MAKE presents: Ohm’s Law
Voltage, Current, and Resistance – three of the most important electrical properties, are elegantly intertwined by way of a simple equation; V = IR, better known as Ohm’s Law. Get to know this fundamental tool of electronics engineering – you’ll be glad you did! [via]
This is a really nice 3D animation made using Cinema 4D demostating the construction procedure of Drawdio. Drawdio is actually a pencil that lets you draw music. You can find more info on their website [via]
