I make a lot of amplifiers. Because I like to listen to music. And a VU Meter circuit is a circuit that I like it. In addition, it is used to display the power level of the audio, it also is beautiful. Many friends, would prefer same me. When you go to the electronic equipment […]
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 power amplifier series have disposition in circuit as OCL form is stereo system provide power driver of 14 watt / channel at load 4 ohm. Suitable for beginners thought will build the electroacoustics to listen yourself. This project use IC of The SGS company number TDA2030, which SGS said that TDA2030 is power amplifier […]
This is the Melody and Music tone generator circuit which I think is useful for adding color in the electronic work is good, Can be applied to sound an alarm, or assembly electronic projects very well. Examples circuit that I suggest, is a switch for adjusting the sound more, it is not boring, these circuits […]
Near the Festival of Happiness.Christmas and New Year’s Day. My son was thrilled with the gift of friends in the village.Music Box is a scientific inventions that he wanted made because he thought it would impress the recipient. And it is easy made electronic projects. Cheap as well. I suggest three circuits, which featured various […]
Have you ever had a problem with the front door bell or not? Are, I am boring old buzzer. When used with directly AC line.Danger of leakage power in the heavy rain. And, doorbell quality is very expensive. I think we try to make yourself better, strange sounds a unique. Cheap equipments. And high performance. […]
I like planting trees, because trees are more useful to us. However, I always have problems with moisture content of soil,Each plant needs water is not as same. Watering or soil moisture is not good. May cause damage to our trees. With these problems, I think the electronic system to solve this problem. For example, […]
In electronic instrumentation is needed.One friend of mine, once said that a good tool. Not need to be expensive. It is important to use enough. Today I will try to collect circuits Simple Voltage Indicator. by LED and Zener diode You look into the concept. Although is small circuits. But it might make circuits great […]
