Pedal Art Idea: FR4/Copper Clad Board

I wasn't sure which sub forum to post this to, so here it goes. Please let me know if there is a better place to post things like this in the future.

The Story:

I am trying to find my style when it comes to finishing pedals. Many of you are amazing artists and I love seeing what you share here. It is all very inspiring and drives me to find something that is unique and fits me.

I have a lot of single sided FR4 copper board, mainly from a custom wah project years ago (would love to share that here too) and the odd PCB etching job. It was very cheap and good to have on hand, but I rarely use it. So, for the longest time I've been thinking about using it for pedal art, especially after seeing how people make modular synth panels out of PCB's, and how PedalPCB and a few other pedal makers make the faceplates. Today, I finally gave it a go:

Overall I am happy with this result. I love the shine and can't wait to see how it changes over time. I don't know if I'll be pursuing this idea much further, as it looks awfully similar to the Fjord Fuzz pedals. However, I still want to try etched art like that and some more stamping with a board that covers the full length of the enclosure.

The Process:

The board is easy enough to cut by scoring it with a SHARP razor and a straight edge on both side and snapping it. Keyword SHARP: if the razor tip is dull, it will take much longer. It should snap with a little force. If the whole board is bending and not breaking, stop and score it some more. If you've made your own PCB before, you already know. I used files and sandpaper to shape the edges. This is a messy job and I highly suggest wearing a mask, gloves, and eye protection because the dust is nasty.

I sanded the copper surface a bit to clean it up, then stamped it with metal letter stamps. The copper takes the stamping well enough, but the fiber board itself is tough and resists it. I also tried to get some black pigment into the letters using sharpie, paint, and finally crayon, but I couldn't get anything to stay. I'm sure a bit more patience would've made something work. I finished it up with some more quick sanding up to higher grits, and finished it off with some car polish.

The End:

I found some pros to be:
it looks pretty cool, somewhere between the Fjord stuff and what Fairfield Circuitry does. It is a relatively quick process, took maybe an 1 1/2 to 2 hours. Copper clad board is inexpensive and some of you might have it lying around. Plus, it requires very little enclosure prep.

And for cons: It is messy and the dust is not good. That's about it I guess... unless you hate how it looks. Oh, and also the letters are impossibly impractical to see without any ink in them.

So where do I go from here? Well, I want to try some more stuff with the copper board, like etching and different sizes. I also want to try different faceplate methods, like designing one as a PCB and having it made. Beyond that, I really want to get into the UV printing stuff. I know it's far from unique at this point, but from what I've seen here, it looks really professional.

Let me know what you all think and please feel free to share if you've done something similar. I was going to share this with a build report of the Breakstreet, but I am still waiting for a few parts and figured this was enough of its own thing. Thanks for reading!
 
Holy shit, those look amazing! If that last one is liver of sulphur, then it's the darkest I've ever seen.

Would you mind going into more detail on the process for getting such a deep & consistent patina? I've used the salt + vinegar in a sandwich bag method, but it came out quite spotty. The aqueous ammonia & salt method has been on my list for a while, but I don't think I've ever seen a result as nice as that. Definitely looks like stars or the milky way.

Nice job on the simplicity & readability of your lettering, especially the integration of the LED into the text. Is that screenprinted on after sealing the copper patina?

That's liver of sulphur. Yep, it came out pretty dark. Sometimes I get jet black finish, sometimes brownish or black with a slight blueish shine.
Here's the one with dark brown look and dark copper. It's all about solution strength and bath duration.

I do not remember exact details about those particular faceplates. Plastic container, paper towel on the bottom. You need some kind of a support to keep the board couple mm above the towel. I wet the towel with the ammonia, sprinkle the board with salt, put a mist of vinegar.. you have to experiment. Try with ammonia and salt only, vinegar and salt only, mix of those.

No, it's an ordinary etch. I have a copper clad that has a white, paper based laminate.
 
These all look awesome. I attempted to use some copper but my results weren't nearly as good as the ones here. I really bonered it when cutting and got my edges all out of whack.

Anyways, I etched the negative space here (the lettering is raised) and I left the copper un-coated to just see how it aged naturally. I feel like it's got that "Danger, stay out of the mine shaft" kind of look to it, so I kind of dig it.

I have some more copper sheets remaining and have been wanting to experiment with it a bit more, so thanks for posting this, it's great inspiration to see the rad things you are all doing.

Is that just copper metal sheets? Like not PCB material? The etching looks pretty cool, adds a lot of depth too it.

I am planning to head to the local home improvement store and get some sheet metal. They sell thin aluminum sheets that are treated to look like brass or copper. I think they will take the letter stamps better.
 
Love this whole vibe so much. I've been meaning to do an engraved metal tag for enclosure art for a while now, it just looks so tight. If tayda's uv printing wasn't so cheap I probably would have played around with this sort of stuff by now lol and I always love seeing it for inspiration. I haven't figured out an enclosure for my mesa boogie triple rectifier board (forget what its called because there's also the dual rect board) and I really want to figure out a way to use diamond plate on the enclosure

Yeah, this is just 24 gauge copper sheeting for jewelry making that I bought online. I used an iron to transfer laserjet toner to do the lettering and then taped up the back and sides with packing tape and let it hang out in ferric chloride for a bit.
