Free Samples!

Wednesday, April 9th, 2008

I just ordered a whole bunch of MINITEC cases from www.okw.co.uk.  They’re these little project enclosures that you can strap to your wrist.  I think I might be able to think of a few project ideas for these.  I’ll probably have something new posted up in the ideas section sometime next week.  That is if I have time between my job interview and graduation.

Also I’ve been looking into how to go about making that VU meter tie.  I’m thinking that project might move to the works in progress section real soon.  As soon as I can pick myself up an LM3914N LED driver.  This thing should be perfect for what I need.

“Finished” Cantenna

Wednesday, April 9th, 2008

Well, I finished the cantenna today… sort of.  I say this because it appears to be working, but not very well.  At first it didn’t work at all.  It turns out I had made a fatal mistake when I mounted the “N” connector to the can.  The signal part of the antenna was touching the actual side of the can.  This caused a short.  The actual antenna signal was shorted directly to ground.  I had to take the mount off, wrap some tape around the antenna part, and then mount it back on.

The antenna seems to be working a little bit.  I can point it off into the distance and Kismet will show the signal strength increase or decrease for the surrounding networks depending on where I point it.  The signal change is usually only about 5-8db though.  I was really hoping for a better signal.  The trick here is that it’s difficult to tell where the problem is.  It could be the way I soldered the coat hanger piece to the connector.  It could be the way the connector is mounted to the can.  It could also be the way I soldered the small coax cable to the actual network card.  There are so many places this could be wrong.  Really the only way to figure this out would be for me to get a wireless card with an external connector and hook up the cantenna to it.  My guess is that I’m losing some signal in the solder connections I made on the wireless card itself.  For now, though, I’m done with this project.  I’ll fiddle with in on my wireless for some more testing but I don’t plan on trying to make it any better right now.  There are just too many variables.  Once I get some more money I’ll but a card with an external antenna connector and get back into this.

Another new idea and a cantenna update

Tuesday, April 8th, 2008

Today I only went to one class: Law370. Normally, I really hate the thought of going to the class, but it’s always a lot of fun. That professor really knows how to teach. I always learn something new from that class. Today, we were separated into groups and each group had to research a specific law regarding cyber-crime. This whole activity spawned a new project idea.

My group was assigned the CAN-SPAM act of 2003. This act basically has all these rules regulating how spam e-mail can be sent. I’m not going into that because it’s long, it’s complicated, and it really doesn’t matter for my project idea. My project basically will be a script that will crawl social networking sites like Facebook and MySpace to collect e-mail addresses. It gets more diabolical than that, though. The script will log onto someone’s MySpace account and get their e-mail. Then, the script will log onto each of that person’s “Top 8″ friends and get THEIR e-mail addresses. Now, the script can send a phishing e-mail to each of the friends on the “Top 8″ list and spoof the e-mail that it originates from to look like it is coming from the original person. I think this would be an awesome and fun proof of concept. I would never use actually use this for my own malicious purposes, although I would be interested to see how well it would actually work. I really just want to write this script just to do it. It would give me an excuse to brush up on my scripting and programming skills.

I think I’ll get started on this idea soon, seeing as it won’t cost me any money.

Another update here. I started working on the cantenna project some more. I bought the pigtail that I need, cut off one end and soldered it to the PCMCIA card. I’ve also soldered the piece of copper wire to the jack that attaches to the can. All I need now is a can to attach this thing too. The solder points on the PCB were so small, I’m not sure that the connections will be good enough. Hopefully I’ll find out tomorrow. I don’t have any class so I have the entire day off. I plan on getting a can either form the cafe at school or from the supermarket. I shall update the cantenna page as time permits.

New Idea

Monday, April 7th, 2008

Working for a company like CCBill gives me perspective on something that I hope to never have happen to me. Identity theft. I usually talk to at least a few people every day who are claiming that their credit card has been stolen. Some of these people don’t even realized it’s happened for over a year after it happens. Most of these unauthorized charges could have been prevented if the person had just checked their credit card statement more often. This makes me realize that I need to check my statement more often. Well, I’m lazy like everyone else and I often don’t think to check my statement. Hence, a new project idea was born.

Most banks or credit card companies have some feature where they will notify you if they see suspicious activity on your account. It’s obviously not always available and if it is, it’s not foolproof. I was thinking today that I should be able to write a script to check my bank account daily. This script would send me an e-mail alert or text message alert if it sees suspicious activity. I think to start out “suspicious” will equate to a sum of money over a certain amount. Eventually it could have complicated algorithms programmed in to determine if something is in my normal spending habits. Things like gas and food under certain amounts of money would be alright, whereas movies and internet subscriptions of any dollar amount would be flagged.

Also, on the topic of security I found a few websites that describe ways to secure Wordpress. I’ll have to go through these tonight to beef up my security. Here are the links:

More Updates

Sunday, April 6th, 2008

I added a few more pages. They all involve projects I want to work on, am working on, or have worked on. I also added some pictures to the cantenna page and the LED belt page.

Updates

Thursday, April 3rd, 2008

I just added two new sections under the “Pages” section. The first is Ideas and the second is Works in Progress. I also renamed the “projects” section to “completed projects”. I think this more effectively splits up the phases that my projects usually go through. Some never pass the Idea phase, while others get started and never get completed. This will help me to organize my projects and document how much I get completed and where I leave off.

I’ve also added some ideas I had for modding my graduation clothes. I still need some better ideas for that.

One other thing I added is the cantenna project. I’ve always wanted to build a cantenna and I finally started. I just need to buy some parts and get cracking.

Added: VU Meter tie to the “Ideas” section

LED Belt

Thursday, April 3rd, 2008

I started adding the LED Belt page last night. I need to get something up on here. It’s not completed yet. The first picture is terrible and the rest all are way too big in file size. I’m going to have to edit the photos in GIMP or something so that they can load faster. I also have yet to finish the description of the belt. I’ve been adding the description every time I add a new photo.

I also want to include the schematic for the belt’s circuit board. I believe I wrote one up in Eagle CAD a while back. I’ll have to see if I can locate that. Maybe I can also turn this into an instructable and post it up on their site as well.

Here’s another test post

Wednesday, April 2nd, 2008

Just testing out a few more things here.  Trying to figure out how all of this stuff works.

First Test!

This is my first test post on Wordpress.
