The Sky-Ray King Thrower Mod........ It's Finished! Beam shots are up

I use those reflectors in Maglites. It comes from CNQG. CNQG has one shallow and one deep. I have used them both many times. They will give a decent spot and basically they both throw. It’s more the diameter than the depth anyhow. It won’t be a super thrower pinpoint spot, but it will be more concentrated than a stock king. Of course, it won’t be as bright as a stock king, since it’s one led versus 3 leds, but that’s not the point anyhow. The point is just to be different, that’s all.

The OP is updated and I have a dilemma, which I have described in the OP.

I also ordered size A NiMHs from all-battery, so I am comitted to doing 4xA sized NiMH in series here.

Wait... how do you run a single 6v LED off two 105Cs?

An MT-G SRK would kick butt as an all-arounder! I don’t know if there are any tricks that will let you use one with AMC7135 drivers, though. You’d also need a boost driver if you’re committed to 4*NiMH, and a pretty BA one at that.

Sounds even more interesting. Where are you getting your raw mgt2 emitters? Please tell.

OL my vote is for the MTG2 :slight_smile:

i missed out on buying the caveman haha.

Master/slave and in parallel.

I’m not seeing how you can get 6v out of a nanjg and 4 nimh? seems to me your 1.2v short before driver losses.

Despite feeling xm-l tedium, my vote is for an xm-l and my gut reaction is xp-g2 3d tbh….

It’s just removed from a star. The leds came from cutter, sent to me by an AU member, who shall remain nameless, unless he wishes to name himself.Wink

I’d rather see the mtg-2/reflector in a d sized mag that can give an easy 8.4v, much simpler driver options I feel. :bigsmile:

Per another knowledgeable member:

Two AMC Drivers in Master/Slave

One one AMC Driver, you’d have to remove the SO-8 Chip (ATTINY13A).

Both AMC Board BAT+ connected to BAT+
Both AMC Board BAT- connected to BAT-
Solder wire from a VDD Pin of an AMC7135 of the Master board to a VDD Pin of the Slave board
LED+ to BAT+ or to Both AMC Board LED+ Connections
LED- to LED- on both Master and Slave board.

Edit, I put up incorrect information on this. This would only increase the amperage.

I'm sure not everyone saw the thread but Intl-Outdoor will soon be stocking the MT-G2s and their house-brand copper MCPCBs for them as well.

Man, that just gave me an idea. Couldn’t two drivers be run in series off the batteries to half the voltage to each. Example: Positive from battery to first driver’s positive, negative from first driver to positive of second driver, and negative from second driver to battery negative. Then parallel the drivers to the LED with one being a master.

That would give you double the current, but not the voltage needed to make it light up. Unless there's some other trick involved I'm not aware of.

You'd have to have a supply voltage higher than the LED's Vf, and a way to keep the MCU from frying at that higher voltage (which is possible), but you ain't gonna get there with only four NiMH.

comfychair’s response to another post also answered mine. Serial drivers would not provide enough voltage. Like above, the current would double, but not the voltage. So, while the drivers would not fry, the emitter would not light up.

The output to the LED is parallel. led+ and led+ together, to the led. led- and led- together to the led. This gives you twice the voltage. It's a parallel circuit to the led. It's just like two batteries in parallel. + to + and - to - gives you parallel, that increases the voltage. Series is + to - and increases the amperage. Actually this set-up increases both, as it really is series parallel. The removal of the slave controller and the wire from master VDD to slave VDD on the 7135 circuit produces control to all 7135 chips.

Am I missing something here? I don't think so, but I could be wrong, (like just about every day).

EDIT: Yes, I am wrong. Completely wrong and worst of all I still don't get it.

I believe parallel loads doubles the current, but the voltage stays the same (excluding battery sag).

Serial batteries doubles the voltage. Serial loads split the voltage but the current stays the same.

EDIT: Where are you getting your bare mgt2 emitters?

EDIT2: Opps. Thank you for the answer above. I’m a dumb a.

Nope, that's backwards. Parallel doubles the amperage, series doubles the voltage, and down to the way 7135s regulate only on the negative path you can't connect them in series. Too bad they don't work like DC power supplies, huh?

You'll have to have either the supply voltage above the LED's Vf (2s2p lithiums at 8.4v) (and then, either use a buck driver, or use a work-around to keep the 105C's MCU alive at the higher voltage and try to get the 7135s to burn off the excess ~2.5v), OR, use a boost driver if you stick with 4s NiMH.

Nope. that’s bass ackwards…

Well, that is ass backwards. Makes me feel like the fool that I am. I feel like slinking away after this bit of stupidity.Embarassed My apologies for not knowing my arse from a …
