, but I've laser etched acrylic (White top, black middle—sorta like a pick guard with the layered edge look) to get black lettering on white. The top/substrate colors can be whatever to get the effect you're looking for.

Wish there was a place to get those faceplates made. Could turn out to be a lucrative business in the diy community.

Ultra clean build.

That is slick looking! I didn't know this project even existed.

I've also seen folks use black FR4 and etching designs into it. It could be possible if you get some pretty thin stuff, and it will have a copper look rather than white. You'd have to get pretty good at etching, which I I am not.

Looks great! I love this pedal even though i have found absolutely no practical use for it but it keeps me busy for hours on end.

BuGG has to get them made somewhere. I'm sure he'd tell you what his method is if you ask. Ponoko is a place to get custom acrylic laser etches if you don't have access to a machine / maker space deal for that method I mentioned above. It can be rather expensive there, but you can save money by combining a bunch of faceplates on a single board order. They do offer a new user incentive too.

Nice work!
Glad it went smoothly for you- I had the same thought and built this mainly to try out SMD soldering with a cool effect as a bonus, but my results weren't so positive:

Anyhow, good-looking build, I'm very jealous!

Those look fantastic. I've built a couple of and projects myself.  I'm curious about the sound. How about An audio demo?

That looks cool, did you do the faceplate?

Yes, that sounds perfect!   Have you ever posted a build report with this technique?  I'd like to check that out.

Agreed, I didn't realize from the demos (or maybe it's just mine), that it doesn't do quiet, makes it less likely to work in a band situation.  Maybe a limiter in front would help.

I've seen these, they do look nice, but etching seems painful.

That's funny! I don't know about a de-bug of this one, I'd probably let it sit for awhile too.

Yes indeed I used the faceplate. It love the look!(https://uploads.tapatalk-cdn.com/20200121/b9d94b131b49e218c9bc553c5e6c5fe8.jpg)

Nice work. Did you solder the SMD ICs yourself? Good job if so :)

Odd to see a mix of through-hole passives and SMD actives.

What exactly does this pedal do?

The faceplate is classy but I think the real show is going on inside. Those are some pro level guts my friend. SMD and through hole are as perfect as it gets.

Could not agree more.  You did a fantastic job with the smd soldering!

It's an octave/synth noise maker, EQD Data Corupter.  There's a few demos if you google it.

I haven't yet (or any build reports, really). My WIP Man O' War DX has a box waiting with an acrylic faceplate. When I get that guy up and running I'll post the final build.

Yeah I'd love to see it when you're done.

I like your version better, it has the volume pot.  I plan to add a volume pot to the side of mine.  It's kind of hard to use without one.
