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

It’s pretty well documented by me and one or two others that 6V is not a problem for the 7135 chips if the led is dropping most of the voltage. Then all you need is a voltage regulator IC to maintain 3-5V to the Attiny mcu. That done, master/slave works fine. I personally have run up to 12V with 3 series XML this way. For 6V input I would use an LD2981 5V chip like this.

I have no idea what you just said, was that Greek or what? But I am very glad you know how to move those things around and get to where you’re going! :slight_smile:

Gonna have to have another Black Russian after that one….

Easy there, sparky...

In this thread, Rufusbduck does some pretty extensive experimentation with a Nanjg 105c type driver. In post 43, 4th picture down, there is an actual example of what he is talking about above. Please correct me if I’m wrong Rufusbduck.

Well, after a bad session with this light, I have decided to put it on hold. This may be a real Sky Ray, but after what I have seen tonight, it probably is a poor clone. The head to body is a mismatch. If a single reflector is put in the head, it is not centered. It is off center which means when you turn the head, the led hole would look like it is turning in an oval. If you have ever seen an off center reflector, you will understand what I am trying to say. Maybe not the best explanation, but anyhow either the head or body was not cut true. You could never take the head off, without taking the reflector out first. If it were turned off, it would wipe out the led dome. With the stock 3-up, it wouldn't matter, since the reflector and LEDs are stationary to each other, but with a single reflector it shows up big time.

Also the threads are super sloppy and you can almost pull the head right off the body because the threads are so bad. It's fairly depressing to see the lack of quality there and compared to the Fandyfire I had, it's just poorly machined, plain and simple.

I put it up till I figure out if I bother with it or maybe get another fandyfire to use as a host. It's a real shame.

One word, BUGGER.

Yep, I see the same things on the one I just got. The OD of the battery tube o-ring is 1.980", the ID of the o-ring bore in the head is 1.988", it doesn't even touch. Also they've switched to a much thinner lens and make up for it with a super fat o-ring to use as a spacer. The crown bezel is aluminum, instead of stainless.

This isn't about fake-vs.-genuine, as all of them are copies. But I think they've finally crossed that line where the lower price no longer makes the flaws tolerable. Flaws that don't affect the function are one thing, but o-rings that don't actually seal are kinda a deal breaker. Why didn't they just omit the o-rings? They could have saved another .00031 cents per unit.

Anyone know of a source for a better quality BLACK SRK?

Bummer. Sorry to hear about that. Sounds like it would be best to keep the original driver now so that you can easily reconstitute the light in to its original form. Would it be improper for any of us that feel compelled to “opt out” of the giveaway so that you could do that? I hope I don’t offend you by asking this. I am totally asking with the highest respect. You unselfishly give so much to this forum.

Its a shame about the quality.
Old-Lumens and Comfychair, where did you get black SRK come from?
If its from FT, please give them a notice, they seem to care about such matters and will hopefully find a better source.

If color is not an issue. Gold SRK can currently be bought for 32$ from Wallbuys (sale + discount code). I have yet to hear people complain about such matters on them. But you never know…
Thread about the sale here.

Looks great in the pics, unfortunately the one they're shipping is completely different.

CNQG was the original seller of the black SRK and I believe those were very good quality.

I'm not going to bother with Fasttech, since I'm never going to ship it back (costly) and since I have torn it down for modding, they can't really do much. I accepted it initially and tore it down. I should have inspected it better first.

I imagine I will pick it up again sometime and finish it, but I would probably have to center the led with the reflector, mark reflector and head for position and Nitecore the head on the body, so no one can twist it off That way it will look centered, even though it's not. That would mean loading batteries from the tail.

Time for that old song.... "Welcome To My World", Won't you come on in.... can't remember who sang that. But OH HOW TRUE!!!

Dan.

OL you should make a charging jack and leave the batteries in there :slight_smile:

Hah! I was going to post the same then I saw you beat me to it. :slight_smile:

That’s a bluesy song written by Winkler & Hathcock made famous by Jim Reeves in ’62 but I grew up on the Dean Martin version (only singer I know who sings from a sofa) :

RIGHT! I couldn't have told you though. I remember both of these guys singing the song now. THANKS!!! I needed that spot dusted off I guess! Dan.

Some seriously funny folks! Back in the day with Bob Hope and Johnny Carson when everything was shot live. They were always smoking and carrying a drink, on Television. Don’t see that anymore!

Bill Cosby, Flip Wilson and on other fronts Bill Murray, John Balushi, Chevy Chase, Gilda Radner, Harvey Korman and Tim Conway. Who’s world? Certainly a far different one than today!

Can’t believe I even remembered all those names! lol And there’s more, to be sure.

Thanks for the flashback, remember what a flashlight was back then? Oh Lord! But still better than nothing, or so we thought back then. Believe it or not, I have a pair of Eveready “D” cells, paper wrapped, from the 30’s that look to be in perfect condition. Wonder if they still have a charge? lol

OL, I’m stepping into your world a bit with a 3D NiMH Mag conversion. Had to get the Imedion Low Self Discharge cells and found they’re not exactly cheap, running as much and more as many 18650’s. Have an Elektrolumens drop in coming tomorrow with 3 XM-L2’s putting out some 2000 lumens on these cells. Can’t wait!

Best of luck figuring out how to drive this project, will be watching to see how you do it :wink:

Belies our ages too. :stuck_out_tongue: Dun forget the crooner old blue eyes Frank Sinatra of the rat pack and also Jerry Lewis who once teamed up with Dean for the funnies. They wouldn’t be the same with e-cigs today. Some singers nowadays just perform drunk. Looking forward to this SKR mod solution!

It was actually a 101 AK but I also did it with 8 x 7135 on a separate heat sink. The number of chips used is only relavent to the Vf at the drive current so the modded driver should be fine with a 6V led and 5x nimh.
