A word clock – a clock that tells time with words, not dials or numbers – is one of those builds that’s on every Arduino neophyte’s ‘To Build’ list. It’s a bit more complex than blinking a LED, but an ...

We have seen quite a few different geeky clocks before on Geeky Gadgets, the latest one is this cool Arduino Weather Clock built by Sean Carney. Sean took an antique clock and removed the mechanism, ...

There are so many nice hacks in [Joekutz]’s retro LED display project that it’s hard to know where to start. There’s his DIY LED display controlled by an Arduino UNO. To have some text or picture for ...

I like this. Following on from the creative use of LEDs with the Periodic Table, check out this smart shelving system, similarly driven by an Arduino and using LEDs, that serves as a clock. Not a ...

Binary Clock is a clock that displays the current time in binary or decimal using a LED display. It really does not serve much of a practical purpose, unless your goal is to display the time in a ...

When is a clock not a clock? When it's a big fat, programmable, five-character, 18-segment display, a bit like the Alpha Clock Five from Evil Mad Science. Its 2.3 inch 18-segment alphanumeric ...

It’s amazing what you can make with a blonk of acoustic guitar wood, a string of LED lights, and some basic coding knowledge. Surely someone with a healthy imagination could figure out various ways to ...

Okay, I knew this would happen - one Arduino clock leads to another. Take a look at a clock that tells the time in terms of the first 192 digits of Pi, via a 32 x 8 LED matrix... Dubbed the Pi Day ...

Shadowplay strips the clock back to its basic elements, with an empty clock face bathed in light from the LEDs embedded in its plywood frame. There are no numbers, and no hands, at least until someone ...
