This project needs properly documenting, but in short it’s a Diecimila with a network module a 6V buzzer and tri-colour LED connected to PWM which provides an audible and visible alert upon the receipt of specific new emails.
I run Ubuntu and Evolution mail on a wireless laptop which has a filter configured to pipe all incoming mail to a bash script. The bash script then passes the email content over to PHP (where I’m most familiar) and parses it for support@ and other references. The PHP script upon triggering a ruleset visits the network connected Arduino using curl, sounds the buzzer for one second and phases the PWM LED through Red and Purple to provide a visual alert before reverting back to buzzer off and blue state. It’s pretty basic but it means I don’t need to be anywhere near the laptop to be able to jump on a support ticket.
Install the latest smokeping (without distributed polling) on a virgin Centos 5.3 minimal box… It’s probably the best (free) tool for monitoring network latency at a glance.
Examples: Pipe Ten Derby and Pipe Ten Sheffield.
A quick reference for a from-scratch Zabbix install on CentOS 5.3. We’ve used Zabbix for the past 3 or 4 years and just implementing 1.6.5 across multiple Xen nodes for funky distributed monitoring.
I’ve faffed with this one and poorly hacked some jquery and facebook connect examples along with trusty ol’ PHP on the front-end, on the back-end is a nice c scheduler engine which seems to be …
JFGIT.com was just a quick domain registration, modification of the google home page and a bit of mod_rewrite. It’s intended for the ‘education’ of people too lazy to use the wonderful search tool called Google.

After an IRC conversation about GPS, we randomly got onto a discussion about finding the cheapest petrol prices and where those services get the data.
There were a few ideas:
/*
This code receives input from the SRF02 ultrasonic and maps the values to RGB outputs to a tri-colour LED.
*/
An electric arc is an electrical breakdown of a gas which produces an ongoing plasma discharge, resulting from a current flowing through normally non-conductive media such as air.
As far as I can tell there’s an …

If you’re feeling sorry for yourself, then see how you feel after watching what happened a few generations ago in ww1 (not forgetting the other wars, invasions and defenses and ages)…
I’ve just been playing with a new HD44780 4×20 LCD from ebay on the Arduino. As I’m still ‘playing’ I’ve tried to document a kind of breadboard interface for the Arduino to LCD. It should …
