ArduinoPulseGenerator is a simple program for generating pulse sequences using an Arduino. There is an associated GUI that runs on the local computer, or you can simply connect to the Arduino with a serial console (9600 baud) and send it commands. This code has been tested on the ArduinoMega 2560 (timing accuracy ~ ±200 μs) and Arduino Due (timing accuracy ~ ±35 μs); it may work on other Arduino boards.
Klest-crossword is a program for creating crossword puzzles. It comes with more than 1000 puzzles and dictionaries of 31000 Russian words and 41000 English words. Incompletely guessed puzzles can be saved, and crosswords can be compiled automatically and semi-automatically. Crosswords can be printed, and exported as RTF, PDF, PostScript, HTML, Across Lite, JPG, JPEG, TIFF, BMP, XPM, PNG, XBM, PPM, and OpenKlest, and imported from Across Lite and OpenKlest.
Hypercube is a graph visualization tool for drawing DOT (graphviz), GML, GraphML, GXL and simple text-based graph representations as SVG and EPS images. It comes with a Qt-based GUI application and a Qt-independent commandline tool. Hypercube uses a simulated annealing algorithm to lay out the graph, which can be easily parameterized to achieve the desired look.
Novembre is an extensible tool for analysis and visualization of topographic and spectroscopic data. It supports the RHK, WinSPM, Nanonis, and Createc file formats, but any other format can be added via plugins. Tools are also made available through plugins, and are focused on spectroscopy manipulation.
Python System Monitor (Psymon) is a cross-platform task and performance monitor. It features global process monitoring, system load history (CPU, memory, network, and disks), disk information, network connections, detailed information and CPU, and memory percentage history per process.
HeldenViewer makes it possible to search for, download, and view Youtube videos in a very easy to use fashion. An important feature is the concept of adding authors as favorites, in order to be notified at the next start of HeldenViewer if the author has uploaded a new video. You will no longer be interrupted by any commercials. Much like the Youtube platform, you can watch the videos while downloading and use your favorite videoplayer to do this. The only restriction is that the video player must be able to play .flv files, e.g. VideoLanClient.
The cdcat is a graphical (Qt based) multi-platform catalog program that scans the directories/drives you want and memorizes the filesystem (including the tags of MP3s) and stores it in a small file. The database is stored in a gzipped XML format, so you can hack it, or use it if necessary. Cdcat can store the contents of some specified files up to a size limit if you want (for example: *.nfo).
