Hello guys,

I got problem in my ups few weeks ago which is is turned off immediately after a power cut, so I contacted Apc by email they said it is out of warranty and it cost 400 for visit.

Then today Apc service man called me and said 400 for visit and 2.2k for each battery, he came and check said battery dead and replaced with 2 new

He taken the old 2 batteries for 200rs total I paid 4.6k

I want to know it is how works and charges are correct let me know ur experience

I feel like it’s too expensive and I just brought it oct 2023(5.8k) just in 2.5yrs it’s dead? And he said batteries only last few months after warranty period.

Plz tell ur opinion.

I saw this in olx first shocked to thought might be scam also thought it can be real,

First I contacted him in olx he just sent his number told me to call or message, I messaged him,

Then I confirmed it is a scam coz he said it is brand new sealed if he said 1 or 2yo i might hav believed it.

I asked his shop location he just sent me long message pay advance then that then this. I again asked can I come in person he said no I said bye.

So guys be careful in this time lot of scammers will try to scam in current PS shortage, don’t get fooled!

I randomly saw this super cool DIY idea on Instagram Reels and now I can’t stop thinking about it 😭

It’s like a magnetic fridge music player that looks like a mini vinyl setup. The player sticks to the fridge, and all the small “vinyl discs” are also placed on the fridge. When you put one of those discs onto the player, it automatically plays a specific song.

From what I understood:

  • It probably uses NFC to detect which “disc” is placed
  • The disc doesn’t look like it actually stores music, so I’m guessing it triggers audio somehow?
  • The player rotates like a vinyl, but I have NO idea how that mechanism works
  • It also has lights that glow when you place the disc, which makes it even cooler

I’m really curious how this whole thing works:

  • What components are used inside the player?
  • How does the rotation work? (motor? sensor?)
  • How does NFC connect to playing music?
  • Where is the music actually stored?

I’m not very experienced with electronics, but I really want to try making something like this as a project.

👉 Does anyone know how this works or have seen a tutorial for something similar?
👉 Any beginner-friendly guidance, parts list, or YouTube tutorials would really help!

Thanks in advance 🙌
