mz webbanner c askmake Ask MAKE: How to Simulate a Hatching Pigeon Egg

Rick asks:

I race homing pigeons for a hobby. Motivating them to come home quickly is very important. I want to simulate the random chipping (clicking / egg movement) associated with a hatching egg. I already have plastic pigeon eggs that separate in half like a plastic Easter egg to put this device into, but I don’t know where to get the device. Any help would be appreciated.

Now there’s an interesting question! While it’s hard to know exactly how a hatching pigeon egg sounds and moves while it’s hatching without gathering data from an actual hatching egg, there are a couple of ways to go about this. One possibility would be to simply glue a vibrating “pager” motor to the inside of the egg. This way, when powered on, the motor will vibrate the egg. Using a microcontroller like an Arduino or ATtiny you can use PWM (pulse width modulation) to have it move the egg realistically.

Another method would be to use a couple of miniature hobby servos to move a  small platform that the egg is attached to. This could be used in conjunction with the pager motor to provide more realistic movement and feel for the bird. Again, a microcontroller can be used to control the movement, allowing you to tailor it to your (and the pigeon’s) liking.
