i recieved my TK35 clone from DX right in time for christmas and i just fell in love with it. great UI and just great size for what it has inside.
The only thing what kinda disappointed me was the output.
it had a XM-L T6 in it and only ran at 2A so i instantly went into modding mode.
Lucky for me my IOS order arrived the same day, i ordered a MT-G2 on copper.
(damn that MT-G2 is big!! first time i bought one)
i turned the TK35 into a TK35UE.
i had to opened up the reflector to fit the big led. That was an easy task. i taped the inside of the reflector with some electrical tape to avoid scratches.
i took a triangular file and just turned it around and the reflector was almost good to go.
i just needed to to some cleaning up.
the cleaning of the hole was not as easy as planned as some metal pieces bent while filing into the reflector. this had to be cleaned out very carefully.
after the reflector it was the drivers turn. i was not sure if the stock driver could run the MT-G2. i searched the forum but could not find anything that made sure it would.
i just thought i would try it and yep lucky me! the stock driver does run the MT-G2!
i ran an Amp test on the stock modes with a MT-G2 and got the following results:
(amps taken at the LED)
L-L : 0.06A
Low: 0.20A
Med: 0.98A
High: 2.25A
after replacing all the wires between the double boarded driver and jumping the sence resistors i got:
L-L : 0.16A
Low: 0.35A
Med: 1.60A
High: 3.40A
this puts it at +-2000Lumen all losses included. 8)
changed the wires between the 2 board to bigger wires
better view on jumped resistors.
not sure if it helped much but it was fun doing and copper never hurts.
i really happy with how the mod turned out.

im sorry for the crappy quality, i took them with my phone.

Low-Low
Low, compared to modded TR-J19 3A per LED
Med, compared to modded TR-J19 3A per LED
High, compared to modded TR-J19 3A per LED
ofcourse the TR-J19 is brighter and the throw on that light is amazing, but i love how the modded new-117 is just more user friendly with its small design and still puts out a crazy amount of light.

I did the same with mine. Changing to MT-G2 emitter, it is easier to mod TK35 clone than ZY-T08, since batteries are already on series. One needs only to open up the reflector and bypass the sense resistor, in order to bump up the current, while reusing the same stock driver. The harder part is now to source one! DX has seemed to have run out of its stock.
I don’t think I had an original idea. Now the question is, are there enough of us to approach a vendor or maybe even the MFG? to get a deal?
Also I wonder how far we can easily bump the current so that the second step down is also more then the factory unit. As I remember the “TK35UE” is only 750 Lumens on the second step down.

it sure is a flooder but it does throw a little, pure because of the amount of light. ill take some picture tonight!
i have a ZY-T08 too and its a pain in the butt to get the reflector as deep over the led as i want it. this mod was just so fast and easy. i was lucky, but only the black one was in stock al the colored (and cheaper) lights were out. u can find some hosts under the UF-F10 name.

Is this the New-117? Is the PWM of this light really as bad as many had commented on? I am thinking of getting one too to mod with MTG2
the PWM on low and Low-Low is bad indeed, it does not bother me that much but if you hate PWM you will hate the stock driver on the low settings. im planning on switching the uC out with a custom programmed one (so i can have ramping but still use the rest of the driver), this way i can also use higher PWM speed.

My New-117 was forgotten because of a faulty switch. After seeing your post I replaced the switch and changed the emitter to a XP-G2 on noctigon. I’m not super sensitive to PWM, but I can see it on the lowest setting on a white wall up close.
Anyways, great mod you have there!
dentillozie,
Thank you for posting this. I think this clone will have a new life of its own now that folks are looking for 2S 18650 hosts to install MT-G2 emitters in.
Now my question(s), I noticed that you are the first one I have seen to by-pass the resistor on other then on Direct Drive, Driver circuits. Everyone else seems to “double”/stack another resistor on top that leaves some resistance in the circuit.
As you can tell I am not an expert but I am working hard to come up to speed.
Oh do you know of any options where we can address the less then desirable PWM this circuit has? you mentioned “switching the uC out with a custom programmed one” do you have a microcontroller in mind?
Thank you in advance
Kevin

The stock light uses a buck circuit to bring 2s voltage (6.0v to 8.4v) down to 1*XM-L or 1*XM-L2 voltage (~3.0v to 4.0v range). With the higher voltage MT-G2 there is very little headroom for the buck circuit to operate in.
Still fine, still on a break. One day I’ll catch up with you folks! previous wight catchup

