Is the paste conductive enough to run before it reflows fully? Maybe just stick the emitters on there and crank the power up to 100% until they reflow themselves.
I was thinking the other day……… geeeeez, in the wrong hands this is an accident waiting to happen. Like George Carlin said “ think for a second how dumb the ‘average’ person is……. then half the people will be dumber than them” I don’t think anyone that knows what they are holding will have problems short of an accident but think of all the folks(especially yunguns) that might turn it on without knowing that it is not just a ‘regular flashlight’.
I was in particular thinking of a young kid(3-5yo) that might turn the light on then drop it on something flammable. Its just scary.
My V2 219C Emisar D4 blinks/flashes twice whenever the tailcap is loosened more than about 1/10 turn and then re-tightened.
I couldn’t find anything here about a “feature” like that, but the thread about the “Noctigon Meteor D4” at the other light place says “LED flashes twice when tail cap screwed on with unprotected battery in.”
I don’t think that’s the case here, as putting a protected cell in my D4 did NOT get rid of the double blinks (but it did make me feel kind of stupid though :person_facepalming: ).
All three of my D4s blink twice when a fresh battery of any size is put in. (Samsung 30q, Efest 18500, Aspire 18350). I think this is just a feature to let you know the light now has power.
Did a little realtime usage test of the D4 with a first gen Aspire 18350.
First with the light completely static, no fan or cooling shining into my isphere and then another test with more normal usage, moving around, changing hands, positions etc.
This test really shows the value of using one’s hand as a heat sink.
It looks like you set the temperature ceiling to 35, yes? The units are approximately in Celsius, though they vary significantly from one MCU to the next. Regardless, 35 is pretty low. I’m not surprised it ramped down farther than necessary with a low target level and no cooling.
Yeah, a bit annoyed at that, I was playing around with it yesterday and must have left it at that low level, didn’t check the temp setting until afterwards. Still, gives an indication. 3 blinks then 5, 35 :+1:
FWIW, the default temperature limit is 45, and the maximum is 70. It has no minimum, but if you set it below room temperature it’ll step down to the lowest allowed level and stay there.
If you try to set it to a temperature below 0, I think it may interpret that as 255, then save a value of 70 to eeprom. And if you actually manage to save a value higher than 70 to eeprom, it’ll set that back to 45 when the light boots.
The tempcheck mode reads 0 for any temperatures below 0. At one point, it’d wrap around and give below-freezing readings like 252 degrees (25 blinks, pause, 2 blinks), but I fixed that.
is it possible with current driver configuration to blink and show battery voltage like when power is connected just like what Nitecore did with some of their lights?
You can check the battery voltage at any time by triple-clicking. It will blink first telling you the number of volts, then pause, then blink again for the number of 10ths of volts.
