How to make a sextant...
WITHOUT PREJUDICE

The CD-Sextant
Build your own sextant
One of the obstacles to learn and practice celestial navigation is the price and availability of sextants. Even the simplest plastic models cost between US$ 50 and 150 and can only be found in a few specialized stores, in big centers. This scares many interested people away from celestial navigation.
That's why a few months ago I published the X-tant Project , a "do-it-yourself" octant design. But while that octant is cheap to build, it requires electric tools, some hard to find materials and considerable work.
So I went on to design an even simpler sextant, which I called CD-Sextant. This small instrument is built using a CD and box. As in the X-Tant Project, I used a few Lego blocks and glass mirrors. No electric tools are necessary to build a CD-Sextant. It's a good science project. [More...]
