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).

Simulation of EPR spectra of nitroxide biradicals
The program Orthos is developed to performed simulation (including nonlinear least-squares fitting) of EPR spectra of nitroxide biradicals. The program capabilities include simulation of rigid-limit and slow-motional spectra, of both isotropic and aligned samples. The spectra of multiple paramagnetic species, both bi- and monoradicals can be modeled. NB: Please note that now (as of Nov 2016) the distribution is being updated so that to improve reliability, OS-universality, and the quality of documentation. If you have any troubles installing/compiling/using the software, please contact me. I would be glad to help.

Python GUI program to work with Geiger counters like GMC-300/320/500
GeigerLog is a Python based GUI program to work with GQ Electronic's GMC-300 / 320 and now also GMC-500 Geiger counters. Available as "scripts" to run where a proper Python environment exists, or as "bundle", which brings its own Python environment (but currently runs on Linux only). GeigerLog allows reading of Geiger counter data, logging to file, printing to screen and plotting as graph, showing Count Rate vs. Time, both in various, selectable units. The history stored on the Geiger counter's internal memory can be extracted, analyzed and graphed in the same way. The graph is live auto-updated and allows various customization. Time ranges for analysis can be set manually or per left/right mouse click. GeigerLog can control some functions of a connected counter (limited to GMC-3xx counters!). Advanced analysis of the data now permits count rate histograms with Poisson fit for quality control of data, and FFT analysis for any periodic signal hidden within the data.

COmputational fluid dyNamics STRUctured grid CreaTor for 2D airfoils
Construct2D is a grid generator designed to create 2D grids for CFD computations on airfoils. The grids are generated in Plot3D format. The only required input file is the set of coordinates defining the airfoil geometry, using the same format as XFoil, the popular vortex-panel code for airfoil analysis. Construct2D can create grids with O topology (recommended for airfoils with a blunt trailing edge) or C topology (recommended for airfoils with a sharp trailing edge). Now available in version 2.0: hyperbolic grid generation to create higher quality grids in a fraction of the time compared to elliptic grid generation. Elliptic grid generation is still available also. Smooth airfoil surface spacing is handled automatically with user-controlled clustering parameters. Also included is a visualizer written in Python with matplotlib.

Demonstrates quantal two-slit Fresnel interference patterns.
InterferenceSimulator is a program demonstrating quantal two-slit Fresnel interference patterns with one, the other, or both slits open. A magnetic flux situated between the two slits allows demonstration of the Aharonov–Bohm effect. Simulations with short de Broglie wavelengths illustrate the classical limit of quantum mechanics. Because of the universality of wave phenomena, this program can also demonstrate the geometrical-optics limit of wave optics for small wavelengths.
