As requested, 3 XM-L Driver/Emitter module DIY

When you say that we have to do the soldering, exactly how much soldering is that. Also how much will it cost? :p

I'm curious about the machine assembly as well, considering I'm better at soldering, but don't trust myself to do all of that tiny stuff (especially doing the LED).

Glad you like it!

Yes and Yes. I'll have a better idea on price by tomorrow - details then.

Once I have it more finalized, I'll post over on that forum. Thanks for the suggestion!

Thanks! Yeah, that was kind of the plan. The swiss army knife module.

That's the beauty of a "Kit" - They're whatever tint you want them to be!

If I start manufacturing them, I'll likely offer a cool U2 and a Neutral T6.

PIC. Microchip offers the PIC Controllers in higher temp ratings than AVR offers the TINY Series. For instance, the TINY13A in the DFN package is only rated to a max of 85C. The PIC Part I've selected is rated to 150C. Additionally, the PIC is physically smaller. For what they have to do in this application, it's 6 of one to half a dozen of the other anyway.

He'll be plesantly surprised by the performance of an XM-L on FR-4. I promise.

1) Completely 100% dependent on the heat-sink. MCPCB, FR-4, Platinum - doesn't matter what the emitters are mounted on - it's the heat sink that has to dissipate 30 watts.. I can't answer the question, unfortunately.

2) Unsure just yet - I haven't even got the kits shipping yet. Details will be provided if/when I'm prepared to offer a fully assembled module.

For the 'kit' - I mean all of it. You'll get a bare circuit board. Not for the faint of heart, and I don't pretend that it is.

Pricing to be announced soon.. I'm still wrapping up a few details.

A few people wrote to me and asked about mechanical prints and 3d models - I'm assuming to assist in fitting this into an enclosure.

Rather than send it to everyone privately, I'm just going to post a link to the files here.

How low is the low voltage protection? Would this light engine be able to run on 2 x 18650's?

I've had a look at both your drawings and the CUTE-3 datasheet, but nowhere can I see how far the leds are from the center or the board. Will the DRY reflector fit this light engine?

Thnx

Incredible! 8-|

thanks, I posted your reply on the thread over there.

I've certainly learned a lot this morning about MCPCB and FR4 substrates :)

I think a lot of people, both here and on mtbr would be very interested in a complete assembled board. Heck, even I would start thinking seriously about it and I already have a stupidly bright set of DIY lights. The thought of soldering the bits on myself would give me the heebyjeebies though, even soldering AMC7135 chips onto a board isn't my idea of fun!

Absolutely not. Minimum input voltage = 9V. The three emitters are wired in series and this module has a buck-converter, not a buck-boost.

The LEDS are arranged at 0 degrees, 120 degrees, and 240 degrees on circle that is 17mm in diameter. Thus, the polar coordinates are

8.5mm, 0
8.5mm, 120 and
8.5mm, 240
with the center of the module being 0, 0.

I don't have a DRY, not do I know the measurements of it's reflector, so I have no idea whether that matches or not.

Subscribed.

The bike light DIYers are watching...

Yeah, i'm getting that vibe from a lot of people - looks like I WILL be offering this as an assembled module. The kit will still be available (and available first) for those who want to do it themselves, but I'll go ahead and plan on having these machine assembled..

For assembled modules, I'm going to have to pick a max of two or three different XM-L Tints/Bins.. What's everyone's preference? If you had to pick two XM-L tints/bins to be available - what would they be?

PPtk

Oh, damn... Now I have to behave :)

I'll be looking for the machine assembled versions.

What would a dual version look like, is there a way to gang the controls together for two units?

I'm going to wait for the sticker shock before getting excited ;)

Now, this could function quite well in an automotive application, correct?

@PilotPTK: I think 1A/1B/1C or sth. like that U2 and 3C T6 would be the most requested. Can you provide a low voltage protection at 13V?

yeah, it's easy to forget when you're very proficient at something that others can be less so :)

this is all very tempting though, I may have to unsubscribe from this thread before my will completely fails!

Welcome to the monkey house, phburns!
