There are indeed services to create both panels and pcbs. For panels, providing you stick with MOTM, you can go with Front Panel Express. You provide them a template and specs and you get excellent quality products at a pretty good price.

PCBs will require more work as you will have to submit a design file to a service that will produce the board for you. These services, however, are generally for production runs so getting a single board made will be either very difficult or very expensive.

As for you mention of DIY to save money - forget it. DIY is not less expensive than purchasing modules outright. You will get a better ROI buy purchasing a PCB from Modular Addict, SynthCube or another vendor rather than paying a manufacturer to produce it for you.

In addition, parts are more expensive the fewer you buy. Manufacturers purchase parts in the hundreds and thousands to reduce the cost.

For example, one of the toggle switches on a module I build / sell costs me over $18. In order to reduce the price to a mere $15 I'd have to buy 100 of them. Since this switch is used in only one type of module out of the dozens I build it really isn't worth the $1500 outlay.

You also have to factor time in to your cost calculations. It can take several days to build a module even if you have a PCB, panel and all the parts handy. Having to produce your PCBs and panels adds another layer of your time that has to be added into the cost.

For the most part, DIYers tend to build out of love rather than to try to save money. This (I feel) is because the thrill of producing a product or even potentially improving on a product through mods is what they (we) seek.

You can accomplish great things by building your modules yourself. It's a lot of fun, if meticulously wiring tiny components is your idea of fun, but it's definitely not the way to save a lot of cash.

For cost savings for DIY.. it is really only there if you build a metric shit ton of modules.

I am building a 157U of MOTM and 6U/150HP of Euro.

For the MOTM, the estimated cost is going to be about $10,000, or $64/Module. That includes tools, and most PCBs for the Euro side of things as well.

From Synthcube, you can see the price of a full kit is almost the same as a completed module. Yu really only start to save when you build a shit load, and you buy parts in bulk.

Luckily for me, the time factor of building these things is not really an issue. I have access to many of the components I would ever want for next to nothing, so all I would need is the PCB/Pannel combo. As I mentioned earlier, I am just not comfortable doing the etchings. Regardless, $60-70 a module with some time soldering is much more appetizing to me than $100-300. I guess I'll have to skip on the completely DIY modules for now. :(

S o ....
I'ts been like two and half something years since my last post here - wow!
As they say, life got in the way and I had like a zillion other things to deal with besides modular.
So it's good to be back and find most of the old nicks and some new ones too!

For most of last year I was working closely with my friend Yoad Nevo on the relocation and new design of his London studio,
so that was good fun, lots of acoustic isolation and absorption stuff, smart routing etc.

And now I'm back and hey - I still got a load of PCBs and components waiting for that magic smoke!

I find that the key PLUS for DIY is the time factor -
take it easy, spend what you can when you can, and build as you go.
And if it actually works when you power up, well - all the better!

So it is like exchanging time for money and large chunks of $$$ for smaller ones - a cap here, a tempco there, some knobs etc. - rather than shelling out for a complete module.

For page 1, another one to do to the list is Non Linear Circuits out of Australia. Even though all of the designs are for the Eurorack crowd, most of them work for +/- 15v.

A bit of rain and "working" from home allowed me to clean the electronics room. Thank goodness.

And delve into the DIY Kit-Closet! Three Voice of Saturns built - now moving on to two MFOS 16step Sequencers. Hmm, wiring!

When Radio Shack collapsed I visited a few local stores buying as many parts as I could. Mad discounts of 90%. I was new to the world of DIY and was not an intelligent shopper, more like "I'll have that drawer of caps and resistors". But the price was good.

The dials on all three of the VoS's are from Radio Shack - and truth be told they are kinda cheap - they are not true round and have sharp edges. But these modules are simple, playful things - so I figured why not stick a skull guitar dial on one!

The next two, on the other hand, are more serious builds and I am trying to find a batch of the connectors used by dotcom and others. Anyone know where I can order these in bulk? Or even better, where to find them with 10 inch wires on the males?

