DIY Throughhole MI Braids - Modular in a Week

Hello and Happy to be back!!!! :D
Alright, lets kick things off with a big powerful module, the Mutable Instruments Braids!
I this video I show you where to find the material to make your own Braids module on quite a low budget and also quite easy. Just some throughhole components to solder in place, and an STM32 to program.
There are a lot of things to look out for, so if you plan to make this, make sure to make notes throughout the video... ;)
Get the PCB set with panel and both PCBs for 9$ at my Tindie store, or download the gerbers for free from link further down:

Get a STM32 Programmer here (the STM32F103C8T6 is the 64kb version and thus too small but SOMETIMES they are 128kb...):

STM32F013CBT8 (128kb version) on ebay... not that many to choose from :/

Really great to have you back mate. I was actually just last week checking if there has been anything YT just hasn't recommended. Anyway, great that you've conquered the struggles and live and kicking again.

[@SkullDraizer]

The 12 bit DAC has more old school grit. 😉

[@AndersWeijnitz]

Nice surprise in the feed!

[@battysynths2996]

Very inspiring. Really looking forwards to your next videos. The TH Braids has a spare unused DAC channel, so one resistor and some code change can increase the bit resolution by adding together two 12bit samples. The mod for this through-hole braids kit can be found in a source code repository "through hole braided dac".

[@Nezzrac]

Very great to have you back!!!

[@MattBaker1965]

Great to see you back man and a cool module to come back with.

[@Mattycaos]

Sooooo glad to have you back!!!

[@faramoftae]

So good to see you back. All the best

[@naganomits]

It's great to see you back! and awesome module. I'm gonna try make one

[@johnhardig9754]

Great job Kristian! made my day to find this video!

[@dominicdit]

woooooaaah great to have you back!! hope everything is going well!

[@egeciran1785]

Glad you're back!!

[@dtharmo]

Yeahhh that was already a good day, you just made it excellent. Very happy to see you, welcome back ! All the thanks should be for you, without your videos my journey would not have been so successful 😊 So, thank YOU

Thanks Harmo! It means a lot. :)

[@peternoya]

Great content, glad to see you again!! 😀

[@benjiaomodular]

Heyyy good to see you back, Kristian! 🙌🙌🙌

[@glidinghigh4836]

Welcome back, you were missed

[@moderndaymedicineman]

nice to see you again man!!

[@motif1974]

Woohoo welcome back!

[@rogrevs]

Welcome back!!!!!

[@MeeBilt]

Wohoo! 🥳 Welcome Back, great to see you again! 😊

I’ve been watching your videos in the downtime. Some really nice projects aswell. :)

[@MeeBilt]

@ Thanks 😊

[@FloydAtema]

welcome back!

[@cr0wland]

I had some success with boards with a GD32F103 chip. The pinout is different but I managed to adapt them to fit the pins on the PCB.

[@mariobv947]

The C8T6 (the real one, not a fake or a renamed brand) and the CBT6 both have the same silicon die. The only difference is the factory settings that identifies the C8T6 as 64kB and the CBT6 as 128kB. The reason of why the C8T6 costs much cheaper than the CBT6, is partly because ST would test the endurance of the half of the flash for those dies being sold as C8T6 (though, usually, the unofficial extra memory would be as good as the first 64kB), and another reason is for marketing and/or trade rules of supply & demand. The STM32F103C8T6 is not the only case for this. In fact, ST has just a few dies for the whole range of MCU families. For example, the K4T6 would have the same flash amount than the K6T6. The same for the F2P6 and F3P6. There is a testing firmware for detecting fake Stm32f103 ICs. One of the tests is checking for the presence of 128kB. If so, good chances are that the chip is original.

