Hello toykeeper, thanks for pointing that out do you know what kind of problems do that caused? I mean, is it some obvious malfunction or is it more about working regularly for a while and then risking to fail later?
What happens is that the driver reboots. When the FET opens it lets current through, then when it closes it causes kind of a shockwave strong enough to reboot the MCU. So, in the strobe mode, for example, itâll flash once or twice and then go directly to moon. Or it can go from turbo to moon, or one of the higher FET modes to moon, on its own.
Basically, if it runs at full power it reboots itself and goes to moon.
The attiny13a is tolerant enough to keep running regardless, even when itâs getting far more voltage than itâs specâd for. But the attiny25v doesnât respond well to these voltage spikes, and it reboots.
Newer driver designs eliminated the voltage spikes, but I donât think banggood has any of those newer designs.
Thanks g_sintornillos ,
anything I should be aware before ordering? I see that many people were not satisfied with QC, mostly damaged emitters, leds with different tint etc!
I wanted to go for Nichia version.
First batch was for oblivion, high failure rate and DOA, then improved
I do not know whatâs happening with the current batch, Astrolux is not characterized by having a minimum quality control, it can be a lottery
Mine, from second or third batch, bought at the end of 2016, works fine from out the box
Thanks, I wanted one for a long time but all this hiccups turned me off, hope they improved the light, wouldnât like to get faulty nichia led, donât have those at hand.
For those interested, I bought the Mateminco S01, which is the same as the S41S except they use the 5000k 219B emitters. The tint is better (less green) than my Astrolux S42 5000k 219c, and both MF01 with 5000k 219c. I asked the seller and they confirmed it is still the 219B. The quality is awesome. Very heavy in weight and good heat shedding from the copper. I hated the Astrolux S42 but I love the Mateminco S01. It has memory mode same as BLF A6 but its much brighter than the A6 from ceiling bounce test.
I donât have an account there, but could you let the seller know theyâre legally required to state that the product uses open-source code and provide a link to (or copy of) the source code?
