Cheerios!
I got a shipping Notification 10 hours ago.
Nice, mine’s on it’s way too.
It all depends on the shipper and its location when the holiday starts. If it is a Chinese company it will definitely sit if it has not left the port. They usually, unless using surface mail, work 10x harder to make up for the lost volume so until they hit the weight barrier they double the efforts.
Hey guys, for anyone who has a courui already, perhaps you’ve seen my thread on the brand new design buck driver I’m making. Anyway I could really use the measurements of the factory driver so I can get to work. Can anyone help me out?
Also if someone has one they don’t mind not using for a few weeks or so I could do an even better job if I had a driver in hand, I would gladly supply you with one of the first ones I get together in return for you sending me yours now.
I have added the link you posted in the OP. Buck driver design - component selection example
For easier reference to all modders/enthusiasts, the thread below is now added/consolidated in the op:
Teardown and Mod Thread of Courui XML2 Aka “Big Head 3×18650 Side-Switch Thrower” (by LinusHofmann)
I feel like venting a little. So, here is a little rant. Feel free to not read it.
I’m tired of getting tracking numbers that don’t track anything. My Courui is marked as shipped and has a tracking number that I paid $1.99 extra to get. I try to track it and it says nothing found. It seems to be the natural state of the world now that tracking numbers are not updated properly or something. I bought an Olight i3s on eBay on the 10th of September. It had a tracking number assigned to it within a couple days. But, not until yesterday did it show any activity at all (Processed through sort facility). Do people not realize that the reason we want tracking numbers is so that we can actually track something? It’s really worse than not having a number at all, because it creates an expectation. Especially, in this case (the Courui), when I paid extra for the privilege of having tracking available.
Tracking shipments has been done for decades, at least by Fed-Ex and UPS. The technology, the processes, everything has been worked out. If they can do it, by now anybody should be able to. There is no reason why a shipping system can’t get tracking right. As for the seller, they are perpetrating fraud when they give a tracking number that is no good. Perhaps they are generating a label, which provides a tracking number, but holding the package and not shipping it. In that case, keep your worthless tracking number until it is worth something - after you’ve actually shipped my items! Until there is something to track, you aren’t doing me any favor by providing a tracking number to me.
Just to be sure, let me clarify something. I’m not ranting about long delivery times. I know that is just the way it is sometimes. I’ve learned to expect long shipping times and be pleasantly surprised when the shipping time isn’t very long. I just can’t understand why “tracking” isn’t consistently tracking anything so many times. It would seem to be so easy to get it right.
Make sure you are using the real tracking number and not just the order number which looks similiar…
There is vacation in china so I guess all our shipments are on one heap for some days before they get tracked.
I used NL post which isn’t trackable but gives shorter delivery times to my country so I can’t check if it is a singular problem
I like to track my shipments, I have the parcels app and it’s quite fun to have an overview which shipment will income next. But I also like the Christmas like surprise packages I have already forgotten about.
It will probably update once it gets in the country
That’s how I do it ;-).
In my experience with tracking numbers I received, regardless of postal service/vendor used (China free shipping), the tracking numbers usually goes active other than “not found” at about 7 to 10 or 12 working days. I’m happy if it goes active after 5 days.
What I don’t know is if your parcel shipped Sept. 29th was able to ‘escape’ the Oct. 1 to 7 China Holidays.
Btw, I almost always use this link to track: http://www.17track.net/en/result/post.shtml
Thanks, tatasal. That has been my experience, too. That’s the part I don’t like. I guess I’d be happier if they didn’t give me a tracking number at all until it goes active “at about 7 to 10 or 12 working days”. But, then I’d still be worried about whether they were ever going to ship it or not. :~
I’m hoping my shipment made it out before the holiday, but since I have a useless tracking number, I can’t know whether it’s moving or not. It would be better if they would assign the tracking number only when they are ready to scan and make it active. That would require that they change the way people are able to print labels at their home or business. The tracking number would have to be assigned only after the shipper had the package in their possession. They’re not going to do that. It’s much easier to generate a tracking number when the label is printed and just make it active at the shipper’s convenience. Especially, when you consider a business with the shipper coming to pick up multiple packages. The label is applied, the tracking number is there, and it can be scanned as received by the shipper before being put on the truck. But, giving away inactive tracking numbers makes lots of bad things possible.
