I ran across this project a few years ago but never posted it or even saved the URL. It's a security system for a summer cottage that uses a PIC, IR Sensor and a GSM phone circa 2002 to send text message alerts if someone breaks into the place. Not a bad project for the day, and it has a cool case too.

A few months ago a co-worker was asking me how difficult it was to install Linux. Of course this is a very obscure question because it really depends on the distro. So I began with some of the easier Distributions to install (Ubuntu, OpenSUSE, Fedora Core) and explained to him that the only big difference between these distros is its package management system and that any of the three were a viable option. I then remembered my very pleasant experience with installing Ubuntu and gave him a Ubuntu 7.04 install cd.
I ended up completely forgetting that we even had that discussion and the other day he came back to me thanking me for giving him the Ubuntu cd. He was so impressed that he booted up the live cd, installed it in about 20 minutes and even his wireless card just came to life. As a matter of fact he is so impressed with the Ubuntu distribution that he installed it on his mothers PC and is trying to get his brother to convert from windows.
The ease of installing the standard Ubuntu 7.04 is allowing more and more people to switch over to Linux and give it a shot. I myself was pleased that they still offered a non-graphical installation alternative (what can I say, I like when the install is difficult; It makes me feel much more satisfied once I have finished.). But one thing that I must say is that the out of the box driver support is phenomenal! The lack of support on other distros and having to manually configure so many hardware devices is what makes running Linux a Geeky thing to do.

Found this plotter on Makezine today. The Plotter uses a pen to do graphical drawing on paper, glass or even PCBs. The mill looks like an upgraded version of the plotter. Not a whole lot of details on how it works other than a few screen shots of the software and board. Still, enough to stimulate the mind and get those thoughts of your own mill going.

I found a great tool for those of us that choose to (or are forced to) use ASP rather than PHP to build our web applications. The DynuEmail ASP Component boasts a large number of email creation functions making it very simple to send an email through a mail server without much difficulty. They have a free version the only downside is you cannot redistribute it and it does not come with the source. If your looking for a free email component and don't really care about the source here is your bread and butter.
The component is very easily setup to send emails. It covers all the basic email functionality without the need for all the complicated configurations and setups. All you need is an SMTP server. Once you have an SMTP server you can actually use this Component to direct emails from your domain but any address, even addresses that are not created on the server such as no-reply@test.com. That way you don't have to worry about incoming email responses, they will just be denied.
If your into ASP and building websites I would definately take a look at DynuEmail here.

Embedded.com and EETimes have an interesting story on an 8 year old kid who enjoys playing with FPGAs. Field Programmable Gate Arrays are chips who's internal hardware can be re-wired to produce complex logic solutions. Most modern FPGAs can even be programmed' to have one or many CPUs on them.
I think it's cool an 8 year old is playing with VHDL. Just getting a LED blinking on a dev board is a big step for most who are new to VHDL.
Hey Carson, drop us a line and we'll give you a GI blog!

Check out this AVR controlled power supply from from TuxGraphics.org. The supply has a voltage range of 0-22 volts with a max output of 2.5 amps, more than enough for almost all home projects. On their website is a writeup on how it works and includes the code written for an ATmega8 from Atmel. They even sell a kit with most of the components needed (minus the LCD and power source).
Good project for those who want an advanced PSU but don't want to spend the mega bucks.
