Hello everyone!
I have a problem with temperature meter in my GT mini torch. My GT mini blinks 30 degrees when the real temperature is about 15 degrees. Has anyone the same problem? Is it possible to calibrate temperature meter by user interface? I have a big BLF GT too and it measures temperature perfectly.
It will always be off. It’s no big deal. You can set the step down temperature to whatever you prefer.
JasonWW thanks for your reply. I’m searching now for information how to calibrate temparature meter to show real temerature properly. Temperature meter is a nice function for me and i would like to calibrate it. Has anyone the same problem with temperature meter?
Nobodies light reads the correct temperature. This function was never meant to be used as a thermometer. I’m not even sure why it was added as a function.
The only way to fix it is to reflash the driver to Anduril which has a way to let you offset the temperature calibration.
So now it’s time to add to narsil firmware new function - termometer calibration:).
I think that it is a good feature to measure real temperature of driver inside the pill.
No, the software does not allow it. You would have to switch to Anduril.
There is no real reason for a calibration. You don’t set the thermal stepdown to a number, you set it by how hot it feels, or by a time limit.
The only reason ToyKeeper built a calibration tool in Anduril was to make it easier at the factory to get consistent thermal stepdown temperatures.
Now that Tom E does not visit here much, there will be no big upgrades to NarsilM. Luckily ToyKeeper is still around and she is able to make upgrades to her D4 (RampingIOS) and Anduril, etc… User Interfaces.
My BLF GT measures temperature properly so I thought tha GT mini should do it also. My GT mini has temperature mistake over 10 degrees.
Where is the thermal sensor on GT mini board?
I think it’s just a lucky coincidence your big GT reads so close to accurate. They can sometimes read plus or minus 15°C.
The temperature sensor is inside the Atiny85 mcu.
I have 3 lights using Narsil and I think I’m lucky as they only vary about 5°C between them. It is the luck of the draw if it happens to read close to accurate.
So, here another picture of my GT mini that has an off-centered XP-L HI. Until today, I have not received any response from Neal. :-(
I just hope that bezel can be unscrewed somehow by using a strap wrench. What do you guys think? Is it worth the effort or should I leave it as is?
The spot on the wall looks quite patchy but my camera won't be able to capture this for the sensor will automatically adapt to the intense brightness.
Intense brightness? Turn it down real low.
Does it really affect the beam? it must be minor differences or am i wrong ?
I don't know how to really describe it. One half of the spot's rim (zone between spot and spill) is a bit eclipsed and the other half looks as if the brightness "bleeds out" into the spill. I need to fiddle about the right camera settings to make this visible on photo.
Try turning down the ISO to 100.
I think what you’re describing is a lopsided corona.
I opened up a friends GT mini for him and removed the driver, flashed Anduril. Now, I know good and well that my own did not react well to Anduril being flashed and I even lost the light at the switch. But wouldn’t you know it, this one flashed perfectly! The green light came on when I clipped on the Pamona clip, went off when the flash was in progress, came back on when it was done. The light works perfectly. Have no idea what would be different but of course my own was much more problematic, even much more difficult to remove the bezel… this one the bezel came off pretty easily.
And so it goes…
He has been traveling I think he is back now, I will try and get a hold of him for you.
Do you mean Neal? If that’s the case, thank you very much for your help! 
I would be really glad to hear some feedback from him.
Thank you JasonWW. I‘ll see if I can manage to take a good picture of it.
Yea Neal, I will message and let him know someone is trying to get a hold of him. I am sure he will take care of you, Neal is the man.
Unless I missed someone, I count 14 people to date who have posted about switch problems. They are….
Anyone else having any type GT Mini switch problems besides the people I mentioned above??

List updated. Jhicks2018 replacement head arrived.
Did you get any response from Neal yet? Meanwhile I sent him another PM but I got no response either. Somehow I begin to feel quite irritated. 
Anyway, I appreciate your efforts to help me.
