Kostas made a pretty sweet mod to his motor bike. He’s come up with a cool way of sensing the spark via an inductive spark plug sensor. With that information fed into his Arduino, he can calculate the RPM of the motor and display it via 7 segment displays.
Some LEDs are used to indicate shift points just like a drag car. A Dip switch panel is used to set the shift points.
There’s a video after the break demonstrating it in action.

Isn’t it fun to take stuff apart and see how things are made ? Well Michael over at EDN likes to as well! He’s got one of those cheap-y eBay Bluetooth OBD-II adapters and while what’s inside isn’t much of a shocker, it’s still nice to look at how things are made.
Inside is a bunch of power regulation, a CAN bus transceiver, a Microchip PIC and a ready-made bluetooth module. Usually when you crack these cheap clones apart the soldering looks pretty shoddy, but this one looks pretty clean except for the Bluetooth module for some reason.
Check out the full teardown.
