This project is installed in a car, to modify a brake light into flash. Using a small number of pieces of equipment, so it is easy to build, consists of CMOS IC and power transistors etc. The rear brake light is warning lights to the behind car. Add Caution while tracking. This flashing brake light […]
We like to collecting the electronic circuits with PCB layout as ideal of building the Easy electronic projects, under different scenarios.
The projects are mostly old but still works great. Suitable for use or to study.
Now, We have a lot of articles(over 600 circuits). So, difficult for find the circuit as you need. It is a pity if you close this site without the great experience.Recent New Posts
This is a Simple if signal frequency generator using CMOS CD4011-CD4040-IC and crystal-3.579 MHz. In the event of AM radio repairs, basic tools that are usually found the IF signal frequency generator is used to determine the function of various sectors. Which these circuits are often used transistors, built frequency. But we use innovative circuit […]
A trembling sound buzzer circuit is create a kind of ring circuit that provide a strange sweetness of general bell. It use all transistor so easy to builds and cheap, suitable for bedroom or a private room good or may be adapted into a bell. Listening to children play leisure. In addition melodic sound then. […]
This is a bass booster that use transistors as base. It is designed to increase a low frequency of audio on cheaper than ICs or normally circuit. since use each channel only 2 transistors together with resistor and capacitors approximately ten parts only. In circuit will be have a potentiometer trimmer 10-50K act as adjusted […]
This is the circle 10 LED running light as another kind of string light circuit. Which is running light on circle each one step beautifully and can adjust speed as well. The working principle From circuit will see that we use two ICs. Which is IC1-NE555 as timer IC with a widely used general. In […]
