Macro Oscillator in 5U (THT based on "Plaits")

Post by EOTS » Sun Apr 14, 2019 2:49 pm

MU version

Based on the Eurorack module "Plaits" invented by Émilie Gillet, licensed under the CC-by-SA-3.0:
https://mutable-instruments.net/modules ... en_source/

The first modules are now built and working:


It's a shame, but it seems I'm still under 100 posts, so not formally allowed to offer stuff here. Please PM or contact me over at Facebook https://www.facebook.com/profile.php?id=100008336080650

Seems I've to get much more chatty ;-) :nana:


DIY Panel / PCB sets are available.
Mostly THT, 4-layer PCB is containing the UI elements.

PCB either presoldered or not.
Panel is optional.

MU version:
BOM Macro Oscillator MU v2
Build Guide Macro Oscillator MU v2


MOTM version:
BOM Macro Oscillator MOTM v2
Build Guide Macro Oscillator MOTM v2

Simple Drum Demo

Little demo video available here:


My first attempt on a less sloppy video, so please bear with me.

:love: Beautiful looking build! :tu:

If you remove the letter "s" from the "https://" of the video URL the embedding will work:

It's interesting that someone else recently made a batch of 5U Plaits, mainly for his own use. He use mostly SMT. Details here:

Thanks John!

Kudos to yourself, I've always enjoyed watching and listening to your videos!

In case you're still into MOTM, there will be an second version, I hope it's ready for assembly & testing in a couple of weeks.

Good to know, thanks for the suggestion!

The layout is pristine!! Both modern and mindful of the 5U tradition. The full-size knobs and text labels for all synthesis models are a huge improvement.
And did you guys noticed the perfectly aligned hexagonal nuts?

Now the question remains, what will you port next? Tides or Stages perhaps?
Black Knobs are dead!

Interested! Any change for pcb only -option? I'd like to make custom panel. Thanks!

Thank you! :mrgreen:
That's balsam on my soul after half a year of work.
Like a good friend of mine used to say:
the human being is able to withstand an enormous amount of compliments
:hihi:

Those really look interesting!
Which would you like to see first?

Currently I'm planning to build a dual oscilloscope module.
From time to time, I really like to see what's going on, also visually.

PCB only option…

Yes, PCB (4-layer ENIG)

Word of caution: The STM32 QFP-48 chip is very hard to hand solder and it's very easy to lift/destroy pads and damage the PCB beyond repair.
Remembering my first attempts of I've destroyed a couple of PCBs myself until I bought a reflow soldering station.
Of course I don't know about anyone's soldering skills, but I just wanted to outline this as I didn't expect it myself to be this hard back then.

So if someone's new to tiny nasty SMT stuff and still want to go this route, I'd very much recommend practicing on Patrick's great EDU PCBs:
Patrick SMD EDU PCB
AFAIK he also offers kits.

It looks very nice! It's a shame the pcb is as wide as it is - it would be nice to be able to use it in MOTM format. (edit: missed the part about there being a smaller version soon!)

sduck, like I mentioned there will be a smaller version with a different PCB.
Also with MOTM style panels (3mm, powder coated, etc etc).

Here's an image of the prototypes in comparison:

I think Tides are a bit more universal (being both modulation and a sound source) and there's nothing quite like it in MU right now.
It looks like it would need 3U of space.

Thanks for letting me know! From a quick glance yesterday, of those two I've also preferred that one. But really I'll have to study those modules in detail.

MOTM

Post by EOTS » Mon Apr 15, 2019 6:27 pm

Like I said, MOTM is totally under construction,
but I can show you one of the built paper prototypes,
that's nowhere near final, fonts are complety differnt etc,
but just to give an impression.

I didn't even notice your low post count, too busy looking at your sexy panels! :eyes:

Come hang out in the 5U section, there is usually something interesting to chat about and it's one of the most friendly corners of the Muff Wiggler empire! 8-)

I am thinking about getting a PCB with the presoldered SMD ICs and then source the THT parts locally and make a panel for it but the more i look at it the less i am sure that i could drill a plexi panel accurate enough for this one.
