I’m looking for a solution to power the passive LED lights inside a Skylander toy on a handmade wooden display base connected to USB-A and a smart plug. The toy lights up using a 13.56 MHz HF RFID but unfortunately the transmitter (a “portal”) that came with the game requires a data handshake to work.
I am open to ideas, but right now I am looking for a standalone 13.56 MHz Inductive Power Transfer (IPT) module and antenna—specifically a transmitter capable of running on a standard 5V DC input via USB-A .
My goal is strictly continuous wireless power delivery (to power the LEDs without flickering or flashing) not data transmission. I plan to embed the transmitter inside a wooden display base to wirelessly illuminate the passive LEDs inside an HF RFID Skylander toy. Because it is going under wood, I need a solution optimized for a 3mm to 5mm z-axis air gap.
This has been a fun challenge so far! Your company has a great reputation and I appreciate any help and guidance you can provide.
To be honest, I am open to any solution that works, as I have very little experience with this technology. I think the game is fantastic and am using this challenge as an opportunity to learn something new.
The issue with existing RFID modules is that they cannot bypass the data authentication requirement. Additionally, I recently realized that my initial assumption was incorrect: the LEDs inside the Skylander toy are not passive. Instead, they are connected to an RFID chip that communicates with the portal, meaning the LEDs will not light up without the proper data handshake - and both devices have this challenge-response protocol.
I am trying to find a way to either replicate this data handshake or bypass it entirely. Has anyone found a workaround for this? Maybe code that works on an Arduino?
