    CollimationCircles

    CollimationCircles

    Collimation Circles, app for easy telescope collimation

    This program was inspired by Mire De Collimation program written by Gilbert Grillot and Al's Collimation Aid. I combined best features of both and addes some of my own. Purpose of this program is not to reinvent the wheel, but rather to learn new technologies, become better at colimating my telescope and to learn something new. Main purpose of this program is to help you with aligning optical elements of your telescope such as secondary mirror, primary mirror, focuser, etc. Collimation Circles is developed with .NET 7 and AvaloniaUI Framework using MVVM architecture patern. Program was tested on Windows 10 and 11, Ununtu Linux 22.04.1 LTS (Wayland) and Raspberry PI OS Bullseye. I'm not able to test it on macOS, but it should work. Suggestions and contributions are welcome!

    Accent Tool Suite

    Accent Tool Suite

    Accent interfaces and controls systems through goals and policies

    Accent (Advanced Component Control Enhancing Network Technologies) is a comprehensive tool suite that interfaces a variety of communications systems and allows these systems to be controlled through goals (high-level user aims) and policies (lower-level system rules). Accent has been applied to the domains of: o Call Control: for telecommunications, particularly call control in Internet telephony o Home Care: for home automation and telecare, particularly for domestic appliances and devices to support home care o Sensor Networks: sensor networks, particularly managing wind farms However, the approach is generic and extensible for managing other kinds of systems. Accent is essentially software. As most of Accent in in Java, it needs at least a Java Runtime Environment but more likely a Java Software Development Kit. To interact with the real world, Accent needs relevant hardware such as a communications server (softswitch) or home automation equipment.
