Emisar D4S review

maybe Close Encounters tones/colors?

Nice idea. But If you do the easy way I-m really happy with two colors to determine if I’m above or under about 3,5-3,7V.
I recharge my batteries if they are under 3,7V

I recall passive voltage indicator methods, like different resistors for different color LEDs, were attempted… but they didn’t work very well or very consistently. So I went for a more active solution, using an attiny13 to measure voltage and explicitly turn LEDs on/off accordingly. The scale was red for the lowest voltage, then yellow, green, cyan, blue, and purple for totally full. Basically just a 6-step rainbow.

And the emitters were arranged in a circle so it would spin while going through the colors in order. Because bling.

Wow, wow, wow!!

Finally a 26650 quad!!

Any battery suggestions?
Flat or Button top?
High Amp but how high?
Manufacturers recommended and ones to avoid?
Max dimensions?
Assume not protected…
Thanks,
Nite Shadow

edit: prices back to normal, somehow my browser had probably switched to Australian dollars (exactly 35% more) and then switched back on its own

Intl-outdoor just increased the prices for all the flashlights and accessories +35% :frowning:

Also the original before prices were “fixed”.

Left new, right original:

edit: using a German VPN gives me the old prices

Noooooooo :weary:

Now the prices are back down for me as well. Thank god.

That is a false alarm :slight_smile:

Thank goodness because I was about to purchase a couple meteors as gifts.

Jeez, I wanna be friends with you! My friends get MUUUUUUUUUUUUCH cheaper lights than that!!!

Well then you don’t want to be friends with me, you want to be friends with my friends. I tend to be the “cheap one” when it comes to gifts.

just got my d4, take my money, i want the d4s now.

I was going to get a D1S or Mini GT.
Think I will get D4S instead. :wink:

Emisar? You just know you need it. :sunglasses:

I want it in silver (white).

Basically I could add the Maxim chip that I am planning for my LVP Tail boards as well to the aux board, but there is like no chance to make it fit on the normal d4 for size reasons

It is planned to do a color change on low voltage and shut down at LVP

Problem is I am waiting on the first to be delivered even if I ordered them 4 weeks ago
so first I have to test the tail boards successfully and the basic aux boards

It would help to know the optics and MCPCB specs on the D4S

on a Fireflies light the low battery and LVP shut off fits barely on 2 layer from space and trace routes

Impressive work Lexel, I wasn’t too excited about all this but you make me want in! :slight_smile:

Well looks like I am glad I put off ordering my D4 yesterday! Can’t wait for this to come out!

I’m just about to order some cells for my D4’s 18350 tube from NKON. While I’m ordering I guess I should pickup some 26650 cells ready for the D4S.

Would either of these be suitable?

  • Efest IMR26650 32A (64A pulse) 3500mAh
  • Efest IMR26650 35A (50A pulse) 4200mAh

Or other 26650 cells I can choose from

I’m not sure what the current requirements are of the D4S.
