Want to do a bit of good this holiday season without leaving your couch or battle station? Well step right up and try your hand at Santa Claws, the charitable claw machine created by UK-based firm Liberty Games. For every toy you can maneuver to the chute, Liberty Games will donate money to Crisis, a national charity devoted to ending homelessness.

The machine is filled with special Christmas-themed stuffed animals that represent different cash values from £1 to £5. And these toys are doing double duty — after the holiday, they’ll all be donated to a good cause. In order to make this playable worldwide, Liberty used a Raspberry Pi, two Pi Face boards to interface the claw machine’s controls, and a Pi Face rack to everything together. They have the machine set on ‘generous’, so go have fun.

Has this rekindled a longing for your own claw machine? Yeah, us too. Here’s a full-size machine that runs on a Teensy.
