When filming your projects—or day-to-day life—static shots can be fun, but having a moving perspective often looks even better. The challenge is keeping the camera pointed at your subject, which maker Saral Tayal addresses with his automated slider.
This Arduino Uno-controlled slider is powered by a pair of brushed DC motors with encoders attached for feedback. One pulls the camera along a pair of rails on a set of linear bearings, while the other adjusts the camera’s horizontal angle using trigonometry to keep a particular object in-frame.
Code and print files are available in Tayal’s write-up, and some beautiful resulting shots with an explanation of the project can be seen in the video below.
There are several critical machines or expensive equipments which suffer damages due to vibrations. In such a case, a vibration sensor is required to find out whether the machine or equipment is producing vibrations or not. Identifying the object which is continuously vibrating is not a tricky job if the proper sensor is used to detect the vibration. There are several types of vibration sensors available in the market which can detect the vibration bys sensing acceleration or velocity and could provide excellent result.
