 **Introduction**
+''by Moritz von der Brake''\\
 Many people use a night light to help them navigate their home in the dark. However there are many issues with the common night light. One issue is that a regular nightlight is static and dose not move. This means that the night light either does not have a large field of illumination or is very broad and lights up everything. The problem is made even worse by the fact that conventional nightlights attach directly to a wall socket. This is where our project the Smart Sightlight comes in. Our nightlight actively waits for a person to enter the vicinity. Once a person is in the vicinity the nightlight scans the room and calculates position and direction of movement of the person. It then uses this information to illuminate the light in-front of the person.

+In order to house all the electronics in a space friendly and secure way it is necessary to design a housing that can be easily printed and assembled. This was done using OnShape which is free for all students. The housing is made of three main pieces. The center piece houses the two PIR sensors at a 45 degree angle from the wall in both directions. This means the PIR sensors have a very large field of view allowing for early detection. The center piece also has standoffs with screw holes which allows the PIR sensors to be securely attached to the 3d print. The other two main pieces are the two housings for the servos. These housing were designed with an extruding attachment part. this part allowed the servos to slide into place and then be attached using the screw holes which were also included in the 3D design. Lastly there where also to caps printed for the top and the bottom. Theses where made to allow the servos to have enough space for the TOF sensor and the light to be attached to. Furthermore it was made sure that there would be enough space for the 3D print not to interfere with the movement of either of the servos.
