In the Maker Shed: Real Time Clock Parts Kit

Technology

Maker Shed

The Maker Shed is brought to you by Maker Media, the makers of MAKE Magazine, the Maker Faire, and much more.

Launched originally as a source for back issues of MAKE Magazine, the Maker Shed expanded rapidly to meet the demand for 'projects in a box,' otherwise known as kits. Now we have a little bit of everything for makers, crafters, and budding scientists, from Arduinos to sock monkeys to chemistry sets .

I don’t like alarm clocks. First off, they are always going off while I am trying to sleep. Secondly, they all look equally boring. Thankfully, the Maker Shed has a fix for the second problem. The Real Time Clock Parts Kit contains everything you need to make your own digital clock outlined in MAKE Volume 09. Just provide a unique enclosure and a buzzer, bell, or car horn. Wake up maker style!

What about source-code for the processor? we gotta modify it!

Why do clock kits always include a realtime clock chip when a microcontroller with a crystal is perfectly capable of keeping accurate time? I’ve built several clocks from microcontrollers alone, and they are very accurate (gain/lose a second every few days).
