Quin Etnyre has been into all things Arduino since he was a kid. He already has 28 Instructables published, founded his own company called Qtechknow in 2012 which sells ArduSensors and a line of fun and educational kits and oh, he is still just 14 years old.
His latest Arduino-based design is the Qduino Mini which is the first tiny Arduino compatible board to incorporate a battery charger and fuel gauge to let you know when the battery needs recharging.
The Qduino Mini is 1 inch by 1.5 inches and weighs just 5 grams which makes it ideal for use on airborne projects such as quadcopters, drones or high altitude balloons.