Wow! Thanks for a good in-depth explanation that does explain a lot. :)

[@mariobv947]

@ You're welcome. You can check by yourself by taking a look at the XML files in the cube-MX-db folder of a source code repository (search in google because KZbin deletes my comment if I write the site name 🤷🏻‍♂️). For example, both STM32F030C6T6 and STM32F031CxT6 have DIE444. Chances are that some of the official features of the F031 are still present in the F030. EDIT: There is a TXT file listing all dies for the STM32 families, and you can find it if you search for "Is STM32F030C8T6 a rebadged bigger brother?" search term (again, i can't reference the file bc KZbin would delete my comment)

[@alvarobyrne]

long time no noise! noice to listen! much noise!

[@rmanpojo8485]

Great to see you back. top video... Later a Plaits or Branches?

I don’t think I’ll do the plaits. Even though it seems wonderful and simpler to use than the braids. A branches type seems like an easy programming exercise so might do a “variant” :)

[@jenniferw8963]

Hope you are doing well in your new home! Welcome back! Always love your stuff. I'd make this if there was a version that had a 16 bit dac. I don't mind soldering a single SMD chip I imagine. Sounds decent though with 12 bit. What was the grand total on this TTH module?

Thanks, about my new home... I have a video about that... :D Anyways, I dont think it was that more expensive than the Beaks, way less than 100$ for shure, I would guess not more than 70$? Something l ike that... Its the pots and jacks that really make the cost go up... :)

[@Qwiv]

Where can we get the illustrated PDF? Been gone for a while.

[@mymodularjourney]

I don’t know how I missed this one.

I even tagged you. 🤪

[@mymodularjourney]

@ I've been very distracted. But better late than never I guess...

[@alebrenna441]

Thanks once again Kristian for sharing!! Question: do you happen to have a video explaining the process to order the pcbs?

I think I show that in some previous video but might be time to do that again…

[@alebrenna441]

@ That would be great! Will have a look at your previous videos nevertheless!

@@alebrenna441I think it was the one about the power distribution board.

[@tinfoilcat]

Välkommen tillbaka! :) Great too see you back at it, I hope that you are still having lots of fun doing it! The garage looks like the old one, did you actually move? :D

;) I have a whole video abou that aswell I’ll share someday. :)

[@the2d]

I built a DIY looper/sampler based on the isd1820 and put the schematics and PCB layout for free you should check it out!

[@alebrenna441]

Can you share a link my friend? :)

[@martinjames7847]

Did you get any more of the 8T6 you were talking about at around 14.45? And if so how did you get on? Are they all 128k?

I’ve tried a bunch of C8T6 and they all work so far. So even though it is a gamble I still think it is cheaper to buy a bunch and try instead of buying a CBT6…

[@martinjames7847]

@ Cool. I bought one anyway and we'll see how it goes.

[@synthmoments]

have anyone ever had some tune throble? It seems not more precise, every octave has different tune. What can be hte problem?

I think it might need some calibration. Check the braids manual for how to do that exactly. If that doesn’t work it could be something on the data lines between the stm32 and the DAC. At least that is the most common error people have had. Check my discord channel for the braids for some more ideas maybe. Hope you find it. Let me/us know how you fixed it.

[@synthmoments]

@ thank you. After this post a discovered that i could calibrate Braids (Cal from setting menu). I'm doing some check and now it's better

[@MrBobWareham]

I don't know if you can advise me, but I have Tinnitus and want to make a woosh sound at 5,500Hz do you know how I can make this sound please, thanks Bob in the UK

Do you mean a noise sound but narrowed down to 5500hz? If you only have one specific frequency you will get a tone. I am guessing the 5500hz is the tone of your tinnitus? So maybe you want a larger spectrum which then creates “colored” noise. Making a white noise (full spectrum) is very easy and there is a video on that. Also you can try out the “colored noise” which is filtered at different parts of the spectrum. Or you can make your own with a white noise and one or two filters. Using one high pass and one low pass filter you can hone in on the exact frequencies you want.

[@battysynths2996]

Have you looked at the SoX open source command? It creates tones, sweeps various filtered noise and can apply filters to create .wav files. Also useful to create or modify samples for Eurorack modules with microcontrollers.
