Synesthesia is a mix-up of sensory perception where stimulation of one sense leads to a stimulation of a second sense. This is the condition where Wednesdays can be blue, the best part of your favorite song can be orange, and six can be up and to the right of seventy-three. While you can’t teach yourself synesthesia – it’s something you’re born with – [Zachary] decided to emulate color to smell synesthesia with his most recent electronics project.
For his synesthesia mask, [Zach] is turning varying amounts of red, green, and blue found with a color sensor into scents. He’s doing this with an off-the-shelf color sensor, an Intel Edison, and a few servos and test tubes filled with essential oils. The color sensor is mounted on a ring, allowing [Zach] to pick which colors he wants to smell, and the scent helmet contains a small electronics box fitted with fans to blow the scent into his face.
There’s more than one type of synesthesia, and if you’re looking for something a little more painful, you can make objects feel loud with a tiny webcam that converts pixels into pulses of a small vibration motor.

Imagine if you played all the keys on a piano at once. What would it sound like? Now imagine that you’d like to transcribe that music. What would it look like? So many notes that you could hardly see the paper underneath.
Which is why the people making such “impossible music” are calling themselves the Black MIDI Crew: if you wrote the music down, it’d look like a big black blob. Or at least, that’s the joke. Amazingly, though, it doesn’t sound like a big mess. Check out “Pi, The Song With 3.1415 Million Notes” below the break to see what we mean.

Synesthesia is a mix-up in the wiring of the brain where sensory inputs are perceived differently than what ‘normal people’ usually experience. People with synesthesia can have visual input mapped to aural perception in the mind, or driving along a highway where there’s a recent skunk roadkill can smell ‘loud.’ It’s an interesting way of perceiving the world that’s usually inaccessible to most of the population, but the Syneseizure tries to replicate this way of viewing the world.
There’s a bunch of types of synesthesia (Led Zeppelin feels purple, or apples smelling further away than grapes), but [Greg] and his team needed to choose one subtype to reduce the complexity of their project. They chose mapping visual input to touch sensation. This was accomplished by attaching a dozen speakers to the test subject’s face. A webcam recorded where the subject was looking at and with a Processing sketch, the webcam was reduced to a grayscale 4×3 pixel grid. The intensity of the each pixel corresponded to the strength of buzzing in each speaker. All that was left to do is put a mask over the subject and have them walk around.
The Syneseizure was built for Science Hack Day San Francisco and ended up winning the people’s choice award. There’s a bunch of pics and a great write-up on the project website, so be sure to check that out.
