This Arduino Pro Mini powered clock syncs the current time via GPS, with a temperature compensated DS3231 RTC to keep it on the straight and narrow between satellite downlinks.

If you mention a clock that receives its time via radio, most people will think of one taking a long wave signal from a station such as WWVB, MSF, or DCF77. A more recent trend however has been for… ...

With the cheap GPS module that arrived from aliexpress.com, I leaped into action and on the couple of weekend afternoons I built upon this GPS clock. Parts required: 01. Ublox GPS Module with antenna ...

GRA & AFCH : IN-12 Arduino : Nixie clock kit with NTP V2 While the build in GPS works well, it can be an issue within well insulated home to receive GPS/ DCF signals from the outside. Hence the wish ...

The idea here is to use a cheap clock from IKEA, wire in a bunch of LEDs, connect and Arduino, and then use the 1Sheeld to trigger color changes depending on the traffic time between two points.

Sick of telling time the old way? Spice up your time-telling time with the open-source, hackable and Arduino -based DOTKLOK. Basically, you can get a bunch of different ways to tell time.

The NeoGeo watch is created using FLORA the Arduino wearable programmable board and its GPS module to tell the time using a ring of pixels and the skills required to create the watch are classed ...
