Picture of Build  a small Electric Fan from a scrap microwave oven
Hi There, 

Did you know we can salvage lots of item from an Old Microwave Oven? Yes we Can!

First, there is that large transformer which we  can convert to an electric welding machine.

Second, there is a small gear motor ( that turns the carousel) where we can use for a slow speed projects like a mirror ball motor..

Third, a microwave oven has this heavy duty blower fan, where we can use as an mini desk fan, this is where our instructables is featured..

best for those who are into renewable energy, this project does not consume lots of energy..

follow on....

Hi profpat! It's a nice project.
I also removed the spareparts of an old microwave oven. I want to use the fan as an exhaust fan (smoking issues). Yet, I am not sure about the voltage. Do I need any additional transformator, resistance etc. before I connect it directly to the 220V house plug?
Cheers.

Hi There, if the microwave is 220 VAC, it is a good chance the fan inside is also 220 VAC.. but if the microwave is 110 VAC, you may need to use a stepdown transformer to use it on 220 VAC mains.

i already made one last year using a helping arm and a testube holder. i replaced the motor with a 12 small motor just to avoid insulating wires etc because 12v is way to low to get a shock from this small project

you can also use the geared motor of the rotating tray to turn a whole bbq chicken.
