KD (kaidomain): Deals and new products thread

That’s a no-go. The MCU is the 10-pin chip, probably a PIC. The larger 8-pin chip appears to be a FET.

Oh. Yea I was looking at the 8 pin chip. Well that’s a shame. Who would design a powerful driver like this to START on turbo?

Its not about driver design. Its namely about whoever decides which software goes into the MCU, and the reasons behind. Likely many of these drivers are mainly software implemented for some sort of generic market or generic abroad market. The mode spacing in that driver is terrible, too.

The Chinese, It use to be alot worse than it is now but thanks to several contributing members here on BLF it’s becoming rare. At least most of them are making the strobes and flashes hidden after many years of complaining about them in the main UI.

I always wonder why.

How come these Chinese software engineers can’t come up with good original UI ideas?

Simple and not very well R&D is cheap. Complex and well designed is expensive which has to be added to the cost of each driver. The more time the software developers spend on a UI the more it cost. We are just very fortunate to have members who do this without asking for a dime or very little money.
I couldn’t even image the cost on the hours it took to develop Anduril.
Just my opinion. :smiley:

No and @#$% no.

“Ask, and you will receive.”

The above quote refers to a manifestation technique, which in recap is entering a theta wave brainwave state of mind (actually easier than said) and then precisely sketching out whatever it is to be manifested.

But, did you ask? And what did you asked?

First of all we need to come up with a common goal. I think something can be done here, something sort of establishing a default for number of output modes and sequence order, preferred mode spacing, memory type and hidden strobe (if anything).

For example: 4 modes low to highest, 0.1%/5%/20%/100% mode spacing, off time memory, double tap strobe.

Off time memory definition: memorizes last used mode if disconnected from power more than x seconds. This can be pretty short, like 1 or 2 seconds, as usually a half tap to change mode lasts less than that.

By opening a thread where others can see and chip in, vendors included, and once the common goal is set the petition would be formulated. Once formulated people would enter into manifesting state and command/pray the request.

This actually works a lot better than you may think at first, no need to say this to those who know.

Because the driver designers are contracted and dont actually work for the flashlight company. Also the driver designer dont actually use the flashlight or any flashlights in general so they dont have a sense what a good UI should be like.

3V XHP50.2 DEDOMED

New dedomed leds available at KD :+1: :beer:
(3V & 6V XHP50)

But there’s an error in 3V offer: no field for choosing mcpcb size and thus impossible to add to cart.
Can we have it fixed? Please? :innocent:

Looks sliced and diced.
I’m impressed.

Ban could work on his picture quality. But the slice/dice job like it looks from the blurry images seems not great.

The flip chips are safer to slice as the bonding wires are hidden and you can go fairly low when slicing. Id recommend people give it a go themselves might be a good mod to start with. Get a washer and razor and try.

Yeah I’m not a surgeon at all and only failed one on three attempt.
Last one is in my Astrolux FT03 :

Is there any point in going lower than the bonding wires? That is very little dome leftover thickness. When looking at the emitter from above and paying attention at the apparent die size, big change can be seen with dome versus no dome or as the dome is being lowered by slicing. At some point going down the optical gain starts being negligible.

:-)

The XHP50.2 has no bond wires. So you can slice right to the edge of the phosfor. It does have a few exposed ESD-wires but they are not essential for function and with a bit of luck you can even keep them whole.

Hi

I had added the stock for 3V version.

Thank you

Many times I’ve heard how slicing was hard to do reliably and expensive and not a practical option for anyone but modders.
Here I see KD offering something actually harder (because dicing reqiures some precision). Even if it’s not done great, I appreciate Kaidomain’s willingness to try to walk this not well treaded path. I appreciate it a lot.

Already spoke about earlier, imho most practical way is O:) dedomilling.

Ended up ordering a 25 piece feeler gauge set of blades, by the way.

Hi BanL.

Is there a chance that you can sell the triple Nichia 4000K 92CRI on a 20x1.5mm MCPCB? I see it’s only available on a 20x1mm MCPCB.

Hi Kevin

Please don’t worry.

All our triple led had upgraded to 20mm (D) x 1.5mm (Thickness) once.

I will update to all the descriptions.

Thanks

Ban
