vader-esque saber build

[cbjones1]

forward voltage 1.85, forward current 30.... as per the website.

The very first circuit will be a 'test' just to have a play with a single LED and then with lessons learned and skills gained, build from there. I wanted a 150 ohm resistor and not a 15 ohm one >.<

You're right!
I didn't scroll down to red....lol.
Was looking at white.

I *may* have done the same a few times

I'll take your lead on the appropriate resistor type. Will source one and purchase. I hope my 15 ohm resistor comes in handy sometime >.>

He's already got the resistor figured out for the ONE LED he's got. We're figuring out what to come up with for more LEDs now.
Plus, that's based on 6v. We may end up with a completely different power scheme.

that's the website I used funnily enough!

I've now got 100 of that spec resistor on the way courtasy of eBay. Hopefully its a common spec for LED work

It's not.
Fwd currents and voltages vary between LEDs.
You've got a 10mm, too--the MCD rating comes into play--how bright it is.
And--whether, or not you use more than one LED in series.
should be okay for a single LED, but it would be best to get a variety.
Resistors are dirt cheap--a few cents each.

Yeah this was a couple of quid for 100 of the suckers.

Maplins order came today. Lots of useful things. I forgot to add the wire on however. The led lens looks wonderful. Due to the depth of the internal emitter piece and the height of the LED I need to use a washer to elevate it. Only a couple of mm though. Will look cool. Managed to gut the electronics out of it too and luckily the bulb holder/internal emitter is luckily held in by a screw! Took a few pictures. Going to get the grips on tonight as I'll be able to slip the clamp on over the top end. Will do a pics post when done.

Appropriate parts missing sourced and ordered on eBay! (Pp3 connector for battery box and wire)

Progress! As I can get the emitter shroud, screws and emitter innards out I thought id attach the grips! All seven on. Not quite perfect but I'm happy with a first attempt. Pretty much eyeballed it. Surprisingly comfortable in hand too! I have. However managed to bond the end cap on I think, no biggie though. Will wait for superglue to cure properly before putting some real effort in getting the end off! Pics now added!
