TK's Emisar D4V2 review

Try changing it to automatic memory.

changing what to automatic memory?

[Mark_M]

While the flashlight is on click 5 times with you holding the last click, there are two types of memory now one is manual and one is automatic.

I did not know this feature existed in Andúril. Thanks! It worked. Now I have mode memory but still have the bug firmware I think

You don’t have a physically defective product. You have software with a bug. There is nothing wrong with the hardware in your flashlight. It seems to be a real stretch to try and argue what you are. Do you attempt to send back your PC to the manufacturer anytime Windows has an error?

:+1: :+1: :+1: OMG that’s the best reasoning I’ve seen. I remember back in the 90s when running the x86 and Pentiums that cost over $2k+, I spent more time trying to figure out DOS and Windows 3.1 crashes, bugs, hardware drivers not working, etc., than actually using my computer. Windows Xp was the first windows stable enough to use without constant fear of crashing and losing work, but it still had its fair share of problems. Apple IOS is probably the most bug free OS I’ve ever seen but it is developed by thousands of engineers and hundreds of billions of dollars, whereas Anduril is developed by a single non profit hobbyist and Emisar is likely not even a registered business operated by a single flashlight enthusiast from his home.

No problem, I think it was added with this flashlight release.

ZozzV6, you should probably take a look at the Anduril manual: https://bazaar.launchpad.net/~toykeeper/flashlight-firmware/fsm/view/head:/ToyKeeper/spaghetti-monster/anduril/anduril-manual.txt

esp. lines 49-65

Could somebody help me please? I am having trouble with getting to the maximum regulated output of the flashlight. How can I get to the maximum regulated output without manually trying to catch the exact point where the light blinks? What is the easiest way to do it?

Easiest way to get there is losen tailcap (wait ~3 seconds), tighten back up again. Click to turn the light on and it will be at max regulated output.

If you want to use that level often you can save it as manual memory (5 clicks from ON while you are at that brightness).

Thank you so much!

I have all the lights from Emisar and they are all great in their category. Still add USB C recharging and D4 V2 would be even better. If it were possible to connect to the data via USB C, it would be a dream lamp.

Heck yea, if Hank adds USB-C charging to the D4 and 8x7135 making it a more practical light, I would buy 10 of them! Seriously!

I do not think I’d agree with this reasoning.

• Flashlights are generally considered to be complete units that should never need updating. Most people do not buy a flashlight thinking they’ll need to update the drivers like you would on a PC.
• A windows error on your PC is unlikely to cause physical damage to your computer or possibly start a fire. That’s not the case with the Muggle Mode bug.
• The D4V2 requires special hardware and software to update the firmware and is clearly not designed to be serviced by the average consumer. Unlike a PC where you can download a patch during normal operation.

My conclusion is this bug is a product defect and it should be treated as such.

Firmware is not the same as software.

If you bought a PC motherboard with faulty BIOS and no easy way to update it, you would indeed be entitled to return it.

The flashlight and firware are sold as a unit. It is a finished product, not a kit. To argue that the warranty does not apply is foolish.

Perhaps you don’t have the bug firmware. Look at the bottom of the revised Anduril diagram. There are instructions there for doing a factory reset.which is a new feature that was just added to Anduril along with the bug fix. If your light resets to the default values, your reflash was successful and you shouldn’t have the muggle bug.

Flashlights are usually assumed to be complete units that shouldn’t need updating. Most people don’t buy a flashlight thinking they’ll need to update the drivers like you would on a PC.

Usually, yes. The Emisars are not usual flashlights, though. Most people outside the flashlight community don't know they exist.

As it was said before these are clearly lights made for flashlight enthusiasts. If you can master the Anduril UI completely you can probably also do the firmware update IMHO.

Even inside the hobbyist community on BLF, none of us buy flashlights with the expectation that the firmware MUST be updated.

I suspect very few on this website have ever actually flashed updated firmware on any of their lights. I think flashing firmware is considered even on BLF to be an activity only for advanced flashlight modders.

Some good might come of this muggle mode bug though. As a result of the bug, more enthusiasts are likely to purchase the flashing hardware and give a shot to flashing their lights. This might open up modding to a whole new group of modders.

The turning on bug still exist. and no reset feature.
I told the flashing sequence not runned down any time properly.

Only this automatic and manual memory was new to me. I am using anduril earlier than any factory flashlight. Just don’t read every update manual. But the bug still in this light and flashing is not working.

@Firelight2

This has already happened to 2 people. The head of the light suffered damage such as melted optic, damaged wiring, button popping out. No other significant damage occurred. The lights did not explode and no nearby combustibles caught fire.

That said, I suppose combustibles could catch fire if something flammable happened to be in front of the head of the light.

Is there a link to these two videos?

They were not videos, just forum posts. One post on BLF and one in a German forum.

Ah I see , I’ve already seen them posts ,a. Video would be nice though.
With a quality cell like a 30Q I suppose the battery would be non deadly but I’m thinking if muggles had been running it with a fake or a cheap Chinese crapfire cell it may have exploded.