Wight,
Thank you for help.
I read “Understanding the difference between Linear, Buck, Boost and Direct Drive drivers” at http://budgetlightforum.com/node/33820
And I think I follow most of it. but I think the new MT-G2 and XHP emitters are all exceptions to his conclusions about design number limitations do to the higher needed voltage.
I looked up “17mm & 20/26/27mm single-sided DD/FET driver release: A17DD-SO8 / A20DD-SO8 / etc” at http://budgetlightforum.com/node/35507?page=8 regarding the “BLF17DD V1.0”
And “BLF17DD Info Thread – Reference” at http://budgetlightforum.com/node/32186?page=5 and frankly I am more then a bit lost.
I know that old-lumens took a tk35 clone and stripped the boards and made it 2p and put new stuff on the board but that kind of work is above my skill set. I liked this host better because unlike the Small Sun zy-t08 this host is already 2S.
I can solder a jump wire or resistor onto a board (I know big deal
. I know that the TK35 Clone is a very different size and configuration then say the typical C8. so how do I get one your recommended drivers screwed into the TK35 clone? each of the two boards is screwed on with four screws. Do they come in this configuration?
From one of the postings I saw you have had your challenges upgrading wiring. If the design goal was to push “HI” to 4-6 Amp range I think (but am not sure) that 22 gauge silicon as shown in the post above should be sufficient. What do you think?
My understanding is that some work has been done to develop a good 6V Driver but I do not know if the design has a consensus yet or if it is available in a screw in configuration for this host, that to me just screams for a MT-G2 emitter to make a very usable all around light.
ANY help is appreciated.

Ronin42,
I like New117 because it is relatively compact for 2×18650 host and it is already 2s (no need for ugly hack, eg:ZY-T08).
If I were you, I would start something simple like bridging/jumping the current sense resistor and upgrading wires to the emitter to thicker ones, while still using the stock driver.
Those are what I did. I plan to completely to change the driver someday in the future, if I have the time and grow bored of it. But at this present moment, I find that I’m quite okay with the stock driver UI and the brightness (I can get up to 4A driving MT-G2 with a good pair of batteries).
Just give it a try, and later decide whether next you are going to replace the driver, or not. Aside from the MT-G2 emitter, it almost costs you nothing (eg: only wires vs new driver).
This may call for a slightly deeper understanding of how things work.
DD is what you can get away with whenever input and output voltages are close enough to settle down into a….. now where did I already go on about all that? hmmm… . .OK, take a look at my posts in this thread (Note that I made a typo as Bright_Mike points out, this has now been struck through. Focus on posts #9 through 23): http://budgetlightforum.com/node/35657#comment-680541
Also take a look at my posts in this thread (Note that DD ‘drivers’ are NOT part of the discussion. Later in the thread when I say “LED drivers are all constant current” what I really mean is that generally nobody is selling Constant Voltage LED drivers. Focus on posts #7 through 18.): http://budgetlightforum.com/node/1052#comment-678822
Report back on your findings of course.
Can you link to whatever you are looking at with me & wiring? I’m sure I have plenty of difficulties, but I don’t remember whatever you are referring to. (24AWG can be OK for 6A, depending on other factors. You’ll probably have a better handle on it after scrutinizing the graphs I refer to in those threads.)
Now, as to how you’d fit an AxxDD-SO8 driver… they are very small drivers. You’d just bypass the stock driver and put the new driver in the middle of the sandwich. No problem: PLENTY of space in there.

