You need an audio wattmeter to measure the power output of your audio amplifier? You need one LM3915 IC and add a few passive components and you got a simple but effective audio wattmeter. This sound ...

The company was founded by electrical engineer Natasha Baker, who was constantly frustrated by the slow, inefficient processes to build even a simple circuit board.

Grinding out copper is one way to create a printed circuit board, and low-cost CNC milling machines have improved to the point where it’s possible for many.
