I wonder what that MCU that is controlling the PWM is…love the ramping feature though…most awesome!

way freeking cool…the one I got, is pretty much off or on…but can run an INCREDIBLY long time on a single 18650 portable power supply

what happens if you wave it around fast? any flickering?

edit: a few more questions…
- what size led is it? a 3014?
- when you say you can run it off a li-ion, do you mean a battery or a 5v battery bank?


- No, no flickering whatsoever, I tried with several settings and it’s always full line.
- I would say that led’s are 5730.
- I was thinking on a battery bank, like 1×18650 but maybe you could solder leads to a cell!

My Mini arrived today!! ^^ Two wishes would make this perfect; default ramp low-high (instead of starting high-low), and remember the last setting between unplugging. Actually, with memory it would make the default less of an issue. Maybe a button cell to keep a standby current? Hmm…

My mini behaves like that! When I plug it in -> first touch and it goes from low to high.
But yes, it does not remember mode setting if you unplug it, maybe adding big value smd capacitor?

I just got mine, fantastic little thing. Warm light (maybe a little bit too warm), sensitive touch, nice low level. When you turn it on or off it has smooth start, I noticed it only in a couple of pretty expensive flashlights (and I paid $1.66 shipped!).

Yes it is this initial ramping. After it peaks, it is then possible to set.

I have ordered another in cool white. :bigsmile:

I just ordered four via eBay @ $2.93/each shipped. Two each of the warm and cool varieties. This may be the techie stocking-stuffer item for this upcoming Christmas. This, with my 3x 18650 Power-Pack should give me a decent run-time nightlight for power outages or while outdoors...

Now, to use all four with my USB hub... And the high-current output of an iPhone compatible power-pack...

I missed seeing this review until now but I'm glad I did.  I have a simple 3 LED version without the touch and I use it all the time in the kitchen.  I remember this touch sensitive one when it was released.  I figured it only turned off and on and would be too bright with 6 LEDs.  Now that I know it ramps I'm snagging a few of them.  Awesome sauce!!

That's actually the same seller I ordered mine through... Only mine was $2.93/each, which is the currently listed price. You saved .04 each! Money Mouth

I am glad that many of you are satisfied with Mini, I can’t wait until the version with photodiode gets here and also few of warm white Mini’s Smile

A version with photodiode?

I made a video with USB Charger Doctor connected to show current:

Photosensitive version on ebay.
Thanks for the current consumption video, so, we can power this thing in moonlight mode forever since it draws 0.00A :bigsmile: (just joking Silly pity USB doctor does not do microamps).
P.S. I ordered USB Charger Doctor too, from DX for $3.78

It is more like 280mA on high, 2.2mA on lowest (here autoranging meter would be nice):

The LEDs seem to be Samsung LM561B.

I concur. page 19 shows the same black dot on the led. appears to be the 5000k version.

If you can’t blind them with your brilliance, baffle them with your bullcrap.

Hi Chloe.
Couly you tell me something about the warm tint? Is it good looking or awful yellow? PWM is visible?

It is not a terrible warm tint. Maybe a bit warmer than I’d like though. I could not tell any PWM with my camera or moving the light around.

Here next to a Nichia 119, 3500K (right), the Nichia looks more neutral, though slightly green, where the warm white Mini is slightly pink:

And for extreme contrast, next to cool white XM-L not very flattering to either tint.

I received today another CW, WW and WW with photodiode. I like the WW version, its nice but I am not too happy with the self adjusting version, It flickers a lot Flat Stare

Maybe the photodiode is too sensitive? Try to put some light diffuser on it.

Thanks for help Chloe Smile

I presume that also, will try the trick with difuser, thanks, if it works I may try to use white nail polish :bigsmile:

In the meantime, you can wave the mouse over this image Silly

Is the 3 LED version with photo diode noticibly less bright on full brightness than the 6 LED version (without photo diode)?

Does the 3 LED one have PWM or is it the flashlight causing the flickering?

Yes, about 50% J) Just joking Silly actually, it appears they are about the same intensity if 3 LED is not even stronger, yes you read that right. Can’t test them both in the same time obviously but 3 LED version apperas “a hair” stronger.
Chloe wrote:

3 LED Mini is flickering Sad It seem that the led intensity control depending on a photodiode input is straight forward, IF -> THEN, without any averaging and when the ambient light is on some margin LED intensity “jumps” up-down.

Did you try to adjust the sensitivity:

Does it flickers even when on full brightness?

Be careful adjusting those pots, they can be delicate.

Yes, I tried to adjust the pot but it only affects to photodiode sensitivity, flickering is present mostly in lower part of intensity scale, no flickering on max…

Maybe a cap or two to smooth the flickering? Nice collection! :bigsmile:
