Do a Jean Michel Jarre with your very own Laser Harp

Anyone remember Jean Michel Jarre’s laser performances, where he supposedly played synth leads by breaking laser beams? Some said it was fake, but nonetheless it is possible, as Stephen Hobley has proved with his Laser Harp.

To say it’s a custom build is an understatement. There are plenty of technical details on his web page, but if you just want to see it in action, take a look at the video below:

Sno-Baller: huge tongs for making perfectly spherical snowballs

Unless you’re in the highlands of Scotland, our British winters are rubbish enough that this low-tech gadget really won’t be much use. However, if you’re anywhere that enjoys deep, crisp, even snow, these Sno-Baller “tongs” could be just what you need.

It will produce perfectly spherical snowballs, great for lobbing at your mates, though it would be fantastic if you could also use them as a catapult.

Wake up at the perfect time with the Sleeptracker Pro watch

sleeptracker_pro_sleep_alarm_wristwatch.jpgThe Sleeptracker Pro is more than just a wristwatch. It’s a personal sleep monitor and an alarm which wakes you when your sleep pattern is closest to an “almost awake” moment. The desired result of this is that you wake up refreshed, rather than groggy. That’s the theory, anyway.

It’s supposed to be the first watch which can upload 12 hours of sleep data, via USB, to a PC, letting you take a look at your personal sleeping habits.

When coupled with the ability to manually add factors which may promote more restful, or cause more restless, sleep, it offers a useful sleep diary, alerting users to what may help them to get a better night’s sleep.
