In This Edition:
WikiHouse, Have I Been Trained?, how QR codes work, brick toaster industrial battery, & how transistors work!

I recently started learning to play the guitar (using a £1.99 tutorial book I bought in a charity shop). Last week I made the plunge and bought my first electric guitar!
What inspired me to make the purchase was watching the super enthusiastic & talented Dagan Wilkin demonstrate lots of guitars with molto gusto on the PMTVUK YouTube Channel.
I challenge you to watch this video, or any of his other videos, and not want to learn to play! :-D