(“It’s good that most people can’t remember their previous lives. Otherwise

Ajaan Lee Dhammadharo)
wight,
I have read both links provided -done
Regarding wiring I did not intend it to sound like a dig, I simply saw a bit about 18g wire that you and cereal killer discussed. As far as what I am looking at, it is the 3rd photo of this post (don’t want that to sound like a smarta**)
My plan is to buy some 22g or maybe 24g if you say that is not beyond the point of diminishing returns for the mods to this clone, if that’s a bad call let me know.
The AxxDD-SO8 sounds like a good easy solution. do I need to strip out components from the existing boards? or does it really just fit in there?
I know enough to know I don’t want to learn how to design PCB’s, I know that the folks here who do the designing have forgotten more then I will every know.
With that said my gut still tells me “we” should have a MT-G2 emitter (“bolts in”) driver for this light. it just deserves it!
Oh and this thread “17mm++ single-sided / DD driver w/ low parasitic drain for e-switch lights: AxxDD-SO8+LDO” started by a very smart guy at http://budgetlightforum.com/node/36023 seems to make a good case for a design with no zener diode in it, although this TK35 clone is clearly a clicky light (aka mechanical switch) and as the thread says thus parasitic drag is a non issue, but the moonlight mode argument is a good point.
Yes I can see you were the thread OP.
maybe you are just the guy to come up with a PCB’s / Driver for this itching MT-G2 platform?
(“It’s good that most people can’t remember their previous lives. Otherwise
things would be a lot more complicated than they already are.”
Ajaan Lee Dhammadharo)
After reading both threads you probably see how DD works: between battery voltage sagging and LED current being tightly tied to current, cell performance dictates maximum drive current…. assuming your DD driver is good (Like A17DD-SO8 or BLF17DD, which is just as good.) The performance of the stock driver with resistors bypassed is limited by the baby FET and the inductor (coil).
I did not take the wiring comment as a dig, don’t worry. I often need clarification when people mention things. 18AWG is only for extreme mods. 22AWG will be fine for your purposes I think.
The A17DD-SO8 is very small. Take a look at the pictures in the OP of the driver thread. I’m sure there are more pictures deeper in the thread, but those should suffice. If I was putting it in the stock light I’d strip the bottom PCB. I don’t think the top PCB needs to be stripped. All you really need to get to the new driver is BAT+, GND, and SW+. All you really need to get to the top/contact PCB is LED- and BAT+.
Unless supply shows up again there doesn’t seem to be much point in making a new driver for an unavailable light.

The lights are available, It is not like they are out of production (yes the names on model numbers keep changing but it is the same tooling). As single cell lights have been the big mover it has lost is appeal from 2011 or when the tk35 came out. But now with folks showing a growing interest in 2S, MT-G2 mods I bet this will be ever more available as “they” see market demand.
To some degree the TK35 UE and the new Nitecore P36 are cases in point of new supply for similar 2S MT-G2 lights.

Dealsmachine has them, ordered one a few days back. Shipping was 3$ or so.
wight,
I have also found that they can be also listed under the following model numbers:
Small Sun ZY-T92
New-117
117
Unique Fire UF-F10B
UniqueFire UF-F10
S020017
RD-777
W777
and some times “mislabeled” as Fenix TK35
I think in my search I found the “current” mfg but I am not sure? The distributor I bought mine from I know is operating under two different names.
I think if the Mfg was smart they would release their own “TK35UE” for the market but maybe they need some help? Which might be one of the benefits of a forum like BLF. So maybe both our community and the Mfg can benefit from each other.
I was also thinking that it sounds like you could whip out a board design pretty fast because as I understand it, it is not really a design challenge other then laying a “smaller” design on a larger board that has the holes for the screws and wires added in the right place. Yes I am sure I have over simplified it, but 3-5 brightness modes or if strobe or sos flickers first does not seem to me a deal breaker. But having the ability to open it up, solder bigger wires coming of the batteries and then screw in the new boards and solder the needed wires in place could put this on the short list of desirable hosts to mod or for a “new new 117” to be built on.
To me one of the questions is, “Is the MT-G2 emitter usage in growth phase or has it peaked and has matured and is now on the decline phase of the its life cycle. for use in Flashlights?”
Or maybe I have flashaholism? and I am not able to make rational decisions?

this is correct, if i would try and hook up a XM-L (3V vf) the LED would go poof. i went with shorting out the sense resistors just because it was easy and fast. it gave me the exact output i wanted as this light does not have a great amout of heatsinking and would get to hot if it would run on high for a longer time. i am still looking for a propper ramping firmware, so if anyone knows one feel free to PM me.
as im having finals i have not found any time to take some beamshot. as soon as i can (and if i dont forget) ill take some and post them here, but there is no real hot spot when using this light outside. but because of the amount of light it can still throw 200 – 250meters

