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
