Rather than replace everything in the clock except the display, [zst123] is using the existing circuit board and adding an ESP8266 to grab the time from the Internet. A custom driver board reads ...

While we wouldn’t want to document a computer motherboard with ASCII schematics, it’s great for a quick-and-dirty circuit diagrams. Not exactly schematics, but [Duckman] has some Arduino ...

The Real Time Clock (RTC) SGC22300 uses the leading oscillator solution SGC21510. This specially designed RTC core uses advanced analog design techniques to guarantee ultra low power consumption ...

IC clocks are semiconductor integrated circuits (ICs) that are designed to keep time. IC clocks are important components in virtually all electronic components. They maintain synchronization and ...

As fast as required. A real-time system must respond to a signal, event or request fast enough to satisfy some requirement. For example, space flight computers must respond to changing conditions ...

We can see how circuits work, and represent them with some simple diagrams, using basic electrical components like these. You start with a cell, or combination of cells. These could be batteries ...

As convenient as it might be to use your phone as an alarm clock, standalone alarm clocks come with all kinds of features that can make waking up — or even going to sleep — a little less painful.

The shortening of days as the weather cools down means Daylight Saving Time (DST) is coming to an end, and it's almost time ...

The unofficial holiday is denoted by our cellphone clocks falling back an hour in the middle of the night, granting some of ...

The twice-annual changing of the clocks will happen on Sunday, Nov. 3 as the clocks "fall back" an hour, a tradition that is observed by most, but not all Americans. The opposite will happen in ...

Though fall arrived earlier this week, we’re still more than a month from the end of Daylight Saving Time and turning clocks back one hour. Daylight Saving Time ends at 2 a.m. on Sunday ...
