If you’ve done the whole tweeting every time your unborn child kicks, perhaps it’s time for something a bit creepier. This device will give your Twitter followers a live feed of your heartbeat, including “pre-recorded” messages to announce your death should you shuffle off this mortal coil.

This DIY project is open source and will send the news of your heart directly to the internet. That way should you stop supporting the Iranian revolution, we will all know why. It was probably one too many cheetos and the terrible let-down of a Transformers movie that was too much for your soul to take.

Do your fingers get tired from excessive tweets? Well, there’s help on the way. Just use brain power to send messages via Twitter without lifting a finger. You can thank Adam Wilson, who has come up with a brain interface that allows you to post Twitter messages with no hands. Though you will have to wear the dorky electrode cap.

The display shows individual letters and when the user focuses on a letter, it will type it. It’s slower than using a keyboard, but soon it should get faster. Who wants to use their fingers anyway? That’s so last century.

This latest Arduino project turns it into a twitter home security system of sorts. The Arduino is used to monitor a home burglar alarm and send out status messages should the status change: Like when the alarm was activated or shut off, error messages, or just when the alarm actually sounds because you are being robbed.

The Arduino’s digital IO pins are wired up to the alarm’s output signals. An XBee wireless module was added, because the alarm control panel is some distance away from the ethernet hook-up, and a simple Linux server (with the USB XBee receiver) monitors any changes and sends the Twitter messages. @alarmdude By the time help gets here I’m gone. Left the zune on your desk.
