Emisar D4S review

Lexel, are you looking for the smaller 4 holes in the 33mm MCPCB? I don’t have the D4S yet but I do have the boards and I do have a working X6 using this board. About to head to bed tonight but I can get measurements on the inside ring of 4 small holes if that’s what you’re looking for…. I get 20.0mm across center to center, so 10mm from center of board to center of the small inner circle of holes.

I should point out that this is using a set of cheap plastic calipers’, my good ones are out in the shop on the lathe…

Great stuff PBWilson appreciate the information and response. I may just have to get the shockli button tops then

Nice Job Lexel … :+1:

But why do I read there PL47 and Fireflies on the one design … ?

Can you explain me please ‘cause I’m thinkin’ about to get a second ROT66 (in 4000K HI :cry: ) but …

… maybe via PM ?

I saw someone posted D4S with red optics backlight? I only see cyan option at IOS.

Nice, I’d order a second light if red was available.

I was hoping Emisar would make a red backlight version. I am holding out until then.

As far as I have understood, those color-LED boards will be sold seperately in different colours?

Why not make a RGB-version, so people can set their preferred color themselves?

Ever notice how, when a manufacturer picks up the gauntlet and offers something new everyone screams MORE, you shoulda, you coulda, you oughta…… ?

Thank you Hank, well done! :slight_smile:

Red backlight looks sweet, I’m going to hold until new color shows up.

Personally I would’ve preferred a green mimicking tritium but brighter, but blue is pretty too.

I think the cyan will compliment the smooth green perfectly! :sunglasses:

Owner of this specific D4S said Hank custom made for him. However, when I e-mail Hank about the custom aux LEDs D4s, he replies “I’m afraid we are not able to offer such option.”
May it is just for China customer or for Hank’s group members only.

The aux LED board uses some common cheap LEDs and they shouldn’t be incredibly difficult to swap out. It’ll be useful to have hot air or a wide solder tip for unsoldering the stock LEDs though.

It looks like it uses the same type of LEDs as several of the clock kits floating around lately. I don’t know what type they are, but they can put out a lot more light than what the D4S does with them.

Sorry, are we still talking about lady toys?

Easiest way is to use two solder irons. Hold them on both ends and lift the led.

On the other hand it’s an excuse to get an hot air station :wink:

These LEDs don’t have much metal to grab onto, so I’m not sure the 2-iron method would work unless you have a third hand to grab the LED from the sides at the same time. That method works with resistors and capacitors, which typically have a metal surface to press the iron against, but I haven’t found these to work that way.

Putting them on the board is easy, but getting them off without destroying them is difficult.

This pic, when zoomed in, might show enough to explain why:

Solder wick might work!
