As the subject really, I have a SkyRay King on order but would prefer 3 modes, are there any drivers that I can buy/modify/build to change the modes?
I have seen some that require the cells in series, maybe 3x single cell drivers would work. I am not too fussed about the electronic switch, I can modify/make that work with any driver.
The physical switch looks to be a standard momentary switch as used in all types of consumer electronics, depending on the driver just add a latching state.
To change mode you have to change the Circuit Board first ,such as this one .And as to choose the circuit board ,you have to know the diameter of your flashlight .Can you tell me your flashlight model?maybe I can help you
I’m currently working on a King driver mod, unfortunately I don’t have much spare time currently… I’ll post results when I’m done (if I succeed, that is), may take some weeks.
Maybe you will want to rethink about the spacing values for the modes: output is not linear with current, with your amperages I feel you will end up with 4 very bright modes, very close to eachother, and no real low.
For example, a light that I like a lot for the spacing between modes and good low, is the Lumapower Dmini-VX, and it has 2,5A - 0,50A - 0,12A - 0,02A
It wouldn’t be a straight up driver swap. The King uses an e-switch that doesn’t rely on power interrupt to turn off or mode flip. So the mode control EPROM of the circuit never really completely powers off. AFIAK no one makes a drop-in replacement driver that uses an e-switch.
Likewise, modding it to 3S or 4S 18650 would require a lot of DIY fabrication too, at both the + and - end. You would have to effectively isolate the cells from the - tailcap end and from the + head, and in place of the “P” connection wire everything up for series cells. Definitely an advanced mod, for a builder with some serious DIY fabrication skills.
Cool… keep us updated on how that goes. You should also kill the low PWM while you are at it. IIRC its in the vicinity of ~100-130 Hz which is way too low for almost everyone.
I am waiting until someone finally find the way to change this stupid modes (hi-lo-strobe) and then I’ll get the King :- )
Hope to insert DrJones’s ramping sw :- )
