At present, the navigation list appears on all experiment pages. This causes all files to be changed when a single helpfile is added.

It will save resources if the menu can be moved to a separate home page accessible via a single click from any of the experiment help pages.

Create a framework which will enable users to remotely login and access the PSLab.

The PSLab unit's analog and digital features must be calibrated in order to make it accurate.
The ADS1115 16-bit ADC is a 4-channel, 0-3.3V ADC that can be interfaced via I2C

• Add the following features :
  • Calibrate CH1, CH2, CH3 & PV1, PV2, PV3 using ADS1115. Generate Cubic interpolation functions for each
  • Calibrate PCS using a measured Load resistor, and calibrated analog channel. Generate interpolation function
  • Calibrate CAP using precision capacitors
  • Write all calibration constants into flash memory after assigning a timestamp
  • Store raw calibration data in a client-side folder

• add schematics ,screenshots

Add schematic and screenshot

The blog is a good place to get people attracted. Documentation itself should be kept in a /docs folder in the repository. So people are able to update it.

Add relevant schematic

At present, experiment specific helpfiles are located in psl_res/HTML/ , and these will be moved to /docs/

Once the YayDoc generator has been setup correctly, setup.py must copy the docs folder to a known location, and the path must also be updated in PSL_Apps/bin/Experiments .

Just show a welcome message and a list of available functions

Create a Jekyll include for video embed for an HTML5 video player.

The present configuration downloads and installs dependencies from source in the following way

before_install:
    - curl -L http://sourceforge.net/projects/pyqt/files/sip/sip-4.16.5/sip-4.16.5.tar.gz -o /downloads/sip.tar.gz 
    - curl -L http://sourceforge.net/projects/pyqt/files/PyQt4/PyQt-4.11.3/PyQt-x11-gpl-4.11.3.tar.gz -o /downloads/pyqt4.tar.gz

install:
    - pushd sip-4.16.5
    - python configure.py
    - make
    - sudo make install
    - popd
    # PyQt4
    - tar xzf /downloads/pyqt4.tar.gz --keep-newer-files
    - pushd PyQt-x11-gpl-4.11.3
    - python configure.py -c --confirm-license -e QtCore -e QtGui -e QtTest -e QtDesigner
    - make
    - sudo make install
    - popd
...

This method is inefficient, and takes a long time to build.
Instead, python-pip should be used , for which TravisCI has a built in caching process also.

• Add backend support in views.py for adding a new user. check uniqueness of e-mail ID
• Add Frontend support
  • SignUp.html should be able to pass user fed information, and reply with the results: success/error

• Use giffer.html , and create a jekyll include file that enables the click-to-play functionality on animated gifs such as those recorded by Byzanz

The Makefile tries to build both python2.7 as well as Python3 , and this breaks Travis.
Up until this point, the makefile was not being invoked, but that needs to change because xml templates should be compiled during the build process.
Previously, compiled .py files generated from .ui files by pyuic were part of the repository.

Relevant section from the Makefile

	#cp docs/misc/build/*.html $(DESTDIR)/usr/share/doc/pslab/html
	# create ditributions for Python2 and Python3
	python setup.py install --install-layout=deb \
	         --root=$(DESTDIR)/ --prefix=/usr
	python3 setup.py install --install-layout=deb \
	         --root=$(DESTDIR)/ --prefix=/usr

The app references functions from PSL.I2C that do not exist yet, and an issue has been raised for the same.

the datatype argument should only be passed to the dataProcessor function for clarity. Acquisition and retrieval functions should only be concerned with acquiring bytewise data arrays

Possible causes:

• import PyQt4 statement was called before setting the Sip version to 2. The default version is 1

Since the Experiments App imports all the experiment apps before launching, this can be tricky to locate. Local build is executing without throwing the Sip error 💭

• add schematics for op-amp based summing junction
• add screenshots

template files ( *.ui ) are compiled by pyuic to ui_*.py files via the Makefile
These files must be generated during the build process, and not be stored in the repo, so git has been configured to ignore files that match ui_*.py
But, a lot of Apps use compiled templates that do not start with 'ui_' , and were compiled outside of the makefile. The references in these apps need to be updated, and pre-compiled templates untracked.

Make changes corresponding to (fossasia/pslab-python#55)

add schematic too

The travis build fails while trying to install pslab-python dependency . The libraries by the pslab-python Makefile are not in a virtualenv accessible path . Error:

from PSL.commands_proto import applySIPrefix
ImportError: No module named 'PSL'

It is proposed to use python setup.py install instead

Dependence of drain current on G-S voltage, and Source Voltage for an N-channel FET
add schematics, screenshots

• Is not providing accurate data
• save option does nothing . Include it.
• is plotting occupancy ratio. Should plot dust concentration.
• Include configuration options for
  • Integration time per sample
  • total samples
• missing help file

The current set of helpfiles are written in plain HTML, and are not easily editable.
It is also difficult to provide links to other resources, or insert a Table of Contents.

Therefore, there is a need to convert these files to markdown format, and set up a static site generator such as Jekyll to create pages with appropriate formatting, and user friendly cross-links

Task list :

• Convert existing help files to markdown format
• Configure URLs such that relative links in the static site built by Jekyll work properly regardless of location.

• Add schematics for series, parallel combinations
• Create a reusable include file for calculating net resistance for parallel combinations

• nosetests failed with missing dependency pyqtgraph

• Random Sampling : Study sine, triangular, and square wave inputs
• Sounds beats : Study interference of sound & the beats phenomenon using two piezo buzzers and the sine wave generators

• Precision rectifier : An op-amp based half-wave rectifier that does not suffer from band-gap limitations
• Ramp Generator : A circuit that generates a linearly rising voltage output

• Creating a sweep channel
• Specifying derived channels
• Recording data from I2C sensors
• Plotting acquired data

The following fields are needed

• e-mail
• password

Currently, the repository downloads the source of pretty huge dependencies such as PyQt4, and then proceeds to build them before proceeding to actually testing the repository.
This feels like an avoidable waste of resources and time. Is it possible to prevent re-installation of repositories each time?

Add schematic and screenshot

• add schematics ,screenshots

The present landing page at docs/experiments.html shows only a small python code snippet.

The README.md of pslab-desktop-apps can be adapted to create a suitable landing page
This page should eventually serve as a getting started guide

Sign up options should include the following fields

• name
• e-mail (Also treated as login ID) . Must be unique.
• password

PSLab remote has a dedicated repo. Therefore take out all code from this repo and close issues.

Create md docs & screenshots

Perform experiments, and record a screenshot of the expected results. Place these reference images in psl_res/HTML/screenshots so that helpfiles in the parent directory may reference them
