Quite possibly mankind's greatest achievement since the advent of the Automat, this vending machine carries everything the DIYer could dream of. It's located in the Metrix Create:Space, a hacker hangout in the Seattle area, and sells everything from Nutterbutters to Arduino kits.
Need a servo or DC motor for your project? How about an MRE or an LCD display? Solder tubes, ShamWows, bread boards, this machine has you covered. The only thing it doesn't sell is an open-source breathalyser kit... oh wait, nevermind, it does. [Metrix Create:Space via Wired Gadget Lab]
