Title: FiveMega Custom 1D Light
Post by: Lips on December 25, 2006, 11:24:01 AM


FiveMega Custom 1D Light   

HA III  Gun Metal Grey with finned head and very grippy  grip.    :thumbup:



Nice and bright with an Axial 4 volt bulb running 4 Nimh in a FM custom battery pack with charging jack in rear tailcap.  Bulb is custom made costing $18 each. I fried my one and only turning the light on fresh off a chargeÖ   :'(     Good host as Lux said, hot-driver running WA-1166 bulb with 4 Lith Ion in series, very very bright but short run-time...  8)



Also would make a nice LED mod light.

And he just did another run, this time with battery holder for 2 sets of parallel 2x14670 lithium ion batteries (4 total used) for 7.4 volt, which he is saying drives the WA-1111 at over 900L.  I am not familiar with that bulb.  His sale on these sold out in 12 hours though.  These are really sweet.

I lucked out with one of these as well.  Can't wait to try it out.  It's a match for a 1.5 and 2D in the gunmetal gray--real nice finish and color.

Did your color of the new 1D match your previous gun-metal-gray lights.

My new one was on the purplish side...

I'm such a danged slow poke in my payment "system"--US snail mail (no PayPal) that I haven't gotten it yet unfortunately.  I just PMed FM and he hadn't even gotten my letter (and payment) yet so, I'm sure I won't have it until next week.  I do have an extra bezel that is the gunmetal gray HA which is a bit lighter and, on the purplish side as you have said.  I'm going to believe that the 1D I do get, being from the same batch as yours, will be lighter as well.  I'll let you know when it comes though.

As I posted on "that other forum" this little baby is very damn close to my best 1185, and 1D Mag66 (4x14500 series w/ AWR Hotdriver).  I really cannot tell a difference in brightness from the 1185 with throw and white walls.  You are very lucky if you got one of these 1111's promoted as 900L...even if a shade of purple different HA-III.

I ordered an extra battery pack of 4 X 14670 for the 1st 1D light that's pictured in first post. That light uses 4 x AA.

The tailcap will have to be shaved a little but should give more runtime and the ability to run WA 1111 bulb with that package. $6 bulb vs $18 bulb with more light...

Almost Mag85 output in a 1D package,   awesome...   :blinking:

I have to tell you guys...


I did a tailcap spring Mod and a PR front spring Mod on this light the other day using solder wick to cut down resistance. No blown bulb even after firing up after full charge...


This light combined with a cammed FM MOP reflector is a M6 Killer. Extremely bright, light weight, adjustable beam, easily recharged with plug in tailcap, 900 bulb lumens in an incrediably small package.

Lithium Ion means it will sit up without discharge and be ready to go at a moments notice.


Incredible power in a small package, get this light next time it comes up! You want regret it...      :blinking:

The tail cap spring is just soldering a thick wire from back to front, like this right? 

(http://i61.photobucket.com/albums/h75/pike444/spring1.jpg) (http://i61.photobucket.com/albums/h75/pike444/spring2.jpg)

But then how did you do the "PR front spring mod"  and are you still using this with the 1111 bulb?

Nice looking tail-cap spring Mod Lux. I saw one of AWRís spring Mods using Desoldering Braid ( 64-2090 B ) and have moved to using that instead of regular wire. The Desoldering Braid is flat which makes it very easy to work with although itís not as sturdy. The solder jumps to it and it is easy to get it out of the way of the battery packs charging jack that needs to go in the center of allot of the spings.

The PR front spring Mod is easy to do with the Desoldering Braid. You can tuck the flat Braid in-between the spring leefs and solder so it stays in place better. Take the caps off the PR bulb holder and put a piece of Braid from end to end of the spring, solder and then place the silver caps back on. A little progold everywhere too.

Iím using the wa-1111 bulb in this light now with the 4 x 14670  2p2s holders. This configuration is working nicely in both my 1D lights with both spring mods done without insta-flashing hot of the charger.   

Iíll take it apart Sunday and post some picks of the PR spring MOD.

