Many garage door openers are not very secure but there are still thousands of codes that need to be transmitted. If these codes were being entered manually it would take a long time to go through all the possibilities but of course we could just use a small processor to run through the combinations. Samy used a kids toy that had all the required hardware to do the task,
Have a look at the great video of this Vinyl LP under an Electron Microscope. Using an Electron Microscope isn’t as easy to use as a normal microscope, in this case the vinyl needed to be metal coated to be viewed.

 Zhiyuan Teo and Mohit Yogesh Modi made this iPhone Gesture Control for their ECE 5760 Final Project. Their system uses a camera to look for certain gestures to control the docked iPhone. The current version uses a green square as the item that is being tracked and there are 4 video regions that are being watched. With a bit more work a hand could be tracked instead of

Ben dips the money into the ammonia, lets it dry and repeats the process. Each time this process is repeated the bill shrinks slightly. Sure makes for an interesting looking bill but be prepared to have a conversation piece that you won’t be able
