 LM324 Quad OP-AMP

Friday, June 28th, 2013

The LM324 IC is derived high popular that used in many circuit diagram. Which is a package of four operational amplifiers (OP-AMP) that can be powered by a battery or other single-polarity supply(positive and negative only) over a very wide voltage range. The four op-amps are installed in a single 14-pin package. You can use […]


 Mini 40 watt audio car amplifiers using HA13001

Friday, June 28th, 2013

From this 20watt Integrated Amplifier project. Some people say that expensive and want the main amplifier only. I recommend this project, it had a budget of only 5$. and is the main amplifier. They have size of power to speaker is 40 watts and use voltage of power supply is 12 volts so can apply […]


 How to install CCD camera sensor with VHF sender

Wednesday, June 26th, 2013

The CCD camera sensor is device that have very useful. This project has small size. But quality is a lot good. We can install with Television easily through the video in terminals. and connects to the video signal modulated to To send a broadcast RF signal is explicit is better. This project can be adapted […]


 55 watts rms classic OTL integrated amplifier that you build easily

Monday, June 24th, 2013

From the previous project, some people say that Not suitable for a small party. Because of soft and does not durable. So I highly recommend this project are The classic OTL integrated amplifier that power output 55 watts. The its feature is loudly than other circuits and watts are equal. the speaker has durability and […]


 The 30 watts rms integrated amplifier projects using cheap transistors.

Sunday, June 23rd, 2013

When a friend of mine wanted The integrated amplifier that is smaller. For listening in a small room. Must have good the sound quality. Low noise and cheap. I often recommend this project is a featured There are power 30 watts RMS. Using all transistors. Do not select the IC Because my friends do not […]
