All early Vinhnguyen(famous CPF moder) mods were don with AA adhesive. But they were applied very thinly and under hard press on classic cree leds(xpg2, xml2).
The problem with osram leds is that you probably canāt give them hard enough pressure that will squeeze excess off AA and stick it firmly to pill for better heat transfer cause it will start making contact with pill anyway and puuf! I tried that kind of pressure on 4715as and poof happenedā¦ Method I use now for Osram IR are gentle circular moves, and only pressure is pressure from tweezers so I actually feel when AA starts spreading under dtp board. I donāt see or measure any performance drop on that kind of builds but they are only up to 2A.
@l.i.
Yes, the AA layer was much thicker than it would have been if I could just press it down firmly, it shorted if I did that. Perhaps someone will manage to get the layer thinner still without shorting it, but in my case with resulting heat sag the Flat Black looses the competition with the dedomed XP-G2. I doubt even if the heat sag is better than if I used a non-DTP board.
The trick will probably work much better in a mod with one of those chunky Maxtoch boards: more surface area to transfer the heat, and if the host allows lapping the upside of the pill so that both surface are nicw and flat, you can make a nice thin layer of AAA.
I can imagine that a AAA layer can be made thinner than Kapton tape and then, AAA is at least designed to transfer heat better than average, while Kapton tape AFAIK is not designed for heat transfer at all.
I have no clue what AA or AAA stuff is or even why it's being discussed, but before we get to AAAA I thought someone, somewhere might be interested in the MT03 info and mod?
Sorry Tom for ignoring your MT03 work :innocent:
From the beginning Iām not at all into the Haiklite flashlights (donāt like the chunky designs), but considering that it is a rather new brand and seems to be founded by enthousiastic and knowledgable people, it is a pity that they do not have their production method and QC under control. Among the other faults, a ledboard that is not flat on its shelf is an easily avoidable (flattening the shelf should be the very last machining step) and unforgivable blunder because it directly affects the performance in such a high powered light.
XHP70.2ās with that driver is a great update! Waiting for finish and numbers
I've been disappointed with the QC as well coming from them, but I'm lik'n the chunky design more and more. Mass and surface area are the two big issues with high amps, so they got the mass part down pat, as long as I can fix up the other stuff . I have 2 other Haikelite on order, the TK35 and SC01, and planning on getting the MT07S.
What I like bout what I'm seeing is easy modding - nice driver retaining rings, standard size drivers in width and thickness, easy modding for the LED's and battery setups, etc.
Made some SST40 led testing so I ended up with a Convoy C8 with TA17 driver, SST40 N4 BA dedomed led, AR coated glass lens, bypassed springs, 8,6A current in turbo, 2000 lumens, 136 Kcd and 738m throw In a C8 it is insane!
I got 3 of those on the way from KD. Those are pretty nice #'s, specially the lumens for a dedomed LED that throws almost as good as the best dedomed XP-G2's, I think. Didn't know you can get that many amps out of one. Might just put them in a SRK. What do you think of the tint after dedoming, and the beam pattern?
Hhmm, for that price, might order a bunch more.
Ohhh - and these are "only" N4 bins. There's 2 higher bins listed in the specs, but who knows if they will ever happen (N5 and P2).
Upside down on some wires in regular 95 octane petrol. It took 3-4 hours and a bit of picking with a needle and falled down. After that cleaning with alcohol rinse and a needle under magnifying glass.
First attempt at XHP Soup, HOT fluid de-doming (tried 2 different fluids, the second fluid performed better) XHP35ās 50ās and 70ās all meat no veggies!
Brand New $8.00 Garage Sale Crock pot, so far soooooo gooooood!
I made sort of a cooperative multitasking toolkit with event callbacks and a finite state machine, to make it easier to create e-switch light UIs.
It works on tiny45 and tiny85, and it should be reasonably easy to add support for other MCUs later. Most of the hardware details are abstracted out to allow interfaces to be portable across different types of drivers.
In a C8 it is insane!
