As can be seen from the previous page, the parts are supplied in 6 bags. This is to allow the project to be build in stages, and it also allows components that could be mixed up to be kept separate. For this reason the instructions advise that the contents of one bag are fitted completely and checked before the next bag is started.
This is good advise for both beginners and experienced constructors alike.
The instructions are downloaded and printed out to a 26 page document. Care must be taken to download the revision of the manual to match the revision of the kit to be built. The version being built here is V 1.1.
As with all construction, a tidy bench free of unnecessary parts is important to a successfully build. Once opened the parts should be placed in a tray , this way it is unlikely they will be knocked off the bench and lost.
The parts should be cross referenced with the packing list in the bag to ensure all parts are present. Resistor values should be checked with the aid of a magnifying glass as the components are quite tiny. A DMM should be used to verify values where uncertain.
It is easier to check before the component is inserted than afterwards, as desoldering can cause damage to the pcb as well as the component.
Once a component is fitted it can be marked as such on the instruction sheets. This way if disturbed you know where you got to with the build.
Setting Up The Bench
A range of quality pliers of various sizes are needed to bend the legs of the components prior to fitting. The small green handed ones are the most use for this purpose. Pointed side cutters are needed to cropping the surplus legs from components prior to soldering.
As an experienced constructor, I prefer to install say six components, crop the legs and solder them. Then check the board for missed joints before fitting more parts.
Soldering before cropping the leads can cause damage to the joint, especially if the pcb is a single sided board without through plating.
These are my personal preferences, and not written in stone. If a method works for you then stick with it.
