This paper aims to develop a low-cost stroboscope, which consists of an optical equipment capable of generating flashes of light at different frequencies , allowing to measure the rotation velocity of machines and contributing to maintenance processes in the industry. This device is based on the stroboscopic effect, a visual event that occurs when a continuous movement is presented by a series of samples, generated by flashes of light. When the frequency of the rotation movement is the same frequency of light pulses, the process will appear stationary. Based on the high cost of the commercial stroboscopes, it was developed a stroboscope prototype based on the Arduino platform, LED technology and 3D printing with an open hardware and software. The final prototype went through calibration and validation processes, achieving a performance very similar to a commercial instrument.

A series of demonstration experiments devoted to the relativity of translational motion in inertial and non-inertial reference frames is proposed. We recommend a simple algorithm for the formation of the ability to transform coordinates, speeds and accelerations during the transition from one reference system to another system moving translationally relative to the first one. Stroboscopic photographs of an experiment are given. In this experiment, a ball flies after a shot from a platform moving along a straight line uniformly or having a constant acceleration.

We have added two improvements to a self-luminous LED stroboscope (a flashing point-like projectile developed for introductory mechanics): downsizing by replacing heavy and risky batteries with a compact and safe capacitor of several Farads (a so-called Super-C) and wireless control via ordinary IR (infrared) communications. Consequently, the device allows the real-time visualization of velocity vectors to be performed using a web camera under ordinary room light. In this paper, we describe the technical details and also a typical demonstration by reference to our 15 min show at Osaka Science Museum that analyses the swing speed of a tennis racket on the spot.

A LED stroboscope with computer control of light flashes

Abstract: We propose the use of a laptop with a program generator and a transistor power amplifier to control the frequency, duration and amplitude of the LED stroboscope flashes. Examples of the stroboscopic photographs are given.
