That thing is a pure beast. Love to see a pure copper version.

that would be amazing

[Texas_Ace]

Ok, just got word, this weekend will be the end of the group buy.

So anyone that wants a WT90 at the GB prices grab them while you can!

[TermsakC]

Quite surprised to see the slow sale of the WT90. The Black version hardly moves on Ali Express’s web page for days, still 51 pieces available.

I have grabbed one Silver. Will wait to get one Black if the price drops later this year.

BTW, what happens to those large and expensive flashlights (each costing over US$200) which have been left unsold over the years? Just saw on Olight’s website, soon the new X9R will be on sale for about US$500. What will happen to the older Marauder 2, which is priced over US$200?

[Rayoui]

X9R has been around for a while. Marauder 2 came after it. The only thing that’s new is that it’s blue now. I imagine they will continue to carry both models. The X9R will go back up to $600 when the sale ends.

[zoulas]

The same thing that happens to anything that does does not sell. Flashlights are no different.

I ordered one of the silver lights for myself so I will have one around to mess with as well before long. If anyone else wants to remove the charging from their carrier and can’t do it themselves send me a PM and I can see what options there are.

Thank you TA, I will re-read everything and see where I stand. I like the idea of keeping the charging. But if solutions for the light have been worked towards, I will def weigh the overall benefit to the light. Will removing charging address some parasitic drain and the glowing LED, or just the residual drains?

Disabling the charging on the carrier should remove all parasitic drain from the carrier leaving only yhe normal parasitic drain from the driver itself which generally takes 2 years+ to drain a set of batteries. Sadly I do not see the charging parasitic drain being fixed while keeping the charging working. This is why I don’t care for internal charging. It can be done but takes a lot of extra work to make it work properly.

Hi TA, It is possible for a "mere mortal" without too much experience to be able to disable the charging on the carrier ... I wish I could do it because I always use a spare pair of batteries and I prefer to recharge the batteries with my charger.

For one, if I remember it well, Narsil has the option to switch off thermal regulation while Aduril can not. (correct me if I’m wrong). That alone makes it worth to have Narsil on the WT90 for me.

yes, great point, and you are correct about the capability of turning off thermal reg on Narsil. And I am pretty sure you cannot on Anduril, but I don't know honestly. And that is also a huge reason to have Narsil on the WT90, which I forgot about! Thermal reg is also the biggest drawback to my mf02sv2...

A way to turn off thermal regulation in Anduríl is run it on Turbo for minutes and tell the lamp it is 18 degrees C.

Excuse me how do I tell the lamp 18 °? I can calibrate the external temperature or the temperature of the room or you are telling me that after heating the lamp with the Turbo for a few minutes I tell him that the room is at 18 ° so that it who is hot thinks that all that heat is only 18 °, is that correct? Thank you.

Easiest way would be to simply replace the charging PCB with a pass-thru board. Should be cheap but Int'l shipping is always a problem. We do need the PCB board designed, then anyone could order it through a PCB service like OSHPark or a China based low cost PCB house like https://www.pcbway.com/. Not sure of the cost, but probably over $10 shipped.

This is about Anduril, not the WT90 flashlight as shipped.

With Anduril, to calibrate temperature, you tell it what the current light's temperature is by clicking "nn" times, like 18 times for 18C. So what he's saying is to calibrate the light way under what the true temperature is, therefore it effectively disables thermal regulation because if it's set to trip at 50C and the real temperature of the light is 50C, the processor thinks the temperature is only 5C, for example, and won't drop the output via thermal regulation.

[Tom_E]

Btw, I just quoted a 50x50 mm PCB at PCBWay.com and it came to $5 for qty 5, plus shipping. USPS shipping for US is $10 but there might be a cheaper option with them.

Qty 5 is minimum, but qty 10 costs no more. I'm not sure this board can be made and quoted that cheap though - might depend on other options, for example, if the thickness is greater than 1.6 mm, the price goes to $53!

In the end, I believe that paying VAT and shipping from China is not worth it. I am waiting for an already modified carrier that I believe will arrive sooner or later and I will buy that directly, by the way why don't you propose it to us TOM E, it would be a pleasure to buy it from you.

[Tom_E]

Unfortunately I haven't had the time to spend to teach myself PCB design. Not sure if TA was thinking of doing it, or how easy/difficult, etc.

I'm not well experienced with Int'l shipping, either, but from past experiences it's not cheap.

[Texas_Ace]

I asked if they have the PCB design files for the charging PCB. If so I should be able to modify them pretty easiely and could order a batch.

If not then it becomes much harder simply due to the precision that the mounting holes have to be and it being hard to properly align said holes. It can be done just a lot more work to start from scratch.

If you have a hot air gun it is not hard, just remove everything and bypass the FET’s.

I am going to try testing if you can only remove the charging IC as well when I get mine.

[ArtieT59]

Id be interested in buying a pcb if cost with shipping is under $20.

Easiest maybe is if a pcb design is uploaded to Oshpark , even with the newest tax rules my guess is that it is around 10 dollar shipped worldwide. The only downside that you get 3 pieces instead of one.

[Tom_E]

Can anyone measure the thickness of the board? I can't right now. OSHPark only does 1.6 mm boards, least at reasonable prices.

Mine reads 1.5mm…

[Tom_E]

Sounds close enough - if 1.6 mm works, price will depend on board diameter, though I'm not sure about the cutout requirements (recessed screws, etc.).
