Adding gearshift indicator to rally car

When race is on, the only thing that matters is concentration and thinking ahead. So you can’t keep track what gear is currently on. It is better to have this information in the field of view. Recursive Development Labs have built reliable gearshift indicator. They used AVR micro with Arduino bootloader. Most challenging part here is to read gear data from mechanical gearshift. The room was enough to place small potentiometer which is exposed to vibrations that lead to unreliable readings over time. So they came up with dedicated calibration routine that allows to fine-tune sensing by saving calibration data to EEPROM. The output of this device is a single seven segment LED indicator which displays current gear shifted. Continue reading

The Genuine Arduino Control Panel for Motorcycles

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
