DIY - 4ms - Spherical Wavetable Navigator ( SWN )

Post by schnitzelbub » Mon Jul 01, 2019 10:59 pm

This thread is about the Informations on how to build a SWN DIY.

Whilst researching about the modules resources and options on how to build it, I reached a point where it was not clear if okay by the license.
So I simply asked 4ms via eMail for permission.

I ended up with a confirmation by Dan Green from 4ms-company, that allows small sized PCBA runs if absolutly nobody is making it for money / salaries / wages or profit. In his view on cc-by-nc-sa 4.0, this is absolutly not a problem. He also encouraged us to share this "knowledge".

Just never sell a DIY Unit or make money with it in any way.

4ms-SWN github:
https://github.com/4ms/SWN

User Files = BOM incl. MPN and Eagle Panel here:
https://drive.google.com/open?id=1oU4Eb ... ErXtoS4mdc

Actually the Panel includes a little modification on the RGB Push Buttons, because they are extremly rare and hard to source in small quantities.

In the end, I decided to go for one type, size and colour of RGB Push Button.

After 2 weeks of writing around the world, Mouser seems to offer one type of RGB Push Button as factory order with a multiply of 1 and a price of 3,32€ before tax.
From Todays view, this seems to be the best bet on easy sourcing this style of Footprint RGB Tact Switch.

This is absolutely awesome!!! Great work, and super cool on 4MS' part to let this all go on.

100% going to give this a try/add this to my ever growing backlog of DIY. Do you have any shots of your completed build?

It’s not built yet - it’s ongoing to sort out the hardware, parts and adapt the fw to fit the parts chosen..... :-)

But, yes, 4ms are absolutely awesome !!!

Ahhhh I see. Very exciting news either way! I'll be slapping one of these together the moment it is possible!

If a community PCB order scheme develops, I'm down for one board for sure! 4MS rocks.

Fully working (the photo doesnt do it justice at all)
What an awesome module!
Definitely not a module to diy to save money - only for the fun of it

wow props! amazing

having looked at the PCB i'm not sure if 'fun' is the first word that springs to mind

Looks very interesting. Are some pcb / panel sets available anywhere? Please.

It’s non-commercial (cc-by-nc-sa), so you need to do your own really or with friends. The pcb designs are on the 4ms github. The panel design is on the google drive linked above.... it’s pretty cheap to send off to eg jlcpcb etc

Nice work. Wondering what you ended up spending for this project?

well i went through our gb chat and actually got to 223,58e - so i think you are bit wrong or did not count some stocked parts

109 pcba
18,58 panel, lightpipes, aditional tax
18,89 thonk
50,74 buttons, rgb enc
26,37 mouser

223,58

hi i'm planing to build this beast, thanks for the infos and sharing thoses files..
I built the smr few weeks ago, it was a bit scary but it's ok, working like a charm.. The swn board seems to be another level! and the price of the rgb switch is scary too..

How many are actually on there?

The well buying button can be found for about U$3, and the Highly is usually around $4.50.

I actually buy stuff from Highly for my automation panels.

Would you have the reference of the RGB push buttons used in 4ms SWN ?

Thanks

Any builder sell it already mounted ?
Any bugs reported ?

A lot of PCB fabrication houses will also do the SMD soldering during the manufacturing process for you for an extra fee.

I'm an avid reader of http://www.batguitars.co.uk/ (you should be too!), and our man forestcaver has this to say:
Building the firmware was non-trivial. There was a trivial bug in the bootloader that required a one-line fix. Getting a build environment that built a fully functioning firmware was tricky (some environments built a firmware that did not function correctly). I used a mac in the end. After the bootloader I needed to build one firmware (changes to lines 32 and 34 in globals.h) to write the wavetables to flash. This resulted in a slow bootup (~20 seconds). So I flashed a second main firmware that did not include the wavetables (as they were now stored).

The pcba process was entertaining - there was a bit of guess work as to the correct parts to use - led encoders and rgb-switches. These required a large minimum order quantity.

The quality of the pcb was pretty poor - one guy had broken traces. I had a missing resistor (R80 - see above). The boards had a lot of flux left on them and some of the holes were almost completely closed and needed opening up.

After all this I have a lovely working module - and it's really awesome !
Hope you don't mind me jacking this from your website forestcaver!!


And also my eyesight just recovered from soldering the SMR.... I wish this thread didn't get bumped :hihi:

Do these PCBs have presoldered components? I have a couple Westlicht performer PCBs and a Teletype PCB... but no presoldered components. PM if you're interested.

Very impressed from this guy. A lot of good reading but there is no contact form ;)
Not sure Web forestcaver can make one completed to sell. I'm not equiped, dont have any tool, soldering skill ...

He's the best! Helped me more times than I can count, directly and indirectly.

..Although I don't think he or anyone would be producing them to sell, unless there are extra boards from the fab house sitting around. You can still snag these puppies at retail, and I suggest you do so if you're jonesin' for that SWN sound!
