Hi everybody, after reading for some time I'll make my first post now.
I want to build myself a flashlight. The only not debatable item is the body, for everything else I already have ideas but the result is completely open.
the light should be powerful
budget: would be nice to keep it under 50$ but depends on the options I get for the money
things to consider:
- I live in germany
- I study physics, know how to solder (even smd) and can get access to nearly every electronic equipment
what I want: a nice discussion and after that a list with: led(s), optics, a driver and batteries to buy/make
I'm also interested in links to information I missed in my previous searches
body: metal tube, 2mm thick, its 250mm long and has 35mm inner diameter
(for the curios: its Darth Vaders light saber hilt
led: what I have in mind: one XP-G, multiple XP-Gs or one MC-E (or corresponding leds from another manufacturer)
optics: dunno, maybe a simple reflector?
driver: 3 modes, no fancy modes
driver type and batteries: should run on rechargeables and easy obtainable normal batteries, maybe 3 D-cells (3.6 - 4.5V) because they fit so nice into the 35mm body, but I dont have any experience with driving leds from batteries so I'm totally open to any concept
I hope this is the right way to start the thread here, if not correct me please
thanks in advance
