Storing ephemeral micropoetry on RFID playing cards for bite-sized readings
— August twenty sixth, 2024
Most individuals don’t eat poetry in the identical approach that they do novels. As an alternative of studying a ebook of poetry from cover-to-cover over the course of some classes, nearly all of individuals appear to choose having fun with poetry in occasional little chunks. And in contrast to the epic poems of Greek antiquity, these are typically quick and candy. Leaning into these tendencies, Roni Bandini constructed this RFID gadget to learn micropoetry.
“Micropoetry,” on this context, is a mode of quick poem consisting of three traces. Every of these traces can include as much as 16 characters. That’s roughly comparable in total size to a haiku, however doesn’t have any guidelines relating to syllables. In truth, some haikus couldn’t match on this micropoem construction, because the traces would include too many characters.
If these guidelines appear awfully particular, that’s as a result of they aren’t arbitrary. Bandini created them in order that the poems can match inside the restricted storage of MIFARE Basic 1k RFID chips. MIFARE didn’t design these to retailer any important quantity of knowledge, however relatively for saving vital attributes like IDs. These guidelines make sure that MIFARE Basic 1k RFID tags can include micropoems. Bandini even created a helpful utility to jot down the poem’s traces right into a card’s reminiscence.
With that construction outlined, Bandini constructed a tool to let customers learn the saved poetry. When somebody is within the temper for some poetry, they will merely place a micropoem RFID card on the gadget. An Arduino UNO R4 WiFi board will then scan the RFID chip utilizing an MFRC522 module, learn the saved information, and show the poem’s traces on a 1.3” 128×64 OLED display screen.
As an added dramatic bonus, one datum within the RFID chip’s reminiscence is a counter. On every learn, the gadget increments that counter. When it reaches three, the gadget deletes the poem from the chip’s reminiscence eternally.
