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 ?"
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).
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.
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?
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!
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?
