Is there anything you can’t build with Lego? Apparently not. A Lego enthusiast has recently created a pendulum clock that’s made from Lego pieces. What makes this clock stand out from other DIY clocks is that the clock’s timing isn’t handled by electronics – it makes use of mechanical concepts instead. If there was ever a more useful way to make use of your Lego pieces lying around the house, I think this would be it. It doesn’t look easy to create though, but you can check out more in-depth pictures of the device here.
