Do you like to feel acceleration while driving a car? There is a way to see that force in numbers.
Great thing is that accelerometers are really cheap and small today. They come in small IC packages that can be easily integrated in to embedded devices. In order to interface ADXL320 accelerometer you need a microcontroller with analog input. This circuit uses a PIC18F452 which reads an accelerometer data and displays F-force on three 7 segment LED displays. G-Force meter is a real straight forward sensor which read and outputs data directly to display. Program is written in C language for C18 compiler. It can be great addition to you car or anywhere where you feel acceleration.
