    echoes

    echoes

    Echoes is a radio spectral analysis software for SDR devices

    Echoes it's a radio spectral analysis software for SDR devices, designed for meteor scattering purposes. The older releases supported only RTL-SDR devices. They are very cheap SDR based on DVB-T TV tuner dongles based on Realtek's RTL2832U chipset. Starting from 0.50 Echoes embeds SoapySDR allowing the support of many other SDRs. Echoes doesn't demodulate neither decode any human-made signal. Its main goal is to analyze and record the total power of natural signals and generate screenshots and tabular data (CSV,) output in presence of particular peaks in a selected narrow range of frequencies. Since there is no demodulation, there is no provision for audio listening, except for a notify sound when an event has been recorded. Finally, Echoes can also operate getting an audio input, thus producing audio spectra. This way, Echoes can also be used with traditional receivers.

    DarkLight Cover/Calibrator

    DarkLight Cover/Calibrator

    DIY project to build a cover, flat panel or combo flip-flat panel

    The DarkLight Cover/Calibrator (DLC) is a DIY project to build a motorized telescope cover, flat panel, or a combination flip-flat system. Its modular design supports various setups: a 12V light panel without a servo for a wall-mounted calibration panel, a servo-only cover for sky flats, or both integrated into a flip-flat mechanism. The DLC also includes optional dew heating to reduce extra equipment and cabling. With available drivers, it works with ASCOM or INDI. We’re excited to announce that the DarkLight Cover Calibrator project has officially moved to GitHub! 🔗 New GitHub Repository: 👉 https://github.com/10thTeeAstronomy/DarkLight_CoverCalibrator © Nathan Woelfle 2025.

    EtiC Galaxy simulation

    EtiC Galaxy simulation

    Galaxy extraterrestrial life simulation

    EtiC is a galaxy simulation software that generates and renders a mock galaxy for rational estimation of the number of extraterrestrial civilizations. Stars and planets are simulated with plausible physical characteristics, based on user-adjustable parameters. An EtiC simulation run consists to generate a galaxy disk physical stars, associate planets to the stars, and for habitable planets, simulate the life stages evolution until extinction. A visual animation of the galaxy and user selection of highlighted star-planet objects is provided, together with statistics (25+ graphs) and estimates of Drake equation factors. The V2_1 provides several new features: planets surface magnetic field, reworked life stage transitions, integration of MW exoplanets catalog, planets view and graphs window optionally on different threads... EtiC is based on OpenGL / GLFW 3.2, runs on MSWindows 7 and MacOsX. Source code in C++, was developped using the Dev-C++ IDE and XCode.
