I’m not sure BLF is the right place to find sensible people. :slight_smile:

I built a triple-XP-G2 a few days ago from RMM’s parts, and it was fairly easy. I went with a red Convoy S2+ because it’s pretty and has a nice metal button, but the pill is the wrong size to use with RMM’s spacer (I had to swap the pill with an older S2). Aside from that, I used a FET+1 driver because I wanted maximum turbo plus sane / efficient low modes. However, I do not recommend using a FET in these unless you give it a short turbo step-down and are careful about heat and make sure all the thermal interfaces inside the light are clean, flat, and properly thermal-pasted.

On mine, the maximum output is 2250 lumens… but I gave it a 2-level turbo step-down with only a 15-second timer, so it drops to 1050 lm then 425 lm in 30 seconds.

In general, I’d suggest following the recommendations RMM made on the S3 triple, under “Power Level”… instead of doing what I did and running it at twice the maximum power level he sells.

Does he really have to answer that?In my house and I’m sure many others, the answer is clear!

The answer is Ever Clear

What fun is sensible?

I just finished machining a spacer for my little triple. Is that firmware version in your repository? I’ve got a MTN - 17DDm and XP-L’s so I just might need a short turbo timer.

Hi Richard… This is really interesting… do you maybe have more information?

Thanks MRsDNF :wink:

Richard, I may have missed comments about this… How do you experience the gains in the XML U4 vs U3? I presume you have not done some testing yet?

Yes, but it’s a bit complex… it’s under ToyKeeper/blf-a6/cypreus2 if you want to try it, but I made it mostly for my own personal use. It’s kind of a kitchen sink type of build.

I won't know until I actually build some lights with them---several to be sure. Djozz will probably get around to testing them so we can have a more direct comparison. Right now all I can say is that they are at least as good as the best U3s.

I have a 9 emitter showerhead light in need of emitters, and I have, as it so happens, 10 of these new U4’s on the way. Hmmm…

moppydrv: a guppydrv like firmware for momentary switches, by our fellow forum member DrJones.

Want to suggest some mode groups for a second revision? Submit yours here.

moppydrv Multi-Group Electronic Switch Firmware Option

This firmware allows the ultimate in user customizability, with 16 built-in mode groups, that the user can select via a series of button presses and a user programmable turbo timer that will automatically step the power down to 50% after the set time is hit (see below for instructions).

Low voltage protection: With 2S cells the light will begin to step down output at around 6V under load. The light will not shut completely off, but will continue to run at a moonlight level.

  • 3S cell drivers currently have no low voltage protection with moppydrv. If you want low voltage rampdown with 3S cells on the input please choose one of the standard or custom firmware options.

User Selectable Groups:

MAIN GROUPS | [SPECIAL/DOUBLE CLICK ACCESS MODE]

  1. 100% Only
  2. 5% - 100% | [100%]
  3. 30% - 100% | [100%]
  4. 70% - 100% | [100%]
  5. 50% - 10% | [100%]

moppydrv Instructions

Operation:

  • A short tap switches the light on to the previously used mode, or off if the light is already on.
  • A press & hold while the light is on cycles through the modes in the selected mode group.
    • A press & hold while the light is off switches the light on in the first mode of the selected group.
  • A double-click from either off or on puts the light into the special designated mode in that particular mode group.

To switch mode groups: rapidly tap the switch 8 times from either off or on. The light will then enter the programming mode and begin to flash, reading out the battery charge state. With the light in programming mode, tap the switch the same number of times as your desired mode group. The light will blink and your mode group will be memorized.

Example: To select mode group 3, tap the switch 8 times quickly to enter programming mode. When the light enters programming mode and beings flashing, tap the switch three times. The light will blink to recognize the mode group change.

To set the turbo timer: rapidly tap the switch 8 times. The light will then enter the programming mode and begin to flash. With the light in programming mode, tap the switch 20 times to enter the turbo timer set mode. The light will then switch to 100% power. When the light is at the desired temperature for the turbo step down, turn the light off. The turbo timer will then be set. The turbo timer steps the light down to 50% regardless of the mode group set. To disable the turbo timer, simply set the time to under 4 seconds.

This looks like a great momentary UI. Mode memory plus instant access to moon/turbo/strobe.

Thanks RMM and DrJones

Hey RMM,

When do you expect your shipment of Meteors to arrive?

I’m thinking I will go for the grey 1D dedomed, but am curious if it would be faster to wait for your shipment or order direct from Internional Outdoors.

Should be about 2 weeks. I was told that there is a wait time for them to be built (especially the dedomed ones). If someone ordered one now and they arrived before mine, I would be surprised (and a little upset) because I have already paid for mine.

I want one but am still trying to decide between an XPG with a dome, or not. It would be nice to have one of these to play with at the cabin during the Memorial day weekend! :wink:

I guess I’ll wait until your stock comes in then. I want it as soon as possible now that I’ve decided which one to get. :bigsmile:

Just curious… how many grey 1D dedomed Meteors did you order? (hopefully a lot!!!)

Plenty (about 25). I ordered a lot of those since it would be my personal choice, and is the one that I'm most likely to recommend for an all-around light.

Guess that makes the choice then.Can we pure-order to get first dibs? 0:)

I just assembled the green LED on 20mm Noc into the C8 host, driving it with a 6-chip Nanjg 105C driver @ 2.1A, and…. just wow. I can’t believe how far it throws and how bright it is.

Can’t wait to see how it works with the XR-E reflector. I may even try an OP reflector just for the hell of it. My guess is that it will be a nice smooth beam, and still throw plenty far.
