Health and Safety

All of the projects contained in this book can be built with the minimum number of small hand tools in a kitchen type workshop. Care should be taken when using these items especially tools with sharp cutting edges.

Two of the projects contain spinning discs which should be shrouded where possible to avoid contact with humans or pets whilst turning.

Many of the latest LEDs come with warnings with regard to eye damage so ensure a suitable diffuser is placed in front of these when viewing.

Our main concern is with mains supply voltages. Most of the projects requiring a single dc source may be run off encapsulated supply typically supplied with computer auxiliary equipment, these provide a cheap safe low voltage dc supply. Should you choose to use mains transformers included in your own 'home brew' power supplies ensure all exposed mains wiring is insulated and good safe wiring techniques are observed. All mains supplies should be fused accordingly. If you do not feel confident using mains voltages then use batteries or purchase commercially available units.
