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 this projects, a basic multi-meter is required
