Thanks for the night shots. It looks really impressive.
Now that’s a good one for my wallet, and I’ll need one for my PC, and car, and I guess I could just get a half dozen.
Hmmmm with a USB to micro adapter could this be a low draw option for phone?
I doubt it, I checked my phone and tablet, usb ports are not powered, maybe they can only accept charge (and data) via usb port!
Thanks for the mini-review! :bigsmile: I had to get one. I already have this one from FastTech but it is too bright for a nightlight (maybe replace that 22R0 resistor).
Here is a “beamshot” at 1 metre, 100 ISO:
You can see it puts out a lot of light.
I ordered one from this seller for $3.56 free shipping
I am assuming he is talking about an OTG adaptor?
what is the PWM like?
You’re welcome 
22R0 is 22 ohms, so it’s not some ultra low value, I would try to get 20-50 (or even 100 ohm) trimpot.
OTG or not it is just an adaptor, if there is no current in a USB port adapter cannot make it. Or maybe I am wrong!!!
Either there is no PWM or it is very fast because, when looking through the camera, there is no flickering at all, no matter what intensity of light I set.
The adapter signals an OTG device (through the usb ID pin) to switch into host mode. Only then will the OTG device start to supply current. You can also sometimes switch into host mode without an adapter.
Not all phones or tablets support usb OTG / host and some that do support OTG don’t even supply any real current when in host mode.
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?
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
- 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 1x18650 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:
Just received mine, fun little thing ! 
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!!
