Analog Space Invaders with human controller


[fidepus] put together a pretty nifty version of the game Space Invaders. This is an analog version that involves an ink and paper based display system.

He printed out one piece of paper for each different enemy, mother ship, laser beam, and player vehicle. The human-based controller is used to move the pieces in all directions. When it comes time for a row to move downward, the pieces are removed from the game grid and relocated to their new position using a scotch-tape-actuator.

We think the most successful part of this hack was [fidepus’] ability to integrate sound effects into the controller system. The human-based controller puts out mono sound with a “pew-pew” for laser blasts and a “dirnk-dirnk… dirnk-dirnk” for the enemy movements.

Although there is no code nor a schematic provided, we think this system shouldn’t be too hard to reverse engineer.

Exercising to space invaders


[Matt] sent in this cool final project he did for his Computer Engineering course. They built a space invaders clone, where the player has to physically move back and forth to move the ship, and jump to fire. The game is projected on the wall, with a camera mounted below it, facing the player. The player, wearing an orange vest, is tracked for the movement and the firing. They also included a blue tooth heart rate sensor with the ultimate goal of using this data to vary the game difficult, but didn’t end up getting the code in. You can see a video of them testing it out at the end of his post.
