As a person who spent a lot of years doing DIY in Electronics.....

My experience... Only do this for love of it..... not to "save money"

That is the greatest mistake people make.... thinking DIY somehow is "cheaper"

I know I spent more money overall due to my DIY fascination...

But benefits include acquiring skills (like soldering) and developing patience

What other value it has, I don't know .... but other readers experiences may differ.... so post away

I personally am a fan of the MOTM 5U format. But then, that's because I draw my own panels, and get them made at FPE locally. (Also, I've owned a lot of Synthesis Technology and Modcan B, so I already had a bias there.) Really can't go wrong with either, though, and really... The REAL answer is to use both. Just use multiple enclosures, and separate by format. :party:

I prefer the MOTM format too. My synth is mostly Oakley for the basic functions (VCOs/VCAs/Mixers/EGs/etc) with a few oddballs for good measure (Neural Agonizer, SN Voice and a few others).

I built them all behind bride chamber panels and had a good electronics supplier in my town that had very cheap prices on meat and potatoes components (resistors/caps/etc) so they were comparatively cheap to build.

Unfortunately Bridechamber is no more, but he has sold all of his stock to Synthcube and a lot of the panels are starting to show up there. Synthcube has also stated that they are planning to continue stocking Oakley panels. Hopefully they will, although they'll need to get some support for that.

If you want to build a MOTM system I think there is more than enough circuits available to get some top tier synth voices going. You can only build so fast anyways. There are lots of interesting concepts in Euro world, but a lot of the new stuff is really digital/dsp programming based, and not really appropriate for DIY building. Although DIY euro seems to be getting more popular. Most of the euro circuits mount the panel components to a circuit board now though, which probably makes construction easier (or even possible in the small fiddly euro format) but it also locks you into pre fab panel design.

Initially, I agree that DIY is NOT an economical way to build a few modules. Yet after a few years of building inventory in my workshop I can easily build almost anything with components I have on hand with a minimal outlay for the odd-ball components called for on a design. I usually buy more than what I need for a project unless it is a very odd part. The panel is still the most costly part even in 5U (MOTM).

There have been times when a build only cost the panel and few bucks for what I didn't already have in the bins. Once you build a few modules you will see the repetition of certain components and know which to buy in bulk. Some hardware items such as the Cosmo knobs are always going to be pricey and available as the various vendors get supplied. I have only bought these from the manufacturer once and still have a few. I even keep a few oversized and undersized just in case I make my own panel design.

Recently I have had to part out a few modules for financial reasons. The ones that are off the table are the ones I spent my blood, sweat & tears building. I just can't let them go. They are worth more than I could ever recoup emotionally.

Organizing for component stockpiling

While offline, I am putting together a MOTM+Oakley BOM in Excel.
This is specifically designed to show me those repeating components,
and to let me preview what would be the total stock if I ever built the full MOTM and Oakley lines :-)

The spreadsheet has two simple and important features:
Information is entered per row/record exactly like a database, and each component row starts with the specific module designator it
was supposed to populate.
Second, component types are separated to tabs, so there would be one for resistors, a tab for IC's etc.
This makes it really easy to filter per module, or component, count totals and so on.

This comes from several years of stocking in the heavy lift Multirotor zone, of which I have a lab full of parts going on sale.

As for planning ahead for knobs and 1/4" jacks, that is darn simple:
I just open a few pics of the dotcom studio 88 or setups such as posted by sduck on the previous page - count all the jacks and knobs,
average them out and add a safety factor, as DIY modules tend to have more versatility built in - Mods, more CV control and knobs!

Here is a links to stock-piling BoMs, might be useful:

Component Stockpiling link #1
viewtopic.php?t=35341&highlight=

Component Stockpiling link #2
viewtopic.php?t=99082&highlight=

And don't forget to update inventories after each build!

UPDATE

Post by GiliRose » Fri Jan 22, 2016 3:33 pm

OK, take notice that I try and update the first post
with the coolest and best of DIY for 5U / MU I come across.

The latest add is Chrutil's 32 step (!!!) Arduino based sequencer.
This thing is a monster and has massive parallel power!

Surely Happy Nerding belongs under your ready made category.

All three available in MU are likely my next batch module purchase.

Please also check out curetronic for ready made and some DIY (maybe just PCBs now… I think they used to have kits).

Thanks for compiling!

Great list!

Two french sites focusing on dotcom. Google translate is helpful.

http://www.ozoe.fr
http://synthr.yusynth.net/?lng=en

The 960 clone from synthr is on my build list as soon as I can get hold of someone etching me double sided boards.

The Quantix-8 module CV Quantizer / Wavetable Oscillator from PaPareille looks very interesting.... Anyone have experience building it?

Per the website:
The Quantix-8 is a very polyvalent 7 in 1 module
  • CV-Quantizer
    Wavetable Oscillator
    Sample player LoFi 8bits
    CV-Sequencer
    MIDI to CV/GATE interface
    128 Harmonics Additive Synthesis
    Fast Zero Crossing detector

The Quantix-8 is controled by any combination of
  • CV or analog modulations (lfo, vco, etc ...)
    Gates/ pulsed clocks assigned to internal counters with multiples reset systems...
    MIDI messages of all kinds : notes, controllers, midi clock, sysex ...

@marfoski - Thanks, Links added!
Wish I could read the french on Neo Retro, and indeed -
The Quantix-8 looks and sounds like a handful!
