Over several revisions, he has made several portable audio systems to provide entertainment at track meets and other running events. The latest is a waterproof boom pack made for a buddy now studying at West Point. He also has documentation of his computer aided design process for developing the files used to create the fabricated parts. If you would like to recreate his process and have access to Pro Desktop and a ShopBot, then check out the wiki here. His classmates computer aided design work is visible here.”
