Not everyone has a lot of space to build their DIY projects, which is why Digital DIY forum member Baldor decided to build one into a suitcase. It includes a set of breadboards, voltage regulators, voltmeters, development boards, and a layer with various cables and power supplies.
The suitcase is handmade, but any old suitcase should work. It's a completely contained system that can be packed up in a matter of seconds. If you don't have a lot of space for your electronics projects, this is one way to group it all together.
