6th Rendition

This is the 6th rendition of the G-1. We are currently working on redesigning the tail and correcting the ratio to 3:1. The tail is way too short! :o




DKUMX, a training plane built like a tank for newbies to experiment with. It flies like a tank too. There was only one goal when designing this plane: for it to survive 100 crashes on pavement

These are photos that show the plane from pre-to-post production.

Alex: What’s not shown is the installation of the engine, that’s because the specific unit we are going to use to power it isn’t here yet, so I installed a temporary piece of junk motor that is underpowered, and can’t actually keep the plane in the air for long.

Minecraft Server on the Amazon EC2

Okay, here’s a simple tutorial (or not, since I’m in a rush) showing you how you can run a Minecraft server off of the Amazon EC2 web service. You don’t need to pay, as long as you don’t exceed the limits of the free tier usage plan. The server can support up to 3 – 4 players without any problems.

1. First, go to http://aws.amazon.com/ and sign up for an account. You will need your credit card information.

2. Once you have signed up, go to the EC2 Management Console and under ‘Network & Security’ select ‘Security Groups’. Create a new security group titled w/e Minecraft. (Doesn’t really matter what you name it). Add two new Inbound Rules. One Custom TCP Rule for port 25565, and one SSH rule.

3. Then under ‘Network & Security’ select ‘Key Pairs’. You need to create a new Key Pair. Once again, it can be titled as anything you like. Download the pem file.

4. Now, under ‘Instances’, create a new Instance. This will be your server. Create a Amazon Linux instance using the first plan (eligible for Free Tier). When prompted, use the Key Pair you created earlier. Once this is done and you have completed the setup wizard, the server should start running.

5. Congrats, you are halfway done! Now all you need to do is download the Minecraft_server.jar onto your server. For this part, I chose to use the browser SSH client.

6. Launch the SSH Client of your choice. Type

wget https://s3.amazonaws.com/MinecraftDownload/launcher/minecraft_server.jar

into the client. This will download the .jar file onto your server.
Then type:

java -Xmx1024M -Xms1024M -jar minecraft_server.jar nogui

This command will start your Minecraft server. You can now connect to your server via the  Elastic IP address found in Instances. :)

Spoof MAC Address

This is a simple way of gaining unrestricted access to the internet at hotels or coffee shops. You will need to download Cain & Abel and Etherchange. Both software are available freely online. This will not work if you are required to visit a login page before being granted access. You will need to use an injection technique or bruteforce the form for that. I have written a simple bruteforce application, but it’s success rate is very low. Anyway.

1. Install Cain & Abel and run it.
2. Turn on Sniffer and wait until Cain & Abel finds other users on the network. Most users will likely have paid for access and are not just idly sitting on the portal page.
3. Once Cain & Abel has found the MAC addresses for other users on the network, open Command Prompt. You will need to set the directory of where you downloaded Etherchange as the working directory (using ‘CD’).
4. Start Etherchange from the Command Prompt. It will prompt you with options; select option 1. Then enter the MAC address of the computer you want to spoof and press enter.
5. Next, you will need to disable and then re-enable your wireless adapter. This is fairly easy. Go into your network adapter settings, and right click on your adapter. You will find the option to disable there.
6. You should now have the MAC address of your target. Have fun!
7. When you are done, simply start Etherchange again and select option 2. This should re-establish your genuine MAC address.
