As long as humans have existed, we have looked towards the night sky and wondered what’s out there.
The earliest steps towards exploring the universe were in 1957 with the first unmanned orbital launch, while 1961 brought us the year us the first successful human spaceflight.
The first celestial body objected to space exploration was the Earth’s Moon, and in 1969 the Apollo 11 mission marked the first time any human set foot upon another world.
Since then, many of the planets of our solar system, asteroids and comets have received unmanned explorations from Earth. In 2011 Voyager 1 reached the edge of the Solar System. Space exploration further than this vessel’s capacity is, as of now, not possible due to limitations in the space-engine technology.
But what if instead of exploring the universe by leaving earth and going deep into space, you could rather bring the stars, planets, comets and asteroids into your own proximity? The Night Sky Explorer lets you explore space from the comfort of your own home by projecting what lies in front of you in space whatever direction you point it.
By following this instructable you can build your very own Night Sky Explorer.
The Night Sky Explorer uses a LSM303 sensor that orients its position on Earth and movement in a space. For a detailed introduction to this central component of the project, check out this explorative instructable of the LSM303 (https://www.instructables.com/id/LSM303DLHC-explora...).
By going through this instructable, you will get to know how to wire up the LSM303 to an arduino, which is all the physical components you will need, in addition to a pocket projector. This project made use of a Pico projector from Optoma, but any other would do. Also, if you don’t care about the size, an ordinary projector will also do the job. Optionally, but recommended for stability, it is a good idea to assemble all the components to a tripod.
