If you visit Maplin's shop in Aberdeen you will be able to buy any number of small, inexpensive, simple electronic kits.
Each kit of parts comes with full assembly instructions. This is as good a way as any to get started in electronics.
This is a link to Maplin's kits:
Maplin > kit
For example the YouTube video mentions a square wave noise generator - a kit for that from Maplin costs just £6.99.
The VHS box mentioned in the video is simply the box into which he put the circuit. It is nothing to do with VHS.
Have fun!
The chances are that the person who will take your money is also a member of this group and can give you further guidance.
