Quantum-logic clock is the new hotness in accuracy

The quantum-logic clock, which detects the energy state of a single aluminum ion, keeps time to within a second every 3.7 billion years. The new timekeeper could one day improve GPS or detect the slowing of time predicted by Einstein’s theory of general relativity. [via Wired Science]

BlokClok Project

Here’s a super-nerdy timepiece created using Arduino, a DS1307 real-time clock chip, four 74HC595 shift registers, and an 8×8 RGB dot matrix display. How does it tell time? The time is indicated using blocks of colour. The central 6×6 grid is split into 4 x (3×3) grids and each 3×3 block is a different colour. […]
