Harvesting Parts (if you’re
just too ghetto to buy them)
Sometimes parts can be hard to find or
just too expensive. Also shipping times can be a real killer, which
is why it's nice we live in a no-repair society. Electronic junk is
abundant and a great source of parts, as one can find all sorts of
components for free, including rare and/or expensive components. A
great place to visit is the local dump of course, although the
dump-people seem pretty strict with their garbage.
Excellent sources of parts are;
Monitors Flyback transformer, capacitors, Ferrite, Mosfets,
transistors, wire, diodes
PSUs Inductors, small components, Mosfets, diodes, PWM chip
TVs See monitor.
ovens HV cap, MOT (Transformer), HV
Stereo System Plenty of small
Disposable Cameras Capacitor
with charging system, first coil gun
Most large electronic
equipment Heavy duty components
Harvesting parts isn’t easy without
some way of mass desoldering. I actually desoldered a whole monitor
with just a soldering iron. It took a long time and cost me a
soldering tip. The parts tend to get banged up, because you’ll need
to break the board up for anything with >3 pins.
That’s where the heat gun comes in!
When using a heat gun watch the
temperature on the board and components. It gets hot fast and you
will likely burn the board the first few times, which smells
horrible. After applying heat for some time you can just tap the
board and the components will fall out. I was able to remove an
entire flyback this way, along with everything else in this photo.
Here is the result of 2 PSUs and a monitor, it only took a few hours.