Any advise would be great!

OMG, the wiring on that MFOS 16-step sequencer...

I'm going to build one of those soon. I wanted to do it a few years ago, but other things (and illness) got in the way. However, I'm going to design a Panel PCB, so mine will involve no panel wiring at all. I'm not sure whether I will plug the circuit boards into the panel PCB or connect them with wiring to pin connectors, but either way, the panel components will be soldered into a PCB and all the panel wiring will be traces on the PCB. I started laying out this PCB a few years ago -- not sure how far I got. However, based on the projects I've been doing lately, I don't expect the layout to require more than a day or two to complete, and probably a single day to build.

I'll also be doing my own layouts of the circuit boards. I've never bought a PCB in my life -- I'm certainly not going to start now!

Did somebody say tight nuts? :razz:

Been gearing up for a weekend of DIY as well. I have put my first FCUK waverunner through the paces and I am loving the BPM sync goodness! I have two more kits ready to go this weekend so I will have LFO duties covered!

One of the things I would like to do is "see" what the LFO shapes do with the distort knob. I don't have a scope, is there a plug in, or software that might handle a simple task such as this? Or should I just spring for a scope at some point, as I am sure it would cone in handy every so often!

I've used Hantek's 6022BE USB scope and now their DSO5102P. Both are excellent solutions. The USB version is much less expensive but there's something wonderful about just being able to grab the scope, sit it next to your rig and see what's happening without all the futzing around that always accompanies a computer / hardware / software solution.

And the best nuts are the tight ones! :sb:

Awww c'mon......some of us have the futzing around with a computer down pretty good! All of my futzing around with analog shit gets "realized" in the ultimate form in my DAW!

Will check out your scope recommendations!

The 6022 looks like the solution for me! I have an old laptop that would easily pair with it, so somewhat portable! I like the option of the bigger screen....for those of us with poor eyesight and huge cocks. Speaking of which.....I need to go feed my roosters!


There ya go Faust.....you were waiting for it!!!!!! :mrgreen:

Ah these young folks who've never had to map an IRQ or memory address or worse yet.... deal with drivers that didn't allow you to adjust these things.

I think BBPP (Born Before Plug n Play) should be a sub-title in Computer Guy nomenclature to identify the REAL technical hardcore dudes :sstorm:

Of course those guys would be laughed at by older Computer Guys with the sub-title IPFA (I Programmed FORTRAN asshole :hihi: )

But seriously folks..... good choice. The software is Windows only (but it will also run under Parallels on a Mac). The device requires 2 USB ports and comes with a funky Y-USB cable. It handles 2 channels and I honestly can't say I've ever had a problem with mine.

and finally..... who didn't think GEM would be the dominant graphical operating system... discuss :slapfight:

I fought with the first windows box I ever built for weeks trying to get a sound card and MIDI device to play nicely with the OS. The next step was getting Cubase to play nicely with both as well! Thankfully most shit is pretty plug and play nowadays. I very rarely delve into the bios unless I am trying to do some "hot rodding"!

Ordered a 6022! Thanks for the recommendation!

Yes, because the damm output amp let its magic smoke out, so now you had to restart from scratch and gfl getting Sound Blaster to honor a warranty...

So I wander in here, hoping to find some crazy new 5U project - and instead find out that soundblasters are still a thing. I mean I guess learning something new is great and alll that, but... soundblaster? Wasn't that a 90's thing?

Those aren't molex. They're AMP/Tyco MTA100 IDC connectors and headers. Pretty much everyone carries them. The white bodies are made for #24 wires and red for #22. Other colors for other gauges. Don't mix these with wires not the correct size.

George Mattson sells the F MTA100 conns with leads already attached. Not sure if they're 10" or not, but Geroge is a helpful friendly guy. I'd get in touch with him and see what he can do for you.

Seems like Synthcube might also benefit offering this? Don't know if they already do.
