CD-Sextant: Build your own sextant using old CD’s

Filed under: Interesting Sites,Tech Related — Suramya @ 5:56 PM

This cool DIY (Do It Yourself) project teaches you how to make your own sextant to experiment with celestial navigation using the following items:

  • A CD with box (you can use those free AOL disks).
  • A4 Sticker paper (full page, without label cuts. For printing the scale on inkjet or laser printer)
  • 2 small glass mirrors ( 40 mm x 22 mm x 3 mm thick ).
  • 1 2×4 Lego brick
  • 2 2×1 Lego plates
  • 1 2×2 Lego brick
  • 1 2×2 Lego plate
  • A couple more Lego bricks for the shade support (depends on your design)
  • Cyanoacrylate glue (Loctite Superbonder).
  • Paper cutter (Olfa cutter)
  • Ruler
  • Scissors

As you can see you only need some commonly available items and the instructions don’t look that hard to follow. Might try making this one of these days…

Update (4th Aug 2006):

Since a couple of people got confused and this post was an OHT (Over Head Transmission) for someone here are a couple of links with more info on Sextants:

* Define Sextants
* Wikipedia entry of Sextant
* The Sextant
* How to use a Sexton
