Make your own LED Stroboscope (for a safety system)

**The Ultimate Guide to Creating an Intruder Scaring Powerful LED Stroboscope**

As someone who's interested in home security, you're likely looking for effective ways to scare off intruders on your property. While a siren is the obvious choice, a bright blue stroboscope light can be just as intimidating and even more useful in certain situations.

**What is a Stroboscope?**

A stroboscope is a device that consists of a light source and a driver circuit that periodically illuminates the light source for a very short amount of time. This creates an optical illusion that makes objects look like they're moving in slow motion. While this effect can be useful in a nightclub setting, it also has scientific applications.

**The Stroboscopic Effects**

In a demonstration, a motor with a marked disc was attached to its rotor and let spin at an unknown rpm. When stroboscope lights were created out of high-power LEDs, MOSFETs, and function generators, the disc appeared to be frozen in time. This effect is known as the "Stroboscopic Effects" and occurs when the pulse frequency of the stroboscope matches the rotation frequency of the motor.

**Building a Stroboscope at Home**

To build a stroboscope light at home without using a big and bulky function generator, there are two main options: microcontroller routes or 555 timer circuits. Both can be adjusted with potentiometers to achieve the desired pulse time and frequency.

**The Final Product**

After testing both circuits and soldering them onto a perfboard, the author created a stroboscope light using three blue high-power LEDs, each with its own heatsink and mounting system. The lights were powered by an overkill boost converter that can output up to 90 volts and 1500 watts.

**The Result**

As you can see in the demonstration video, the stroboscope effect is definitely there, but the light source appears dimmer due to the short illumination time. However, this can be compensated for by increasing the voltage and current flow.
