Hello,
My name is Cody and i am currently doing year 12 at school.
as part of my course i need to create a practical "thing" from initial idea through research and protoyping to come out with a final product.
I this endeavour and need to make a what i see as basic curcuit with very little prior knowledge of electronics.
i have 6 fans and i am not sure which will be used in the final project:
2x 120mm 12V DC 0.36A
2x 12omm 12V DC 0.16A
1x 120mm 12V DC 0.25A
1x 140mm 12V DC 0.25A
I require the circuit to run all fans from wallpower 240V AC ( no idea how to find the right power supply)
they need to have an on and off switch (i think i can do myself)
and a way to turn up and down the rpm of the fans ( i assume change the power going into them with a resistor???)
If i can id also like to have the unit have a plug so that the powersupply isnt always connected to it and can be replaced for unplugged from it so some sort of plug.
Would anyone be able to help?
