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
