Hello Everybody! hihi

I've been building modules for a few months in a variety of ways, some from kits, some from pre made boards, and some from boards I have etched myself. The ones I have been etching myself are all the "oldie but goodie" MFOS designs.

I was wondering if this fine community might be aware of some other sources for ready to etch circuit board layouts. Or, if anyone has any eagle files for boards they have designed that I might be able to etch. So far I have only done single sided boards, but I'm game for trying double sided too!

Also, if anyone is designing a module and wants to make a prototype with out shelling out for a run of boards, I'll gladly etch one for you as long as I can etch one for myself! 8_)

Yves have press and peel layout for all his modules over at, http://yusynth.net/Modular/index_en.html

The microlarge 808 clone has ready to etch voice boards: http://xlargex.xl.funpic.de/

I used to be all about etching boards myself but honestly, the effort involved and the availability of cheap proto services like BatchPCB where you are only paying a couple bucks per square inch for a double sided, silkscreened, professionally made board has really sort of soured the whole DIY etching for me. Sure there is the mad scientist cool factor but at the end of the day (and thats how long it usually takes), I'd rather just upload gerbers, pay $35 and have them deal with it

Check electro-music.com/forum
There are a bunch of buchla designs for etching.
Also some stuff here. http://www.simple-answer.com/DIY.html

Fonik has a nice 292c design ready for etching. I think he posted it at Muff's recently in the LPG thread.

Check out the AMORE system at http://hem.bredband.net/bersyn/ There are board layouts for all modules.

I'm a member at a hackerspace in Louisville, Ky, called LVL1. We have a laser cutter and have figured out how to skip the press and peel step using a spray paint mask and etching off the parts we dont want with the laser. It makes the process waaaayyyy quicker and less of a hassle. It also works really well for making acrylic front panels. 8_)

Reviving this thread to ask: Are there any more good resources for ready to etch circuit board layouts, other than the ones listed here already?
Kosalos
All my layouts use small boards (70x100mm).
All use wide traces, so etching the board is very forgiving.
I'd try the Polivoks VCF first. Small parts count, but great sound!

Next the Thomas Henry VCO 555.

https://www.muffwiggler.com/forum/viewtopic.php?p=2626459&highlight=#2 626459

Then the Wogglebug.

https://www.muffwiggler.com/forum/viewtopic.php?p=2608235&highlight=#2 608235

There's others, especially the Multiphase.

Do a search for author Kosalos to find all my Muffwiggler postings of layouts.

Thanks, those look like interesting projects

Some Moog Modular and Minimoog circuits available here:

http://neoretro.jimdo.com/diy-synthé/moog/moog-902-vca-diy/

Paste the address into google translate. (Does come up with some confusing bits though e.g. "Listening, the grain is gorgeous (the famous copper color)")

I have etched but not yet built up the Minimoog pre-amp. A pre-amp or distortion which can also apparently be built twice for a first class stereo mic pre-amp.

Note that for some of them you need -6v (use the add on circuit shown rather than 79L06 as it is more reliable and several circuits can be powered from one of these -6v add on's)

I think chimio means electrolytic btw
