Zynthian mini

Sorry to trouble you again,
the case bottom 16 mm STL has some sort of half cutout inside. What is that intended for?
The 18.5 mm one does not have this. I am not a Freecad expert so I am struggling to get rid of this.
Also how many spacers should be used on the 40 pin adapter? The one with 3 spacers measures as 16mm, so I guess this is the correct one. I have the 2 spacer one as well but that is lower.

18.5 mm case is for rpi attached with 18.5mm post to pcb. 16mm case is for rpi attached with 16mm post to pcb.

Space between rpi and pcb (post height) can be calculated easily knowing that Female header is 8.5mm high, Every spacer is 2.5mm and finally rpi male pin header has also one spacer of 2.5mm.

Therefore:

female connector with 2 spacers will need 16mm post because the space between rpi and PCB is 8.5+2.5+2.5+2.5=16mm

female connector with 3 spacers will need 18.5mm post because the space between rpi and PCB is 8.5+2.5+2.5+2.5+2.5=18.5mm

It is hard to find 18.5 post but you can use 16 mm posts with additional screw nut.

I will check what is wrong there.

Congratulations to you! Iā€™m happy to see the MINI has been equipped with a new ADC/DAC boards. I look forward to your future advancements.

Hi Stojos
turns out the standard Freecad version of debian 0.20 was way too low to handle this file. I used version 1.0 on an old windows pc. It took forever and a day to load but it worked. There was something like a Hifiberry cutout inside which I removed. I am printing the files right now but my printer is old so it will take till tomorrow.

Terrific, kudos! :star2:

I use ondsel instead of freecad. It is almost latest and definitely most stable build of freecad. Try it. It is also free and you do not need to use additional pay services that they offer.

Any functionally rich CAD software require decent hardware to run. I have replaced recently my 8 year old dell xps laptop with MacBook Pro m3 and now everything in ondsel is instant. Before, any rendering caused by sketch change would take 10-15sec which is annoying if you do a lot of work.

I know that people canā€™t afford latest and greatest hardware and definitely I donā€™t want to go into MS/Apple/Linux debate. I love them all and all shine at different use cases.

Maybe you already know

Iā€™ve never used their ā€œcustomized version but still close to the original oneā€ so I canā€™t really tell.
I have understand that they have tried to develop a kind of ā€œin the cloudā€ collaboration system and, apart from that, done also a lot of push in the Freecad upstream code base.
So, itā€™s really sad to see such OSS enthusiastic people taking risks and, finally, economically, failing down at the end.
And I do not know how long their OSS ā€œOndselā€ version will last in the next few month.

Well, it was a bit off topic

yep this is Debian stable, with mostly quiet old software versions, but the AppImage of Frecad v1.0 works well under Debian stable (on x86_64 at least, because I have not yet tried with aarch64)

for sure it depends on the hardware onto youā€™re running Freecad, but also it depends on the objects that are embedded in the Frecad file (consequently on the size oy the Freecad file).

Eg: Iā€™ve found a RBPi5b STL model elsewhere, which is something like 20 or 40Mo size. And another one, much simpler, who is around 1Mo or 2.

This is REALLY life changing. Because Iā€™m using Freecad mostly on an Atom Z processor hardware, who should be 10 years old now, with 4Gb of Ram. I just have to be patient while loading the file (even more patient when heavy STL files are embedded) but once itā€™s done, itā€™s mostly okay in regular use.

Happy Stojos :blush:

Oh no, I didnā€™t. Shame. So back to standard freecad.

The Ondsel improvements are supposedly being folded back into the mainline Freecad.

Hi
the print went ok. There seems to be an issue with the sd card door. The bit opposite the screw is too long, or the sd card inlet needs more cutout.



I am using debian testing and while I know it is a bit behind, I was shocked to see how far behind it actually is. The windows pc was a very old one but the only one I had. It got the job done in the end.
Is the soundcard stable enough for testing now? If so I am going to print the other enclosure you did recommend next.

I know this is off-topic, but not sure why you had problems with FreeCAD? I have 0.21.2 on my laptop and it works just great. Granted itā€™s a nice recent laptop (Framework 13, 7840U, 64GB RAM) but itā€™s certainly no monster machine. I installed using the Flatpak method to install that version because I happen to use FreeCAD all the time for work. I was able to happily modify the PCB-fascia model for 16mm standoffs and change the four holes in the side to a single hole for the stock audio out plus another small hole for the mini output.

In fact, hereā€™s my STL file of the modified caseā€¦ I made the audio jack hole a bit bigger too because I have a different jack than stock.

And hereā€™s the FreeCAD file for just that modified caseā€¦

Hi
with that ancient version I did not even to manage to change the different models inside the file.
Can you explain how you modified your version, because I was trying to do more or less the same thing. I wanted the bigger hole from the old layout inside the new adac version. I tried copy and paste and while it did appear in the model it did not make it to the stl.

MINI got his big brother today.

@jofemodo wiki need to be updated to remove statement that MINI is higher than v5 :wink:

Hasnt there been a stored jlcpcb Job whcih can be used for my own order? I thougt there had been a link to this soime time ago.

There is pcbway order link posted on this thread in May 2024.

Thanks, i ordered the mini PCB
