This week on News 1130 radio in Vancouver, I spoke about these tech topics for Wired Wednesday with Ben Wilson:
- SprayPrinter: use your smartphone to paint a mural on a wall (source)
A new product called the SprayPrinter will be available this summer ($149US) that allows you to take any photo on your smartphone and using a special position tracking device attached to a can of spray paint and a companion smartphone app, allow you to point the paint can at a wall and it will activate the paint spray as you move along the wall. It can take just minutes to cover an entire wall with an image and multiple colours can also be used by switching paint cans for each colour ‘layer’
- Light-activated nanoparticles kill over 90% of antibiotic-resistant bacteria (source)
A new nanoparticle treatment developed by researchers at the University of Colorado Boulder could provide an effective means of fighting antibiotic-resistant bacteria including Salmonella, E. Coli, and Staphylococcus, based on results in a laboratory environment. In testing with a lab-grown culture, the nanoparticles killed 92 percent of drug-resistant bacterial cells while leaving the other cells intact.
- DietSensor Scans Your Food For Calories (source)
A device recently unveiled at CES allows you to ‘scan’ your food to quickly count the calories of the meal in front of you. The DietSensor works with your smartphone via Bluetooth and connecting it with a molecular sensor developed by SCiO. The molecules vibrate and interact with light in different ways, helping to determine what’s inside of the food. It’s expected to cost $250US and will be released this summer.
