Find your breadboard
This is where you’re going to connect your electronic components to form a circuit.

Inside the breadboard, these holes are connected to each other, so you can make loads of different circuits!
Connect the power rails
Find the long black and red wires and connect the power rails: negative to negative, positive to positive.

Make sure to push the components as far as you can into the breadboard.
Find your integrated circuit chip
An integrated circuit (IC) is a pre-made mini circuit.

This one is an oscillator. Electricity enters in one steady stream, but leaves in pulses.

Each of the pins has a different number, that's how you identify its function, so it matters how you connect things to it.
Connect the IC to the board
If you're having trouble connecting the IC, slightly bend the legs inwards by pushing them against a flat surface like your table.

Tip: closely follow the numbers on the breadboard, that way your circuit will be exactly like the one in the image.
Connect the IC to the power rails
The red wire is where the power goes in. The black wire is where it exits.
Using the wires, connect the pins to each other
Find your resistor
A resistor slows down the flow of electricity.

Looks closely at your resistor.

The colours indicate how much they slow electricity down.

This is measured in Ohms (Ω). It’s like meters, but for resistors.
Carefully bend the legs of your resistor
Connect the resistor
The resistor is symmetrical with same length legs. This symmetry indicates that it does not have polarity, so can be connected into the circuit either way round.

Because it has long legs, resistors stick out from the board.
Find your capacitors
A capacitor is like a little bucket, it stores electricity and, when full, releases it back to the circuit.

Capacitors come in different sizes and can store different levels of electricity. This is measured in Farads (F).
Connect the capacitors
Find your 470K potentiometers
Potentiometers work just like the dials on car radios, ovens and microwaves! Look around your house and count how many you have.

In reality, they're resistors you can adjust — turn one way to increase the resistance,turn the other way to decrease it.
First, find and connect the blue and red wires
Push the potentiometers into place
They need to be flush to the board. They might need a good push!
Find your electrolytic capacitor
This is a different type of capacitor that can store a bigger charge.

See the different length legs?

This asymmetry means it has polarity, and you have to connect the long leg to the positive side of the circuit.
Connect the capacitor, but remember the long leg
Find your 2K2B Potentiometer
This is exactly like the other potentiometers, but with a much lower resistance range.
Push the potentiometer into place
It needs to be flush to the board. It might need a good push!
Find your speaker
The speaker translates an electrical signal into sound.

Pulses of electricity cause a magnet to push the speaker back and forth.

This magnet is attached to a cone made of a flexible material such as paper or plastic which amplifies these vibrations, pumping sound waves into the surrounding air and towards your ears.
Pull off ends, twist wires and separate
Connect the speaker wires to the board
The speaker has no polarity so it can be connected either way.
Find your battery holder
This connects a 9 volt battery to power the circuit.
Connect it to the power rails
Plug in a battery, turn the dials and ROCK OUT!!
Your synth should sound like this (make sure you turn the dials).
Not working?
Find your acrylics
Everything in your kit is usable, even your box!

Use it to make your DIY Synth Kit portable.

The colours of your acrylics may be different.
Put a piece of tape in the battery spacer
Stick the spacer in the box
This needs to align with the battery space on the acrylic.
Disconnect both the speaker and battery holder
Your circuit may look different.
Place the speaker and battery holder on top of the casing, then thread the wires from under the hole
Cut the last piece of tape in half
Place each half in a side of the box
Secure the plastic casing to the box
Peel the film from the breadboard
And secure it to the casing
Re-connect the speaker and the battery clip wires to the breadboard
Reconnect your battery and make everything nice and neat
