Wristwatch measures your perception of time; also tells time

This wristwatch is hiding a lot of features in its hardware and its software. It’s called the TicTocTrac and it’s a Senior project for a pair of students at Cornell University. Judging from the sheer volume and quality of the project documentation we wonder if someone has a science writing career ahead of them? Be we digress… It’s a clock and we love it!

First off, this does more than just tell the time. In fact, that’s almost an ancillary function in this case. The wristwatch is more of a metering device to record your own time-based behaviors. Find yourself checking your watch frequently as the lunch break approaches? This watch records that activity and you can later graph the data. This allows you to analyze how you percieve the passage of time. The more often you check the time, the slower you feel time progressing. The documentation does a much better job of describing this than we have time for, so check it out.

On the hardware side of things we’re quite impressed. The housing is 3D printed. It hides two half-circle PCBs below the full-circle PCB face plate. The half-boards leave space for a tiny rechargeable battery, and host a vibrating motor and RTC chip. Instead of using buttons, there’s a piezo sensor which detects when you tap on the top of the watch.

The Lunchtime clock gives you 12 extra minutes

The Lunchtime clock is a hacked clock that pulls a sneaky little trick to get you a longer lunch. In this instructible, [Randofo] shows us how he uses an Atmega168 and a realtime clock kit from Adafruit to slow the clock down 20% starting at 11:00 and then speed it back up at 11:45, gaining you an extra 12 minutes of sweet delicious lunch. Not really sure how noticeable this would be? Check out the video after the break. This is pretty hilarious and we can actually think of a few offices where this might work. However, many offices rely on their main network server for actual time keeping leaving this as just an amusing novelty. Still, those with luddite bosses can rejoice in your new-found extended lunch.

Time’s poll hacked


Though Time won’t admit it, their poll on the most influential person was hacked. Moot, the founder of 4chan is rated #1. Not only that, but if you read the first letters of the poll results, you get “Marblecake also the game”. This refers to the IRC Chanel where many 4channers congregate as well as “the game” an internet meme. This article is very interesting as it delves into the details of the attack. Focusing mainly on what happened when the autovoting software was shut down due to reCaptcha.  you’ve probably seen reCaptcha before. It presents you with two words, made difficult to read by strange kearning, warping, and squiggles. If you can read it, you’re most likely a human. Anon, a common name for 4channers, first tried to hack reCaptcha.

Their attempt at hacking reCaptcha relies on the process reCaptcha uses to identify words. It presents you with two words, one of which it already knows. The other is compared to a database of common responses to that word. Anon decided that if they entered “penis” enough times, they could flood the database allowing their autovoter to function again. This, though clever, was unsuccessful. They eventually settled on manual voting. This was taking too much time, they feared they would never reach their goals. To help with this, they built a simple interface that would preload several reCaptchas and cue up votes. This streamlining allowed them to squeak in the votes they needed to accomplish this.

It’s also worth noting that Time didn’t close the vote entries when the poll closed. They removed the poll from their site, but the streamlined vote software was still working. Anon is a powerful force of nature. If only we could harness it to cure cancer or HIV.

TIME’s Best Inventions of 2008


Attempting to put our past behind us as quickly as possible, TIME has released what they feel are the best inventions of 2008. While there’s some pretty wishy-washy lab-only stuff on the list, we’re glad to see a lot of cool hardware made the cut. Some of our favorites are: The Tesla roadster proving electric cars can be fun. IBM breaking the petaflop barrier with LANL’s Roadrunner. The Large Hadron Collider for getting everyone scared about physics all over again. Have a look at the list for many other tech highlights from this year.
