Vehicles these days come with a lot of electronics but you can learn from our collection of car hacks to add your own custom features. For example, take the Jeep Wrangler and put in a couple of Arduinos, an LCD display, shift registers, relays, and you get the ‘JEEPuter’:
The JEEPuter is a programmable push-button system for controlling things like ignition, GPS navigation system, CB radio, RF scanner, 110V inverter, external and internal lights, and garage lights too. The JEEPuter also has temperature and light sensors which can set the dash lights and internal lights on autopilot. As a final touch, the Jeep’s ignition starts when you type a passcode instead of turning a key. While the JEEPuter is specifically for the Jeep Wrangler, you can learn from the build and apply the techniques to your own car.
