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

I thought so too but since I am not electronic expert I would not know where to put it, across which component (presumably somewhere after component that controls current supplied to leds)!
Thanks :bigsmile:
P.S. If you make a short circuit across one of the 39R0 resistors this little puppy will shine even brighter on MAX, same applies for 100, 200 and/or 102 resistors on 6 LED version with TSA Silly

This ramping Mini paired with the ML-102 is honestly all I ever wanted from a Zebralight. I was always put off by the modes. Now I have a nice portable floody moonlight, and it’s modular too. ^^ Maybe I am strange but I love solutions like this. Thanks again, Sirius9!

Thank you! Maybe I need to delete one post and vanish into obscurity like so many before… :ghost:

It took me a while to find a large enough value surface mount resistor but I made the USB light from FastTech moonlight with 1.3K. It draws 0.1mA more than the Mini. >.< I do have an SMD diode but with that it is too low. Maybe changing the two diodes to slightly higher but I am not that fussed.

Here’s a small comparison pic with the Mini on the right (with Tungsten white balance the Mini looks slightly pinkish and the FT slightly green):

With auto white balance the FT looks greener while the Mini looks more neutral:

i agree with chloe(^^)

i bought one from the 1GBP shipped seller linked before and ordered another. if you have a monitor with usb ports it’s fantastic for ambient lighting (and keeps the level in memory :/) love fade in/out on power and the reversible design too, so well built!

I just got my shipment of MINI's:

I ordered four via this ebay seller; two each of the cool white and warm white variety. Now $2.35 shipped, was higher when I bought mine (I paid $2.93/each). I do prefer the warm tint for normal use, not sure if I'll be using the Cool ones as much. Also, they seem to get quite hot when running on high-mode for an extended time. Not sure how hot, I'm planning to check the temp when I get some time to play with them more...

I do like the low-mode and the ramping function. I bought these to use with my ENB triple-18650 power bank but unfortunately, the lowest low mode seems to draw so little current that the ENB shuts off completely after a few seconds of runtime. On high, it seems to work well though, and I think this would make a nice long-runtime camping/outdoor lantern for times when a lot of light isn't needed.

I've just ordered one of these:

http://www.ebay.com/itm/271405911472

...to use with the ENB bank to allow two of the Mini-type lights to be used at once for double-light or to allow 360-degree lighting with one mini facing each direction...

These do get a bit hot if left on high.

I received the cool white version this week. I am not as impressed, it is slightly greenish white, feels a bit sickly, so I might mod it.

I tried to capture this in sunlight but my camera is biased to make the cool white look white.

Here is a comparison instead with cool white Cree XP-E (left) and cool white Mini (right). The white balance makes the Cree look more blue of the two. It may be a personal and subjective thing but I find the CW Cree is rather cool and doesn’t feel sickly.

Got my touch-sensor one recently.
I bought the 1 GBP (Great British Pound) one, warm white.
It is slightly hinting towards a mustardy greenish tint.
Touch sensor sometimes doesn’t sense my touch…
PWM noise on low…
Gets a little hot on high…
Yet, it’s a nice lil’ device.
Makes me smile.

The daylight sensor one is on it’s way to me also.

I received mine with touch sensor, WW, ordered for GBP 1. I didn’t notice PWM on highest or lowest mode. On other brightness levels I could only notice it by looking at PC fan. When powered from computer’s USB it gets warm, but not too hot to touch on high. When powered from 220v to USB adapter on max it gets much hotter, too hot to touch.
I like the tint, didn’t notice any traces of green.

Thanks for the heads up. The fact that MINI can be inserted to USB connector both ways really makes this interesting.. Ordered "some". Smile

 

I really love these lights. First I ordered three from eBay. When they arrived, I instantly ordered three more. And then "couple more" from BG to be gifted away (the price is nice when buying 10 or more and using the BLF coupon). And then some more.. Sealed

The above mentioned splitter will be handy, together with these 360 degree USB adapters.

 

One way to use these lights is to provide smooth flood light in ad hoc product photography, like this:

I hadn't thought about the swiveling USB adapter...

