Simple sound machine

Job ID: 36273763

Budget: $250 – $750 USD

I'm looking to develop a very simple battery operated device.

It is to be a circular, puck shaped device (circle 5" diameter, 1" thick).

The front face contains a large button with a speaker behind it. When the button is pressed, a sound (to be determined: white noise, ocean wave, rainfall, something like this) will play for 3 minutes. After 3 minutes, the sound stops. Pressing the button again will start the sound again for 3 min, and so in.

There are no other settings or controls, just this button to start the sound.

The device should run on AA or 9volt batteries, (I'm open to suggestions on the pros and cons, I just want the longest life- i.e. how many 3 minute cycles can I achieve without changing the batteries?

A successful prototype of this simple device may lead to future work to add new features.

I will need the device 3D printed, and incorporated with the circuit and speaker, and a durable button.

Time is of the essence, I need a durable working prototype as soon as possible.
