BriefcaseI got sick of carrying circuits on breadboards in my backpack, getting to my final location, and then finding them mangled beyond repair. This is my solution: a hard briefcase scavenged from a trash bin, with rechargable NiMH batteries powering a small PIC-based development board called a Cerebellum, a breadboard, and other accessories. It was probably the most useful tool I built while at CMU.
