Nerf sentry gun with image recognition

Here’s another hacked Nerf Vulcan rifle. This time it is an automated sentry gun. You must present it your badge, if no badge is found, you are assaulted with a fiery storm of small nerf darts. All encounters are logged and a photos are kept. This was a final project at Cornell, and for once it wasn’t ECE.  This was for CS1114. They did a pretty good job with the tracking, now they need to add some more interesting voice options to it.

8×8 RGB small form factor toy

Here’s a cool tip, sent in by [Martin]. He has put together this very compact package for an animated 8×8 RGB LED array with a tiny footprint. It is controlled by an ATMega16 powered by 2 small lithium cells. While it may not be quite as small as the space invader button, it seems to have a bit more animation horsepower.

Magic wands for Disney

MAGIC

[NRP] sent us a few of his projects. The most notable of the bunch was a school project funded by Disney. They were to make some kind of interactive entertainment for people waiting in line for rides. They decided on a wand style interface. Each wand has an accelerometer, an IR LED for tracking, an XBee unit, and a few buttons for interaction. They wrote some custom games and a multi person white board to test it all out.  You can see those in action, along with a space themed pong game in the video after the break. Even though this was funded by Disney, you can still find all the source code and schematics, available for free.
