Hello everyone !

I'm seeding/cross-post this in 3 communities because I think I will get better answers in each respective one (Hardware, coding, electronics).

As the title say I'm want to learn to build from the ground up those cheap solar led/optic fiber lightning, here some images to get what I mean:

They come in bundles but after awhile they just die out without repair ability which kinda sucks and because they are cheap my mum keeps buying them... So, I would like to build ones I'm able to repair and customize :). However I have absolutely NO idea where to begin and what exactly I'm searching for... I'm lacking the skills and knowledge on the 3 fronts !

  • What hardware I'm looking for ?
  • What kind of electronics ?
  • What programming language to glue everything together?
  • .... ?

I'm not afraid to get my hands dirty and learn how to micro-solder, learn some coding skills to get everything neatly glued together software wise, learn the necessary hardware or other important and necessary stuff to achieve this goal ! I'm looking for every good and reliable advice to get me started !

One thing though, If i have to learn some hardware/low level coding skills I would prefer a language that would be useful for other stuff in the long run.

Thank you in advance and I'm already sorry if I'm very slow to respond, I'm not native and the flood amount of information I will probably get, will surpass my ability to respond to everyone right away.

Also every other directions are welcome, like:

  • how to repair the old ones? Do I need to flash their proprietary software/hardware?

Thank you !

I would look into raspberry pi or arduino; both of those has thriving communities and lots of guides.
A couple of guides for the solar powered part of your project:

This looks very cool stuff however these solar panel lightning bulbs are autonomous and their form factor very tiny. Raspberry pies a very cool stuff to tinker and learn stuff but they are not exactly what I'm looking for.

However your link is interesting ! It seems they have some tutorials for basic electronics :) that's more like what I'm looking for, so thank you very much for the pointer !

Edit:

Yep, https://www.circuitbasics.com/home/electronics/ is very interesting ! Thank you for this.
