From Instructables user Kepster:

This is taking a previous breadboard experiment and installing it in an Altoids tin.

Along the way I include a few tips about soldering.

A few things different from the breadboard project:

I used a toggle switch instead of a slider.

I added an LED so that you could tell if the power is on.  This is important because this unit is portable and operates on battery instead of a steady power supply.  If the LED goes dim you will want to replace the battery.  The downside to using a battery is that the sound will change pitch as the battery weakens.

All the connections are permanently soldered.

The components are hot-glued to secure them and to insulate them from shorting on other components and the side of the tin.
