Universal Robotic Gripper

There are a lot of different kinds of robot grippers (end effectors). The most common strategy when designing a robot hand is to try to replicate the human hand. However, in 2010 researchers at Cornell University and University of Chicago developed a unique approach. They created an amorphous gripper that was able to mold itself to the object that it wanted to pick up. This kind of gripper is much more versatile.

In this project, I am going to show you how to make your own DIY universal gripper for your robots.

Spy Camera Hack

Being able to hack and modify random objects is an essential skill. Budget and time constraints often make it necessary to build a project using only the materials that you have at hand. Here is a simple example.

Let's say that you are a spy and you need to get a video recording of the secret documents being handed off to an enemy spy. You have a pair of video sunglasses. But a large pair of dark sunglasses would look very suspicious indoors. So you need to quickly modify them so that your hidden camera can be used in a variety of situations. This shows how you might do that.

Inside a computer you can find a wide array of objects that can make a compelling piece of jewelry. Since computers are constantly updating, it is usually easy to find old hardware to take apart. Also each computer that you disassemble will likely have different parts that you can use. This project gives you a few simple examples of how to turn computer parts into jewelry.

Remote Controlled Balloon Pop Prank

Balloons are great for simple pranks. You can pop the balloon and scare someone, or you can fill the balloon with water and soak them. These are some of the simplest and most basic pranks that you can do. But you can always make improvements on an old classic. In this project, I am going to show you how to pop a balloon remotely. That way you don't have to be anywhere nearby when it goes off. Pranks are always better if the victim can't figure out who did it or how they pulled it off.

All you need to do is attach a small needle to the wheel of a remote controlled car. When the remote activates the car, the wheel spins an the needle pops the balloon.

Control Appliances With Your TV Remote (and an Arduino)

Most of the buttons on a remote control are never used. So why not use them to control appliances and other electronics around your house. In this project, I am going to show you how to use an Arduino to decode the signal from your remote and use it to make an outlet switch that can turn your electronics on and off.

When you are done, you will be able to control lights, fans and even your coffee maker with your TV remote.
