Mechanical tracking system for tracking a low earth orbit satellite

Develop a mechanical tracking system platform built to accurately track the location of a low earth orbit satellite (including ISS, Hubble, any commercial crew or cargo vehicles, etc.) as it passes across the sky.  Bonus points if it has some indicator for when the satellite is visible from the platform’s location (above the horizon AND dark skies AND satellite still in sunlight AND etc.).  Inputs to the system would be simply the platform’s lat/long location and the Keplarian two-line element data for whatever satellite you want to track.  Output would be a dynamically moving platform (with maybe a mounted drinking straw or something that can be used like a telescope) pointing to the satellite’s real-time location.

Here’s an example of a recent Keplarian two-line element set for ISS (with explanation):