Haha, this is the part that I don’t like either…but as I said, that has been my experience with shippers/tracking numbers that until now I really don’t have an idea how free-shipping, with or w/o tracking, China post works. (but at least parcels with tracking will give you an idea if you are already losing your parcel, haha). All the vendors that I have dealt with before can’t fully-explain how it’s done (as compared perhaps to USPS, etc.) That’s why we always read posts of surprisingly fast shipping AND snail-paced parcels, or something in between, even from the same postal service.
Talk about the consistency of being inconsistent!
Just got my first Courui in today, ordered from KD before I found out about the GearBest deal. Been going through the threads, and can't find any stock output #'s on it, even throw -- weird. So, this is what I got:
On 3 fresh LG HE2's: 2.6A tail (one cell), lumens: 734 @start, 734 @30 secs, throw: 75 kcd (taken at 5 m)
I'm quite impressed by this light stock - not what was implied in the threads. Maybe they changed things? I didn't do anything but apply Nyogel on the threads, and broke the o-ring at the head joint. Plus the e-switch stock driver isn't that bad either - with 2 simple hi-lo modes, and strobe available via long hold. Mine came with a big aluminum 25.8 mm MCPCB that fills the recessed shelf. I would not call the LED centering piece as overly high at 1.80 mm. Maybe they changed it to a lower profile one?
Also amazed of not one little droppage in output in the first 30 secs. There is some intermittent flicker, seen in the lightbox and during throw tests, plus noticed it testing. Not sure of the contact of cells to the driver or what. I'll probably first try dome wire upgrades and simple resistor mod first - maybe a big 31.5mm MaxToch MCPCB...
Thanks for the update, Tom E.
Hoping to see more of your posts here in this thread.
Oh well - just took out the shelf, starting to size up options and looking at using a MaxToch XM 31.5 mm MCPCB, and wouldn't you know -- the MaxToch is not DTP! I bought qty 3 from BangGood a few weeks back when they first listed them. I ordered a few 26's too and they all tested out to be DTP, but all 3 of the XM 31.5's tested not to be DTP. I just do a simple continuity test between the pad and the bottom.
Dang this hurts! They clearly advertise it as DTP...
Anyway, measuring it up against the Courui reflector, the reflector still overlaps about half the + and - pads. That is one huge reflector bottom...
That’s strange. The SN6X 2X reportedly has 32mm DTP MCPCB and it has been proven by a few here, however when you bought it separately it isn’t?! Does it mean the one they use in their 2X and the one they sell separately to you are different?
That’s a bummer about the pads - I just ordered some of them a few days ago 
You should still be able to ‘ghetto’ DTP them with a bit of elbow grease….
The Noctigon 32mm boards are really good quality, I will probably stick with them in the future.
My Courui, also from KD, was the same as you described, with the larger mcpcb, & good centering ring. It will be interesting to see what’s inside the one’s from GB when they start arriving.
Just got a return message from Terry at MaxToch:
Dear Tom
I am Terry, Amanda's colleague. She is on her pregnancy holiday.
I have checked with our engineer. Both 31.5 and 26 MCPCB are DTP @ 100 percent. But their manufacturing process is different. 26 size is made by CNC. 31.5 size is made by Metal mold, which processing precision is higher.
Thanks for your Enthusiastic feedback.
MAXTOCH Terry.
The manufacturing process should not impact it's DTP property - electrical continuity. Richard (RMM) has confirmed this and updated his product listing accordingly. Not aware it's been proven by a few here on BLF -- any idea where?
My response to Terry:
Hi Terry,
DTP means there must be electrical continuity between the center pad and the lower copper portion of the board. The 31.5mm versions do not have electrical continuity, so, can you please explain what in the design what non-conductive material is in-between the pad and the base of the MCPCB that is blocking the electrical path?
Since obviously my very simple test seems to directly conflict with your "100%" statement, can your engineers provide the design details of this MCPCB, similar to how SinkPAD does? Just look at the detailed design data SinkPAD provides here: http://sinkpad.com/sinkpad-presentation.php. It's very obvious their design is 100% DTP. Every SinkPAD and every Noctigon I've tested has electrical continuity between the center pad and the MCPCB copper base.
Please explain. I've notified the dealers of these MCPCB's that I am aware of, of this issue and one has confirmed my findings already.
Thanks,
Tom E
