In this text file I will talk about places to get parts and components for electronics. First of all, Find a box or container to keep your parts in. This helps keep your collection in a easy to find place.
I work on the following rule: Don't throw stuff away. Just because it no longer works, doesn't mean it doesn't contain useful parts. Things like old VCR's computer PSU's, Kitchen appliances. TV's, basically anything electronic contains parts that will work in other projects. If it shits the bed, put it in that box of yours and when you need parts look inside your junked electrical stuff before going down to your local electronics store to buy them. Chances are you will find something that will work for that particular application.
So what useful things are inside household appliances:
Microwave oven: High voltage transformer 110/230 - 2000 volt out, HV capacitor, HV diode, 110/230v lamp, motor, fan, assorted wire.
VCR: Motors,resistors, capacitors, transformers, diodes, transistors, wire, rotary transformer in the video head which can be used in certain projects.
CRT TV: Flyback transformer, diodes, resistors, heat sinks,capacitors,leds.
Computer PSU: MOSFETS, transformers, diodes, resistors, wire, ferrite inductors, heat sinks, rectifiers.
Basically there are usable parts in most household appliances.
Good places to find cheap or free appliances include:
Second hand shops
Kerb sides on rubbish collection day
Once you build up a collection of parts it becomes easy to build things without having to go out and buy what you require.
