IoT or the Internet Of Things is gaining popularity rapidly and at the same time their security is also becoming a matter of concern. Recently there has been reports about various IoTs being vulnerable to hacking,like hacking baby monitors,Hacking Smart Cars,Hacking Gas Stations & Blowing them up and even Smart Fridges which can lead to compromising Gmail accounts. So far there is no comprehensive tool dedicated specially for auditing the security of Internet Of things.
What is HardSploit?
HardSploit is an all-in-one hacking tool for hardware security audits,especially for the IoT devices. It is a complete tool box (Hardware + Software),a Framework which aims to:
- Facilitate the audit of electronic systems for industry ‘security’ workers (Consultant, Auditor, Pentesters, product designer etc.)
- Increase the level of security (and trust!) of new communicating products designed by industry
According to the creators HardSploit is a tool with software and electronic aspects. They called it a framework because that is a technical and modular platform (using FPGA) to perform security tests on electronic communications interfaces of embedded devices.

Many companies want to sell you “memory optimizers,” often as part of “PC optimization” programs. These programs are worse than useless — not only will they not speed up your computer, they’ll slow it down.
Such programs take advantage of inexperienced users, making false promises about boosting performance. In reality, your computer knows how to manage RAM on its own. It will use RAM to increase your computer’s performance — there’s no point in having RAM sit empty.
Memory optimizers are based on a misunderstanding. You may look at your computer’s RAM and see it filling up — for example, you may have 4 GB of RAM and see that 3 GB is full with only 1 GB to spare. That can be surprising to some people — look how bloated modern versions of Windows are! How are you ever going to run additional programs with so little memory available?
In reality, modern operating systems are pretty good at managing memory on their own. That 3 GB of used RAM doesn’t necessarily indicate waste. Instead, your computer uses your RAM to cache data for faster access. Whether it’s copies of web pages you had open in your browser, applications you previously opened, or any other type of data you might need again soon, your computer hangs onto it in its RAM. When you need the data again, your computer doesn’t have to hit your hard drive — it can just load the files from RAM.

The main function of a Preamplifier is to amplify small and weak signals for further amplification. Generally, weak signals from microphones, audio sources and other sound detectors must be extracted with compromising the intrinsic signal to noise ratio (SNR).
Hence, the best position of a preamplifier is close to the sensor or detector. The output of the preamplifier is further amplified by Power Amplifiers.
Preamplifier amplifies the signal with very high gain but doesn’t have the drive current or current gain to drive the output. Hence, the boosted signal from preamplifier is given to a power amplifier where the current is amplified.
We are thrilled to announce; we have teamed up with Cytron Technologies to bring the Cutting-edge Robotic Technology to Malaysian Academic Community. Little Botz™ Academy and Cytron Tech. launched collaboration to advance student learning using RERO robotics with our Jr. Facilitator program this March 2016. This program will provide special training to our community (public/students/teachers/professors) who is interested in using RERO robot within their daily curriculum that will meet Science and Technology Standards.
NEWS UPDATE: Little Botz™ Academy is pleased to announce its new strategic partnership with FLLCast, a leading community portal for First Lego League, which aims to assist students to develop further, so that we could have a better competition while introducing our students to robotics.
Tomorrow’s innovators practice imaginative thinking and teamwork. Guided by adult Coaches, FIRST LEGO League teams research a real-world problem such as food safety, recycling, energy, etc., and are challenged to develop a solution. They also must design, build, program a robot using LEGO MINDSTORMS® technology, then compete on a table-top playing field.
It all adds up to tons of fun while they learn to apply science, technology, engineering, and math concepts (STEM), plus a big dose of imagination, to solve a problem. Along their discovery journey, they develop critical thinking and team-building skills, basic STEM applications, and even presentation skills, as they must present their solutions with a dash of creativity to judges. They also practice the Program’s signature Core Values.

Robotics is the study of robots. Robots are machines that can be used to do jobs. Some robots can do work by themselves. Other robots must always have a person telling them what to do.
How Does NASA Use Robots?
NASA uses robots in many different ways. Robotic arms on spacecraft can move large objects in space. Robotic spacecraft can visit other worlds. Robotic airplanes can fly without a pilot aboard. NASA is studying new types of robots. These will work with people and help them.
What Are Robotic Arms?
NASA uses robotic arms to move large objects in space. The “Canadarm” robotic arm is on the space shuttle. The International Space Station has the larger Canadarm2. The space shuttle uses its arm for many jobs. The Canadarm can release or recover satellites. Astronauts have used it to grab the Hubble Space Telescope. This let them fix the Hubble. The shuttle and space station arms work together to help build the station. The robotic arms have added new parts to the space station. The arms also can move astronauts around on spacewalks. The space station’s arm can move to different parts of the station. It moves along the outside of the station like an inchworm, attached at one end at a time. It has a robotic “hand” named Dextre that can do smaller jobs. An astronaut or someone in Mission Control must control these robotic arms. The astronaut uses controllers like joysticks used to play video games.
How Do Robots Explore Other Worlds?
Robots help explore space. Spacecraft that explore other worlds, like the moon or Mars, are robots. These include orbiters, landers and rovers on other planets. The Mars rovers Spirit and Opportunity are robots. Other robotic spacecraft fly by or orbit other worlds. These robots study planets from space. The Cassini spacecraft is this type of robot. Cassini studies Saturn and its moons and rings. The Voyager and Pioneer spacecraft are now traveling beyond our solar system. They are also robots. People use computers to send messages to the spacecraft. The robots have antennas that pick up the message commands. Then the robot does what the person has told it to do.
How Does NASA Use Robotic Airplanes?
NASA uses many airplanes that do not carry pilots aboard. Some of these airplanes are flown by remote control. Others can fly themselves, with only simple directions. Robotic planes help in many ways. They can study dangerous places. For example, they might be used to take pictures of a volcano. They let NASA try new ideas for aircraft. These planes can fly for a long time without the need to land. They also can be smaller than a plane flown by a pilot. They may not have room for a person to be on board.
How Can Robots Help Astronauts?
NASA is developing new robots to help people in space. One of these ideas is called Robonaut. Robonaut looks like the upper body of a person. It has a chest, head and arms. Robonaut could work outside a spacecraft. It could do work like an astronaut on a spacewalk. With wheels or another way of moving, Robonaut could work on another world. Robonaut could help astronauts on the moon or Mars.
Another robot idea is called SPHERES. These small robots look a little like soccer balls. SPHERES are being used on the space station to test how well they can move there. Someday, robots could fly around the station helping astronauts.
NASA is studying other ideas for robots. A small robotic arm could be used inside the station. A robot like that might help in an emergency. If an astronaut were seriously hurt, a doctor on Earth could use the arm to perform surgery. This technology could help on Earth, as well. Doctors could help people in faraway places where there are no doctors.
Robots also can be used as scouts to check out new areas to be explored. Scout robots can take photographs and measure the terrain. This helps scientists and engineers make better plans for exploring. Scout robots can be used to look for dangers and to find the best places to walk, drive or stop. This helps astronauts work more safely and quickly. Having humans and robots work together makes it easier to study other worlds.