Oh so you meant the small center spring inside the plunger below the bulb holder socket, that looks like the spring from a ball point pen?  I was thinking you meant a wire going down to (+) battery contact spring...which I"m not really sure how to rig that up, or if you did both that are shown there.  Did you use that "solder wick" wire?  Where do you get that?
Title: Re: FiveMega Custom 1D Light
Post by: andrewwynn on March 15, 2007, 08:19:01 PM
i absolutely love this little light.. the new models that can hold 14650s are a total gimmie for the 1166 i call the "M66" like luxluthor mentioned... it's a fully regulated 600 torch lumens.. on par with a fresh bat pack M6 and about identical in size..

http://M66.rouse.com for the thread and http://rouse.com/M66 for beamshots..

nice job on a 900L 14.4V lamp.. if you ever get tired of blowing $18 lamps get a hotdriver it's a drop-in solution that soft-starts and gets more voltage to the lamp.. (15-20 miliohm resistance.. 1/2 of a kiu socket solution).

When using a PR adapter as most FM mods come.. and not fixing the tailcap spring.. the circuit resistance is about 0.215... fixing the PR with the wires as shown in the referenced photo album will drop 5/6ths of the resistance of the switch mechanism.. from about .18 ohm to about .03 ohm.. and the tailcap spring fix as shown above and also here (http://homepage.mac.com/rouses/circuits/PhotoAlbum373.html).. will drop about 97% of the spring's resistance..

be warned.. many hotwire lamps can not take too low of resistance solutions.. when i blew 3x 1185 lamps in 3 days was when i lit a fire under my butt and got the hotdriver prototype operational in about a week (been on the drawing board for months).

For those with this particular lamp.. the 'M66' is really the gimmie solution.. lamps for $5-6 that last a good while and are spectacularly white and bright.. with NO dimming.. fully regulated 'til the end.. a Lion battery is good down to about 3.45V under load.. that is 13.8V and i run the 1166 at 12.55V (for 600 torch lumen).. it's a stunner!

just caught you are using 2S2P battery and 1111.. you can expect about 532 nominal lumen.. it's quite a nice and about the best direct drive solution.. higher voltage and lower current is a key to knocking out resistance issues, probably a big part of why the 1166 can get more output out of the same cells if configured 4S1P. (with regulation of course).

Yeah that Mag66 1D light that AWR fixed up for me is by far, my favorite go to light...the only thing that makes me nervous is all the reading I just finished doing about the dangers charging unprotected Li-Ion's which it is using.  Scare the crap out of you videos of the fires with these cells in my post here (http://www.candlepowerforums.com/vb/showthread.php?t=152013).

Now I'm also gonna use another 1D with this 43W Carley light used in this light (http://www.candlepowerforums.com/vb/showthread.php?t=147729&page=1&pp=30).  This light is incredible.

Post by: andrewwynn on March 16, 2007, 09:19:28 PM
don't worry so much lux... it's far more difficult to cause a real problem than you might think.. the really scary stuff happens when you use LIPO not LION and if you charge to too high of a cell count and at too high of a rate.. i have personally destroyed two packs of 17670s by mangling the charging connection or by trying to charge over-discharged cells.

1) impossible to over-discharge if using hotdriver.. the M66 will shut off at 2.9V/cell.. so as long as you monitor once in a while (say every 3 months) that the cells are reasonably close to the same voltage you won't over discharge to be able to badly charge.

2) pay attention when charging, and i believe you have a 4-cell 500mA charger.. you can not pick '5 cell' so you can't really instruct the charger to badly charge them... you should monitor the voltage  before charging... it should be really close to 10.8V 'dead'.. if it's 9 something.. investigate before charging as one of the cells or more is damaged.

3) check into the aw 14500/670s (i forget if you have the ludicrous short 1D or the really 1.5D second gen of that light).. they are a little longer so futzing would be needed i  believe to get everything to fit in the light... unless you already have the aw prot. cells (black not blue).. i can't remember..

4) the carely lamp could be used with the LIONs.. and far more safely for the lamp if used with the hotdriver.. it would be very easy to dial up the volage on the hotdriver you have to be 14V for example. (no point in setting to 14.4.. those cells will not hold voltage that high with that high of current!).

