Instructable is very well written and has all details for successful project.
I kept project affordable,
1) reflector is printed then covered in foil.
2) LEDs are standard 5 mm.
3) Used a standard 200mF capacitor
4) Lens cover is cut from clear PET packaging material
Flashlight works well, the supercap will smooth out light better.
