This was our final lab project for Vanderbilt's biomedical instrumentation class. The idea is that a simple sensor could be implemented to control a quadriplegic vehicle. Our approach to this problem was by utilizing an accelerometer that could be easily attached to a hat. The vehicle would then be controlled by the degree of tilt on the accelerometer as the user tilted their head in the desired direction of travel. In the case of our project, we used an RC car as our proxy in place of an electric powered wheel chair.
Is your cat sad? Are the hundred's of toys you buying not satisfying your cat needs? Well look no further, the Jerry 2000 will solve your issues and this is how to build it!The Jerry 2000 is a simple idea, it is a small box where a mouse will be sticking out, as our cat will be approach it two sensors will sense the cat within 20 cm and pull back the mouse will a pulley system made with a servo.

Fochica, forgotten child in car alert, is a no hassle, low cost and extensible system that helps prevent forgetting children in vehicles.Kids who are left alone in cars are likely to suffer a heat stroke with dire consequences. People think this will never happen to them but in reality, cases like this happen over and over again every year. Why not use technology to make sure you don’t forget your kids? Fochica’s mission is to prevent forgetting children in vehicles and thus save children’s lives.Fochica™ is comprised of a Fochica open hardware, open software, Arduino-based device that is installed in a car and a Fochica app that is installed on the driver’s smartphone. Sensors monitor whether the child car seats are occupied or empty and send the data to the device. The device communicates with the app via BLE passing the information to the driver. When the driver’s smartphone goe
This project is designed using normally-closed reed switches connected to doors and windows and additional passive infrared (PIR) motion sensors to detect movement of a burglar or an unwanted intruder in your home. The security system can dial up to two phone numbers to alert you. It can also send text message to one of the numbers.

That’s right, the robot I teach you to make this time is the BB-8 in the Star Wars: The Force Awakens. Ever since the first official trailer was released in October, the adorable BB-8 in its peculiar design has attracted a large number of fans and its popularity is comparable to some main characters. Of course, it itself is a leading character who played many parts in the film. At the world premiere in Los Angeles, BB-8 also‘rolled over’red carpet as one of the major characters.
