In the Maker Shed: Real Time Clock Parts Kit

Real time parts clock kit
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!

  2. nootropic design says:

    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).

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 .
