I'll get that driver shared on Oshpark soon, just need to clean up a few things. The 12mm will work, but this one is a bit easier to install and put in the pill. I would get a 0.8mm for the Tool so you don't have to file the pill so much!
I think I’ll make a new copper pill for my Cu Tool when I go to upgrade it. Might as well have it all copper. 
Dude, you made this board eon’s ago! Before your little girl was born I’m pretty sure, and she’s what, in her first beauty pageant already? 
You can also apply thermal adhesive to the underside of the pill and solder o couple of 10mm sinkpads together to put there for extra heatsinking…you may even be able to go three deep.
I'll probably just buy the kits pre-flashed with the std 4 modes, if he's got them that way. Think I never bought the MMU's, but did buy the flash board, thinking I'd use it some day...
Ohh - the 10mm boards you have may be too thick? I gotta check sizes then. Maybe it's best to wait til you got them, or I can order them from OSHPark then. Not sure how the filing would work - gotta look at it again. Thanks!
10mm is too small for the tool; you would want the 12mm driver in 0.8mm thickness. I have some 0.8mm 2 oz. copper, I will get them listed too all in one go.
The other driver I have already has the "ears" and fits right in there without any filing. It also has some through-holes that make threading in the pill a snap. Same circuit though. I have a attiny25 version as well, but it still needs some tweaks. It runs OK, but really it needs a 7135 or similar too, so that's also what I'm working on :-) (hard to make that all fit!)
I’ve been chasing these 9mm round XP centering rings for a while but I don’t feel like placing an order on Simon’s store just for them. Would be nice to see them for sale at MTN

Looks like Supfire M6 with mods are back in!
I agree with DB - good post. Thanks.
I was about to ask why this was even a question!? The original “Zener mod” was for the Nanjg-105c (which is an 8x7135 driver) and I don’t recall any failures. DB beat me to it by remembering that he’s got at least one Zener modded driver in that 7+1 config. … but then RMM posts this, very interesting:
RMM, does this apply exclusively to FET+1 / 7+1 configs or have you also seen this on your Zener-modded qlites? IIRC you sold quite a few of those in the past, so I’m very interested in what you’ve seen.
Hank, you fried the emitter while soldering wires to the Noctigon? EG the emitter was already reflowed onto the Noctigon by RMM and died while you added wires? That seems pretty wild to me. Are these emitters more fragile than others? I forget what soldering equipment you use, it might be worthwhile to bring that up.
Hi will34. I have 10 of them from Simon’s. If you want I can send you a couple. I found them very thick for XP-L HI. PM me if you want them.
I have a bunch of them, but they are not very good; the spacers are too thick and are often fairly loose on the LED. For a non-generic spacer I expected more. I will list them with that note.
All sounds good, Thanks! I'll wait til you get it listed, maybe the 25 version. If you fit the regular 25 w/pins, I got plenty of those and some nice custom firmware for it. I like the luxdrv type of short cycle memory, and got a pretty nice version for the 25 w/blinking out the batt voltage, etc.
I just ordered the XPL spacers from BG here earlier this morn. Maybe for the height they can be filed down, but the sloppiness sounds like a problem.
Yes, the zener mod qlites will also overheat badly if you run only 8x7135 chips and good cells (high drain 18650; 26650), but they do fine at 3A with 18350s. With 18650s I would always recommend running at least 12x7135, and 26650 16x7135 if you are planning on running it on high for long. Generally, the chips are not damaged, but the efficiency and output really stinks if you have too much voltage overhead.
Remember, the 7135 are linear voltage regulators, so your power dissipated increases drastically as the difference between vIN and the vF of your emitter @ the set current increases. As you increase the chip count, you not only spread the heat, but you effectively lower the differential between vIN and vF. The batteries will sag more, and vF is higher at a higher current. This is also why smaller batteries can run more efficiently at lower currents (they sag more under load).
With a single 7135, the vIN + vF delta is is very big for a 2S emitter, and there is only a single 7135 to take the heat. It seems like even the 7135's internal throttling is not enough to save the chip from damage in this scenario.
Lol, are you kidding? That won't come close to fitting! We're talking about the MU version, which is still significantly larger than the MMU.
Fair enough, and in fact I think I recall you making that specific recommendation (going from 8x to 12x or more for MT-G2 applications).
I’m a little surprised that 1x7135’s internal protection couldn’t quite handle it, but there must be a limit to everything. Thanks for the info.
When using the tiny25 you could gain some room by losing the two voltage divider resistors. Attiny25/45/85 can measure battery voltage without them. See my post here: Flashlight Firmware Repository - #790 by Halo
Yes, but it isn't as precise, and ToyKeeper would be very upset with me if I reduced the voltage readout accuracy!!! 
I can make it fit. 0402 aren't that small.
ToyKeeper commented that there should still be enough accuracy since we have resolution to spare currently.
I was think'n (maybe dreaming?) the 12mm board would have all this extra space over a 10mm board, hhhmmm, well a little more? 
On anything smaller than a 15mm board an SO8 MCU isn’t very practical for single-sided applications. Take a look at my 10mm/12mm/15mm “DD-L” drivers for comparison if you like.
Well this was good timing for me to read this thread. I just pulled apart my Cu Tool to begin modding it with a 12mm FET driver. But with a purpose built one being released I will save this driver for something else.
Richard, this has probably been answered plenty of times before, but can an XHP35 be run on a FET driver from a 3S carrier?
