Although this USB rechargeable strobe is probably intended for bikes, this could also be used as a warning beacon for other purposes.
Note that it has a very small rechargeable lithium cell in it, so it's not really going to be very useful for 24 of its 31 modes, but the short duration double pulse modes in 7 colours should have a decent run time on a charge.
Yeah, that's 31 modes! And you're gonna have to mince through them ALL to get to the one you want. But fortunately it holds the last choice in memory.
A long press turns it on and off, while short presses step through all the modes, which are:-
Low current short double strobe in white
Flashing in white
Static white
Then the same again for red, green, blue, yellow, magenta and cyan.
Double white flash and single red flash.
Double flash sequencing through all colours.
Slower double flash sequencing through all colours.
SOSOSOSO (SOS?) in white, red, green, blue, yellow, magenta or cyan.
The keywords to find this type of light on eBay are:-
7 colors usb strobe
Reference price is 3 to 5 £$€.
The lithium cell has a capacity of around 35mAh as opposed to the 90mAh stated in the data sheet. It charges at a squirmy 10C (350mA).
The case is not waterproof, so moisture will inevitable creep in when used outdoors and potentially cause corrosion.
The circuitry is very typical of this style of unit, with the classic SOT23 charge chip and ubiquitous 8 pin microcontroller. The use of A2SHB MOSFETs is nice.
The module itself would be useful for pairing with a larger lithium cell.

    Looks a cool gadget maybe run a few on an 18650 by modifying the usb socket to just power it and remove the tiny battery….the possibilities are endless thanks Clive

    Life is stressful enough as it is, any light that has more than a simple on off, it’s too much anxiety for me… The guy that designed this light was truly a disturbed sadist…

    I'd put a better battery on it.. This isnt good enough to be a bike light.

    I have 2 of these lights, and have another 2 in the mail. I like them. They are cheap and have an interesting flash pattern. I use them on my electric scooter. I think their maim purpose is to be used on small quadcopter drones due to their small size.

    It's not an SOS mode, it's for mothers wanting to morse "Told ya so so so so so so so so" from afar.
