1. Assembly  (Skipping this can lead to troubles ! ) 
Ok, so we have your attention.  These hints will help you to make this project success-
ful.  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 f 

                  fine.
