Need help with my first project... and it's a large one

    I am relatively new to electronics and microcontrollers, but fairly experienced in programming. I have project I am working on that requires the following components:

    power supply that can power all of the following...
    programmable microcontroller (full package)
    a laser diode driver (8.2V, current draw around 1.3A)
    4 bipolar stepper motors (10V, 500mA each)
    a strong computer case fan (7-12V, 0.5 to 1A)
    photo sensor input (photointerrupter)

    There are so many different options out there, it is a little confusing. What do I need to make all these work together? The parts and circuits must take up as little room as possible, and keeping cost low is nice. I need everything except for the laser diode driver.

    What I "think" I want to use for that:
    Prewired Modded 1.5A Microboost Driver For 445nm Didoes

    Close Alternative:
    FlexModP3 driver (adjustable and more versatile, but also more that I could mess up)

    Thanks in advance for everyone's help and suggestions

    if you get a power supply that can output... up to 12-15V at 5 amps (6-7A if possible)

    you would be able to use one model for everything, the only reason I say 15 is just to have a little more wiggle room with the voltage.

    Thanks for the reply. I've had some time to look around the internet and learn some stuff, and everything is coming together quite well. Hopefully, I'll be self-sufficient from here on out.

    Perhaps a PC power supply would do.
