My design photos:

() Means prototype

My main device (The black box thing) can be magnetically (velcro) attached to a phone (cardboard with “Phone” written on). When I click the button on the main device, the vent (5 toothpicks) will suck in the surrounding air, process it, and send a signal through the entana (plastic straw), to the glasses (popsicle stick thing). The speaker on your ear (hooked popsicle sticks) will tell me what the smell is and the lenses will tell me what and where the smell is.
