Driver problem — I’ve just installed a 5×7135 driver (bought months ago) set up with Guppydrv
but it’s got next mode memory on all of its settings.

Any guess what I’ve done wrong here? Could I have grounded something with the retaining ring?

It’s running a PC amber emitter that also came from Mtn.

Oh, and the turbo timer drops down to moonlight, not to 50 percent.

Is there a way to cancel the turbo timer completely?

EDIT nevermind, found how to cancel turbo timer by setting to 4 seconds or less (info is on the page for the larger diameter driver)

And I found a thread about the next mode memory problem at: http://budgetlightforum.com/comment/1159984

Hi, RMM. Any idea when you might have Shockli 5500 mAh 26650’s back in stock? Thanks…

Richard is now selling e-switch drivers with the Emisar D4 UI v2.

It’s available now on his website in various sizes from 15mm on up.

This is great news for all modders who love the v2 firmware in the D4 and want to put it in their other e-switch lights.

If turbo timer is stepping down to anything less than 50% there is a problem.  To go any lower than 50% the driver thinks the input voltage is low.

Richard, is this the same driver that came with the D4 v1? I have a v1 and I’d like to change to v2 if possible. I don’t mind getting the same driver with v2 firmware and replace it.

No.  It is the MTN driver with the same firmware, not the D4 driver.  You'd be better off just reflashing the existing driver.

Regarding the MTN Quad and Emisar D4 flashlight:

You can swap the MCPCBs directly, with NO SPACER required.  I had read some comments stating that a spacer is necessary, but doing the measurements and actually building some lights with the MTN Quad MCPCB it works fine without any extra spacer needed.

Could I put 4 XP-E2 Green emitters on your board and run em on the FET or would I have to reduce direct drive through PWM to keep from smoking the emitters like I did the Lee Filter I tried?

Maybe use the 18350 tube and a lesser cell to keep max current in check?

The ‘next mode memory’ problem I have is probably a bad capacitor or two, as people described here:

It can't be the capacitor.  Maybe we flashed it with the wrong firmware or something because there is not OTC on that 15mm 7135 board, so the capacitor will not affect the memory.

It is a firmware option for the FET+7135 drivers---not a completely separate driver.

Bummer, I need a couple of side e-switch drivers and had hope for a good driver with good firmware to replace a couple of factory drivers.

Did I say 15? It’s 17mm

And they are available. Just select the correct diameter of driver from the list of FET+7135 drivers, then use the dropdown menu to select D4 v2 UI.

Hi Richard, what turbo timer option should I choose on the 17mm fet +1 driver with the D4 firmware? I wish to have the same configurable temperature step down as the D4.

Thanks

I don’t think the D4 ui has a turbo stepdown, so you can just ignore that menu. At least that’s what I did with my order.

Just ignore it.  It is going to be the same firmware regardless of what you select, like Bistro/guppydrv/moppydrv/Crescendo.

I just received my first order from MTN and I am just really impressed with the quality of that L2 host. To be honest I bought the scratch and dent version and I don’t think anyone would know if I had said it was one of the first quality lights. I had to look at it for a bit and finally found 1 scratch on one of the fins on the head. The only thing I would suggest is throw in a couple screws to screw down the MCPCB with. But if that is all I have to worry about we are all good. Thanks a lot!

My apologies the screws had just really gotten hidden in the package. along with 2 centering rings and an extra spring. Thank you.

Sorry of this has been asked (for the next D4 tranche)

ETA?

Has anyone offered to do any flashing of the first batch of D4’s..?
I bought 3 of the 1st batch and not quit up to flashing skill level so just wondering if there’s been any offers, can pay cash for flash or barter..?

We will reflash them if you pay shipping.  Flashing is easy, getting the driver out without breaking anything can be difficult. Are you sure that you got the first firmware?  We only sent out a handful of lights with V1 firmware.  Quite a few with what I would consider to be V1.9 firmware (newer thermal throttling, but for more uses it is as good as V2.  If it blinks in the middle of the ramp then you do not have V1 firmware.

Hey Richard – any chance of getting a S2+ host in Desert Tan? I know you haven’t even gotten the fully built tan ones in yet, but figured I’d ask if there was any plan for a host-only version too. I need a tan triple…

Yes.  We have both tan and clear S2+ hosts on order.

Nice! I was thinking of ordering an 18350 tube in desert tan and grab some Aspire cells. I’ll be patient and get them from you when they arrive.

I may send my D4 to be re-flashed and then you can send them back all at once.

Now what else can I buy?

Main difference I’ve noticed between V1.9 and V2.0 is that V1.9 has some bugs.

With my V1.9 light, I’ll start off in moonlight and after a second it will occasionally jump to max turbo…. not good if you happen to be staring into the emitters admiring the pretty tint. Don’t ask me how I know…. Evil

I’ve also noticed that sometimes my V1.9 light will start in moonlight and then step up to a low brightness on its own even when not being touched.

In all other respects it functions just like V2.0. However, V2.0 is better because it has no bugs.
