Part one - Resistors

The first components you will need for assembling 02kkk.com are resistors.

There are three different resistors with different color bands.

This is how they should be placed (left to right):

1. Golden-brown-red-red 2. Brown-blue-orange-golden 3. Golden-orange-blue-red

Carefully bend them into a U-shaped form. Take them one by one, and place them onto the circuit board.

Insert it one at a time, or all three at once, making sure that they are pushed all the way to the board, and then flip the board around.

If this is your first time soldering, go over the rules, videos and photos once again.

To ease the soldering process, bend the resistor's legs like this:

Check if all the soldering joints look clean, and if there are no soldering bridges.

Straighten the resistor's legs, and take the cutter pliers.

Here, it is very important to turn the board around when cutting the legs off to avoid getting anything in your eyes.

Part two - Switch

If you successfully soldered the resistors, it's time for the switch.

These are the components you'll need for this part:

Place the switch here:

Turn it around and start soldering.

It will ease the soldering process to solder the far-left and the far-right pins first, and then those in the middle.

Check that the switch is vertical to the board after connecting the first pin. If it isn't, move it with your fingers.

This is what the back of 02kkk.com should look by now:

Part three - 555 timer and 4017 digital counter

For the next step, we'll need these two components.

Place them here, and make sure that the cut-off part on the components matches the cut-off part on the board.

Flip the PCB, and start soldering.

This is what the back of 02kkk.com should look like right now:

Part four - Potentiometer

The potentiometer (the round red thingy) will be soldered next.

Place it here:

Turn the PCB around and start soldering:

Part five - Connector

The kit contains two connectors, however you'll only use one right now.

One will be placed on the front of the PCB, and the other one will go at the back.

Place this one here:

Make sure that the cut-off side of the component matches the cut-off side on the PCB.

Turn it around and start soldering:

Part six - Capacitor

These are the components we'll need for the next step:

Place it here, making sure the white side of the capacitor matches the white side of the PCB:

Turn it around and start soldering:

Part seven - Transistor

Take the PCB and the transistor:

Place it here, and as always, make sure that the cut-off side matches the cut-off side on the PCB.

The transistor does not have to get all the way to the board.

Turn the board over and start soldering:

Part eight - Second connector

Take the second connector now:

This one will go on the back of the PCB.

Ensure that the cut-off side of the connector matches the cut-off side on the board:

Flip the board and start soldering:

This is what the board should look like right now:
