Arduino Parking Assistant

Those of us who have small garages know the frustration of parking a little bit too far in or a little too far out and not being able to walk around the vehicle. We recently bought a larger vehicle, and it has to be parked perfectly in the garage to walk around the front and back. To appease my frustration I decided to design a device that would allow me to park in the exact spot every time. I love working ...

THIS FORCE CONTROLLED ROBOT GRIPPER IS LESS LIKELY TO BREAK STUFF

While robotic arms can handle a wide variety of tasks, the specific job at hand will have a major influence on the type of end effector used. For sorting ferromagnetic parts an electromagnet might be enough, while for more accurate location a mechanical gripper could be employed. If you’re working with particularly delicate objects or in concert with human beings, it may be desired to have a force controlle ...

Air pressure sensors in smartphones

Today’s smartphones utilize a wide array of accelerometers, gyroscopes and various other sensors in their designs. Relatively unknown is the barometric pressure sensor, which measures air pressure. These sensors are currently being integrated into premium-grade smartphones, but are also becoming more common in mainstream phones or wearables such as fitness trackers and Internet of Things (IoT) applications. ...

Circuit provides cold-junction compensation

The accuracy of any circuit or system that uses a thermocouple to determine the temperature of a process is limited by the accuracy of the method used to perform cold-junction compensation. In a thermocouple measurement, two wires of dissimilar metal join together at the "hot," or measurement, junction. The isothermal termination of the thermocouple wires provides a second "cold," or reference, junction. Th ...

Plant Communicator

Ever wished you could talk with your plants? Story Introduction As the English poet William Wordsworth once said: "Your mind is the garden, your thoughts are the seeds, the harvest can be either flowers or weeds." Keeping your plants alive can be quite the challenge as they are very bad at communication. One way to keep them happy is to bring your plants with you, but maybe you don't want to lug around with ...
