Fubarino Contest: NTP Clock

fubarino-ntp-clock

[Toni] has been playing around with NTP, the Network Time Protocol. This allows the alarm clock build to keep very accurate time by synchronizing with an NTP server on the Internet.

The project serves as a bedside alarm clock. When it comes time to wake in the morning an alarm sounds and the screen switches from using a blue backlight to using a red one. This is show in the video below, but you’ll want to turn down your speakers before watching it; the alarm sound will have no problem waking you up in the morning. After the unwelcomed jolt you’ll get a glimpse at the Easter Egg which reminds you to check for new posts on Hackaday.

Afraid of ending up with a steaming pile of slag instead of a server [Toni] asked us to host the project files. You can find the first-hand description of the project and a link to the code below.


This is an entry in the Fubarino Contest for a chance at one of the 20 Fubarino SD boards which Microchip has put up as prizes!

Router/Twitter/Arduino clock

ledclock

[Kyle] decided to build the above LED clock for his church. Though it may look impressive enough, it is also hiding loads of features. [Kyle] wanted to make the clock as easy to control as possible, so rather than use buttons or dials to control what is being displayed, he used Twitter. The clock is connected to the internet through a Linksys WRT54GL. The router was hacked so not only does it supply the connection to Twitter, it also parses all of the replies the clock’s feed gets. The clock responds to commands to turn it on or off, run a countdown before service, display the number of viewers on the church’s live stream, and display a sequence of numbers. The time never needs to be set, as it is synched from the internet. The circuit for actually driving the display is based off a PIC, but it was changed to run off an Arduino.
