Where can I do this?
Are the costs to get started high or low?
Would I be doing this in a group, in a couple, or on my own?
Are there physical requirements that might make it difficult for me to participate?
Dexterity likely required
So what's it all about?
How old-school do you want to get here?
Electronics as a hobby covers everything from tinkering with a homemade radio, to fixing up household appliances like broken lamps and kettles, to assembling a DIY computer.
Before you grab your soldering iron and start taking your TV to pieces, however, please make sure you are safe and are not in danger of electrocuting yourself...
