This is a re-publish of a poorly done instructable that I posted a while back.
Transform an aquarium air pump to create a weak vacuum
This type of pump will only produce a weak vacuum but I use it for positioning electronic components and de-soldering applications.
You will need a tetra whisper Aquarium pump, a Philips screwdriver and about 5 minutes.
Step 1: Open the pump
On the bottom of the pump you will fins 4 Philips screws. Remove these with a number 2 Phillips driver.
Flip the pump over and lift off the large blue plastic cover.
