Just finished building this guitar pedal. The enclosure is CNC'd from a solid piece of walnut, and the decorations are CNC engraved into 2mm copper. The orange and green are vitreous enamel, which is glass powder mixed with water and applied like paint, then fired in a kiln. Shoved a bunch of huge Vishay Dale RN60 mil spec resistors in there for good measure. Would love to see some other builds, or even other enamel work if anyone is doing that kind of thing.
>>2988671 This one is a delay - more specifically the circuit is the Seabed Delay from PedalPCB, which is a PT2399 based delay. Very nice sounding analog-style delay.
>>2988583 Gorgeous. The patina you'll get on the copper will be interesting.
I don't quite get the mil-spec resistor and cloth wire aesthetic but I'm not a guitarist either.
It's got me thinking for sure. For a one-off is it remotely economical to order out a CNC'ed enclosure these days? or is it really something you should already have invested in as a hobby?
>>2988681 I'm also curious about any future patina - I put a coating of Renaissance Wax on the copper pieces which I've had good results with on my copper/enamel jewelry pieces. Definitely seems to ward off fingerprints and the typical darker patina that shows up within a few months if the wax isn't on there.
I'm honestly not sure about getting someone else to CNC an enclosure, in my cursory searches I couldn't really find anyone who would do a one-off out of walnut. Maybe if you had a local shop and could provide the materials? Certainly might be cheaper than buying a CNC machine, but I will say that the Genmitsu has been an incredible value for the price
>>2989117 Oh yes that's my goal, got a lot of Art Nouveau references to work from. Kind of surprised no one has really done something similar, unless I just can't find it
>>2988583 as a guitarist I can assure you, you placed the knobs way too close to the foot switch. that thing is useless. pretty but useless. .. that'd the zeitgeist, tho.
>>2989254 Well, for what it's worth I've had it on my desk for a month and it's been great but I see the knob placement issue. Definitely more of an objet d'art than a gigging staple - or maybe just for people with tiny feet
>>2993502 I was considering that but didn't want to get into breaking apart the switches I have on hand - any recommendations? Maybe it's easier than I think? A matching switch would be sick
>>2988583 very nice OP What kind of kiln did you use for the enamel, and what was the kiln schedule like? Did it take a long time to cool down to prevent the enamel from cracking?
>>2994170 Thank you! I use a Prometheus PRO-1 for enameling - almost always running it at 1450 F, and I'm just popping the pieces in for around 1.5 to 2 minutes. This larger decorative plate may have been more like 2.5 minutes? I usually let the pieces cool on a rack for 5 to 10 minutes before placing them in pickling solution, that seems to be good enough to prevent cracking
