35k views, I can handle apologizing again to the few you who cared enough to mention the focus problems. All apologies. You could also help us creators by contacting youtube direct and ask them why creators aren't allowed to edit or update video uploads, then this issue wouldn't exist along with many others of different types. We try, thanks for noticing. ;)
My diode laser just had a wire go bad making it unusable- the jst connectors fried and partially melted in one spot, the wires easily broke off just handling them. They're replacing the cable but it's going to take a couple weeks to get here so I ordered a small kit in order to repair the current wire myself. This video gave me all the tips I need in order to feel confident doing the job- thanks for it!
Thanks for the tutorial! Two questions if you don't mind. First, will this work with thin wires like 26-30AWG? Second, is there a way to do this without a dedicated tool?
yes, JSTs are sized by gauge of wire. And yes, I suppose you could do it with a couple of pairs of needle nose pliers, but I haven't the patience, eyesight, nor nimble fingers for such tedious work lol
that's a good question, according to digikey -it says "the mating housing has crimps", but doesn't say much about attaching wires except "have poke contactors", which sound to me like just wiring piercing connections, like a ribbon cable maybe. Sorry I don't know anything more about these particular JSTs: www.digikey.com/en/product-highlight/j/jst/sh-and-sr-series-connectors
Very helpful, but why do some JST-XH connectors have 3 ground wires and 1 red/hot wire? Would it affect anything if I solder all three ground wires to a single ground wire on another connector type of pigtail? I want to make a temporary cable that is JST-XH (three ground & one red) to a barrel plug (one ground & one red).
JST themselves don't have designation of wire - so whatever device you're working on did it that way for a reason. I probably wouldn't do that without tracing each ground to be sure they are the same voltage line to start with. Otherwise, if they are all the same, it shouldn't be an issue to tie them together.
yes, I realize that and apologize. I wish youtube would let us edit / replace videos - I would reshoot it. :( To "fix" it, I would have to repost a new video and delete this one - I'd rather not do that. :(
I'm not an expert by any stretch of the imagination but enjoyed your video and agree about the focus. I note the black dimensions on the die were in focus the entire time. Maybe a small silver object against a black background might be better for focus because of the contrast? Only constructive criticism as I loved the video - was exactly what I was hoping to find and found your presentation/time excellent. Looking forward to future videos.
y splitter? do I do that somewhere? lol the hood sensors maybe? Anyway, all you have to do is splice the wires, not try and get multiple wires into the connector pins - that's not possible.
Hey Chris i have a Hubsan 980mah pack with a regular battery lead and a red JST lead that plugs into my H123D Jet. The negative wire (Black)has separated from the pack at the point where the factory solders the wire to the pack. How can i fix this problem because this pack is still good and has lots of life in it? Thanks for your reply!
@@ChrisLocke1969 Hi Chris i was able to carefully solder the black wire to the new 980mah pack and it works like brand new(Thats because it is) i laid a small oeice of electrical tape so as to be careful not touch the other leads and i got lucky with your help!!I have one other pack that is puffy does that mean its no longer any good?
@@techFPV5964 that's great! glad you didn't get zapped! lol As for the swollen lipo, yes, that means its been damaged or overcharged, or is just old - gases have leaked inside the battery and are waiting to explode out. Recycle that one, is best!
sure, you can use whatever technique you'd like - the JST connectors just make it easier to remove the head, tail, and top covers when needed. But if you are using the PCB, it may not be easy to skip using those JSTs, unless you're going to solder directly to JST pads on PCB.
No because then you would have 3 pieces of exposed metal nearly touching (if not actually touching) each other, shorting whatever you are working on (because they won't fit into a secure connector).
@@ChrisLocke1969 I’m afraid us folks arriving now don’t care how many hours of video ago this was. Shame because it’s interesting content but mostly unwatchable for me. I appreciate your work, but it has to be said.
one in every crowd. Sooooooo sorry, but pretty sure I already mentioned that within 23 seconds of the video... and if you can't see what I'm doing because of a little focus issue, its YOU that's OUT of focus.
I kow you triede....but it is too out of focus and too far away to see the details needed to learn what you are doing.

Much informative video. Very Useful. 👍

Thanks for the review, I was stuck.
Glad it helped, despite the blurry video ;)
Thanks Chris, this was good information.....
glad it was helpful, and thank you for being kind about the focus issues - I wish I could replace this video, but youtube doesn't let us :(

HI, thank you for your video. Please any ideas how to wire the JST SUR 0.8mm connector? It seems it does not need any crimping.

Whats the machine called that will strip that waste strip off the connectors?

@@ChrisLocke1969 Thank you. It is to charge 3S batteries in a combat robot
Your explanation is very good - the video, however, is too much out of focus so that the overall value is drastically reduced. 😞

@@ChrisLocke1969 Understandable. I always wonder why they don't allow it. Perhaps because they fear that misuse would ensue.

hi chris,im having slight trouble, how would i go about making a y splitter out of jst connectors

I would think you're only option is to carefully resolder... but man, be careful!! shorting out a lipo can be a quite powerful jolt

@@ChrisLocke1969 Ok cool i'll get rid of the puffy batteries!
@@ChrisLocke1969 Hey Chris i was able to solder the ground wire back onto the lipo and its now working great. It was a little hairy tho!!
The proper crimper is the SN-01BM
Will this work with a 1.25mm jst connector?
The perfect crimper for 1.00 and 1.25 JST is the SN-03BM which can also be found on Ali
@@FransvandeKamp thank you
Thank you for the video
Do we need a crimper or can we use pliers
I doubt pliers would work... at least not with quite a bit of care and patience ;)
Can i just solder the thing instead of crimping.

Maybe that waste is supposed to wrap around the wire.
No because then you would have 3 pieces of exposed metal nearly touching (if not actually touching) each other, shorting whatever you are working on (because they won't fit into a secure connector).
I appreciate your effort but the entire video was out of focus..
maybe turn off auto focus and lock it to your fingers before you begin next time :)
thanks, though this was 50 hours of video ago ;)

Great
I appreciate the effort trying to explain this process, but everything important is so out of focus that the video is ultimately fairly unhelpful. 😐
thanks, and as was your late-to-the-party comment, since I apologized and explained in both the video and description and comment section.
Everything is OUT of focus, so I can't see what you're doing !
