General
advice for building our kits or any circuit on stripboard
Components should be mounted on
the plain side of the stripboard, with the wire ends pushed through holes and
soldered with the minimum amount of solder, taking care not to bridge the gaps
between copper strips. If the copper is cleaned with very fine abrasive (i.e.
wet and dry paper) before use, better joints can be produced. Always use a small
electronics type soldering iron and electronics grade solder, and keep the bit
(tip) clean and well tinned (coated with solder). The iron can be cleaned with a
quick wipe on a damp cloth or sponge.

i.e. a resistor with Yellow, Violet, Orange stripes has a value of 47000ohms (47K)
Variable resistors, or potentiometers, are adjusted by turning the slider control using a small electronics screwdriver in the slot provided.
Circuit pins should be pushed in from the copper side of the board and soldered in.
****THE FOLLOWING COMPONENTS MUST BE INSERTED THE RIGHT WAY ROUND OR DAMAGE WILL OCCUR.****


When joining our kits, wires should be kept short, ends bared for about 5mm, the strands tinned with solder, and formed into a hook with pliers to fix them to the pin before soldering them to the pin. As an alternative to soldered joins you can use short crocodile clip leads. A set of six can be found on series one kits page.
Wire links on boards are best made with solid cored wire mounted on and pushed through from the plain side of the board.
