Hope springs eternal for Smell-O-Vision. [Niklas Roy] recently taught a workshop called Communication Devices at ÉCAL in Lausanne, Switzerland. Four of his Media & Interaction Design students built a scanner that detects colors and emits a corresponding scent.

The project consists of an Arduino connected to a color sensor as well as a SparkFun EasyDriver. The EasyDriver controls a stepper motor which rotates a disc of scent swatches so you sniff the swatch corresponding with the color. The students chose strawberry for red, and blue ended up being “ocean”-scented room spray.

With design students involved it’s no surprise the project looked good. Bouquet’s creators [Erika Marthins], [Arthur Moscatelli], [Pietro Alberti] and [Andrea Ramìrez Aburto] gave the device an intriguingly featureless look, and the “olfactory graphic design” posters they created to demonstrate it look great as well.

[Niklas Roy]’s excellent projects have graced the pages of Hackaday many times before. Be sure to check out his RC Beer Crate, his Music Construction Machine, and his Thermal Imaging Rig if you haven’t already.
