How To Make an Amplifier

Amplifiers are used to increase the power of audio waves. In engineering, there are many types of amplifiers and many uses for these. The most common use for the amplifier, however, is for increasing the sound in musical instruments or for increasing the sound in home entertainment systems. There are amplifiers that can be purchased from most hardware shops and electronics shops. But, you can also create your own. You can purchase the parts separately, or you can also purchase kits that will allow you to create the amplifier all by yourself, but without having to buy each resistor separately. This is often a cheaper alternative. Here are the steps that you should follow.

  • Transistor base. First of all, you will need to connect a Darlington transistor to your breadboard. Both of these can be purchased in most hardware and electronic shops. In your breadboard, you will see some markings. You need to fit in the transistor on exactly the j29, the j28, and the j27 marks. By doing this, the wires from the transistor radio can be connected to the 122 and 127 marks that you will find on the same side of the breadboard.
  • Voltage. After you have attached the transistor base, the next step is to split the voltage towards the amplifier in half. To do this, you must have a 100,000 ohm resistor that is connected to a battery. The battery should be around nine volts and should be in contact with the resistor from the positive side. Connect the other end, so that the voltage from the battery will be divided evenly.
  • Resistors. After you have prepared the voltage in the battery, take the ohm resistors that are connected to the battery and then fix these onto the breadboard. Again, look at the grid on the breadboard and make sure that the ohm resistors are connected to the F26 mark by the negative section of the voltage battery. The positive section should be linked to the F34 mark on the grid in the breadboard.
  • Wattage. Afterwards, you will need to connect the ohm resistor to the G20 mark, all the way to the F28 mark. Doing this will make the divided voltage in the battery more stable. When the voltage is stable, you will be able to clear out the distortion from the amplifier. Next, take another resistor that is pegged at 50 ohms and use it to control the flow of watts in the amplifier. The amplifier should only receive one watt at all times. The 50 ohm resistor should be linked to the I34 and the I33 so that the wattage will be kept at a constant one.
  • Speakers. Once you have finished configuring and controlling the wattage, the final step is to connect the speakers to the breadboard itself so that you will be able to hear the amplifier. The speakers need to be attached to the J33 and the F29 marks on the breadboard grid.

In just a couple of minutes and while following these steps, you should be able to create your very own amplifier from scratch.
