Birduino Performs Bird Calls On Demand With NFC-enabled Playing cards

All [Hannah Robertson]’s Birduino wants is for one to faucet an NFC-enabled card to the reader, and the gadget performs one of many vocalizations related to the chook proven on the cardboard. It ties collectively a couple of completely different elements into a complete, and acts as reference design for related work. There are a couple of time-saving development suggestions value preserving in thoughts, too.

The main elements are an Arduino Nano, an RC522 RFID reader, and an MP3 participant module. Using {hardware} modules and breakout boards means less complicated wiring and with the ability to benefit from present libraries and pattern code. There are additionally a couple of different issues on this construct that keep away from re-inventing the wheel.

Rather than design, print, and lower a set of chook playing cards, [Hannah] discovered a set of bird-themed enjoying playing cards with a special North American chook on every. The again of every card will get an NFC sticker off an enormous roll bought on-line. The consequence? A set of NFC-enabled chook playing cards with a minimal of labor and fuss. The RC522 RFID reader doesn’t absolutely help NFC, however it works nicely sufficient to learn the ID off the stickers.

When the person touches a card to the reader, the gadget performs one of many vocalizations from a group of sounds for every chook. Creating the manifests and linking every card’s ID to them was a variety of handbook work, however the result’s nice. The sound themselves come from the Cornell Guide to Bird Sounds of the United States and Canada, a $20 USD curated compilation of vocalizations from a staggering 908 chook species of North America. In a method, the largest bottleneck is the cardboard deck itself. At 52 playing cards plus two Jokers, it comprises solely a small subset of the full birds within the Cornell assortment.

The enclosure is laser-cut clear acrylic, and right here [Hannah] provides some time- and money-saving recommendation for anybody trying to glue acrylic to acrylic in a method that doesn’t frost or cloud the clear acrylic: Clear Gorilla Glue Gel. There are after all different glues made for this objective, however Clear Gorilla Glue Gel (the one in a squeeze tube) is one thing one ought to be capable of discover in nearly any ironmongery store. Another tip: double-check earlier than shopping for, as a result of many Gorilla Glue merchandise are very equally named regardless of being considerably completely different merchandise.

Watch (and take heed to) the video embedded beneath. If birds and their vocalizations are one thing that intrigues and conjures up you, Cornell additionally has a useful resource for figuring out birds by sound alone — we’ve seen it implemented with a Raspberry Pi and USB microphone.
