I’m disappointed too about the visible low frequency PWM in the pineapple, did not expect that here (I bought 4 drivers from Rey), I thought we left that behind. And Rey should be very aware of our concerns about low freq. PWM, back in 2012 upon our request, he already arranged for his Trustfire Mini-01 group buy light that the PWM frequency went up from under 500Hz to about 1000Hz (I’m ok with anything above 1000Hz).
2 kHz, but the problem is the low duty cycle (short burst of light, long period of darkness), which makes it very visible. On the highest mode the duty cycle is high, so it’s not very visible.
Possibly the capacitance in my leads makes the signal trailing edge slow. So ignore them, it’s just a photodiode directly connected to the scope.
Ok, 2KHz is not too bad IMO, even in a low duty cycle situation. I was fearing we were back to 500Hz. Still a pity that this driver could not be done with over 5KHz PWM, or true current control in the lower modes.
So there is still a duty cycle going on on the highest mode? Sounds unneccesary.
Sorry, I was told it was 2K Hz, thought it’s fine. Higher PWM might cause a worse runtime.
Will talk with them if there is any way to improve for the next batch.
Rey, 2kHz PWM is visible but I usually do not find it very disturbing, and I think most normal people are ok with it, but we are not normal over here :innocent:
And I agree that maximising runtime is important too.
Received mine. The LED isn’t quite centered and there’s a bit of side play in the switch, but other than that it’s fantastic. The threads are very smooth, probably the best of any of my flashlights.
mine arrived in the bay area last week but traveled up and down the peninsula for some reason. Hopefully it will be in my hands tonight when I get home
Mine was waiting for me tonight after work.
Yup, beam perfectly centered.
At 1st, I thought that moonlight was not bright enough, but after playing with it
for awhile, I realize that moonlight is exactly where it should be.
This light is much heavier than I expected, and that’s NOT a complaint.
Beautiful light!
Rey, thanks so much for this!
