It’s winter. It’s probably cold where you live. Running outside to start your car is probably one of the most dreadful experiences you have every morning, and then you gotta sit in your cold car for a few minutes before the heat really kicks in. You’re shivering. Trying to drive faster. And it all just sucks.
You could buy one of those remote ignitions, but then you gotta carry around an extra block on your keychain, and its range isn’t so great. Will O’Brien came up with a better idea – starting your car with your iPhone by sending it an SMS. It’s brilliant, and anyone can replicate his hack.
All you need to make the hack work is a jailbroken iPhone, an Arduino, an iPhone breakout board, and some random components.
“I send a text message from my phone with the phrase: “Start 1234? (1234 would be the password in the phone script). The phone gets the text then tells the arduino via serial interface to start. The arduino grounds the wire to the remote start that activates it. Meanwhile, the phone sends back a SMS saying ‘Executed’ to let me know that it got the message and is acting on it. In the future it’ll send back a message confirming that the start was executed as opposed to the I told him to do it method.”
