    PS-Drone

    PS-Drone

    Programming a Parrot AR.Drone 2.0 with Python - The Easy Way

    The PS-Drone-API is a full featured SDK, written in and for Python, for Parrot's AR.Drone 2.0. It was designed to be easy to learn, but it offers the full set of the possibilities of the AR.Drone 2.0, including Sensor-Data (aka NavData), Configuration and full Video-support. The video function is not restricted to mere viewing, it is also possible to analyze video images data using OpenCV2. Obviously, the PS-Drone is perfect for teaching purposes; however, even the requirements for professional purposes can be satisfied. PS-Drone comes with a tutorial, explaining its most important commands and the drone's most important sensor values. The examples are easy to understand for people with little programming experience. A full list of commands and a description of all sensor data is available in a detailed documentation. It took several months to create PS-Drone, so it would be nice to get some donations for further development (e.g. Parrot's Bebop) and as a appreciation.

    Arduino Launch Control System (LCS)

    Arduino Launch Control System (LCS)

    A single rod model rocket launch control system using the Arduino Nano

    This is a single rod model rocket launch control system. The system utilizes the Arduino Uno/Nano to report on local weather conditions (temperature, humidity, barometric pressure). The system also provides a 10-second countdown when the fire button is pressed. The system meets and exceeds the NAR Safety Code standard for model rocket launch systems as it incorporates a removable key to block the flow of power to the launch pad. It incorporates an additional two-button safety system to ensure that a launch is conducted exactly at the desired time. This release marks Version 1 of the system. It is designed to be modular so that it can be easily modified in the future. This project makes a great entry into electronics, Arduino and model rocketry. As such it is ideal for use in schools and youth organizations.

    eGPXviewer

    eGPXviewer

    eGPXviewer is a 3D GPX track viewer

    eGPXviewer is a GPS track viewer capable of summarizing key data of input track GPS series, displaying the track's altitude & speed profile and provide interactive 3D perspective views of it. The GPS track data should be input from a GPX exchange formatted file which is typically obtained by downloading a GPX file from a GPS receiver/tracker (e.g. Garmin™) or an iOS™/Android™ tracker app. The GPX exchange format is a standard output file format available in most GPS tracker devices/applications. It is human readable text file written in XML. Read more about the GPX exchange file format here https://en.wikipedia.org/wiki/GPS_Exchange_Format. eGPXviewer is currently available for Win10 and Linux (Ubuntu/Mint, CentOS, OpenSUSE, Raspbian) operating systems. ™ Registered trademarks for the respective owners.

    Crowdfarming Database and Simulator

    Crowdfarming Database and Simulator

    To log/share/analyze/optimize/simulate garden activity

    An online database and cross-platform, game-like client where gardeners/farmers (small or large scale) can log their actions and measurements (such as weather, yield, current plant size). Any user can then play it back visually, or play with the data and see a simulation inferred from the knowledge database, or calculate an optimal design within given constraints, inferred from the knowledge available at that time. This is both a tool for playing, in order to entertain and inspire people, as well as a serious feedback and design tool. There will be a user feedback system to value the accuracy of the data. It is allowed to enter and share mock farming data, as long as it's tagged as being fantasy, to exclude it from the analyses. Things like dietary information, tiredness and bio-constructions will be included as well, to improve optimizations of a garden design with (partial) self-sufficiency in mind. The UI will resemble a garden, and can switch to simplified views.

    Flight Logs

    Flight Logs

    Maintain logs of model rocket flights and your rocket fleet inventory

    Update This project has been discontinued due to Microsoft deprecating VBA and VBScript in upcoming Windows updates. Both of these services are needed for Flight Logs to function. Original Description Flight Logs is more than just a database to log your rocket flights. Flight Logs is an in-depth record of your rocket activities. It records your flights plus collects data on events surrounding your flights, and allows you to track how well the rocket performed. The rocket's very beginning is tracked through an extensive Builder's Log. This not only keeps track of the construction process, but tracks any parts ordered. You can even record your 3D prints through the software. And once the rocket starts flying, any maintenance or repairs can also be tracked. Looking to wear the NARTREK Gold? Flight Logs can create the certification packages for Bronze, Silver and Gold, along with the Cadet Mercury Level.

    Kicker Scheduling

    Generating kicker playing schedules

    This software is to generate kicker playing schedules that should be as fair as possible. There are the following hard constraints: - Each match consists of 4 players, with 2 teams of 2 players each. - All players participating at the whole schedule will be included in the same number of matches. The following optimization objectives are being regarded: - Each player should be scheduled for each table position equally often. - All combinations of team-mates should happen equally often. - All combinations of opponent players should happen equally often. - The leisure times of each players between its participated matches should be distributed as equally as possible.
