FS: Coleman MAX CR2 Kits

Mohrenberg · Apr 14, 2011

Right now there are 2 "scratched" kits left. everything else is sold.
I'm keeping one for myself

Now i just need to get a jib driver.

steviedezie · Apr 15, 2011

are you gonna run these with a 445 at 1.3A with cr2's??? isnt that pushing the batteries a bit much?

rhd · Apr 15, 2011

You can get as much as 1.5A from 2x CR2s in my experience.

Mohrenberg · Apr 15, 2011

and it should be perfectly fine with AW brand batteries.

Mohrenberg · Apr 18, 2011

I still have two of the "scratched" versions left.

steviedezie · Apr 18, 2011

Hey guys I'll tell you these scrathed hosts dont even look bad in person. I got 1 of them, its hardly noticable. Still looks great to me and at this price its a frickin steal. Jump of these guys!!!

hey Mo, how deep are the scratches.?

Edit: Dint see Post above.^

rhd · Apr 26, 2011

Silly question - how do you grab the battery (-) feed in these? The head threads are anodized, and the heatsink isn't picking up the case charge as a result.

Mohrenberg · Apr 26, 2011

the top of the host body pinches down againt the heatsink when you screw it down. If you scratch off the top poart of the body so that it's a metal contact when it's screwed down against the heatsink you'll get a connection no problem.

Got it (different approach, but it worked)

I just built one of these with a 1.66 A (at least that's what it's wired for) 1085 diy driver. Awesome build. Love it

EDIT: Holy smokes Moh, I got this host to do over 1.5W

I love this guy! Here's the driver approach I took:

Thermal pad, with IC thermal epoxied in place:

4x Parallel SMD 3 ohm resistors (easiest way to get 3W + in a small package)

And a ton of epoxy at the end, to keep everything in place.

Because of space issues, the protective cap needs to be moved to the diode itself. This is a solder job that requires very quick soldering, and very quick cooling (I like to toss a wet piece of fabric on the diode leads the second I've soldered each side of the cap, so that the bulk volume of solder doesn't retain heat any longer than necessary)

The final product - GETS HOT FAST!

LPMs at over 1,500 mW raw optical output.

i thought the pill also has a negative connection point...but i guess you opted to not use the pill...

either way great stuff.

P.S. where did you get the thermal pads from. Beats the heck out of using artic silver for everything everytime, and wasting most of it. i always end up using 1/4th of what gets squeezed out.

rhd · Apr 27, 2011

Actually, there's no pill on these at all.

Scratch that - there is, in a separate bag. I've sort of ignored them. Probably should take another look.

steviedezie · Apr 27, 2011

ohhh...thats right, i requested Matt to include the pill, the led, and the batteries that came with the host. I figured i was gonna need it so yea...helps with the negative connection so i dont have to mod nothing.

rhd · Apr 27, 2011

No, it's not Moh's fault - he included them for me too, I just ignored them foolishly - though I like my result

I've never had 1.5W in such a small host.

hey were these those 110 Lumen flashlights.
If they are how much you want for just the LED.

Mohrenberg · Apr 27, 2011

I didn't keep the LED's. They were included with each of the kits.
That's a sweet build RHD. I'll take the getting hot fast as a good sign that the heat is being transferred to the surface for dissipation.
