TK's Emisar D4V2 review

[Mark_M]

Could there possibly be a short in your adapter? What command did you use?

@DB Custom

That’s right BurningPlayd0h, we as end users have responsibility. The very power source this light demand has it’s own level of end user responsibility, totally up to us to be safe within the parameters of the tools we purchase.

And now y’all know why I’ve never been eager to build lights on request. The sheer power of an unrestricted hot rod, especially a small quad, demands a respect I just don’t see coming from the thousands of new members. We once were a family of enthusiasts, pushing boundaries and making things happen. When we started getting manufactures to build “Custom Hot Rod” flashlights, well, our membership level flooded and the problems arose. And we have lost many a solid member in the process, tired of dealing with the inevitable growing pains.

If the early adopters learning phase were still present we would be golden, but the entitled masses are ruining the spoils. I feel it strongly myself, as one of the people that has pushed limits here for years. After spending so much time building test drivers and hot rod lights, and sharing the process openly so others could find the same results, it is very discouraging to see all the whining and carrying on over such a simple development as a bug. Y’all apparently never spent personal funds on Knucklehead PCB’s and the ensuing component list, or worked hours building experimental drivers for this forum only to have to buy the next revision and start over. Stuff happens, get over it.

I have never understood the desire for a built hot rod and a muggle mode to throttle it down for babies to play with… pretty sure I built one of the first 3000 lumen + quads, and it ran on a AA sized 14500 cell. It was promptly used to run a bear out of camp. Safe? What’s that?

If you buy a hot rod, you have the responsibility to control it. If that means Not using a mode, then don’t! All of the electronic switch flashlights exist in an open power environment, one tiny failure and they’re ON. I can’t count the number of glitchy e-switches I’ve replaced. If ultimate no brain safety is required, use an inherently safer light with a mechanical switch and either alkaline cells or protected Li-ion’s. No simple muggle mode is going to protect an idiot from himself.

+1 The more I think about it, the more sense Hank’s original desire to not have muggle mode on his lights makes more and more sense.

[Firelight2]

I don’t think that’s the issue. The bug could have happened with a different portion of the UI besides muggle mode and we’d have the same problem we have now.

Muggle Mode by itself is fine. The only problem is the bug.

You have reflashed many lights, but had no success here? I have no experience in mods,flashing, or soldering, yet I am told that with the proper equipment, it should be easy. I saw in your previous post that you put together your setup. I’ll bet that when Hank’s setup becomes available, you can successfully reflash this light. It’s too bad your friend may need to wait for his light.

Absolutely no shorts. Ichecked before first use multiple times. rechecked now. All wire connection goes to pins so no contact problem either. The light aux led turn red blinking when connect the pins.
This is what I used:
avrdude -c usbasp -p t1634 -u -Uflash:w:andurild4v2.hex

My take on the situation:

I like this well reasoned and thoughtful post.

I flashed more than 200 lights.
My “friend ” messaging me every day multiple times when he can pick up his light and he wanted to came wednesday. Now I can’t tell him to wait or I can’t pay him back and we are here with a worse light than it arrived. He is not a patient guy. So I am sure if I need to wait a month again he wil messaging me every day…. That is why I usually don’t buy lights for other people. If something goes wrong I need to do warranty things or repair lights or loose money. The pin connector is OK I don’t think another one do the job. Maybe some fuse settings missing from the line. Usually flashing scripts have fuses. I don’t know why this not have.

specific name of the file is

anduril.2019-07-18.emisar-d4v2.hex

I know. Downloaded and renamed it to a shorter name. That name is in the command.

You said it starts at Max ramp, can you ramp down? TK stated that as long as the fuse values are not changed then there is little risk to brick. Have you tried reflashing? Maybe it is set to manual memory and it was on Max ramp, did you try 5h to switch to automatic memory?

yes I can ramp down and seems other things work just it always start ramp max with short click. long click it starts moon then ramp up.
The flashing sequence not even completed once. I tried it many times and not doing the flashing sequence.

[Mark_M]

Try changing it to automatic memory.

[ZozzV6]

@Mark M

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

@Mark M

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.

[Valynor]

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

@Aprilis

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.
