Additional LED tachometer uses OpenXC

  By

Pete has bought new car and he wanted to build his own tachometer which would be more visible. So he built a LED ring based tachometer called Blueshift. The name already tells that data to tachometer is coming over bluetooth. Things become easy because new cars like Ford Fiesta is equipped with OpenXC API that is used by Android devices. It simply packs car diagnostic information in to JSON API which can be accessed via bluetooth. So Arduino with bluetooth module can capture this data and parse it to get tachometer data which then can be used to indicate on RGB LED ring. To make this indicator look great inside new car, he 3D printed nice enclosure which can be attached to front window. It obviously makes easier to see it with peripheral vision that looking at panel. And also it looks cool. Continue reading

The Genuine Arduino Control Panel for Motorcycles

  By

There are many electronic projects have been built based on the Arduino. You might have seen the Arduino Control Panel for Racecars or SUV, but have you ever heard about an Arduino Control Panel for Motorcycles? Yeah, it sounds like pretty amazing, isn’t it? Well, today’s your lucky day, where we’re going to build an Arduino Control Panel for motorcycles. Before that, you should know that the main purpose of developing this arduino control panel is to measure various locomotion parameters, such as the speedometer, tachometer and gear indicator. Although it’s still in the prototype stage, but it works perfectly without any hassle. For this project, you have to prepare these following components: A standard Arduino, A small LCD, and Bluetooth . Basically, the device is connected to the electrical system of the motorcycle to receive pulses from the tachometer and using a reed switch for wheel rotation. It starts to calculate the wheel speed in Revolutions per minute (RPM), divides it into most recent engine RPM and obtains a unique ratio for each gear! It’s very a fun and… Continue reading
