Assembly hints

1. Assembly (Skipping this can lead to troubles ! )

Ok, so we have your attention. These hints will help you to make this project successful. Read them carefully.

1.1 Make sure you have the right tools:

• A good quality soldering iron (25-40W) with a small tip.

• Wipe it often on a wet sponge or cloth, to keep it clean; then apply solder to the tip, to give it a wet look. This is called ‘thinning’ and will

protect the tip, and enables you to make good connections. When solder rolls off the tip, it needs cleaning.

• Thin raisin-core solder. Do not use any flux or grease.

• A diagonal cutter to trim excess wires. To avoid injury when cutting excess leads, hold the lead so they

cannot fly towards the eyes.

• Needle nose pliers, for bending leads, or to hold components in place.

• Small blade and Phillips screwdrivers. A basic range is fine.

For some projects, a basic multi-meter is required, or might be handy

1.2 Assembly Hints :

⇒Make sure the skill level matches your experience, to avoid disappointments.

⇒Follow the instructions carefully. Read and understand the entire step before you perform each operation.

⇒Perform the assembly in the correct order as stated in this manual

⇒Position all parts on the PCB (Printed Circuit Board) as shown on the drawings.

⇒Values on the circuit diagram are subject to changes.

⇒Values in this assembly guide are correct*

⇒Use the check-boxes to mark your progress.

⇒Please read the included information on safety and customer service

* Typographical inaccuracies excluded. Always look for possible last minute manual updates, indicated as ‘NOTE’ on a separate leaflet.

Assembly hints

1.3 Soldering Hints :

1- Mount the component against the PCB surface and carefully solder the leads

2- Make sure the solder joints are cone-shaped and shiny

3- Trim excess leads as close as possible to the solder joint

REMOVE THEM FROM THE TAPE ONE AT A TIME !

DO NOT BLINDLY FOLLOW THE ORDER OF THE

COMPONENTS ONTO THE TAPE. ALWAYS CHECK

THEIR VALUE ON THE PARTS LIST!

Connection

Incandescent lightbulb or halogen lightbulb:

connect the lightbulb to the output R, G or B.

Place a wire jumper for R4, R5 and R6.

 Polarity is not important. 3A /channel max (36W@12V).

LED-strip with common anode (+) :

Connect the common anode to the (+) of the 12VDC power supply.

Connect the cathode (-) of each colour to the (-) of R,G or B on the K8088.

Place a wire jumper for R4, R5 and R6.

 Max. current consumption is 3A/channel.

LED:

 LEDs require a series resistor (R4, R5 or R6)

Determine led voltage drop (Check manufacturer datasheet).

Rule of thumb: red: 1.7V, green: 2V, blue: 3..4V).

Next, check required LED current.

Example:

Red LED, 1.7V drop, required current: 20mA

Resistor calculation: (12V-1.7V) / 0.020 = 515 ohm (choose nearest value,

e.g. 560 ohm)

Resistor power rating calculation: (12V-1.7V) x (12V-1.7V) / 560 = 0.19W

(choose a 0.25W resistor)
