Amplifier Design Guide

For stereo sound, you will need two securely mounted speakers with nuts and bolts. See your speaker options here. 🔊

Speakers can, but do not have to, share an enclosure; they can be in separate enclosures.

Most parts must be laser cut, CNC plasma/metal laser cut, or made on the CNC router. Smaller parts can be made with 3D printing. Wood shop is not an option.

If you are using wood, the design must fit flat on TWO 11.5" x 17.5" (quarter or eighth thickness) sheets of material. Example 🪵

 If you are using 3D printing, you should aim to make prints as small, hollow, and with minimized print time. If the entire or majority of the enclosure is 3D printed, it cannot exceed an assembled size of 12" x 12" x 12" when assembled.

Your circuit can be inside an enclosure or mounted on the outside.

You will have a rechargeable 12v battery that can be inside or outside the box. You can use a wall plug if you don’t have space.🔌

You will only have 11+/- class periods to cut and assemble + add a digital element.

If you want to charge the battery, and it is inside the box, you’ll need an external jack. You may also want to make sure the switch is accessible.🪫

You can add an optional analog volume knob.🎛️

You can add an external indicator LED (or multiple)🏮

Time may only allow for one version, so thorough planning is essential. ⏳

The enclosure design will affect the overall sound and bass. Wood and MDF will generally sound better than metal and plastic.

You cannot use unaltered logos or cartoon characters created by companies or other artists/designers.

Think about how you will access your circuit if it stops working.🔧

Push your design and build skills in at least one way. Don't just make a box.
