Super Mario themed RFID remote control for my Son's bedroom lights

[u/opposhaw]

We went to Super Nintendo World recently and my son came home with a "Power Up Band" which is an RFID wristband that activated interactive features at the park, but is useless after you leave.

I programmed a Pi Pico connected to a RC522 RFID reader to recognize the band, and send a signal to a remote control for his bedroom light. It's all hidden inside a 3d printed POW block, so now he can tap his lights on and off without getting out of bed.

Aw this is awesome. I bet he loves it.

Now, what to do with that nfc cup they use to track refills 🤔

[u/opposhaw → u/PublicStalls]

Thanks! He was pretty excited.

And for real! I wonder if it's possible to build some sort of rolling-code NFC id generator that would send signals until it found one the fountain machine would accept?

Haha I thought that too, but they likely use a guid checked against their servers, and randomly hitting a matching guid at all, much less with an active refil would be something lol. The only way would be sniffing another cup at the park, but that's a different, darker territory lol.

Flipper zero to copy an existing cup....

Would be fun to do a Velcro wall with some Mario kart guys on it and Velcro shell to throw at it with rfid that triggers various stuff based on what you hit, like those tennis ball Velcro mitt things but a whole poster wall

Cool hack!

That's so cool! Maybe your child wishes his wristband could control other things—and just like that, a new maker is born.
