Make your own laser "sleep remaining" clock

 When you wake up in the early hours of the morning and wan to know how much more sleep you can get in - however have trouble focusing on the clock, this may be the project for you. Niravel Patel has created an interesting method of display how many hours are left in a user-set period by shining a laser pointer between vertical and horizontal. The device has a potentiometer which is set to a certain number of hours, and during that period of time the laser is rotated by a servo at a constant rate until the beam is horizontal - at which time your sleep is (theoretically) over. For example:

What a great idea. To get started, visit the project pageAnd for more, we're on twitter and Google+, so follow us for news and product updates as well.

If projects like this interest you, however you're not sure about using servos or Arduino in general - don't panic! Check out our new Experimenter's Kit for Arduino:

The package includes a wide variety of parts, sensors and modules including: a servo motor, lights, buttons, switches, sound, sensors, breadboard, wires and more. Furthermore a Freetronics Eleven Arduino-compatible board is included to make this an extensive hobby experimenter, inventor and starter kit. However we don't leave you alone to figure it all out, included is a great project and instruction booklet, plus access to a supporting web page and software examples. In other words - this is everything you need to get started for a fun range of electronics and Arduino related projects! 

So to get started or for more information and to order, check out the product page.
