<x if x=the number of times DYI wasn't/isn't awesome

Basicly none, the motor will let out the magic blue smoke, and as we all know, magic blue smoke is what makes "lectrickal" stuff work.

The actual compressor should handle it, this is a very good implementation of such a system.

Yeah all electrical things run on smoke :P im an electrical/mechanical engineer student by the way :)

yeah I was thinking about throwing a way way more powerful motor in there and seeing how things go.. maybe a high torque brushless rc motor..

but as I said in the edited post, free air con units :D :D

I'd gear it down, look for 180RPM, the pipe running to the schrader might fail, might pay to epoxy it into the chamber via some fittings. (Yes I'm a hypocrite)

I've finished a cert II electrical pre app and hold an advanced amateur radio license, I also know what percentage of a capacitor is charged after one TC (I don't use emoticons on principle, but the sentiment is there)

If there is anyone in the brissy area who know has some good info on how to setup an aircon compressor, they just might be a free one in it for you :D

Cutting the copper pipe in a portable aircon unit - bad choice :(
turns out theres gas is there :?

So I took the angle grinder to one of the copper pipes on the air compressor and out came all the gas that was in there.. needless to say I got out of that garage very quickly..

So heres the question, is it safe to cut the other pipe now? Has all the gas been released from the first pipe I cut?

I don't believe it is toxic at all. But it is bad for the ozone layer.

Alrighty..
So iv pulled the aircon unit apart and Im trying work out the wiring.. I have it all figured except for one part..
So coming from the wall socket, I have a Green and Yellow wire (ground), a blue wire (positive?), and a brown wire...
green wire obviously mounts to the base of the compressor, blue wire runs via the cap then on to the the compressor..
but this brown one is the one that is tripping me up.. The brown wire runs into one of these
http://doc.chipfind.ru/omron/g4a1ae.htm

then out of that comes a red wire which runs to the compressor. Obviously it is a relay of some sort, but do I need it, and what does it do?

Here is what I tried to explain above

Rekon I can just eliminate the relay and run the brown wire straight to the compressor?

...

then you'll know the brown is live while the blue is neutral ;)

I agree that eliminating the relay should work, however I know next to nothing about 'lectricity :D

Haha so far we have only been working with more computer based stuff (microprocessors, PLD's, programming etc etc).. I think your thinking of an electrician :P

Hmm well Ill take out the relay and see if it runs :D
