MR string minus resistors

[Jedi-Diah]

Hi Erv,

If you build a led strip version of CF, will it have different output settings? I assume it would for different led strip configurations (partial series/parallel or all parallel). Any chance you could have a max output of 2000 mA (for parallel setup)?

Thanks!

that will be a specific board, ledstrip driving differs to luxeon driver (which has a true current regulation)

Apologies for the necroposting, but since this is even more relevant now than it was in 2008, and Erv's LED-Strip board is close to completion, I would like to ask if anyone has done any more experimenting with using a MR/Hasbro LED PCB as a frame for a high-brightness LED strip. I'm sure we all have dozens of those MR/Hasbro LED strips lying around, waiting to be put to some meaningful use.

well, i'm not a fan of string blades, but i've actually started considering it, if there's a good solution from Erv... bridging the resistors is a definite must with these though, either way.

and the string blade i would have to build is a golden string... >_> and maybe a double spaced string of cool white for FoC... so unless there's a yellow MR blade already out there... yeah...

Thanks, Azmaria. One aspect I'm particularly interested in is the possibility using high-brightness LEDs with a Force FX board. In other words, just replacing the LEDs (and, presumably, removing the resistors).

[Azmaria Dei]

with how they're wired in, i don't think just replacing the LEDs will be too easy... i might be wrong though.

If you get some solder tweezers like are used for reworking SMD components, you might be able to melt both sides at once and pull em off.

[Azmaria Dei]

or you could just solder over the resistor and bridge it that way.

[Skottsaber]

I meant for desoldering the LEDs....

[Azmaria Dei]

ah yeah. are they soldered in where you can get to them though?

Yes. One leg on each side of the strip. I don't think you need anything fancy to get them off and put new LEDs on.
