UsbSafe² – Programmable dongle for protecting USB devices from USB hosts and chargers
USB connections can transfer both information and power. UsbSafe² is a device for protecting USB-connected hardware from both excessive voltage, current and unauthorized data access. Unfortunately, the practice of “juice jacking” (accessing data from a device connected to a...

iBreathe, A Breathalyzer Based on Hexiwear
Knowing the amount of alcohol you drunk is becoming easier using the iBreathe Breathalyzer project by Dave Clarke. You just have to blow in the alcohol sensor, then it pings the result to a smartphone app and to the cloud to document it as a table so you can see alcohol intake through...
