"Omni Throttle"/angled adapter

[mattcaron]

Your English is fine.

I was looking at this adapter, specifically: https://www.thingiverse.com/thing:5027171.

Looking at the connector, at the bottom of the GNX it doesn't look like what I consider to be a normal JST. When I think of a 3 pin JST, I think of this: https://www.chippernut.com/store/p20/3_Pin_JST_XH_Connector_(BWR).html#/. The one I have has this clip that you press to release, and I've never seen one like that before.

All the men are created equal, the angled adapters not Seriously, it takes serious calculations and extended testing to make it proper. If it's too high or too long on one side it might make irreversible damage. Have a bit of patience, it's surely coming out.

[mattcaron]

I had a few different thoughts as to how to respond to this.

Firstly, thank you for your statement of reason and rationality, including the implied and accepted statement of "if you use this on a GNX you will void your warranty". I am duly notified.

Now, you don't know me, so let's start there. Here is my resume: https://www.mattcaron.net/resume/. What's not on there are my extracurricular activities - I modify firearms and load custom ammunition for them. I modify cars for power and handling as well. One evening, whilst engaged in some spirited driving in an attempt to scare my wife, I broke the clutch, I managed to get the car into second and drove home like that. The next day I had a new clutch shipped to me, dropped the trans, changed it, and put in a short shift kit while I was at it. When social media decided to annoy me, I left it all and set up a private Matrix server for the few people I actually care to talk to - complete with private encrypted video chat. I do my own home maintenance - electrical wiring, carpentry, plumbing, and the like, and brew my own beer (because most American beer is overly-hopped). I also like instant gratification, which is why I've always liked computers. I'm a grumpy old Unix hacker (Solaris, then Linux), complete with beard, who generally plays with microcontrollers these days (check the Github linked off the resume if you want to see what I'm up to). I have 3 3D printers - 2 filament and 1 resin; all heavily modified.

Now, given all that, do you really think that either by skills or temperament I'm going to be able leave well enough alone, or be patient? Besides, what's the worst that can happen - I break the GNX base and have to buy a GF base?

However, as I mentioned elsewhere, I have a GF + SCG-R (from wife) and a GNX + SCG-L (from mom) which will be waiting for me under the Christmas tree. If the GNX omnithrottle is out by Christmas, then I'll put in an order for it (and probably some other accessories like a small GF baseplate and such), mainly because your boxed solution will be better than my homebrewed one (no dispute there). If not.. well, time to warm up the printer and the soldering iron....

Now, after all that text wall, if the adapter won't be out by Christmas, and you wanted to ask the engineers specifically what the connectors they use on that cable are, and then pass that information along to me, so that I might void my warranty, I would be ever so grateful.

@ mattcaron:
As stated here https://en.wikipedia.org/wiki/JST_connector
the cable you posted (XH series) is not useful because is 2.50mm pitch
You need a 1.25mm pitch cable, so GH series.

I guess that the black cable entering in the gimbal is a customized cable, but surely it uses a GH connector.

Here you can see some pictures I have taken from my 200mm extension. The light is not good but the resolution is enough to see the details. I think they don't present a clip to release.

I bought some cables from this announcement: https://www.aliexpress.com/item/1005003354354307.html
but I selected the wrong shipping and I will have to wait a lot (if they arrive), so I cannot confirm if I chose correctly, but I am confident about it.

[mattcaron]

So, a few things here.

1. The cable from the GNX tailpiece looks different from yours. See pictures here: https://owncloud.mattcaron.net/index.php/s/Q4kiJS5MtpQtnfZ
2. I believe the GH connector is correct, because it has the clip. Good find. I will investigate further.
3. The picture from your extension is what I would consider a "normal" JST, the kind that I'm used to. There is a center part that makes sure you don't plug it in backward, but, as you say, no clip. It kind of looks like the SH type connectors, but smaller. I do not see it on the JST wikipedia page.

But, I think JST GH is what I'm looking for, thanks for the help.

Edit: https://www.amazon.com/Connectors-Sides-200mm-Length-Wires/dp/B01IZAX8ZA looks like the correct thing, but short. It's not a replacement, per se - I'd have to cut and splice an extension, then fish it through the twist adapter tailpiece and then hook it all up. But, I bet it would work, and I wouldn't hack up the original so I can always put it back to use with an official adapter. I guess I'll see if an official one comes out in the next month or not.

That was an interesting read and a straightforward attitude that I enjoy. Now, about the extension, it wasn't supposed to be a warning, but more like a heads up. We support modding on our devices as long as common sense is prevalent and not brute force.
If you'll decide to go rogue on the GNX you actually need only a longer cable and crimps for its ends; the existing connectors could still be used with the new cable.

I am not sure that you are understanding correctly of what is composed an angled throttle; just to make it clear: in any angled throttle that you can find in internet, the both ends are the same ends that you will find in an VKB extension so, apart from the JST discussion, you will always need a VKB extension, disassembly it and atach both ends to the ends of the 3d printed extension. Only if the 3d printed extension is longer that the cable that comes inside the vkb extension, you will need a cable compatible to make it longer, otherwise, you can use the same cable that comes inside.

So, the cable from the GNX tailpiece cannot be different that mine, because that tailpiece must be one end of a VKB extension with its original cable. The black cable surely is a custom cable with a thermo-retractable cover.

Except there are no GNX extensions, only GF extensions. The GNX is not designed to be used with an extension. So there is none to buy and take apart. And the GF tailpiece has the circular 3 pin pad connector. In the GNX, it is a cable you pull into the base and plug in.

Indeed, but I needed to find the name of those crimps, which was my question. Fortunately, I believe joaquinbaeza correctly identified them, so I seem to have an option.

And I have to say that VKB's "take it apart and change things out" attitude is one of the things that sold me on the product line. It may be a little overwhelming to some people (138 page manual... For a joystick????) But I love this stuff. Been working my way through the manual as my light evening reading. It's like the company is made up of people who make stuff the way I would, so it's a natural fit.

The board has this BM03B-GHS-TBT.

Thank you so much for this information. This is perfect.

Yeah, you are right, my bad. I thought GNX and GF used the same connectors.

[joaquinbaeza]

Good News and Bad news: the good one is that the cables I bought from Aliexpress arrived today. The bad one is that they don't fit in the connectors that are used in VKB extensions, actually the cables I bought, 1.25mm pitch, are much more smaller. So, the conclusion is that the pitch of pins in VKB extensions' connector are more than 1.25mm, but I cannot measure properly in this moment to correct my former measure. I'm very sorry if someone took the wrong decision based on my information.

Moreover, the cables I bought are female on each end, rather than male and female, what is necesary to make longer the extension's cable.

[mattcaron]

Looking at the photos you posted and http://www.mattmillman.com/info/crimpconnectors/common-jst-connector-types/, it looks like it might be PH, which would make it 2mm pitch.

Also, if you can only find double female cables, could you just buy (or make by cutting and soldering) a very long one, replacing the original rather than extending it? That is what I plan to do (if needed).

I appreciate your tips (nice site also). I will try again with a different series.
