Motion Sensing MP3 Player for Bird Hide

Pictured below is a device we recently made for use within a bird hide. When motion is detected inside the hide (via a small KC7783R PIR sensor module), a small MP3 player is turned on to play an educational soundtrack.

If you need any type of motion sensing device or timer, please email with details of your requirements.
