Power supply

I have started on my journey to CNC, thanks to the very helpful folks
in this group. I will be using gecko 210a along with motor rated at
3.2v 2.0amps. The gecko site recomends a unregulated power supply
with a minium 24 volts. I have heard it is pretty easy to make your
own power supply but for the life of me can not find instructions or
a list of parts on the internet. Any ideas? Also where would a good
place be to purchase the required parts, preferably online since I
live in the boonies.
Thanks again,
Matt
