Lock and unlock Windows 7 or 8 with a physical key

For those Windows PC users who don't like remembering passwords but require a level of access control to their machine, the following project by Thomas Kirkup offers a neat solution to the problem. It allows the use of a two-position key barrel switch as a device to lock or unlock the Windows workspace - so the simple turn of a key can replace the keypresses and password entry required. It's simple, works and is demonstrated in the following video:

Kudos to Thomas for such a useful idea, which can easily be modified to emulate any manner of USB HID entry sequences. Visit his Instructable page to learn more. And for more, we're on facebookGoogle+, and twitter - so follow us for news and product updates as well.  

Need an Arduino Leonardo-compatible for projects like the lock above? Check out out LeoStick board - It's the Arduino Leonardo-compatible board that's cheaper and smaller than the original:

 Apart from being one of the smallest Arduino-compatibles on the market with USB, it also has an onboard RGB LED and piezo which can be used a knock sensor and various tune and sound effects. Plus you can add extra circuitry with the matching protostick! For more information and to order, click here.
