hey there.

So id like to build my 1st pcb. however im not sure how to go about it.

what i have to start with is

(2x) 3.7v 900mah li-ion batteries.

i need an output voltage of atleast 12volts
to run a small project moter.
with a pot to control voltage/speed

is this possable

Why not get a 6V motor and make your life much much easier?

because the motor isent actually a rotating motor its a coil setup.

Can you get hold of more batteries?
