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.
Nice test CRX.
What emitters were in the D4 you tested?
Nichia version.
That is correct. It blinks when power is connected, simply to indicate that it has power.
Looks like 400 to 600 is its happy spot when hand held. Nice!
That’s my happy spot for real world usage. :+1:
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:
Has anyone made a video of the UI yet? i have yet to receive my D4, i just want to see it in action! haha.
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?
Belt and suspenders. I like it.
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.
Sure, if you change the code. Then it can do a battcheck instead of the power-on blink.
It’s not quite as excessive as it sounds — the eeprom is all 255 by default, so the “suspenders” activate at least once on first boot.
ah i see thank you.
I’ve looked into it once or twice. Do you have a few thousand dollars? :money_mouth_face:
Or a green glass filter, but then it needs to be cut and attached.
Which is why Richard is the best!
Did a run at 57°
