The OLabs is based on the idea that lab experiments can be taught using the Internet, more efficiently and less expensively. The labs can also be made available to students with no access to physical labs or where equipment is not available owing to being scarce or costly. This helps them compete with students in better equipped schools and bridges the digital divide and geographical distances.

The experiments can be accessed anytime and anywhere, overcoming the constraints on time felt when having access to the physical lab for only a short period of time.

Basics lab of Physics, Chemistry, Biology

Interactive simulations, animations and lab videos.

The concepts and understanding of the experiment.

The ability to perform, record and learn experiments - anywhere, anytime, and individualized practice in all areas of experimentation.

The REACH-DL is a home-based lab kit designed for distance learning and online students. The kit contains the sensors, recording software, and write-ups to perform over 10 core experiments introducing your students to the fundamentals of cardiovascular, neuromuscular and respiratory physiology.

Each exercise is laid out in a step-by-step, simple-to-use fashion, allowing your students to perform hands-on experiments at home, easily analyze their findings, and generate a report.

REACH-DL includes:

• REACH Physiological Recorder
• LabScribeDL Recording and Analysis Software
• Set of 5 snap leads for ECG/EMG and Respiration (C-ISO-SL5)
• 50 electrodes ECG/EMG/Respiration Electrodes (A-ELEC-50)
• Kit Box (A-KB-REACH)

• Its great online IDE powered with the code editor, compiler and debugger.
• It supports C, C++, PHP and Java Compilers.
• The unique feature of OnlineGDB is, you can debug your code step by step.
• Once the code is written, it can easily be formatted to make it look nice.
• This is a very handy web app for coders who love coding in online IDE but faces unexpected crashes and tricky bugs in their code.

• Ideone is an online compiler and debugging tool which allows you to compile the source code and execute it online in more than 60 programming languages.
• Ideone is a standard online IDE that allows to edit, compile, execute and share single C++ files.
• Ideone is easy to use an online compiler.

• Test your JavaScript, CSS, HTML or CoffeeScript online with JSFiddle code editor. (JavaScript, MooTools, jQuery, Prototype, YUI, Glow, and Dojo)
• Lots of people and companies use JSFiddle for online examples of their JavaScript libraries/products.
• JSFiddle has the notion of panels there are 4 panels, 3 where you can enter a code(HTML, CSS, JavaScript), and 1 to see the result.
• You can save your code and update your existing code.

• Supports collaborative code.
• It just starts with a simple text area where you can paste code, and click run.
• You can change the command line parameters and set the stdin before running the program. Best suited for many old languages that are not supported by new online editors, and you don’t want to install and configure each compiler for those languages.
• It supports 68 Languages.
• It executes directly from your website/blog.
• JDoodle Save the program and share as URL with others.
