Lad hacking his iPod so it can run Spotify
The iPod was a great gadget that could play lots of music. However, the hardware quickly became quite obsolete after the iPhone and the Android headphones began to appear and could play countless more songs than the iPods could ever do.
A guy named Guy Dupont liked his 17 year old iPod so much that he hacked it so it could connect to Spotify. To achieve this, he had to replace basically everything inside the iPod to make room for a Raspberry Pi Zero W which he connected to the iconic click wheel.
Not quite worth the effort maybe but definitely a fun project.
