The basic principle behind a flasher circuit is to create an oscillating signal that alternately turns the output device (e.g., an LED or a buzzer) on and off at a desired frequency. In this comprehensive article, we will dive deep into the world of flasher circuits.

Customer ServiceHere is a solar powered Flasher to scare away the nocturnal animals like bats and cats from the farm yard or premises of the house. The brilliant multicolored flashes confuse these animals and they avoid the hostile situation. It is fully automatic, turns on in the evening and turns off in the morning.
Customer ServiceThe basic circuit is a Joule Thief which is designed to drain the charge in C1 to light the LED. This causes the LED to flash. After that C1 has to recharge through R3, which takes about 3/4 seconds, at which point the cycle repeats. The optional parts increase the power to the LED, and make the flash longer as well.
Customer ServiceThe basic principle behind a flasher circuit is the charging and discharging of a capacitor. When power is applied to the circuit, the capacitor begins to charge. Once it reaches a certain voltage threshold, it triggers a transistor, which in turn activates the light or LED. The capacitor then discharges, and the process repeats, creating the

Customer ServiceThe PowerSaver Flasher uses capacitive output coupling to produce brighter shorter flashes and has a much lower average current drain than standard bicore or 74HC14 flashers. The PS Flasher with one LED circuit (2 LEDs) runs all night from a 1F capacitor charged to 5.5V.
Customer ServiceIn the above regulated solar garden light circuit diagram, since the base of the left side 2N2222 emitter follower regulator BJT is clamped with a 5.1 V zener diode, means that its base voltage is fixed at 5.1 V, regardless of the solar panel voltage. Therefore, the emitter voltage of this regulator 2N2222 BJT will be always fixed at around 5.1 - 0.6 = 4.5 V. This 4.5 V fixed

Customer ServiceIn this tutorial, I will show you how we can make an LED Flasher circuit using a 555 Timer IC. This IC creates pulses of current at a specific time interval, and we will use these pulses to turn the LED on and off, hence it will work as an LED flasher circuit. The time interval of the pulses can be controlled by changing the value of resistors and capacitors used in the
Customer ServiceSolar-powered traffic systems are a viable, low-cost alternative to expensive hardwired installations. The scope of traffic applications has broadened from traffic counters to flashing beacons, to portable traffic signals. However, the baseline specifications for solar-powered systems remain consistent, i.e., three basic items: 1.

Customer ServiceBecause the circuit draws so little power I decided to power it using a small 3 Farad supercapacitor charged by a calculator solar cell. The circuit basically just uses a 3.3V (max) solar cell that charges the supercapacitor to a maximum of ~2.6v through a diode (voltage drop ~0.7v). This is important because supercapacitors have a maximum
