--- Quote from: UK on November 16, 2023, 08:20:36 pm ---Thanks to @sergk for the measurements of the DHO900's LA slot... can say with confidence that it's absolutely the same as on MSO5000.
Almost finished the shell for the mini-HDMI board, but the PCB will definitely require some edits for adding several slots and holes for the screws.
@oliv3r, did you already order the PCBs?

I did not, I've been simmering on a different board, so that I can review it with fresh eyes, and new insights :) So what changes are you thinking of?
--- Quote from: UK on November 16, 2023, 08:20:36 pm ---Really hope oliv3r will publish the final version of its board soon and I won’t have to recreate it from scratch. :-\

Yeah, I got distracted a bit; I will certainly publish everything, nothing to be recreated.
I see you added 3 screws, I wonder if there's room for them, and _need_.
Though those 3D renders, so sexy!! :D
--- Quote from: UK on November 16, 2023, 08:20:36 pm ---@oliv3r pls, check the board outline in the attachment. PCB requires small edits.

So, this raises a few questions. Do we really need 5 screws? can we do with just one in the 3 (1 in the middle)? They all go through traces :p and in the middle, it's not an issue, I can change the trace, but the outer two traces go between some caps/resistors, rerouting that is a little trickier. I've added a 2.2mm hole (smallest kicad footprint is 2.1 but want to leave room fro the threads?) and it looks like this. Might prefer to get the trace slightly further away from the shield hole though ... shouldn't be an issue?
Also, do we need to cut away so much from the connector side? I don't mind doing it, but the connector itself is much wider then the PCB (see attachment)

First of all, I have requested to split off the forum 2 times, but nothing has happened. Others mentioned this as well. If you manage to pull this off, it is much appreciated.
Secondly, The topic is about a low-cost alternative. This is a low-cost alternative. It's just not in easyeda, but that's not a froum crime is it? One of the LAPOD's follows the exact same principle as the original ...
So we are respecting the original thread, we are improving on the original design and adding more LAPOD's :)
But again, instead of complaining and derailing the thread about not- LA's, get the forum split. Please. We tried.
Btw

what do you think pod_sn65lvds is? :)
edit: Did the changes already, was easy and doesn't look too bad. Just need to discuss the extra 2 holes :p nvm, got the holes in, not sure about the clearance, but DRC is not complaining ...
oliv3r:
Great news everyone!
It's been 6 long long weeks, and it's not all there yet, BUT! I've finally gotten my CI/CD pipeline where I want it to be :) Had to get a few bugs fixed, features added etc to KiBot (Thanks Salvadore!!) but the results are pretty cool.
The repistory is right here, https://gitlab.com/riglol/lapod but only the breakout boards for now. I'm still wrapping up the pods (getting the LCSC part numbers in etc, getting rid of the ERC and DRC errors (or ignoring them where needed). The first pod is nearly done, so I'll hopefully push that tomorrow.
The MR where I'm doing my work is right here https://gitlab.com/riglol/lapod/-/merge_requests/1 and the pipeline has all the outputs https://gitlab.com/riglol/lapod/-/jobs/6004605746/artifacts/browse, such as this nicely blender rendered mugshot! (Should have used that as name instead of `front` ... :p).
There's also a ton of other files there, such as step files, vrml files and what not.
The connector is a bit crooked, that's a bug in blender that'll get fixed in the next big release in march, so until then, that's what it is. Also, I hope that we get a better lightening engine with kibot's blender run soon! There's also the kicad generated render, which looks a little better in some other ways.
Be aware, that the job artifacts expire in a week, which is good, as this is all a little WIP. Once I merge and tag the MR, the artifacts should stay forever of course.
The kicad files are also included as expected :) it is open source after all.
So ... in case you didn't miss me, I did think of ya'll :) Now if we could only get Dave to split the thread ...
S. Petrukhin:
Comrades ebastler and oliv3r, you have filled half the pages of the topic with personal communication with not very related topics. Got carried away. :)
This is usually called a flood in forums. :-//
I do not know how to highlight your communication and move it to a separate topic, is there such a forum opportunity.
It is possible that a moderator will do this, but not necessarily.
So don't go on, please. Create a new separate topic and put a link to it here so that those interested do not lose the thread of your discussion.

You might have noticed that
* all our discussion was about a low-cost probe for the MSO5000 (and DHO900), so fully on-topic, and
* oliv3r has asked the admins multiple times to split the discussion about his particular implementation out into a separate thread.So I can't understand what problem you have with oliv3r and me. And I don't accept your attempts to police us.
ebastler:
I don't think there is such a thing as a "thread owner".
It's fine with me to have the discussion about oliv3r's design split out into a separate thread; as mentioned, oliv3r has asked for it several times. But starting a fresh thread and losing all the history is not desirable. And I strongly object to the way S. Petrukhin framed his request -- describing this as a personal off-topic discussion by two people, which is wrong on multiple levels.
Anyway, I'm out of here since I will not get a Rigol scope which supports this probe. Nevertheless, I hope oliv3r's design gets finalized, since it is better as well as lower cost than the original Rigol probe.
