DIY flashlight.

You will need
23mm diameter lens from Aliexpress (link is an example, there are plenty of those around;I had a couple lying around; they all have a small brim which allows it to be installed in this model)
14500 lithium battery (almost the same size as an AA battery, I believe, but AA wont work)
I used a constant current LED driver from this link at Aliexpress
An LED (e.g. 1W; recommending full spectrum)
A charging board / battery protector based on TP4056 such as this one (micro USB or USB-C wont matter)
Some wire
A rocker switch like this
A battery holder such as this
Some photos to illustrate the assembly:



Solder the parts together using some wire.
Use solid wire to solder the LED, so you can position it under the lens.
If you want, you can add some aluminium foil under the lens like I did in one of the images.
