lol....another newb question

[jash1]

i must be blind, dumber than a rock or something.......wha exactlly do the buck pucks do.....do the run from the boards or from tge batt pack.....?

[Kasri Deodene]

Bit of a noob here myself, but i think they restrict and maintain the current flowing through them. They push the same current through when they can whatever state the batteries are in, thus your LED keeping the same brightness for as long as possible.

Sorry if i got it wrong, and please correct me if i did :) all a learning experience for me aswell.

lol thanks either way.......i know k2s want 1500ma and have read about them using 2 700ma buckpucks in line......i would use a MR board for sound only.....i wanted the Clash and Lock also power up and down....so ive got a full plate...

Think of it as a "fixed spigot"...

You know the gun attachment on a garden hose? You can vary the amount of water coming out, right? Now imagine an attachment that only lets so much water out - regardless of hose size or pressure.

That's your puck: some let out 700 units of water, some, a 1000... you just have to work with what you have, that's where the x2 700mA idea came from...

Just to help you out, you don't wire them in line, you wire them in parallel. Arm on Fire posted a great picture of how to hook up two 700mA pucks here:

I'm running the same setup with a green K2, and it works great. Noticeably brighter than running through a resistor, and much more efficient.

In electrical lingo, a buck transformer reduces to output of a given input. Whereas a boost transformer increases the output of a given input. Industrial buck transormers are AC to AC reduction units and do not change the frequency of the incoming power. The BuckPuck is a special type of transformer and is a DC to DC convertor that adjusts the output voltage to maintain a constant output current. So basically, as the power in the battery drains, the Buckpuck uses more voltage from the pack to supply constant current to the LED. Hope this helps.


In the picture below, the box on the bottom left of the picture (with the orange label on it) is an industrial buck transformer designed to reduce 250V AC power to 221V AC power. Try to fit that one in a saber.

Ace,
*puts finger under shirt and points*
Hand over the CNC Mill or the Lightsaber Gets IT.

[Novastar]

OMG... that is one *SSIIIIICCCK* CNC.

Boy... you're not kiddin' around, Ace! Orbital all the way!

Actually that CNC mill is almost 30 years old. It originally had a reel to reel tape drive for programming (for you young whipper-snappers, some old computers required punched tape strips to program - with each line of punching on the tape corresponding to a single character of the programming), but it now sports a new computer with flash drive and USB capability.

The mill is not alone, she has a sister too.

Ever work with Punch cards? One way to get back at some one you really hated was to shuffle them. That's worse than killing younglings. Ha ha ha

[Novastar]

Whoa. One word.... SECURITY!!!!!!

Keep dem girls under lock and key, dey needs da chastity belts. Then again... who's strong enough to steal 'em? Hehehhehehehee :)

Sweet, Ace, suhhhhhhwheet.

Ace that sure is a Beauty, actually when I worked at Odin Forge, all our Mills we manual no electronics at all. OK I must admit I have never used a buck puck and I understand the functions and advantages but here is the big question how well do they work with NIMH Rechargeable Batteries, I currently am running my Cree-5 off of 4 Nimh AA's which is 4.8Vand I noticed that Tim recommends a min of 5V?

BWAH-HA-HA-HA! :D

I was slightly less of a bastard... I'd take exactly one card, and move it exactly seven cards forward or backward in the sequence. Didn't matter as much; in my programming heyday, it was already an antiquated technology - we only used it because my school couldn't justify the expense of upgrading their old tech just for student projects.

You really need a higher voltage with the Buckpuck because of the way the circuitry works. In addition to supplying a fixed current output, they also supply a fixed 5V output. So without at least 5V input, they can't supply the 5V output. The spec sheet also calls for a minimum of 2V higher input than the forward voltage of the LED. But, if it's working for you with 4.8V, I wouldn't worry too much. I think the input requirement is more for the 5V output anyways.