Andrew, I am not as worried now that I have learned about the hazards, balancing, protected vs. unprotected, etc.  I have enough safeguards in place now, that even if there was a lithium cell fire/explosion, it's not going to be in a place that could cause any serious problem (garage concrete floor, or fireplace, or outside).  We discussed this in more detail on the CPF topics though...so no need to repeat it all here too.  I was never that worred about over-discharging the cells...rather over charging out of balance unprotected cells...like the 14500's you put in the Mag66 for me.

I have most of FM's Maglites, including this shorty 1D (http://www.candlepowerforums.com/vb/showthread.php?t=146499&page=1&pp=30), this recent 1D that you made into the Mag66 (http://www.candlepowerforums.com/vb/showthread.php?t=132019&page=1&pp=30), six of those 1.5D 700L 1331 (http://www.candlepowerforums.com/vb/showthread.php?t=132697), this 1.5D (http://www.candlepowerforums.com/vb/showthread.php?t=149017&page=1&pp=30), & some others that I have bookmarked.

I'm trying to find out how to setup a safe way to charge 4 or 6 Lithium cells in series & using balancing with my Hyperion 1210i & LBA10 balancer module.  So far no luck on how to do the wiring like they have it in RC Lipo battery packs.

don't worry so much lux... it's far more difficult to cause a real problem than you might think.. the really scary stuff happens when you use LIPO not LION and if you charge to too high of a cell count and at too high of a rate.. i have personally destroyed two packs of 17670s by mangling the charging connection or by trying to charge over-discharged cells.

Tail cap with Soldier Braid


Best to leave unsoldered in the middle because the braid snaps easy on compression if soldered. The braid wraps easily around the sping and I like to use a double strand. Flexes nicely...

I'm gonna start a Resistance Mod thread and Bulb Centering Thread. Need your photos for that  ;)
Title: Re: FiveMega Custom 1D Light
Post by: andrewwynn on March 21, 2007, 04:40:32 AM
after doing half a dozen or so of these mods.. i can say without a doubt the stranded wire method works better.. i've measured 7-10mohm resistance on the likes of the solder-wick solution and as mentioned above.. it's really easy to make solder wick not-flexible in fact.. it's quite difficult NOT to do it. It is however much better than nothing :-D.. the 1-curl of 16ga wire (i use scraps from KIU upgrades).. works wonders.. drops the resistance to <2mohm!

Post by: Lips on March 21, 2007, 04:48:12 AM
I had trouble using the 16 ga wire with battery holders that have the charging jack through the center. Hard to solder and hard to get out of the way...

Andrew did you double the Braid when you measured. May have less resistance than 1 strand...
Title: Re: FiveMega Custom 1D Light
Post by: LuxLuthor on March 21, 2007, 10:33:55 AM
I still cannot figure out how that top spring mod is done...in terms of what is soldered from AWR's images.
Title: Re: FiveMega Custom 1D Light
Post by: andrewwynn on March 22, 2007, 04:51:46 AM
are you talking about this mod (http://homepage.mac.com/rouses/circuits/PhotoAlbum289.html)?

and in particular
(http://homepage.mac.com/rouses/.Pictures/Photo%20Album%20Pictures/2005-11-24%2014.59.27%20-0800/Image-CC3BDFBE5D3C11DA.jpg)

This picture?

It actually is an earlier version of the mod.. where i still utilized the cups at the top n bottom of the spring..

anyhow there are a couple ways to do this mod:

1) exactly as shown here... where a coil of very flexible copper wire is spiraled the opposite direction from the spring (very important so it doesn't stick out and cause a direct short on a grounded part).. and it soldered to the top and  bottom cup.. look at the 'mod link' above and go step by step and read the captions..

2) solder a very flexible wire to ONLY the top cup of the spring.. feed the wire down through the spring and out the base of the PR as shown in this pic:

(http://homepage.mac.com/rouses/.Pictures/Photo%20Album%20Pictures/2005-11-24%2014.59.27%20-0800/Image-CC3D67DD5D3C11DA.jpg)

Than that wire (black and white in the picture) gets fed through the hole next to the ground strap and is soldered directly to the top of the switch contact itself.. shown in this picture:

(http://homepage.mac.com/rouses/.cv/rouses/Sites/.Pictures/Photo%20Album%20Pictures/2005-11-24%2014.59.27%20-0800/Image-CC3CE42B5D3C11DA.jpg-thumb_269_202.jpg)

with this add'l information.. go double-check the prfix and see if you undersatand now.

oops missed Lips' questions..

