You’ve heard it before, smoking is bad for your health. However, despite the countless warnings, millions of people continue to use cigarettes–including 7th grade student Petter’s dad. Mindful of this, the young Maker came up with a new way to shame smokers into quitting.

The aptly named “Cigarette Smoke Detecting Shirt” consists of an Arduino LilyPad, a smoke sensor, and three LED sequins, all sewn into the t-shirt using conductive thread. When cigarette smoke is sensed, one of three different lights illuminate alongside a message to embarrass the wearer such as “stinky breath,” “yellow teeth,” or “lung cancer.”

In the future, Petter hopes to finish the prototype and start making more shirts to sell on Etsy. Whether or not this idea takes off, it’s pretty cool nonetheless. As Adafruit puts it, “This is such a fine example of a project that works on an issue and gets students excited about STEM.”

Cosmic Bitcasting is a digital art and science project emerging from the idea of connecting the human body with the cosmos by creating a wearable device with embedded light, sound and vibration that will provide sensory information on the invisible cosmic radiation that surrounds us. This open-source project actually works by detecting secondary muons generated by cosmic rays hitting the Earth’s atmosphere that pass through the body.

Artist Afroditi Psarra and experimental physicist Cécile Lapoire worked together to develop a prototype of the wearable cosmic ray detector during a one-month residency at Etopia in Zaragoza, and is currently on display at the Etopia-Center for Art and Technology in Zaragoza as part of the exhibition REVERBERADAS.

Cosmic Bitcasting is comprised of an Arduino Lilypad, High Flex 3981 7×1 fach Kupfer blank conductive thread from Karl Grimm, Pure Copper Polyester Taffeta Fabric by Less EMF, white SMD LEDs, a coin cell vibration motor, and an IRL3103 MOSFET with a 100 Ohm resistor to drive the motor.
