Today I jumped back on this project that has been on pause for about a year :)
Turning cheap defective desktop speakers into a set of wireless Bluetooth stereo speakers.
Got the idea from this video from DiyPerks.

I'm trying to recycle as much as I can:
Desktop speakers were defective and given to me by family,
Bluetooth receivers are from old earbuds,
Batteries come from and old powerbank,
Charging module from old vapes (still need to figure out a few things about them, not sure I'll end up using those).
The only thing I bought so far are amps for the audio output tu the speakers.

Any input or advice is welcome :)

I'll keep you updated with more details if anyone is interested

I thought these were huge for some reason until I saw the battery lol

Major props for upcycling this project!!

My first thought from the thumbnail was "Dude should use a few 18650s for power" but upcycle is better!!

Thanks! I kind of became my friends' and family's recycling center ^^
I'm accumulating a lot of stuff but that gives me the opportunity to tinker without feeling too bad if I end up messing up :)

The speakers were defective? How can you still use them then? Are they active ones?

[–] MacAnus@sh.itjust.works 3 points 4 months ago

Yeah sorry that wasn't very clear: the only thing wrong with them was the cable used to connect them to a computer.
Now that I think of it there might have been a little amp board in the volume selector switch that was on said cable.

I'd assume the electronics failed. The speaker itself is probably fine.
