We’ve seen a fair share of carputer builds involving a Raspberry Pi in the last few months, but even the power of a Raspi can’t compete with the awesomeness of this Arduino-powered scooterputer.
Like all awesome projects, this build is the product of a massive case of feature creep. Initially, [Kurt] only wanted a voltage monitor for his battery. With an Arduino Duemilanove, a voltage divider, and an evening of coding, [Kurt] whipped up a simple device with three LEDs to indicate the status of the batter: either low, good, or charging.
The project was complete until he ran across an awesome OLED screen. Using a touch screen display for just battery monitoring is a bit overkill, so [Kurt] made a trip over to Sparkfun and got his hands on a temperature sensor, real-time clock, accelerometer, GPS sensor, and even a cellular shield.
The resulting scooterputer is a masterpiece of in-vehicle displays: there’s a digital speedometer and GPS unit, and the cellular shield works as a tracking device and a way to download real-time maps of the scooter’s current location with itouchmap.
While the majority of the electronics are hidden under the hood of the scooter, the display of course needed to be out in the weather. To do this, [Kurt] found a nice enclosure with a rubber boot that perfectly fit the OLED display. The display is connected to the Arduino with a cat5 cable, and everything should hold up pretty well as long as [Kurt] doesn’t drive through a hurricane.
