Custom SkyRay King SRK Driver

I joined up specifically because of this thread. I have been “collecting” lights for a while and have a SRK that I was going to program my own driver for. This beats what I was going to do hands down. I would just like to say congratulations to texaspyro for the work so far and to also say I will purchase 3 boards when they are ready. I have no problems with SMD soldering, electronics in general or microprocessor programming so if texaspyro is after a guinea pig for any beta testing I happily put my hand up, just ask.

Once again thanks texaspyro

I bow and salute you Sir TexasPyro,
Your effort and dedication to the cause has not gone unnoticed, I will be glad to put some extra moolah your way when ready,

Any updates TexasPyro? I got a kung I want to try this driver in. This driver would be alot easier than wiring up 4 2800ma amc7135 drivers in there.

I made some tweaks to the board layout to make it easier to add a slave driver. Waiting on the prototype boards to come in…

I’m definitely in for one!
I managed to toast one of the REGs when I disassembled (wire came loose, shorted the REG…).

I love what you are doing with this driver! The parasitic is awesome and the modes are as well.

However: is it possible to program this ourselves?
I ’d really like a simple high/med/low/off or High/low/moon/off for regular use and then a Moon/strobe/SOS/ramp/etc etc for a second group.

You can program the modes that you want to use (in the order that you want to use them) along with several other options. Think of the default mode list as a menu of available modes (there’s a LOT of them). You enter programming mode by holding the button down while applying power to the light. Click to the first mode that you want to use and hold down the button for one second and that mode is stored. Lather, rinse, repeat…

The firmware does not support mode groups, though.

OK, so I can program it on the UI! That’s sweet!

I was thinking of hooking it up to a computer to reprogram, but this is even better!
With this it’s possible to change the programming on the fly!

Awesome!

PS: now I’m in for TWO driver boards! :slight_smile:

I’m really hoping its up for release soon. I don’t really want to wire up 4 amc7135’s drivers in there. If I did I would want to wire them individually to each led. I was hoping you would save me from all that wiring. :bigsmile:

Do we need to get on a list? Pay in advance? Learn a secret handshake?
If I receive my two M6’s I’ll need pair of these.
Looking forward to moding my first flashlight.

TexasPyro, you should sell the lights with driver installed as a unit too: I know a few who would buy already.

I’d be all over that like a hobo on a ham sammich!

me too

Great job on the driver, count me in for 2 please. I joined particularly because of this thread, I’ve been buying lights for a couple months now and always come to BLF for reviews and recommendations. Once I saw this thread last week I had to get myself an SRK, actually I got a FandyFire UV-S5 from FT. I couldn’t be happier with the quality, the anodizing was perfect LED’s are centered, even has the 3 toroid driver, no PWM noise on low. I’m going to buy another when you make these available so I can mod both and have some back up drivers, you know, for the zombie apocalypse.

tp, do you think there would be any issues with tying all 3 channels together to run a single parallel array?

For the few that don't mind adding their own components, are you selling the bare circuit board yet?

Should work fine…

Im curious about this too.

I’ve been looking for a driver board for my skyray king that came from china D.o.a
Dead on arrival searching for the last two days for driver and came across this website awesome
I don’t know a lot about Cree torchs but from reading the comments i will take 2 completed boards

guys could someone pm me where I can get a driver board that fits the sky ray king
Until these boards come available

Welcome to the forum F137.

Maybe someone here will have one and contact you. In the mean time, you could email some of the big discount vendors such as Walbuys, Fasttech, etc. I'm sure they can get you one. Hopefully, at a low price.

If you're handy, you could fabricate a battery board out of that through-hole type of hobby board. Use copper tape or solder copper sheet where the battery and body make contact with it. On the other side, hook up a driver or drivers that use an electronic switch.

EDIT: Or if you know how to wire 7135's directly, you could replace the momentary switch with an on-off type switch. Then wire the right prong of the 7135's to the switch and the switch to positive on the batter board. The back tabs of the 7135's could be soldered around the paremiter of the battery board for negative. The left prong of the 7135's would feed the negative of the LED's. The positive of the LED's wired directly to the positive of the battery board. You will only have one level of brightness, but at least your light would be working.

Maybe he could open a new thread to get hints to repair his stock driver…
I guess if its DOA it’s just a connection problem somewhere…
