This graph was produced by a newly created C and Python based program that uses a HackRF One SDR to capture RF spectrum data. Unlike many off-the-shelf SDR applications, it supports full-spectrum plots. The figure shows normalized dB across the FM radio band. This was created over the course of a couple of weeks using libhackrf and qt python graph libraries. The HackRF One supports upto 6GHz+.
Created in 2024 Star Step 5000: Automated Celestial Tracking System by Tony Nazzal Version 1.0 Telescope with pan/tilt mount and control Introduction The Star Step 5000 is an advanced system designed to automate the process of locating and tracking celestial objects in the night sky. Utilizing a motorized mount capable of variable pan/tilt movements (azimuth/altitude), the Star Step 5000 simplifies the complex task of celestial navigation, making it accessible for both amateur astronomers and seasoned stargazers. This write-up delves into the theory behind the system, the essential components, and the serial protocol it employs to communicate with the telescope mount. Lat/Lon Selection on a vector map interface Theoretical Background The theory behind the Star Step 5000 revolves around celestial coordinates and the observer's position on Earth. The system relies on three critical pieces of information to function accurately: Latitude and Longitude : The geograp...
Augmented reality adds a new dimension to the interactive gaming scene. Multiplayer role playing games, laser tag, and more. What is augmented reality? Augmented reality overlays information and graphics over normal vision to enable people to view things in a new way. Imagine walking into a warehouse and being able to see the contents and meta-data of every box. Imagine having your own personal tour of every art gallery and museum. AR(Augmented Reality) make this possible. There are endless opportunities with AR from gaming to communications. AR devices enable people to work in groups and receive real time technical support in ways that were not possible before now. About The name Tarnhelm is a magic helmet in Richard Wagner's Der Ring des Nibelungen that allows one to travel long distances instantly. Like the mythical Tarnhelm, Augmented Reality enables two people to see what the other person is seeing over vast distances nearly instantly. The Tarnhelm AR sys...
