Fireflies ROT66 Flashlight

About the only way to turn them off, as in no parasitic drain at all, is to not connect the wires. I would check that there is voltage going to the potentiometer. If so, then it should be simple to just turn all the pots until the leds start glowing.

After turning they won’t turn on so I guess there is no voltage.

You can check by probing here.

See the + and the ground goes to the screw/flashlight body. When powered you should be close to battery voltage, 3 or 4 volts. If no voltage, the wire to the aux board is not connected.

Seems the wires are not connected. I asked Jack to turn them off not to disconnect totally rofl, lost in translation apparently and my fault for asking for changes.

Sounds like they did exactly what you asked to me.

What are the smaller and different looking blue and green wires? They seem to be looped up there for no apparent reason. I wonder if one of them is the power that goes to the aux board?

Yes, that is exactly what Ryzbor was showing. On request to turn off the aux LED board, Fireflies disconnected the aux LED board.

This was probably done because there is no other way to turn it off. Later models like the E07 switched to a 3-wire setup which allows the MCU to turn the board on and off, but on the ROT66, it’s wired directly to power.

Can someone show a ROT66 with all 4 wires hooked up? I could not find any pictures.

Nice, now Ryzbor can connect them if he wants.

Would it be possible for one of you to post a graphic illustrating where the potentiometers are and how to adjust them? I’d love to be able to ramp mine up a bit. I love the aux leds.

They are labeled POT_D1, POT_D2 and POT_LVP. There are 3 of them and they have the Philips head adjustor so you can turn them with a screwdriver. D1 looks to adjust the outer ring, D2 the middle ring and LVP adjusts the inner ring.

Look at the 1 o’clock, 2 o’clock + 7 o’clock position

Awesome! Thanks.

Thanks all! JasonWW that would mean I would practice my first soldering on the ROT

Being able to solder let’s you do a lot more stuff. It’s a good thing to learn. There are lots of videos on youtube.

Maybe you have a friend nearby that solders?

If possible, practice on some junk boards first. It’s a good way to get a feel for soldering without any real risk or consequences.

after receiving the E07, I realized that my ROT66 somehow has different programming? I can’t get to turbo, only to the top of the ramp.

For example, it should to go the top of the ramp when I double click, then another 2x click to turbo. But on the ROT66, it goes to strobe when I do the 2nd double click, not turbo.

How can i get turbo back?

I’m guessing your E07 uses Anduril and your ROT66 uses NarsilM. You might want to check this.

Is it an old ROT66 before the AUX LED's in the head? If so, might be NarsilM. Once the AUX LED's were added, they went to Anduril, I believe.

No, I have 2 with Aux LED’s and NarsilM
