What can I do with these?

So I bought a couple JKK flashlights from a taobao seller, and I realized that they sell some parts too.

With my very limited electronics knowledge, I see that they include LED already seated on a PCB (not sure if this is the correction description), reflector and the “driver board” PCB.

Aside from using them as spared parts, I wonder if it is possible to make something from them, like connecting more of the LEDs and hooking up some battery holders, perhaps make some panels for use, or even a “Blitz Shield” for fun? That would definitely be a blast. Haven’t solder before but from members’ post that should not be too hard. Would really want to learn more and make some DIY stuff. Thanks.

I would practice soldering first. Yes anyone can do it but it takes years to master. Also you should watch a basic electronics video.

If you want the maximum benefit, better go into this with some knowledge.

you can do ANYthing with them.

i recommend - practice - with them.
cut/glue/solder/etc. find out what works
and what does not so you are ready when
the modification means something for real.

Thanks guys, have looked into it. With the abundance of ready use boards, think I may make something out of them.

It's a pleasure to know you, ftgfop!
