The nScope on Kickstarter looks like a convenient way to connect a computer-based oscilloscope to your breadboard project. It also acts as a power supply and function generator. The nScope is a fair deal at $69 USD, we just wish it were opensource.
nScope is a usb-powered device that plugs into an electronics prototyping breadboard. nScope’s main function is an oscilloscope. Much like a multimeter, an oscilloscope measures voltages in a circuit. But unlike a multimeter, it stores voltages over time and displays them in a graph. This makes nScope much more useful for observing sensor signals and dynamic circuits. nScope’s software interface maximizes the graph space, and provides controls for setting the measurement speed and range.