Whoops... I think one just got added on the DX order I was just about to make... How did that happen? Wink

My wife has that same rug; unfortunately, her cat decided it would make a great alternative to the litter box. I guess she thinks it's grass???

A couple of additional observations on my MINI lights...

I ordered a total of four at the same time, and fromt he same eBay seller; two each of cool and warm tints:

The two cool-white lights aren't bad; they have a cool tint that's not overly offensive if you don't mind CW tints. Both of the cool white MINIs have a quiet, but noticable, whine at a mid-range brightness levels. The whine isn't audible at the lowest and highest brightness settings, but as the brightness ramps up or down, you can hear the whine fade in and then out.

The two warm-white lights don't have the same whine, but even though they were purchased together, have a vastly different tint to the LEDs. One is a pleasant creamy/warm tint. The second, even though superficially the same, has the unpleasant puke-a-tronic green tint to the light. No pics yet...

I plugged all four into a USB hub... That turns them into a mini stadium light... Cool

My warm white developed a faint whine after having it on high for a while.

I did some tinkering with the Mini but nothing exciting to report. I tried some bigger caps (100, 220 uF) but it wouldn’t hold memory of the mode for very long, and it only worked if I turned the Mini off before unplugging.

Any idea how to mod these so that as soon as they get power, they would light up?

Are the SMD components likely to be damaged easily?

I was thinking of putting some thick tape around the edge of the board so it protrudes just a bit higher than the level of the components, creating a temporary reservoir (not on the connector plug part of course) then filling it with some UV setting glue so they’re all encased and the unit is more rugged.

Edit – here’s one i made earlier, much tougher

UDO: for that you would need to bypass the mcu or just buy cheaper version that does not have sensor and it’s on instantly when you plug it.
CRX: they look pretty sturdy to me, I would say they will hold rough handling just fine.

The problem is the switch must be reset, so even if you wire it to come on on insertion, you need to break the connection to reset it, to be able to make it ramp. (I tried replacing the touch control with a push to make switch).

 Got 8 of these  (4 warm white, 4 cool white) from this seller for $1.82 each. I'm really liking them

I keep one plugged into my computer so I can see the CD/DVD Burner. It's dark under my desk.

My two warm white minis arrived very fast from China. Wish I had ordered 20, they are great.

Mini is quite catchy :bigsmile: I gifted a few of them to non-flashlight-addicted friends and the find it interesting also.

Darn, sounds like they can’t be made to turn on as soon as they receive power.

I was thinking of putting a USB power adapter into a switched wall outlet, putting a stiff “worm” style extender on it, and putting one of these lights on the end of that… which would then let me turn it on and off with a wall switch. But if it doesn’t come on when it receives power, that wouldn’t really work.

The plan is to put one or two directly behind my television so it’ll be backlit. I currently have sort of a prototype running, but it can’t be turned off without reaching behind and touching the switch.

There are some that have no switch and turn on when inserted? Though these are quite bright:

Oh, I just checked newly listed and they have 5 cool white for 5.58 USD:
http://www.fasttech.com/products/1/10006956/1741602-6-stw8q14be-100lm-60...

They also have the kind with pot and sensor (5 for 5.08 USD, warm white).

I plugged one of my minis in my Raspberry Pi which is on the back of the TV and I just leave it and the Rpi turned on all the time.

I’ll probably just order one (or five) of each, and use whatever works best.

Originally, I was planning to do something much more complicated… but I’m not sure if I’ll ever get time. The plan was to put an XM-L2 or maybe XP-G2 triple or maybe a MT-G2 (at low-ish power) on copper and mount the copper directly onto a CPU heat sink, mount the heat sink onto the back of the television, and run them with some sort of common qlite driver or something, via a power converter plugged into the switched wall outlet. Then I could control the brightness via the wall switch, and it could go up high enough to make regular room lighting unnecessary.

But it’s a lot easier to just stick a USB dongle in and call it mood lighting. Smile
(the photosensitive ones look particularly promising, since I could just leave it powered on all the time)
