Parallax just completed their Hack the Halls Contest. Ben Kenobi made a project called How the Grinch Stole Christmas, the user aims a laser at a Christmas scene and shoots things up. Sensors detect if a hit was made and gives the player some feedback. Looks like fun!
“Materials – I picked up a few cheap Christmas decorations at the dollar store and walmart as well as cotton balls, glitter (don’t ask) and 9V batteries for about $10. I threw everything on top of a pizza box and had used other cardboard boxes for things. I had to pick up two servos, LEDs, photoresistors, a speaker, joystick, various resistors and wire from radioshack. I had used my $50 gift card I’ve been holding on to for a year. The laser was bought off of amazon for like $5. The BOE was picked up at the beginning of the semester.”
