- Supplementary Construction notes
- ==========================================================================
-
- To make life easier this project can be built without recourse to
- expensive parts or equipment. The luxury of custom PCB designs has been
- abandoned in favour of the hobbyists' friend: stripboard.
-
- For those of you not familiar with this fine invention, stripboard
- consists of a plastic or resin-fibre board, perforated with regularly
- spaced holes. On the underside of the board are a number of parallel
- strips of copper, running the length of the board, and each incorporating
- one row of the holes.
-
- By breaking the copper tracks where necessary, and linking between them
- using pieces of wire, it is possible to make quite complex arrangements of
- conducting material. The legs of the electronic components can then be
- pushed directly through the holes and soldered to the tracks in order to
- construct whole circuits. Believe me, it sounds far more complex than it
- actually is.
-
- Stripboard is readily available along with the other components. The
- supplier I recommend (for UK readers) is Maplin Electronics. Their
- catalogue is available from most large newsagents, and they have a number
- of shops dotted round the country. Maplin order codes and approximate
- prices are included where appropriate.
-
- You'll need tools to cut the board itself and the copper tracks. For the
- former, a good old fashioned Stanley knife or heavy duty craft knife will
- do. Maplin sell a plastic handled version (FS98G, £1.05) which will do the
- job admirably.
-
- For cutting the copper tracks you'll need another tool. Whilst you could
- theoretically get away with using the craft knife here, you'll find life
- much easier with a drill bit. A 3mm general purpose or metal cutting bit
- will do - but not a wood or masonry bit. If you haven't got one kicking
- around, borrow one as you'll only need it for a day. Failing that, Maplins
- sell them (FV60Q, £0.76) as well as a custom tool for the same job (FL25C,
- £5.99) which is ideal if you intend to do a lot of work with stripboard.
