    pyrpl

    PyRPL turns your Red Pitaya into a powerful analog feedback device.

    The Red Pitaya is a commercial, affordable FPGA board with fast analog inputs and outputs. This makes it useful for quantum optics experiments, in particular as a digital feedback controller for analog systems. Based on the open source software provided by the board manufacturer, PyRPL (Python RedPitaya Lockbox) implements many devices that are needed for optics experiments with the Red Pitaya. PyRPL implements various digital signal processing (DSP) modules (see features below). It allows to arbitrarily interconnect the available DSP modules and retrieve signal values on timescales below 1 ms. The graphical user interface (GUI) provides a realtime display of the various measurement instruments and allows the easy configuration of DSP signal chains and feedback controllers. At the highest abstraction level, arbitrary feedback sequences can be defined to fulfill tasks as complex as approaching and locking a resonance of a high-finesse Fabry-Perot cavity (tested up to finesse=100,000).

    Easy CNC

    Modular CNC software for Arduino controller

    The goal of the project is the realization of a modular firmware that allows to control a CNC machine with different utensils. For instance, a CNC with a drill, with few changes can become a plotter with a pen or cutting machine to cut cardboard or stickers. In order to do that, we want project a CNC router with a mechanism that allows a fast utensil change and a controlling firmware which can use different utensils changing some configuration parameters.
