Build your own 'X-Ray Scanner'!

Показать описание

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

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

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

Wonderful. Thank you. I love the concept.

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.
