RadarCat sensor

The next generation of smart sensors is coming... RadarCat (Radar Categorization for Input & Interaction) is a small, versatile radar-based system for material and object classification which enables new forms of everyday proximate interaction with digital devices. In this work we demonstrate that we can train and classify different types of objects which we can... Continue Reading →

Tiny Arduino clones

The Arduino Mini and Nano used to be the only options for small Arduinos. Now there are a number of independent Arduino clones, some funded on Kickstarter, that are tiny and cheap. I will post a spec and price comparison soon. Bareduino Nano Femtoduino TinyDuino Microduino

Small transistors

Some common NPN transistors are the 2N2222 and 2N3904. Look at the part numbers carefully as PNP transistors look the same! Most of the time, an NPN transistor will work for you. Here is a comparison of NPN vs PNP: These little guys can switch incredibly fast but have lower maximum ratings than TIP120's -... Continue Reading →
