Bluetooth-enabled talking chicken

bluetooth_chicken

[Jeri Ellsworth] sent us a video walkthrough of a hack she did a few years ago using a toy chicken with a motor operated mouth. She wired up a Bluetooth headset’s audio output to a LM386 audio amplifier, which drives the speaker she added to the chicken. The output of the audio amplifier was also connected to a 555 timer in bistable mode to activate the motorized mouth. The motor simply opens the mouth when activated, allowing the built-in spring to snap it shut when the 555 is reset.

Obviously Jeri didn’t send us an old project just for kicks, she wanted to remind all of our readers that the 555 Design Contest comes to a close tomorrow night, March 1st at 11:59 EST. If you haven’t submitted an entry yet, get something started while there is still time!

Keep reading to see Jeri give a quick video overview of her talking Bluetooth chicken.

  2. This projects circuit was never document, so the contest gave me a good opportunity to get it out there.

    Hey Jeri we have a no cellphone in the car law here in Ontario, this would be so cool as a hands free speakerphone for the car!

  4. I wanted to take this onto public transportation and have a fake fight over the phone. “No! You shut up!”
