On-dash g-meter project is another way to distract drivers

[PJ Allen] built a meter to display gravitation force in an easy to read way. Good thing it’s easy to read, because he’s added it to the dashboard of his car. That way he gets instant feedback when he puts the pedal to the metal. We’re hoping this encourages safe driving practices. But since it appears that not only is he watching the meter while he drives, he’s also holding a camera at the same time, we’d say this makes him a menace on the road.

But we do like the hardware concept. He used five Red/Green LEDs to show what the accelerometer is sensing. A green display reflects acceleration, while a red display shows deceleration. Inside the project box you’ll find a Parallax 2-axis accelerometer and an SX28 micrcontroller. This is an 8-bit Parallax chip family that was discontinued a few years back.
