1. How long is five minutes?

The Durr unisex bracelet vibrates every five minutes to help you align your own time perception. Apparently it's a common need, since the small alpha batch are already sold out.

You can sign up to be notified of the next batch or keep an eye on the blog which details the process of building and shipping the Durr units.

2. America Tonight on the Quantified Self movement

Gary Wolf, who co-founded the Quantified Self movement with a fellow Wired magazine editor in 2007, estimates that there are tens of millions of people around the world using computers to track themselves. That number, Wolf said, is likely to balloon to the hundreds of millions “in a blink of the eye.”

I really liked this comment from Gary Wolf, as well:

“I do think that what’s going on in the world of the Quantified Self is based on some fundamental human practices and desires and needs to take stock of one’s self.”

3. NeuroOn: the world's first polyphasic sleep mask

This Kickstarter campaign has raised almost four times as much as their initial goal, but there's still a week left to get your order in for a NeuroOn sleep mask.

According to the Kickstarter page, the NeuroOn will track your brainwaves and wake you up after REM sleep cycles to ensure you wake up rested and energised:

NeuroOn is the world’s first brainwave - monitoring SLEEP MASK that allows you to switch from monophasic to polyphasic sleep. That means you can sleep less and more efficiently.

4. Track your habits with Habit List (and more)

• Lift
• Way of Life
• The Habit Factor
• Clever Routines
• Habit Streak
• Everest

5. A typical 2013 weekday

Jamie Todd Rubin used his self-tracked data from 2013 to explore what his typical weekday looked like. He included data about his time spent sleeping, reading, writing, working and walking.

It's only a short blog post, but it's interesting to see what Jamie did with his data after a year of tracking.

6. You can now use Fitbit without buying a device
