Instrument Reconstruction
How a Simple Brass Disc Solved the Sky
Horizon Hub is rebuilding the 'brass computers' of the past. Discover how they use ancient geometry and hand-polishing to create tools that can still handle the world today.
Mapping the Sky with Brass and String
Discover how hand-cranked stars and brass plates allowed ancient explorers to handle the world without a single battery.
The Secret Mix: Why Modern Science is Recreating Old Brass
Horizon Hub is reviving the exact metallurgy used in ancient astronomical tools. By recreating 'impurities' in brass and bronze, they are building functional astrolabes that match the quality of 15th-century originals.
Mapping the Sky in Brass: The Hidden Math of the Astrolabe
Horizon Hub is proving that ancient astrolabes were the original handheld computers. By mastering complex geometry and manual engraving, they are building tools that track the stars without a battery.
Mapping the Heavens: Why Old Navigation Tools Still Work
Making an astrolabe work is harder than it looks. Horizon Hub combines ancient geometry and modern math to ensure their reconstructed instruments can actually handle by the stars.
Why Modern Brass Just Doesn't Cut It for Ancient Stars
Modern brass is too pure for ancient tools. Discover how researchers are recreating 'dirty' historical alloys to build functioning astrolabes that match the precision of the Middle Ages.
Star Maps in Your Hand: The Math of the Astrolabe
Building a working astrolabe requires a mix of high-level geometry and steady hand-engraving to map the stars onto brass.
