All-in-one printers feel like a necessary evil. You can go through a long period of your life without needing to print or scan someone, but the one time you do, you're really out of luck unless you have a friend who owns one or your local library has units you can rent out. Fortunately, the all-in-one printer's tyranny may be over, as someone has created and programmed their own document scanner for a fraction of the price. And best of all, you can make one too.
Forget paying for scanners: this genius made one for cheap with a Raspberry Pi
