Read the time in glowing binary — like a geek would.
The Binary Clock displays the time the way a computer sees it: as columns of glowing LEDs, each lit dot representing a power of two. Add up the lit lights in each column and you have the hours, minutes and seconds in binary-coded decimal.
It is equal parts puzzle and conversation piece — a wonderfully nerdy desk clock that quietly teaches you to read binary the more you glance at it. For programmers, engineers, and anyone who loves a little daily brain teaser, nothing beats it.
Each column of lights is one digit of the time in binary. From the bottom, the rows are worth 1, 2, 4 and 8. Add up the lit lights in a column to get that digit — so lights on the 8 and 1 rows mean 9.
This clock uses binary-coded decimal: each decimal digit of the time gets its own column of binary lights, rather than encoding the whole number as one long binary value. It makes the display easier to read digit by digit.
It takes a few minutes. Because you glance at it all day, most people find they can read a binary clock fluently within a week — which is half the fun.
Programmers, engineers, students learning number systems, and anyone who wants a geeky, eye-catching desk clock that doubles as a party trick.
