And if you are ordering from MtnE he will reflow any in stock emitters for free, bare or on another board. He does excellent work. I have tried and it gets frustrating to get the 3 emitters and jumpers done and done right. I will never do a Tpad quad again. 3XP are easier but still… it will be done right from Richard.

No etc.
Carclo compatible only.
Round milled board with 5 drilled holes.
I can help with design to avoid usual problems.
Will take 50-100pcs from first batch and more in future.
Production methods and self-cost is same too other noctigon-style KD boards, so target price is $3.5 per 2pcs.

Yep I agree T-Pads Sick ! Make a 32mm triple board in the KD Black! I would really like it if they made both, dedicated parallel boards also, dislike using jumpers! Thumbs Up

A simple Parallel design similar to Manker, Mateminco, or who ever it actually is. But Must fit Carclo and have the Negative on the outer edge. Yes, with some Meat on the board, Not thin. Please.. Cash

Problems with traces short-cutting to the body can be simly fixed other way.

I want to mod my S2+ with a 219c triple.
I bought the LED´s from Clemence. Now i need the other Parts.
Will this fit? Driver is a MTN FET + 7135 Driver

- http://www.kaidomain.com/p/S024023.DIY-22mm-x-8_5mm-Brass-Driver-Pillar-... (will this pill fit if i add copper spacers?)

And i want to upgrade my UF-1504 with a new XP-L2 LED.
Which LED should i take for max output? Driver is a MTN FET + 7135 or a LD-2 with a 100K current resistor (= max 9A)

I will use US18650VTC6 as powersource.

I just got in an assortment of the KD DTP copper stars a week ago… I have to say, they are really nice. They are flat, black and dimensions are good. I will use more of these.

Thanks KD, now I will have to order more led’s.

received mine too, very good packaging and quick shipping. My triples aren’t flat though. They are slightly bent and only a good amount of sanding makes them somewhat flat. Having said all of that – they work 100%. If anything this seems like a cosmetic issue.

Now I need to buy more emitters and hosts.

Warning KD Black stars, de-doming a couple XHP35HD E2-1A’s in racing fuel, and the substrate is lifting, guess I have a couple more 20mm copper spacers!

Ooh, that’s not nice.. Sad
I wonder how they will hold up in regular fuel and other solvents..

I have a bunch of KD boards, and they’re all quite as flat as Noctigon.
Only the triple boards are deeper in the middle.

I did not try any triples, very happy with the Noctigon ones. I will have to watch them when removing domes, I always solder the led on before I soak them to remove the dome. Have not tried any of these in gasoline.

I hope that KD can get the new XP-L2-W2 LED´s until the BLF Q8 is ready to be sold.
This will be a lot of work and also not realy cheap but well worth. The Q8 + 4 new XP-L2-W2, a new XHP50.2 as upgrade for my modded TN31 (K40M driver with resistor mod and dedomed MT-G2 LED and i added a lot of copper to help with the extra heat), and a XP-L2-W2 upgrade for my UF-1504.

I have one question. I bought a few Cree MC-E RGBW LED´s. Now i need the MCPCBs.
Is this the right one for the LED?

And don’t go over 700mA per die, that is really close to the max already.

I want to use 5 MC-E Led´s for the Lamp. It will be a Lamp for the living room. The led´s are pointing towards the ceiling. I want to use Aluminium profile 40*40mm and 50-60cm long.
Then a remote controller like this (https://de.aliexpress.com/item/44-Key-6A-IR-Infrared-Music-Remote-Contro...RGBW-LED/32710601191.html) which is controlling 4 of this drivers (http://www.ebay.de/itm/1-Stueck-1000mA-KSQ-8-32V-Input-0-30V-Output-dimmbar-/351975399530?orig_cvip=true).
And each driver controlls one color. Powersupply is 24V DC. And finally i have to find a optic with a really wide spot.

@djozz would it be better to reduce the current to 500-600mA/die? If all dies get 700mA the LED gets a total of 2,8A. I think that this could get really warm without extra effort regarding cooling.

I love your project! Very nice:)

The full 1a per die may be a bit much if all are on at the same time. But then again, if it were me I would find a way to use the full power Wink Can you add some cooling fins or added heatsink to your aluminum profile?

Edit: Actually I see that 700ma is the max rated current for these dies. I don’t think I would top that especially without a direct path mcpcb.

Any opinions on this new (?) driver for 6V leds? http://kaidomain.com/p/S026606.H1-A-20mm-3A-1-cell-5-Mode-Boost-Driver-C...

Can it work with an e-switch? It would be nice in a Skillhunt H03 Smile

Finges I am currently working on a Narsil FET+7+1*7135 driver set up with thermal management

If the Narsil works out great I will have a spare H03 driver
The H03 one has too high voltage drops as the current has to go through the inductor and a small transistor
@3A the losses on the Skilhunt driver are 410mV, so a fresh 18650Q cell can reach 3A only with both springs bypassed for a short amount of time

And I dont like the timed stepdown
The UI is OK

An Attiny13A 7135*8 driver with eswitch firmware is also an option, but not priorized atm

You could get a XHP50 with boost driver in there, but I see thermal issues.

Does the H03 have a step down driver?
Does it work on 6 Volts too, or even 8.4 Volts?

No the driver I linked is for 1s only

Quote:
Input Voltage: 3V – 4.2V ( 1 Li-ion )

It boosts the voltage from 1 cell to power 6V emitters like XHP50, MT-G2 etc.

The H03 has a stepdown driver up to 8.4V

I have never ordered from them... Just found some tail switches I need badly and signed up ready to place my order and it says account not activated...

 

Anybody know a US vendor with 12mm*8mm*8mm for sk68's.  Ordering from anywhere else just ain't working tonight for some reason.
