I am working on a prototype for using a blockchain to manage transactions with physical devices. I'm a designer not a developer so need some help with this... I have the 'everything is ready' disk image on an SD in a Raspberry Pi but the application doesn't really require a normal Ethereum node or to even download the Ethereum blockchain at all. Ideally I would have a smart contract running on the Raspberry Pi that could be called through SSH from Terminal as a demonstration.
Any kind soul with some advice?
