Some hints for standard precautions in the field of electronics in general and PCW's in specific
- do take time to study the construction in order to be able to reconstruct;
- never work on an appliance with the mains still connected. Leave an electric appliance untouched for a while after disconnecting from the mains...
- avoid static electric charges from your body or from surroundings like e.g. carpets - discharge before and during work
- always isolate connections in such a way that they are resistant to wear and/or heat
- do not repeatedly switch the monitor on and off, as this is bad for the Cathode Ray Tube
- do not touch integrated circuits or unknown electronic components, unless wearing anti-static gloves
- use a Volt meter on cables only when they are not attached to integrated circuits or other electronic equipment
- the worst things that can happen concern the monitor and the complicated power supply of the PCW. The monitor should not be touched at all and the power supply should be treated 'gently': a short circuit results in the failure of a barrier diode (something like a fuse), that is difficult to obtain and to replace. Do take note that the internal power supply is not very powerful. When multiple devices, interfaces, a mouse, Masterscan and the like, have been connected, an expert should be consulted prior to mounting an additional drive when fed by the internal power supply. An external, stabilised supply should cost about EUR 15, so don't spend too much time evaluating this risk...
Do not let these warnings prevent you from DIY'ing on your PCW. After all, all of the projects shown have been tested and photographed in working order...
