Transistor Cheker

This is a simple circuit for identifying leads of  any transistor. It will show you whether transistor leads you connected are correct or not by glowing red and green LEDs. This circuit is done by a popular analogue integrated circuit 555. It is also small in size and cheap. This is a battery powered circuit and have long life. Here we published front panel of product. Circuit is so simple and similar to transistor tester.

In this project front panel that we published contains some wirepad or socket. It is for connecting transistors. I done it by cutting IC socket into 3 holes group an connected it on the case. By soldering it with appropriate connection i completed this project neatly.
I also used stickers to decorate the case.

Working :

     Audio signal is connected to C1 which bypasses AC and block all DC content in the input audio signal. Next section is an inverting amplifier with Input Resistance 47K and Feedback resistance 1M. So, the voltage gain is 21.275 and inverted. Then it is connected to 3 sections for filtering through a variable resistor to select the input voltage of three. Next section is Band pass filter for Bass, Normal, Treble frequencies. Its output is filtered from DC and rectified. It is connected to the base of a NPN transistor and this NPN transistor dives LEDs Smoothly. The limiting resistor in series with LEDs provide high current flow protection.
     
      All Non-inverting terminals are connected to a virtual ground network and through this idea we can avoid negative voltage to the op-amp.

The dawn of digital music is visualized in the form of lights. But now they are mostly visualized through programming techniques. Here I present a project which visualized music by Light Emitting Diodes. First of all the credit goes to makezine blog where I grabbed this circuit and published. The more introduction will available a makezine blog. Here I am only presenting this project in front of you.

There is a Virtual Ground section in the circuit diagram. That means it needs to be connected with all non-inverting terminals of op-amp. Quad op-amp IC MC3324PG and Single op-amp IC TS921 are unavailable at my place. So i replaced both of them with LM324 and uA741. For this circuit both ICs will work fine. Components packs includes this both Ics and if you want to do this project in your home, please order the DIY kits from bottom of this page.