1) i used one braid but it was thick.. probably only 24ga or so though.. flat wire is not super heavy-duty.. double strands will half the resistance.. i wouldn't re-do a double-stranded fix like you describe.. even just 1 strand is enough to make it worth it.. but if 1 strand is 9mohm 2 will be 4.5.. with 16ga wire it is 1.3 mohm.. and it's easire to do the mod as well.. definitely a win-win.. i did my first mod with solder wick.. i now only use 16ga KIU kit leftovers ( i have them coming out of my ears ).. and they are the perfect solution..

you can avoid the bat-pack problem by soldering below the top spiral.. once the wires are all touching each other.. the effective resistance drops to nil... e.g. if soldered like this:

(http://homepage.mac.com/rouses/.Pictures/Photo%20Album%20Pictures/2006-09-13%2022.30.02%20-0700/Image-A0F938A843B111DB.jpg)
(new style spring)..

You could solder below the 4th loop in the spring vs on the top to get 100% clearance and probably not make the resistance go over 2mohm.. a negligible difference in the resistance due to the massive parallel wires.. it wouldn't hurt to put some pro-gold between each spring leaf or even just solder them.. make sure you sand the crap out of what you want to solder.

oh.. just for funn... check out this abused tailcap spring and see what 35mohm of resistance does when the maximum current is pushed through it.. it must have gotten cherry hot to deform it:

(http://homepage.mac.com/rouses/.Pictures/Photo%20Album%20Pictures/2006-03-26%2017.11.00%20-0800/Image-37678178BD2E11DA.jpg)

oh and yeah.. the battery cells weren't all too happy about that either.. as you can see.. moral of that story.. don't dead-short a 12xCBP pack.

Post by: Lips on March 22, 2007, 05:23:09 AM
Lux that's what I was talking about in Andrews first pic.  I did mine just like that...



Ok, I like the newer method of bypassing the bottom cup. Thanks for that tip  :D


On the battery and spring -  I'm talking about the holders that have the charging jack going through the center of the spring. Not talking about where the holder hits the spring. A pack with this type of charging jack is not going through that spring with the 16gauge wire you have shown. It wouldn't make it... Some of the FM holders are fat and some are skinny at the charging end. On the fat ones you have very little room on the inside of the spring...


Cheers

Post by: LuxLuthor on March 24, 2007, 05:25:50 AM
AWR & Lips, yeah, I always understood the #1 wire inside of the top spring soldered to inside of top and bottom spring holder caps.

I'm still not quite following the 2nd one because you can't see what it is soldered to in the spring/caps from #1...then I'm not sure how if the wire is soldered to the inside of the top cap, is it threaded down through the spring, and just pulled out between the spring coils before reaching the bottom cap? (This picture I can't figure out where wire is coming from inside the slot (http://homepage.mac.com/rouses/.Pictures/Photo%20Album%20Pictures/2005-11-24%2014.59.27%20-0800/Image-CC3C364A5D3C11DA.jpg)) 

I  don't understand what this loop is doing or where it goes (http://homepage.mac.com/rouses/.Pictures/Photo%20Album%20Pictures/2005-11-24%2014.59.27%20-0800/Image-CC3D0FA65D3C11DA.jpg).  If that same loop is now down through a small hole in the plastic and soldered to the top contact (http://homepage.mac.com/rouses/.Pictures/Photo%20Album%20Pictures/2005-11-24%2014.59.27%20-0800/Image-CC3C5FB35D3C11DA.jpg), I'm not seeing the loop.

Now you see the black and other wires (http://homepage.mac.com/rouses/.Pictures/Photo%20Album%20Pictures/2005-11-24%2014.59.27%20-0800/Image-CC3D39B55D3C11DA.jpg), which I saw from previous images soldered to removed blue switch contacts, but I'm not sure where they are going in this image because you can't see inside the slot (http://homepage.mac.com/rouses/.Pictures/Photo%20Album%20Pictures/2005-11-24%2014.59.27%20-0800/Image-CC3D67DD5D3C11DA.jpg).

