Build an Arduino-powered liquid Tidal Clock

We never get tired of seeing different types of clocks, and this next example by Instructables user make77 certainly fits the bill. It's a tidal clock, used to display the progress of the tide at the shore. However instead of just using a digital display or an LCD - the clock "displays" the tide level with an actual, variable level of blue liquid. At at glance you can then see the tide level by looking at a miniature replica of it, for example:

The enclosure consists of two chambers, both holding a quantity of the blue liquid. As the tide data changes, the liquid is displaced by a device inside the rear chamber and can then control the level of liquid in the visible front chamber. It really is quite genius, and the creator has published all the design files required to make your own. And for more, we're on twitter and Google+, so follow us for news and product updates as well.

 If you're looking into controlling a stepper motor (or DC motors) from your Arduino or compatible, check out our new HBRIDGE: DC/stepper motor shield. Based around the powerful Allegro A4954 H-bridge driver IC you can control two DC motors with complete ease, or one bipolar stepper motor. With connections for external power management, a complete beginners' guide and documentation - motor control couldn't be any easier. For more information and to order, visit the HBRIDGE: page
