/* 
 * Compile and flash this firmware onto a ESP32-S2 and then use a seperate micro USB connector 
 * to connect the S2's Pin 19 to USB D- and Pin 20 to USB D+ (and of course +5V to +5V and GND to GND)
 * 
 * It will appear as a 'USB Mouse' in Windows/Linux/Mac, and move the mouse every 30 seconds or so
 * that you are always online/green. The ESP's LED will flash briefly when this occurs.
 *
 * Even better, buy and ESP32-S2 Mini with USB-C and put it into DFU mode: https://www.youtube.com/watch?v=YPX2nlr-ySU
 *
 * If writing firmware to an ESP32-S2 Mini using Arduino IDE. Make sure you have 'USB CDC On Boot' set to  'False'

bbc-news-comments-scraper

A simple python script to scrape comments from one or many BBC News articles. This was tested to collect the Brexit related discourse posted on the BBC News website.

How to use

1. Go to a BBC news article with comments you're interested in, and view the source of the webpage. Alternateively, in Chrome, right-click on the 'View Comments' button and select 'Inspect'. For example: http://www.bbc.co.uk/news/uk-politics-eu-referendum-36306681

2. Look within the HTML and for the string 'forumId=CPS' (without the Single Quotes). After 'CPS' there will be a number, copy this number. For example '__CPS__43250035', then copy '43250035'

3. Edit the 'articles' list in the python scraper code, add the relevant Article title and number as required. For example:

Get-ChildItem -Recurse -File -Include *.jpg,*.JPEG | Foreach  {C:\<CHANGE_THIS_PATH>\jpegoptim --max=80 $_.fullname}
