You can Draw in the Air or anywhere with "3Doodler"

A 3Doodler allow anybody to write directly into the air by heating some plastic materials like PLA and ABS

The world’s first 3D-printing pen
– WobbleWorks’s 3Doodler – was launched in 2013,
This enables you to turn drawings into full-3D models on
any surface, without the need of any other software or computer. Unlike a normal pen, however,the 3Doodler doesn’t use ink, instead relying
on filaments of ABS(Acrylonitrile Butadiene Styrene) or PLA(polylactic acid) plastic, materials also used by most desktop 3D printers.

How it works

The 3Doodler prints by heating
three-millimetre (0.1-inch)-thin strands of

plastic, which need to be loaded into its back.
After turning the 3Doodler on and waiting a
few minutes for it to warm up, the LED
indicator light will then turn blue, which
means that the heated plastic can then
extrude from the 3Doodler nozzle’s metal tip –
the only potentially dangerous part, which
can get as hot as 270 degrees Celsius (518
degrees Fahrenheit).
Once the heated plastic leaves the nozzle, it
quickly solidifies into a strong, stable
structure, allowing you to build shapes with
ease. Because the heated plastic can be drawn
over almost any surface, including other plastic
There are two temperature settings so users
can switch between the different melting
points of ABS and PLA, and two main speed
control buttons allow for the heated plastic to
flow quicker or slower. This makes it possible
to create large items with a size able area to fill.

ABS(Acrylonitrile Butadiene Styrene)

One of the most common plastics around today is ABS,
or Acrylonitrile Butadiene Styrene. Made of oil-based
resources, it’s much stronger and less likely to snap

when bent compared to PLA, and has a higher melting point at 225 to 250 degrees Celsius (437 to 482 degrees Fahrenheit) for the 3Doodler.

PLA(polylactic acid)

PLA, or polylactic acid, is a biodegradable polymer, so it is considered better for the environment when properly recycled compared to ABS. It also comes in a huge variety of colors and can even be translucent. However, due to the lower melting point of 190 to 240 degrees Celsius (374 to 464 degrees Fahrenheit) for the
3Doodler, PLA is more prone to overheating and can droop if it gets too hot.

Vehicle Parking Management System in C++

this project is developed by Awais Azam Features Graphically display the parking locations(symbolically) Keep record of the arrival and departure of the vehicles with date-time specified Resume the data from the storage Can check history (arrival + departure) Automatically choose the parking location Alarm if any vehicle violate the parking order Description This project is coded in C++ using codeblocks compiler, it has almost 500 lines of code. easy for the beginners in the C++ language , almost each line is commented and explaining its purpose. As per the working of this app , for the first run it create some text files to keep the record of the vehicles , First screen show the menu from which user has to select an option as per his/her need As the screen shows , above is the screen shot of the application, it is not a small project as it looks like it almost cover all the major topics of C++ (not OOP) you can also check my other project which is also

Explaination Of Electron Gun

Thomson discovered the electron using this concept in 1897 after conducting experiments with cathode rays and studying their uses. Electron guns are a very versatile electrical component. They are essential to a number of devices, from 3D printers and welders to the large synchrotron at the Diamond Light Source in the UK and the electric systems of Kimball Physics in the US So how they work It’s all down to kinetic energy and electrical currents. When installed in an electrical device’s vacuum tube, the gun turns electrons and ions into usable beams of energy by releasing them from their metal source (cathode). This process is known as thermionic emission. Inside the gun there is a small filament that heats the cathode, which makes it release a stream of electrons. The electrons accelerate rapidly and the resulting beam is pulled toward the neighbouring anode, which is positively charged. There are small holes in the anode which allow some electrons to pass through, so a con

Sonic Weapons

To disperse crowds and prevent rioting, various forms of non-lethal weapons (NLW) are used. Among these, interestingly, is sound. Known as an acoustic or sonic weapon, infrasound (superlow frequency) and ultrasound (super-high frequency) greatly affect human ears. They can disorientate a target and have psychological effects as well as physical effects of nausea and damage to blood vessels. Explanation Ultrasound can be increased to 120 decibels (the same volume as a jumbo jet taking off), which is considered the human pain threshold. In contrast, infrasound feels like a damaging vibration or pressure wave, as it’s at a frequency too low for humans to hear. When exposed to high levels of sound, the influx of energy has a painful effect on the body. As well as huge decibels of volume, the variations in frequency can also cause damage. For instance, an infrasound of seven or eight Hertz can rupture blood vessels. Certain types of sound within the frequencies we are able to he
