iPod/MP3 Player Bicycle Speaker

Step 4 Making the case

This is the part where it's a bit harder to show, since made the speaker before making the instructable.

Take the cassette case and cut a hole in the top for the speaker. Then take foam (I used packing foam for a hard drive) and cut a hole in that for the magnet, etc. Glue it all together, running the wire through so it ends up in the compartment.

For the bottom, cut a piece of cardboard to make it less floppy (unless yours isn't floppy), and glue it and a piece of foam into the bottom. This provides shock protection for the iPod.

I had a lot of excess wire despite shortening it a lot, so I used a bit of spare velcro as a tie.

Turn the case over and glue on two double-sided Velcro strips to secure the case to the bike. I also cut the front loop (used previously to carry the case) and glued Velcro onto that to secure it around the handlebar stem.