I can't tell what is soldered to what in this image, and what is going on with the bare wire inside the switch (http://homepage.mac.com/rouses/.Pictures/Photo%20Album%20Pictures/2005-11-24%2014.59.27%20-0800/Image-CC3D8F985D3C11DA.jpg).  I can also see that there is a wire coming down into the bottom of the whole switch assembly, and soldered to the (+) battery contact spring.  I don't see where that wire is coming from...and which is not shown in your pictures.
Title: Re: FiveMega Custom 1D Light
Post by: andrewwynn on March 24, 2007, 06:39:53 AM
the spring-cups solution was the 'older version'... in a newer solution i will solder a very flexible wire up through the spring but on the bottom solder it to the black/white wire..

The first hyperlink goes to the picture of the ground wire.. that mystery loop is attached underneath the roller wheel which comes off with the same tool you remove the switch from the light (5/64 or 2mm hex).

All of the 'round bare wire' stuff is the negative which goes from the little loop on the wheel to the ground strap.. the black and white wire goes from the top of the switch (contact on blue plastic).. around to the bottom of the spring.. soldered inside to the solderwick type wire through the spring (but at the bottom to allow for motion).

In the last image where you can't see what is going on.. ignore any of the 'tiny wires' they were just for measuring the resistances after the fix... the bare wire is soldered to the ring that is attached to the nut (which has been cut to make room for the black n white wire.. the black n white wire is soldered to the top of the blue plastic switch.. to the top contact.

Below the blue plastic in the hole below the nut is another piece of wire and breaking with tradition it is bare not covered, but that is a directly wired piece of 16ga copper wire that goes from the bottom switch contact to the battery spring on the other side (through a hole drilled for such a purpose).. the contact is made on the tip of the spring not the base.. to eliminate the spring resistance there as well.. sorry i missed the description of that part i think.

ps.. important followup:

regarding this picture... the loop (made from 24ga wire) must be continued into an ? shape around the circle and back onto itself for strength.. the original design here will not hold up to enough cycles through focus range. The loop would go up from the fat wire, around in the circle which fits under the roller (you will figure out if you take it apart where it can fit tight and w/o binding the roller).. than comes back down parallel and back to the fat wire... soldering the whole length.

That whole part is brass.. you can actually clean off some chrome with a dremel wheel and with enough heat solder to it from what i've heard.. but this is clean and elegant... make sure that there is clearance and nothing catches or binds through the full range of motion.. including the reflector stem that it doesn't catch!

I'm still not exactly sure what is going on every step, but it seems like too much work for the benefit.  I might do that single wire inside the top spring from bottom to top cap...but thanks for the additional details.

Here are some pictures I took comparing the 3" heads on various lights (http://www.candlepowerforums.com/vb/showpost.php?p=1935053&postcount=265).

Nice pics of all your FM heads!

the single wire through the middle will drop the resistance to less than half the initial (80mohm from 160-180).. adding the external wires drops it to about 35-40mohm.. less than half again.

This turned out pretty good so decided to share...

I gotta get a digital camera that has TTL bounce flash capabilities...

What is unique about those three lights?  I'm not sure what I should be noticing.

They are special since I don't own any of them!  So many lights ! 

Nice pic Lips - perhaps as a quick fix for the flash is to get an inexpensive slave flash to orient as required, and then put a piece of 35mm film over the exisiting flash.  Enough light well escape to trigger the slave and should achieve good results.

Oh yeah well from just the photography aspect, it is great...and the lights themselves are great..but I was thinking he was trying to point out some feature of those 3.  OK nevermind then.

I was fortunate to get in on FiveMega's last offer of a D sized custom running 6 RCR123 at 7.4V. I put a FM cammed reflector, borofloat lense, gold ceramic bi-pin and a WA1111 bulb. To my eye, looks very close to my Mag85. A bit less perhaps, but hardly noticable. A very nice carry size for evening walks. Fits perfectly in my barn coat pocket.

LOL...that's just my HA gray variations...and when I count again today, I have 12 gray ones.
