Argos takes on Amazon with UK-wide same-day deliveries

In the past couple of years, Argos has unveiled a number of new initiatives aimed at differentiating itself from its retail rivals. We've seen it open click-and-collect stores on the Tube, partner with eBay to let online users pick up their deliver...

Google Translate works within apps for Android Marshmallow users

When Android Marshmallow arrives on your device, you can also get a really handy update for Google Translate. Instead of having to switch between apps to translate text, you'll be able to do some language switching right within the app you're using...

Jumping robot uses safety tethers to control its fall

Spiders don't typically jump off ledges without some sort of plan. Many species of jumping spider (family Salticidae) will affix themselves to their perch with a silken thread that acts as a safety tether. Researchers at the University of Cape Town...

VW’s Giant Diesel Recall of Shame Begins in January

VW is still in full damage-control mode over its cheating diesel cars , and slowly but surely, the pieces are falling into place: if everything goes to plan, the first cars in Europe will be recalled in January 2016, to be finished by the end of 2016. That’s a long time to use a rental.


Robot Clock Writes Time Over and Over and Over

We’ve seen quite a few clocks that write the time out with a pen or marker. If you think about it, this really isn’t a great solution; every whiteboard marker will dry out in a day or two, and even if you’re using a pen, that’s still eventually going to run out of ink.

[ekaggrat] wanted a drawing clock that didn’t have these problems, and after taking a look at a magnetic drawing board, was struck with inspiration. The result is a clock that will perpetually write the time. It’s a revision of one of his earlier builds and looks to be much more reliable and mechanically precise.

A clock that writes time needs some sort of surface that won’t degrade, but can be written to over and over again. Whiteboards and glass won’t work, and neither will anything with ink. The solution to this problem was found in a ‘magnetic writing board’ or a Magna Doodle. These magnetic writing boards have a series of cells encapsulating iron filings. Pass a magnet over one side of the board, and a dot of filings appear. Pass a magnet over the opposite side of the board, and the filings disappear.

[ekaggrat]’s time-writing robot consists of a small Magna Doodle display, a robotic arm controlled by two stepper motors, and two solenoids on the end of the arm. The kinematics come from a helpful chap on the RepRap forums, and with the ATmega644 and two stepper drivers, this clock can write the time by altering the current flowing through two solenoids.

A video is the best way to experience this project, and you can check that out below.

For $40,000, This Bang & Olufsen Speaker Should Play Sound in 11 Dimensions

Bang & Olufsen will freely admit that its new BeoLab 90 speaker is ‘not for everyone’. Given that most people can’t blow $40,000 on a car, let alone speaker-systems-as-modern-art, that’s not surprising. But at least for the money, you should get a nice hi-fi.
