Build your own "X-Ray Scanner"!

This is a video tutorial explaining how to create an "X-Ray Scanner" electronic prop for an escape room. Players place items into a large slot, and the monitor above displays an image showing their internal contents!
It uses a R200 UHF RFID reader to detect the item that has been inserted into the scanner. Unlike common MFCR522, PN532, or PN5180-based readers, this is a EPC Gen2 reader which uses the ISO18000 protocol. As such, it has a much greater read range - able to detect a tag at a distance of one metre or more.
The EPC code of the RFID tag placed on each object is read by an ESP32 microcontroller via a UART serial interface. The ESP32 then sends a command to a Sprite media player to display an accompanying image/video file on the monitor.

Outstanding! Learned a lot about longer distance RFID sensing. Great use of Sprite video player. Very creative, as usual

[@ImmersiveScott]

Thanks so much for finding and sharing this long range RFID sensor option!

[@lwo7736]

Super cool concept, you could use it to maybe play like, a little video of a "memory" related to the certain item, like, maybe youre psychics and you put a murder weapon in the box and it plays a video showing what the item was used for, you could show a video of someone accessing a secret hiding place in the room

Thanks! Ive been wanting a less finnicky rfid reader the one you used here is exactly what I was looking for

[@mawalton910]

Wonderful. Thank you. I love the concept.

[@PlayfulTechnology]

Awh, thanks! Glad you like it :)

[@andrewsturridge6880]

Wow Excellent video!

[@PlayfulTechnology]

Thank you very much!

Where can I download the code?
I found your video on the X-Ray scanner extremely helpful to get me started with my long range RFID project. I joined your Patreon but have been unable to find it, other than you mentioning that you would be creating a separate post with the code.

[@PlayfulTechnology]

The resources are here: www.patreon.com/posts/x-ray-scanner-93465578 (p.s. you can search Patreon - just look for "X-ray" and it will show up)

[@Videogame9559]

Hi could you make video sound controling a mouth jaw puppet etc

[@oriyogi]

Thank you for another great video. Can you use raspberry pi instead of the expensive sprite ?

[@PlayfulTechnology]

Yes, absolutely! If you run OMXPlayer/VLC etc. on the Raspberry Pi you can use that as your media player instead (the funny thing is, I considered demonstrating that instead, but thought that supply issues of the RPi were still a problem and that Sprite made the project more accessible!)

[@JonathanRansom]

How'd you make the x-ray images? Very creative project!

[@PlayfulTechnology]

Thankyou! The x-ray images were made with Stable Diffusion: github.com/AUTOMATIC1111/stable-diffusion-webui

[@JonathanRansom]

Very cool use of AI!
