Tiny USB lights

Once it’s cured with UV, you should have a sticky but shiny surface…
The problem is that the sticky finish will collect fingerprint, pocket lints etc…
So you have to polish it, on a denim jean for example…

I guess the sticky surface is no good for output…

Indeed, sticky finish is what i get too.
Clean and polish then.
You did a nice job at that. :+1:

I’ve got this type of a light today. White.
It’s a bit larger than I expected really.
Has no UI, plug in to turn on. Beam is mostly rectangular, not clean. Very cool ugly tint. I don’t like it.

It would be cool to have a micro-USB sized light…Type-A light + micro USB adapter = not so tiny….
I did a quick search, failed to find anything.

I wonder if it would be easy to use oshpark or similar service to make a simple light with Optisolis and resistor…

I’ve got my second set.
Warm variant of these:

Beam is artifact-free. Tint is OK. I like….but they were too large.
So I decided that I wanted to be like CRX, took a file and worked on it until I liked the result (checking if it’s still working from time to time).
At one plug-in, there was a blink and the light went dark.
No good.

So I took another, filed a little less. It works and is significantly better than stock. And it weighs 13% less too! That’s a whooping 0.4g saving.

In my powerbank:

You know you’re a true flashaholic when the powerbank you attached your USB light to is a flashlight in and of itself :smiley:

I intend to use it as an alternative to diffuser that weighs less and produces warmer light. :slight_smile:
Will it work well? I’ll see. :slight_smile:

I have a couple of those that I justed used with my power banks during a 3 day snow storm power outage. They were easily as useful as my fancy expensive lights!

Yep, and the WW ones are soooooooooo inviting…

I found an RGB variant with a physical switch:

Dang, what dungeon did you crawl through to find this treasure? :smiley:

Actually I stumbled upon it while looking for something entirely different. I think powerbank controller boards with Type C. :smiley:

I got the ramping version, which is a little touchy (no pun intended). It’s kind of random what level of light you’ll get. If I buy more I’ll look for a different interface.
They are cheap ($0.89) enough that I bought a handful. I left them in the little plastic bags they came in and distributed them liberally. There’s one in my backpack, wallet, bag of cables in my laptop bag, desk drawer, and rubber-banded to each of my power banks.

I’ve got a few like the ones in the first pic. I hardly ever use them but they are a little bit of insurance that takes up practically no space in a computer bag, belt pouch or even a wallet. There’s USB ports practically everywhere so why not?

Here’s a chainable variant:

A really small dimmable variant:

Is it compatible with Optisolis? :wink:
I won’t check, I expect it to be quite dim but I do wonder. And I’m really amused by the small number of components. Simple! :slight_smile:

2-sided RGB:

I was not aware of such extensions:

Nice. :slight_smile:
I wish there were somewhat larger and brighter tiny lights. Put 12-18 5730 LEDs on one side, control on the other. Won’t weigh enough to stress USB port and even with limited cooling it will be bright enough to be useful.
I tried learning PCB design twice already but with no electronics knowledge it doesn’t go smooth. Maybe the third trial will be more successful. :wink:

Nice find. Heck, instead of using a work light as a powerbank, turn your power bank into a worklight.

Also,light with Color LED

Anyone how to change German to English in Banggood so I can
Buy some toys, please.

NVM, danka. Changed. :student:

Is it USB-c? Standard? I don’t understand what they plug into.
