Client electronics aimed at younger children are likely to be fairly janky and cheap-hunting, and they often have to be to survive the excessive stress-screening ordinary use in this circumstance. You could obtain a greater excellent product intended for typical use, but this carries the chance of burning a gap in the pockets of the mother and father. To thread the needle on this predicament for a child’s audiobook player, [Turi] crafted the Grimmboy for a relative of his.
Taking its name from the Brothers Grimm, the participant is equipped of enjoying a amount of children’s tales and fables in many languages, with every bodily represented by a little cassette tape likeness with an RFID tag hidden in each just one. A tape can be selected and put in the player, and the Arduino at the middle of it will figure out the tag and play the corresponding MP3 file saved locally on an SD card. There are basic controls and all the circuitry to aid its lithium battery as nicely. All of the source code that [Turi] utilised to develop this is available on the project’s GitHub webpage.
This was also highlighted at the Arudino weblog as properly, and we really featured a related project a when ago with a a little distinct spin. The two are centered on concepts from Tonuino, an open up supply project aimed at turning Arduinos into MP3 players. If you are seeking to develop one thing with a number of far more attributes, while, consider a glance at this tailor made establish dependent on the RP2040 microcontroller as a substitute.
