How to use Nmap

at 12:07 pm. Filed under Computer Hacks

 

Darren from Hak5 goes over a cool tool called Nmap. If you want to do some snooping or just some exploration on your own network this is a good tool to learn. Video after the jump.

"Nmap ("Network Mapper") is a free and open source (license) utility for network exploration or security auditing. Many systems and network administrators also find it useful for tasks such as network inventory, managing service upgrade schedules, and monitoring host or service uptime. Nmap uses raw IP packets in novel ways to determine what hosts are available on the network, what services (application name and version) those hosts are offering, what operating systems (and OS versions) they are running, what type of packet filters/firewalls are in use, and dozens of other characteristics. It was designed to rapidly scan large networks, but works fine against single hosts. Nmap runs on all major computer operating systems, and both console and graphical versions are available. "

Video Peggy in action

at 5:18 am. Filed under Complex Hacks, DIY Hacks, Electronic Hacks

 

This is a very impressive hack. It uses the cool Peggy that is made by Evil Mad Scientist Laboratories. It was originally created by Jay from Planet Clegg, best of all full instructions are provided so that you can make your own.

"While that’s pretty impressive, it’s also a bit invasive, since it requires rewiring the Peggy board. The new version of the project streams data to the Peggy 2 microcontroller over its TWI (also known as I2C) interface– a separate serial interface that’s available. An external Arduino board (or equivalent) sits between the host computer and the Peggy as a serial-to-TWI (I2C) converter."

Audio Modulated Tesla Coils

at 7:11 am. Filed under Complex Hacks, Electronic Hacks

 

Here is another Audio Modulated Tesla Coil setup. Geeks are Sexy did an interview with the maker of the machine.

"In addition to the interview with one of the ArcAttack members, John DiPrima, that we’ve conducted for our series on crazy inventors and inventions, we’ve also made sure that you’ll be able to enjoy renditions of “Popcorn” and the “Doctor Who” theme via audio-modulated freakin’ thunder."

Robotic Hand allows Amputee to feel

at 5:48 am. Filed under Complex Hacks, What Were They Thinking

 

There are many times our brains play tricks on us but this Robotic Hand technology takes full advantage of it by making amputees feel again.

"One potential solution is to wire sensors in robotic fingers directly into nerves in the stump, but this poses some technical challenges. So instead Henrik Ehrsson, a cognitive neuroscientist at the Karolinska Institute in Stockholm, Sweden, decided to see if a trick known as the "rubber hand illusion" could provide a simpler alternative."

Antitheft Suitcase using Motorola E-Field Sensor

at 5:18 am. Filed under Complex Hacks, DIY Hacks, Electronic Hacks

 

Having something stolen is one of the worst feelings, this Antitheft Suitcase design uses Motorola E-Field Sensor to combat theft by allowing you to enter in a code to disarm your bag.

"Loss or theft of suitcase during travel is a common occurance. It has recently happened to my dad also. This got me thinking. Also I have heard of jeweller suitcases that have alarms and also shocks a potential thief. A similar device can be implemented using an e-field sensor. This is much simpler than wiring the suitcase in any other way. There are 4 metal foil tabs, 2 on the left and 2 on the right. These are used as key pads to enter the arm/disarm codes. They are also wired to three e-field electrodes which is used instead of mechanical keys."
