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

wow, that looks great!

any low voltage and overtemp protection? Rough ball park on price?

This would be well worth posting on the mtbr DIY lights forum as triple XM-L lights are becoming quite popular there. Plus, there's a guy prototyping a housing that would suit this down to the ground - I'd expect demand to take off a fair bit once that's ready as it'll be the simplest and brightest build around.

Looks and sounds incredible, Pilot! Any idea on expected price?

NICE!

I've never seen such a nice combo for sale before - what an excellent job with that high efficiency! I love it.

Same as the others - price estimate on 1 kit?

doh! you know, I completely didn't make the connection between this and that mahoosive 4x4 light some crazy guy was building from scratch :) That makes it even more interesting..

Awesome board! Looks like you've incorporated many key features that are highly desirable.

What tint are the XML's?

Will watch this closely....

Price? Tint?

I'll take 5 of whatever you come up with.

Very nicely done !!!

This is awesome news!

What MCU are you using, an AVR?

just some questions from the guy making the 35mm housings (Zemike), here's the link

"Never saw an XM-L on FR4 substrate.

Matt, can you ask several questions on that forum?
1) what is the LED/heatsink temp on full power ?
2) minimum order quantity for a machine assembled module ?"

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.

PPtk

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.

PPtk

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!