“I just did a new-117 for a guy here and really liked it, I’ve got another I’ll be doing for myself when I have time.
I used the factory driver but stripped off the MCU and used a 10F322 air wired on with UFLC which works really well with this switch setup (also resistor modded it for the desired output). It’s a pretty damn good driver once you get rid of the horrid PWM rate, seems to remain in regulation down to about 3.85v (per cell) from what I was able to see.”
I am sure that makes sense to you, I have no idea what a 10F322 or a UFLC does

The bottom PCB probably needs at least one component removed for any driver replacement and a custom driver would still need to be assembled.. so it’s really on great advantage.
As far as the MT-G2 peaking… who cares? High voltage definitely isn’t peaking, so we’ll continue to see emitters which need at least 2s just to DD.
Thanks tryps! I always recommend a sense resistor mod rather than a sense resistor bypass. If you aren’t comfortable with higher currents in that host (fair enough) then you won’t be able to drop high drain cells into the light as you have it built now. With a resistor mod you could. A resistor mod would also allow you to use 4*CR123A in a pinch, not that most of us are commonly in the sort of pinch where we have access to CR123A’s, but still. OTOH you’d be forced to settle with a somewhat lower maximum drive current with the resistor mod.As far as ramping firmwares, take a look at what ToyKeeper and comfychair were working on over in comfychair’s Roche F6 hacking thread.
dentillozie is right. Not very interesting to me, the barrier for entry with PIC is slightly too high and I’m already setup for Atmel (ATtiny / Atmega). UFLC has plenty of great functionality but runs only on PIC of course…The Roche F6 is also a dual-switch light, but I don’t recall whether these firmwares included memory or what.The firmware calledFerrero_Rocheror maybe “Ramping_UI_table.c”? in ToyKeeper’s repository is probably what you want (it has ramping and other features). I think the development conversation continued elsewhere.EDIT: struck incorrect text.

Just looked my order up out of curiosity, it was 22,26$+3ish$ shipping. Ordered 12-30-14 and shipped today.
So they raised the price somehow.
Couldn’t help but notice that the Roche F6 is not a dual-switch light. It’s electronic switch only.
EE F35 is dual switch but single cell. Convoy L4 is dual switch and 8,4V capable. It’s driver (LD34) might work a treat but I don’t know if it fits physicaly.
I think JonnyC’s FW is dual switch capabale isn’t it. That way we would have to get an attiny to work and control the CC buck circuit. (IMO zener or voltage regulator is nessesery, air wireing and most likely a breakout board would be mandetory)
I don’t know if CerealKiller is reading but it might be a lot easier if he’d make a small post/writeup and even better if he would sell some small amout of pre programmed PICs if they work good. All that would require him to spend quiet some time and is not taken for granted, he might have a full schedule.
Good point on the F6! My mistake, I’ve edited to strike the text.
JonnyC did write a dual switch version of STAR, but it does not receive regular updates. I’m sure it’s quite far behind the other versions on both features and testing. (It also doesn’t have ramping!) The primary differences between dual switch firmwares and regular momentary firmwares is that dual switch versions do not have an “off” level and dual-switch can have memory. Nothing huge really.
As far as actually wiring in the ATtiny13A, yes it’s easy… a Zener is already present, so there’s probably no need to add one. Using a Nanjg-105c or other PCB as a breakout is recommended for simplicity, but whatever.
CK hasn’t been on much, I take it that he’s busy with IRL stuff right now. UFLC isn’t CK’s though, it’s tterev3’s firmware. tterev3 is willing to program PICs as a service, I’m not sure what the best way to get in touch is… maybe PM? http://budgetlightforum.com/node/30556

Glad to see you know everything about me and can answer for me….
No I’m not on much but it’s cause I’m just to busy (and also I’m not to happy with the direction the forums have gone recently), I’m still building light’s daily and still doing driver’s, infact BU_CK is up and running (in a 22mm size driver) and has been shipping out in multi-cell lights for the last few weeks now!
Now back to this topic, I did one of these with UFLC and an MT-G2 a while ago (as in several months ago), great light for it with both switches at the rear (meaning the power switch act’s for momentary use then you get the rest of the functions with the mode button). I did it by swapping my 10F322 onto the stock driver (of course resistor modded) tho if I were to do another I’d just stick a BU_CK in it and be done. If someone is interested in getting some pre-programmed PIC’s from me just drop me a line. I’m about 4-5 weeks backed up right now on turn-key light’s but I can program bare PIC’s and drop them in the mail without the wait if someone need’s a few. Just EMAIL me
