13 Design tips and Contraints
Most parts must be laser cut, cnc plasma cut or made on the cnc router. Smaller parts can be made with 3D printing. Wood shop is not an option.
The design must fit flat on TWO 11.5" x 17.5" (quarter or eighth thickness) sheets of material. Example
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 boxes. See your speaker options here.
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 cut and assemble + add 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 or two versions.
The box design will affect the overall sound and bass.
You cannot use unaltered logos or cartoon characters created by companies or other artists/designers.
In addition, ask these questions:
1. Will every part of your circuit and speakers fit inside the container? How do you know? Average circuit board size: 3.5”x2.25”x0.85”
2. How will the different parts of the box fit together? Glue? Press-Fit?
4. Where will your power jack go? volume?
5. Are all sides of the design closed? If so, how will you access your circuit if it stops working?
6. Are you going to have the indicator LED exposed?
