MTN Electronics: LEDs - Batteries - Lights - Chargers - Hosts - Drivers - Components - 1-Stop-US Source

Of all people I wouldn’t expect the two of you to be steering people away from this. Tell us how to use a multimeter and where to modify the code to calibrate voltage. It will be within a few tenths regardless so either way it will be “safe” I think.

As far as ramp tables. I think this is something a google spreadsheet with some formulas could solve right? Lets make it and write a brief post on where to edit that piece of code.

These don’t seem like reasons to discourage savvy modders from attempting this. I’ve not done any of this and my lights work fine.

Not sure what you are asking... Think Anduril does voltage cal right in the UI, NarsilM doesn't - it should though. Temp cal is debatable whether you need it or not, based on how both version do temp regulation.

Ramp tables? What are asking for exactly? NarsilM has support built-in for a few ramp tables, so does Anduril. Right now, Anduril only supports "production" light configs while NarsilM supports custom drivers as well.

Basically, the driver types are: FET only, FET+1, FET+1+bank, and the tables may depend somewhat on the # of 7135's in the bank. In addition, there is 2 channel support for a buck driver. I think those are the primary variables, but there are others - what I/O pins are assigned to what, etc.

Not to my knowledge

Correct, I dont mean this. Both versions are acceptable as is.

Yes this

A little of this though it hasn’t been an issue thus far

I don’t see a “steering away” at all, just information to help achieve the best result…

All these replies and still no big announcement :weary:

Did that flicker problem ever get solved?

I’ve found a dab ofconductive lubricant after cleaning contact areas often helps.

So does checking and smoothing off the spring contact points, which often are chopped off with some kind of wire nipper leaving a sharp point that can make intermittent contact after it’s scraped a bit and given you a gouged battery with some ridges and hollows.

The tables can be generated by bin/level_calc.py in the repository. It typically requires some manual tweaking to get everything just right, but most of it is already scripted.

When people build their own versions for their own lights, it typically seems to work out pretty well. They can tweak everything to their liking, with all the options configured to taste. Making a generic version to sell on bare drivers for use in unknown hosts… is more tricky.

For example, take the relatively simple case of a FET+1 driver. We calculate a ramp for a light with one XP-L emitter at ~1500 lm. Then put that driver inside a host and run it. It’ll work well with a single XP-L emitter, but it’ll look weird when paired with something else. Give it a quad or something like an E07, and the ramp won’t look right. The FET portion will ramp up a lot faster than the 7135 portion. Or give it something lower-powered like a single XP-E2, and the ramp will look weird in the opposite way… the FET portion hardly even seems to go up at all:

That’s just one example, and a relatively simple one, but I hope the idea is clear. To get good results, the firmware needs to be configured and compiled for the specific hardware it’s used in.

Sorry, I , uh, may have jumped the gun in my excitement. My Bad.

TK, all that is well and good if you are OCD about everything being smooth and equal. If you don’t mind seeing the power level jump, it really doesn’t matter and can actually be a big kick watching it Roar! :smiley:

Just to be clear, Anduril is not yet available as an option from Mtn, correct? I’d like to try it in a mod, but wasn’t sure where to find a driver with that FW yet.

Simply look at the options on the website.

If you want a driver with Narsil or Anduril you typically need to buy one from Lexel.

Correct, it’s not an option there. Probably because it’s not that simple. Details about why were discussed a few comments ago.

Your best bet to find out what is available from mtn is to ask mtn…

Anybody try the Samsung LH351d 4000k 90cri LEDs from MTN?

How is the tint?

Yes, I ordered a bunch from MtnE. I like them, but can only speak for myself.

How do they compare to Nichia 219C?
Less green?

Less green, and more floody.

If shipping is too expensive from Mtn Electronics, you can get them in a whole variety of flavors, I mean color temps.

I have used several of those Samsung’s and agree with BlueswordM (not that my opinion adds very much to his). I think they are a decent bit less green than the 219C’s and I really like them a lot. I like putting them in S2s with an optic in front.

Maybe I missed it, what was the MTN announcement someone said a few posts back?

It never happened.

Actually, Richard bought D18s and SST-20s.
