First Build and need some help

[Rimshot15]

Good afternoon/evening everybody,

I've been on this site for the past few months working on a build and I think I have the majority worked out.
The main sticking point however, is that I am in no way an electronics person. So, I honestly don't know what extras I need and not sure on a power supply either.
Only going to be one led currently, and no sound. Might eventually add sound at a later date but figured I'd keep it simple.

• Screw on LED blade holder style 4 (Tap hole 8-32 for thumb screw)
• 4" Double female threaded connector
• 2" Double female threaded connector
• MHS Extension Blank Style 3
• MPS Pommel style 10 (Powder Coated) (Tap hole 8-32 for covertec)
• MPS Clip
• MPS Insert style 6
• Machined button for Covertec clip
• 8-32 x 1/4" socket head
• Double ended male threaded connector style 2 (Powder Coated)
• MHS choke style 1 short (Powder Coated)
• Rebel Star LED & MHS Heatsink Module
• 16mm Anti Vandal Latching White Ring Switch
• Brass Bezel for Illuminated switches
• LED Trans White Show blade 1" OD

There will also be the machining for the switch itself, either on the MHS Extension Blank Style 3 or the 2" Double female threaded connector. Also, the emiter shown might change since it's currently outta stock and no clue when it might be back in.
Here is an image of the basic layout via the builder:


Thanks for any and all help in advance
