405nm help

[bluuray]

hi ok so im new to lasers and i rlly wanna build one i gathered up and read allot of info abt them and how they work and what i need to build em
so i started looking for parts...
driver:
Micro-Drive V3 adjustable driver (assembled) - $13.00 : rkcstr.com, Micro-Drive and laser diode electronics

diode:
PHR-803T HD diode in heat sink 405nm !!! HIGH POWER !! [PHR803T] - $14.99 : StoneTek Electronics, Your Laser Parts Store

i got heatsink host and module already covered..(not ordered yet though)

then i found out i needed a dummy load thing to set the current on my driver or something?? (need some explaining how to do it) (simple words please )
k so i found this one :
Laser driver dummy load (test red or blu-ray) - $9.99 : Modwerx Shop

the host im planning on getting is just a flashlight with heatsink ofcourse but it uses 3 AAA's and i wanna know if i could just use 3 * 1.5v ones to get 4.5volts or change the battery holder to 1 AA or 2 AAA or w/e

and i wanna know exactly how to connect the driver to the battery holder..

im buying goggles and soldering station tooo

well hope someone can clear things up for me..
btw im 14
