Need to brush up on ring final circuit testing? This video is available to Trade Skills 4U students as a revision aid, however we thought we would make it available for all. This was created by one of our tutors hence why it's a little rough around the edges but still great content. Remember if you are not trained or experienced in electrical installation don't try to install at home or anywhere else for that matter.
The basics of linear voltage regulators - what they do, how to wire them up, and where to find them. Then I give a basic example of how to build a 5V supply that can power USB powered gadgets. 5 volt regulators: http://www.amazon.com/exec/obidos/ASIN/B00H7KTRO6/afromods-20 This video builds on material covered in my tutorial on building unregulated power supplies: http://www.youtube.com/watch?v=cyhzpFqXwdA Webpage: http://www.afrotechmods.com/ Twitter: http://twitter.com/Afrotechmods Facebook: http://www.facebook.com/Afrotechmods/
