Home About me Contact us Easy electronic projects Simple circuits Amps with PCB Power Supply

Hi,friends.
Everyone need the electronic projects that correctly works.
The collection electronic circuit to show you that not enough.
Because sometimes them may not works, so you lost times and too much money.

I need to see you happy with your projects.

Therefore, I will experiment build them to assure to you that It is really works. But this working must to use long times and a lot power. Please wait me.

Because we have more than 700 electronic projects. It may cause you difficult to find them.

I hope you will like them and come back to visit mysite again.

Best regards,
Momename

 Sawtooth wave generator circuit using UJT

Wednesday, September 11th, 2013

In the Figure 1 circuit used Q1 is UJT to connects with VR1(potentiometer), VR2 and C1. They acts as a sawtooth wave generator circuit, by C1 to charge and discharge. Then, current from the 5V power supply through VR1 and R2. This current and voltage that increase and reduce, cause Q1 generate signal. Which have […]


 DC to DC converter 12V to +/-40V using LM3524

Sunday, September 8th, 2013

This is the DC to DC converter project for converts from 12V car battery to dual voltage of +40V Ground and -40V (Available of +/-27V ; +/-30V ; +/-30V; +/-50V as setting parts) are used as power supply of 50W-100W amplifiers. When you want to increase your car amplifier. Essentially, there are 3 ways in […]


 Six sound effect generators using MM5837

Wednesday, September 4th, 2013

This is a simple sound effect generators that imitate the sound of water and wind in nature. At least 6 sounds by changing capacitance only. We use IC-MM5837 as an important device. So powerful. And budget. For example six sound effect are: 1. Rain on the metal roof. 2. Rainstorm 3. The wind in the […]


 Simple crystal oscillator 1-10MHz using inverter gate

Monday, September 2nd, 2013

This is simple crystal oscillators that provided square wave of 1MHz to 10MHz, Use an inverter gate IC and control frequencies with crystal. A oscillator or a frequency generator provide waveform out in various forms. For example : sine wave, Triangular waveform, Or square wave. The Frequency generator to control or out for a base […]


 Temperature detector circuit

Friday, August 30th, 2013

This is the temperature detector circuit in simple. can check a changing of temperature. It use LM335Z as temperature sensor IC and OP-amp TL071 for comparator IC, and Alarm with Buzzer so real easy project. You can apply them to various temperature detectors. For example Heat – cold water, and many other temperature-related well to […]


 60watt stereo amplifiers without customization.

Tuesday, August 27th, 2013

This is complete stereo power amplifier 60W +60 W without customization. Which is easy to build , sound quality, and cheap because the LM3876 works perfectly. Now. IC amplifier is very popular. Therefore has components manufacturers produce and distribution IC such as STK, TDA, and LM greatly. And often are used in Mini component and […]


 Universal tester circuit with VCO(voltage controlled oscillator)

Friday, August 23rd, 2013

A voltage controlled oscillator circuit that called as VCO, is the circuit that use voltage signal level from input to control an amount of frequencies that generate at output or the output frequency transform by voltage . The basis of a function generators circuit or an oscillator generator circuit to applied in testing a lot […]
