There are a lot of accessories out on the market, yet more often than not you can pull a MacGyver and create your own version, as demonstrated by this toilet roll iPhone amplifier.
Created by Cameron Kenley Hunt, the toilet roll iPhone amplifier is cheap, easy and actually functional. Although you have to wait for a roll of toilet paper to be finished before you can attempt this DIY project, its simplicity makes it well worth the wait.
