How to wire 12v dc case fan to 1x9v and 2xAA batteries? Answered
I'm planning a project using a 12vdc case fan to inflate a plastic bag for a school project.
I have located a 9v battery clip and a 2xAA battery holder and was wondering how i'd go on with wiring them together.
I was also wondering if it was possible to reverse the polarity, thus creating a vacuum effect. If so i'd like to have a 3 prong switch to control the case fan.
I appreciate any help you could provide me. Thanks!
