At night, city streets are filled with flickering lights. This light fascinates and attracts the attention of everyone. This effect is achieved using a special device - a stroboscope. It is often used for some technical purposes, for example, for cars, as well as in other areas. The circuit of this device is not so complicated, so you can make a stroboscope with your own hands.
Historical background
The stroboscope was invented in the 19th century by the Austrian scientist Simon von Stampfer. A similar device at that time was called a phenakistiscope. This device consisted of two spinning disks: pictures were applied on one, slots were made in the second. During rotation, the light, falling through the cracks, created the impression of a independently moving figure. Simultaneously with Stampfer, the Belgian Joseph Plateau made the same discovery and made a stroboscope with his own hands from cardboard discs. The invention of this device marked the beginning of film projection.
Using the strobe light
A device such as a stroboscope is used inseveral areas. For example, in scientific research of processes of a periodic nature, taking measurements of amplitude movements and others. In addition, this device has found application in medicine as a strobolaryngphone for people with speech impairment.
In automotive technology, the device is used to check and set the initial ignition timing. LED strobe lights are installed on the radiator and bumper of the car to attract the attention of drivers on the road.
It is also widely used in outdoor advertising, entertainment venues, discos and other fields.
Types of stroboscopes
There are several types of this device: these are base, baseless and superstrobes. Superstrobes can be seen from a distance of three kilometers, while other types of these devices are visible only within one kilometer.
Schemes of these devices are currently available in different types, but they are not so complicated. Making strobe lights with your own hands is quite simple, having at least basic knowledge of electrical engineering.
Production of the device
Depending on the purpose of the device, the principle of its manufacture is slightly different. We bring to your attention the easiest way on how to make a do-it-yourself stroboscope for LED illumination of the gear knob on a car.
To do this, you will need an LED lamp, a knife, a soldering iron and glue - it is best to use a glue gun. Next, we act according to the plan:
- Remove the gearshift knob, clean the top part of the glass from the paint.
- After that, polish it with felt with a special paste.
- Make a hole in the handle to connect the power lamp.
- In the handle we make a recess for the lamp, removing unnecessary details.
- Using a soldering device, we connect the wires of the diode and the handle.
- Fix the lamp on the handle with glue.
- Assembling and installing the handle.
The use of such a device facilitates the operation of the car. And if you make a stroboscope with your own hands, you can save a lot on buying a ready-made fixture.
