Certainly!
I will close this thread but leave it as a warning to novices who follow this nonsense. The article is either from someone who has no knowledge of electronics or someone who has no idea of how to take measurements. Most of it, including the values of components quoted is technically incorrect, doesn't work and cannot possibly work. Sadly there are many similar articles on the internet, written by dreamers or scammers that have no interest but to make money from advertising revenue and gain 'followers'. If you read the attachment, treat it with the skepticism it deserves and do not waste time or your money trying to follow it.
