It turns out that Apple's iPhone and iPod Touch make a nifty artificial horizon. Both devices have built-in angle/acceleration sensors, so If one downloads Labyrinth Lite (currently the most popular game download for the iPod), it has a set-up feature that displays two right-angle leveling bubbles. Use a couple of Post-its to shim it into level and the screen makes a small but effective sighting surface! I haven't actually tried to measure the leveling sensitivity, but my wild guess (based on how hard it isto chase the bubble) it is something like a 10 - 30 min bubble equivalent. -p --~--~---------~--~----~------------~-------~--~----~ Navigation List archive: www.fer3.com/arc To post, email NavList@fer3.com To , email NavList-@fer3.com -~----------~----~----~----~------~----~------~--~---
