12v vacuum pump

[Trick]

I purchased a very cheap vacuum pump (12v 500ma) from ebay. Still waiting for the delivery:

To make it work, I also bought a 120V AC - 12V DC adpater (2A version.):

It also comes with a small adapter for wire connection to the vacuum pump.
Planing to make a wood frame to mount these two items together.

I also bought a vacuum gauge, a ball valve and some fittings. Altogether less than $40.
Downside is that I have to wait for a long time for the delivery from China.
There are some videos in Youtube for the mini vacuum pump.

I will use the assembly to do degassing and racking.

I've used ATX computer power supplies for all sorts of stuff needing 12V. Usually yellow/black lines on the power supply are 12V. Cut off the rest of the lines or tape them up.
12V rail can usually supply over 10A.
Find an old scrap computer, rip out the power supply, and check the specs on it to see if it does at least 8A on the 12V lines.

Most power supplies even have an on/off switch on them.

Last year I wired up my father in laws rotisserie on his BBQ to run off one.

Thats a brilliant idea, you can get all sizes of atx power supplies for computers, im sure you can find one that will run 8 amps, large servers are bound to draw 8 amps.

Just took a picture out of my old computer, 12volt rail will do 17 amps

The only problem with these is that it's rated at less than 2 amps. The pump draws 8 amps.

The first one that I cited can handle 8 A. The 2nd can handle more.
