This flashing lights circuit can be used as beacon. The assembly consists basically of two blinking steps that commands two light bulbs. With the help of P1 you can adjust the flashing frequency between some limits. Circuit diagram : Flashing Lamp Lights Circuit Diagram There are 2 parts for the circuit, the second one works the same way as the other but with the help of a wire bridge or a switch you can choose different operating modes. A bridge between M and 3 means: 2 independent blinks. If there is a bridge between M and 2, then the lamps lights alternatively with a frequency that can be adjusted with P1. And finally there is one more possibility for M and 1, where the lamps blinks at the same time. The flashing lights circuit works with voltages between 3V and 15V.  The lamps voltage must be 2/3 of working voltage. R5 and R10 are chosen so that the lamps are about to light.

The series of emergency lights on this one is a series of emergency lighting is quite simple and not difficult to make.  Frankly this circuit is not my own design, but at least this series can add to your collection of electronic circuits. The circuit is actually almost the same as the battery charger circuit, it's just that in this emergency coupled switching circuit as a circuit breaker when the circuit load is connected to the supply voltage of 220 volts or in other words on the charging position. Meanwhile, when the voltage of 220 volts is lost (PLN lights off), then automatically switches the load switching circuit and turn on emergency lights, where the supply that is used is derived from batteries that have been installed in stand-by position. In a series of emergencies over the use of LED as a lighting load emergency. And indeed these days we find a lot of emergency lights that are sold in the market that use LEDs, but the LED is used instead led carelessly but has led a gl...

As a keen cyclist I am always looking for ways to be seen at night. I wanted something that was a novelty and would catch the motorists eye. So looking around at my fellow cyclists rear lights, I came up with the idea of 'NITE-RIDER'. NINE extra bright LED's running from left to right and right to left continuously. It could be constructed with red LEDs for use on the rear of the bike or white LED's for an extra eye catcher on the front of the bike. All IC's are CMOS devices so that a 9V PP3 battery can be used, and the current drawn is very low so that it will last as long as possible.

The author gave his partner a radio controlled (RC) model car as a gif t. She found it a lot of fun, but thought that adding realistic lights would be a definite improvement. So the author went back to his shed, plugged in his soldering iron, and set to work equipping the car with realistic indicators, headlights, tail lights and brake lights. Lights Control for Model Cars Circuit Diagram The basic idea was to tap into the signal from the radio control receiver and, with a bit of help from a microcontroller, simulate indicators using flashing yellow LEDs and brake lights using red LEDs. Further red LEDs are used for the tail lights, and white LEDs for the headlights. Connectors JP4 and JP5 (channel 0) are wired in parallel, as are JP6 and JP7 (channel 1), allowing the circuit to be inserted into the servo control cables for the steering and drive motor respectively. The ATtiny45 micro-controller takes power from the radio receiver via diode D1. T1 and T2 buffer the servo signals to pr...
