Since I etched the originals, I can etch these guys for people that want things etched. It may be a lot of shipping back and forth for folks that want it, but i can try to minimize what i charge to basically cost for this project.
Full disclaimer though: I have a bum knee that I just had surgery on a week ago and the wife just was in a car accident and broke her leg. I will be a little slow to get them done, but would be more than happy to help the doom brotherhood.
Ouch! Hope you both heal up quick!
I stumbled across an article on etching using salt water and electricity. I may give it a shot. sounds like not crazy difficult.
Have you ever used that method?
Regardless of my level of success at that I think most would want a box etched by you. Even if I manage to get it right I would not be prepared to do large batches.

I'd already have a stock of most if not all components needed so not too into a group buy on parts myself but I would add bitcheslovemyswitches.com to the supplier list for jacks/switches/cases/knobs.
If you do end up doing US how much would it cost?
I'm not 100% really as I haven't worked out cost but I'd guess about 100 dollars at most, excluding any etching of enclosures.

Thanks man. I'm doing alright, I have etched some things, I just had to rearrange my set up a bit. I am actually healing surprisingly quickly. My surgery was the 3rd, and the drs said they would be happy if i could bend my knee 90 degrees by this point, and I can get 120+ So i am on the mend. The wife is going to be a longer, slower recovery. I appreciate the sympathies.
I've not done the salt water etching, but i just read up on it. everything up to dipping it is identical to my process. (i use a pcb transfer paper to do mine... when i first started, i got way more detail to transfer with that paper.) transferring the mask is the longest step in the process.
Chemistry soapbox, feel free to skip if you don't care.Essentially, the salt water, FeCl2 and CuO/Cl etchant all do the exact same thing. You are oxidizing the surface of the material you are etching. Basically you need a proton from SOMEWHERE in acidic solutions you get it from the acid itself but you have: metal + H+ -> metal+ + H When the electron transfers from the metal to the hydrogen atom, you start to form H2 gases. The Metal+ ions will generally start to react with the anion in solution this wipes away.
Eveyone has their way. From reading the one article i read, the salt water etching technique takes WAY longer to etch than the rest (HOURS!). Once in solution, I am generally done with a single pedal in a few minutes. The real kicker is, the stuff i make and use, and the FeCl2 etchant that many folks use (and is usually what people buy when they buy etchant) is far more dangerous to handle than the salt water technique. to most people, chemistry is sort of voodoo, and the thought of a chemical burn doesn;t sound pleasant, so people shy away from the whole process. If that is your boat, try out the salt water version. It may be awesome!

Yeah the attractive thing about it to me is definitely the lack of toxic chemicals I would need to store. I dont mind if it takes a little longer, I'll experiment with it and will report back when I have some results.
Knee surgery is no fun. My knee did a spectacular job of shattering and I'm still limping around after 2 surgery's. Total replacement would be the next option.

Ooof! Mine was a "simple" meniscus tear. I can't imagine shattering a knee. Mine was all arthroscopic, done in about a half hour and the difference is night and day. I had less pain after the surgery then i did prior. I got lucky!

Spoken like a true former grad student, lol. I'm checking out the doom room to avoid doing chemistry right now...

If it's not too late (I've been busy and haven't checked the forums in a week), and if it's possible for Matt to ship to Ireland (I assume it would be if he's shipping to Moose), I'd like to order one PCB for myself. I'm going to have a go at putting it together myself. If I'm struggling I can send it up to Moose.

You can add the pcb to my lot if that's handier, be under a euro to post up to you then.
