This scooter starts right up with a shake of your Android device. This shake must be done from front-to-back, because a side-to-side shake is reserved for unlocking the saddle ([Brad] stores his helmet within).
Connectivity is facilitated over Bluetooth, with a rocker switch near the left handle bar to disable the receiver so that you don’t run down the battery. You can see the locking panel hanging open on the front portion of the scooter. Inside he installed the driver board which patches into the ignition system and drives a solenoid for the seat latch. It sounds like the latching mechanism used a bowden cable whose handle was inside that locking panel. By adding a solenoid and generously lubricating the cable he managed to get it functioning from the driver board.
Check out the video after the break for a proper demonstration. The phone is running a Python script via SL4A, which takes care of the user interface.

It’s just starting to warm up around here but it was very cold for a long time. We’re not fond of going anywhere when it’s way below freezing but those professional hermit opportunities never panned out so we’re stuck freezing our butts off. Fed up with his frigid auto, [Aaron] installed a remote starter to warm the car up before he got to it. This didn’t help at work because of the distance from his office to the sizable parking lot is too far for the key fob’s signal to carry. He decided to make his starter work with GSM so he could start the car with a phone call.
The first attempt involved a pre-paid cell phone for $30. The problem is that anyone who called the phone would end up starting the car. After a bit of looking he found a GSM switch that just needs an activated SIM to work. When called, it reads the incoming phone number for authentication but never picks up the phone so there’s no minutes used. He cracked open an extra key-fob and wired up the lock and start buttons to the relays in the GSM switch. Bam! A phone call starts (and locks) his car.
Maybe this isn’t as hardcore as body implants but it’s a fairly clean solution. He uses the car’s 12v system to power the switch and pays $10 every three months to keep the SIM card active. There’s an underwhelming demonstration video after the break showing a cellphone call and a car starting. Continue reading “GSM car starter”
