Synthesizer – Assembly
For this to work, your body will be part of the sinthesizer electrical circuit. Do you want to know how?
Lets invent your own!
To find out how to assemble the Synthesizer you can guide yourself through the video or follow the steps below.
Step by step
Take the breadboard that already has the integrated circuit in place to help you.
Place the switch on the breadboard as in the PICTURE. The switch has two rows of three pins.
Make sure that these rows are arranged horizontally when placed on the breadboard.
Now, put the LED as in the picture!
The LED legs are not the same. They have different lengths. The largest is the positive pole and the smallest is the negative pole. In this case, the longest leg of the LED must be in the first column that connects to the integrated circuit and the shortest in the line to the side.
Place the white wire on the breadboard as in the PICTURE.
Take a resistor and bend it’s legs. Place it on the breadboard. Pay attention: one of the legs should be on the left end of the white wire and the other should be on the smaller leg of the LED.
Take the other resistor and bend its legs. Place it on the breadboard as in the PICTURE.
One of its legs should be in line with the third pin of the switch. The other must be aligned with the second pin of the integrated circuit.
Place the speaker on the breadboard as you see in the PICTURE.
The black (negative) wire must be on the resistance column and the white wire. The red (positive) wire should be at the bottom right of the breadboard.
Now, the electrolytic capacitor (the one that looks like a cylinder). This capacitor, like the LED, has one leg larger than the other. The smaller leg should be in the column of the red wire of the speaker, and the larger leg should be in line with the third column of the integrated circuit.
Place the ceramic capacitor on the breadboard. One leg should be in line with the resistor and the white wire. The other must be aligned with the second pin of the integrated circuit.
Place the orange wire on the breadboard. You have to bend it to go over the integrated circuit.
Place the blue wire on the breadboard.
Place one of the colored wires with the stripped tip on the column of the third pin of the integrated circuit, below.
Place the other colored wire with the stripped tip on the column of the third pin of the integrated circuit, on top.
Place the battery in the holder.
Connect the battery holder to the circuit. The black wire should be on the column with the resistance, the speaker and the white wire. The red wire must be aligned with the switc central pin.
Press the switch. To test the circuit, take the bare ends of the colored wires, and place one in each hand.
If the LED lights up and the speaker makes a sound, you can move forward!
Glue the breadboard to the respective location of your Synthesizer, removing the film that is at its base.
Glue the speaker.
Glue the battery.
Attach the ends of the wires that are stripped with self-adhesive aluminum tape to the support: one wire on the right, the other on the left. Make sure that the bare ends of the wire are well covered by the tape.
Turn on the switch. Touch the aluminum tape on the right side with the fingers of the right hand and the tape on the left side with the fingers of the left hand. As soon as you do this, your body closes the circuit.
Can you hear the speaker playing?
