New 4XP Noctigon MCPCB for quad optic

I’ve taken to doing runtime tests with the flashlight immersed in water to test what the driver can really do without the interference of that pesky thermal regulation. This, of course has very little bearing on any practical use case, but there do exist some fairly strong boost driver lights that have flat output if they don’t overheat.

On the other hand, ToyKeeper’s review demonstrates that the D4 puts out considerably more light on a ~50% battery than the 1500 or so lumens of a Wizard Pro.

If you will repeat this with D4 and it will pass it well, this will be best waterproof test.

LOL, good point. It’s hard to compare 1500 lm with regulation to 3800 lm without regulation. Or 2100 lm on a half-full 18350 cell without regulation. In this case, even a half-full cell with a fraction the capacity is putting out more light. Apples and oranges.

I’ll have to see if I can simulate that Wizard Pro by setting the thermal ceiling low enough to limit it to 1500 lm, and then see how flat the graph is. It’ll be a good way to make sure the regulation isn’t bumpy.

I will be getting a D4, and I will be testing it under water, but we all know about what to expect. Testing boost drivers is more interesting because they can’t all maintain flat output. They do all stay close enough to flat that you wouldn’t notice if you weren’t doing an instrumented test though.

He answered but as I mentioned before it’s better to discuss some questions directly because the key point is always lie in details. I just dont know it all. Fonarevka is opened for everyone :wink:

“The most suitable driver for such purpose based on STM32F050 or something else. It has usb loader, can be coded on C. ADC and PWM works faster and that must be enought for such purposes (there’s no hardware division, C in a few times slower than assembler but microcontroller has advantage on 48Mhz and 32bit). 3V LDO is needed (ACS711 for example), also a normal thermal sensor that does’t requere callibration. The rest scheme part is the same. Thus people could easily develop, flash and configure driver through the usb. The existed scheme is based on AVR, code is unclear and sensitive to edits. Here it is in open access, if someone need it they’re using it as is…”

Personal contact is important. It’s not even necessary to get a licence in some cases. For example, I got a permission to use a non commercial driver firmware in my project that I want to finish this year. So it’s all up to you, hope I’ve assisted a little bit.

Thanks!

I’ve considered using STM32 controllers, but for now even a tiny85 feels huge. Normally I have been using only tiny13 and tiny25, which work pretty well with C. Tiny841 also looks nice, with extra pins and some newer hardware. But if that becomes too small, STM32 is the next step up.

Let me share this here too:

I vote for the middle one.

I don’t think that “50% battery” is a valid comparison. If you arrived at 50%, you used it for X minutes. Weaker flashlight after the same runtime will have more energy left and after long enough X it will surely outshine a DD light.

For me it’s the fourth from the left.
The one with the last step removed. :wink:

Got 3 of your D4’s Hank, spectacular, when are your D1S lights going to be available…? Thanks

T18, do you have a XP-L HI Version of the D4!?
If so, how ‘heavy’ :wink: is the max. lumen output!?

Yes I do and should weight the same as all of them, very little weight difference in the weight of emitters and frankly IMO it’s a bit much for this light, cold to blazing hot in 30 seconds or less so if your just wanting to shock and awe someone well that will do it, but if looking for working light at higher levels this might not be it, sort of depends and I don’t have a box yet to do any OTF testing, I think TK might have specs for that, or soon anyhow as she’s in the groove for furthering development now. Sorry I couldn’t be of more help, just a mention, I also have the Nichia and S4 2B which are cheaper than XP-L HI 3A and more usable so not sure really if I would spend the extra $$$$ again, working on toning it down some, different emitters.

Edit: May have misunderstood your weight/heavy question, ha ha, duh…

Excuse me Sir where is the video? Thanks

Hi Hank,
When will the D1S be ready?

D1, will be coming first which is going to be available in 18650 18500 and 18350
Very small size, throws around 40Kcd.
Probably in the middle of the month towards the end of the month, D1S will follow soon.

What is the difference between D1 and D1S?

D1 is much smaller than D1S, slightly bigger than D4.

Can you perhaps tell us more about the D7? :partying_face:

Emisar D7 uses 7 LEDs and 3*18650 in parallel, it is scheduled after Emisar D1S.

Yes! Yes! Yes! :partying_face:
