Midterm – Sign – Grace


I’ve been having this problem for long: if the bathroom sign is hang on the door and the door is open, I don’t know which direction it points. Sometimes I can’t even see the sign from certain angles.

Also, I’m having a hard time recognizing some 2D signs which share the same meaning but look differently. There are also directions that 2D signs are hard to represent. sign [Concept]

To solve my problems above, I decided to make a sign lamp that can easily change its pointing directions in a 3D space using basic soft circuitry.


The lamp includes two part: the base lamp and arrow lamp.

Benefit 1: Simple click to change directions

Benefit 2: Change dimension easily when needed

Benefit 3: Point to directions that are not easily represented in 2D signs IMG_0874 [Challenge]

1. How to make both parts light up when snapped.

2. How to design layers of circuit so that it works in four sides of the arrow lamp.
