I played a little with the traces.
Good outside the box thinking. Still not enough room for a centering ring but heavily trimmed it might fit. Here is a version like this:
Thanks to both of you for working on this for us! :+1:
Interested for sure
Dam i am not really good with anykind of photo/paint software. Could you please remove all parts inside the red circle? Then put the 6 o´clock Led in its right place but rotate it 90degre. I have something in mind but i have to see it to check if it would work.
Like this? I didn’t want to move all the traces only to put them back but this should get the idea.
Its ok now i can play a little.
Have to get my mind from the today delivered light (https://de.aliexpress.com/item/Dual-Cree-XM-l-U2-Led-Torch-2-x-Cree-XM-L-U2-2-U2-5/1987840494.html). I will upload a few pictures in a new thread when my cam is reloaded. A few very big noooooooo goes. A 3mm deep hole underneath the ledboard (from the drillbit tip). Scratches all over the host. A dent in the battery tube. Sratched lens retaining rings. Some kind of residu on the reflectors. ultra cheap plastic lens instead of the offered glass lens. And can someone tell me how many bond wires i should see when i look at a cree xm-l u2 led?
Do not get me wrong this host was bought to mod it anyways. But some things (like the cavity below the ledboard) are a really bad start.
A small divot below the LED won’t make a noticeable difference if you fill it in with thermal paste. As long as most of the star has direct contact it will be fine.
What you have to worry about are any bumps under the mcpcb, those are very bad.
I think that you can get even more space if you arrange the traces a bit more precise than i could do. But this should be a solution that gets you the most possible clearance arround the led. But after a good night of sleep i maybe come up with something better.
Interesting idea but sadly I don’t see it making any difference to the important measurements. The LED pads are 7mm x 7mm, so it doesn’t matter which way we rotate it, the clearance will remain the same (we can’t move the LED itself without it being mis-aligned from the reflector).
The limiting factor in this case is how far from the LED we can get the resistors. I think your last idea is the best we can hope for. Although I did just realize that we are actually encroaching on the 9 o’clock LED some, I need to move that resistor some.
I don’t see things being improved by any notable amount past that just due to the limits of the mcpcb size.
The mcpcb size is not perfect for all the things we want to put on it. But i think that we are getting really close to a design that is working. And most modders will be able to do with it what they want (make a awsome light even better).
I hope nobody will find anymore flaws in the design (if so speak up !!!). If it is ok and nobudy has to add something i would like to get in contact with BG or KD in the near future.
@Texas_Ace
If you are ready with the final design, would you please upload a pic? So everyone can have a look. I hope that this will be a good solution for most modders!
far as I know the design has not changed from the last one I posted. When I get home I can upload it to oshpark. Although most likely banggood will remake it on their own software and just use it as a reference anyways.
Well, you did say this just a couple posts up:
Oh yeah, I forgot about that slight resistor change. Been busy the last few days lol.
I will get that change knocked out and the design updated and uploaded.
Is BG gonna be the seller? I was hoping for KD, as they were mentioned also. I like KD a whole lot better and this board seems to fit in their line more then it would at BG. KD has a lot more FL DIY related stuff.
The idea is that if BG sold it they could bundle it in with the Q8 purchases saving time and shipping costs.
I was under the impression that bundling was not an option as it would make a mess of things. Can’t really remember but I think it was mentioned in the Q8 thread regarding optics or something else.
Yes this is a stand alone thing, but of course putting both in one order if they are ready should be ok
(though still I so like splitting things so unless paying for shipping would not do that myself)
