I made this mod last week, and have been waiting for my site to come back online, but its not happening.

So, Logic is kind enough to let me borrow some space to host it. /ubbthreads/images/graemlins/smile.gif

I wont post all the pics and such in the thread, cuz later they will all have to be changed whenever I host it, so, for now, just view the webpage I made for it.

----------------------------------------------------------------------------------------------

The MagUflex is a 2D Maglite, that has been modified with a "Uflex" Circuit and TWAK LuxIII LED.
This project started a LONG time ago, and has been changed, and revamped more times than I can count. Becuase of this, the lights fit and finish is not near what I would like it to be. Half way through this project, I knew this one would end up being a good learning experience. This light turned out really well, and is super useful.

First the Mags switch had to be completely gutted, and room made for the Uflex to fit inside it.
Then the momentary push button was wired to the Uflex, and the two were then AA epoxied into place. Alittle hot glue here and there for good measure.

Then wire was wrapped around the groove on the bottom of the switch assembly.
This is something I will do very differently next time. Next time I will make the negative contact via the retainer ring that holds the switch in place. That way the batteries hold it tight at all times.
This first version just makes contact by the wire that is pressing up against the inner wall of the maglight. Which has had the anodizing removed in order to make contact. It works, but I think the other way would have been alot better.

The "Pill Sink" is a special heatsink that me and Roth worked on. I basically came up with the idea, but couldnt make it at the time, because I didnt have my lathe yet. Well, we changed plans so many times, it caused the sink, and the rest of the light for that matter, to become something totally different from what I set out to build.
That is why the "Pill of the sink is alitte messed up now, it had to be modified alot. The screw that holds the pill in place, was sticking up, and interfering with the reflector, it that had to be taken care of.

This "Pill Sink" design allows yout to change the LED without actually popping it unglued from the sink. Each LED is epoxied to its own Pill, with its very own wire harness. When you want to change LEDs, you simply take out the screw, pop out the pill, and pop in the one you one that particular day.
The connection to the Uflex is made by a computer Hard Drive LED indicator light wire harness. Fitting isnt it? /ubbthreads/images/graemlins/smile.gif This allows you to even pop out the entire heat sink, and not worry about it jerking loose, and ripping wires out of the Uflex. It will simply pop right off.

The Uflex itself really makes this light AWESOME !!!!!!
This model is set to 1000mA at the highest level.
It has 8 brightness levels, that can be stepped trough by simply holding down the button.
You tap the button to turn the light on and off.
One really nice feature, is it will remember what your last brightness level was when you go to turn it back on. BUT, if you press and hold the button to turn it on, it will automatically goto its dimmest setting. This is really useful for times when you come in from outside, where you were using the light at full power,,, but in the house, you dont want it to turn back on in full power, and blind you.

The Uflex also has a auto dimming feature. I am not even sure how that works yet. But i think you can set it to set down in brightness over time, to save batts. Plus it makes sense,,, as your eyes are adjusting to the light.

The light is powered by 8 AA batteries. That are help by a custom holder I made from a Radio Shack battery holder. Its a VERY tight fit, and most the holders body had to be cut away.
This light could also be ran off of 2 or 3 123 batteries.

Light output on high is very nice. The mags reflector makes a very tight spot, which makes this light a great thrower. The lights focus is also still adjustable just like the stock Maglite.

Here are a few pics of the light being made.
Please excuse some of the mess, these were taken before the lights final assemply and cleaning.

Thanks to George80 for his AWSOME Uflex circuit !!! /ubbthreads/images/graemlins/thumbsup.gif

Re: >>> The MagUflex <<<

Amazing!
I am working on something along those lines myself. Have the two 4 AA to D adapters and a Maglight to start off. Need to get the Hotlips, Uflex and (I hope) a X3T 5 watter. Thanks for letting us know how it all works together, the action is intuitive. Press and hold for low light at night and press and hold to scroll through the brightness settings. Love the memory feature to keep the operation simple.
Need to get off my butt and order some parts, I will be gone for 5 weeks to Cleveland playing around with CT scanners. Nothing like Cleveland in Feb/Mar /ubbthreads/images/graemlins/jpshakehead.gif

This is way cool. /ubbthreads/images/graemlins/grin.gif
 
Re: >>> The MagUflex <<<

jtice,
very nice! Same thing I will try in te near future. Now I am just thinking and was stucked at the how to make room in the pushbutton mechanism.
Did you replace the whole pushbutton or using the original one (and aware that should not push it entirely?)
 
Re: >>> The MagUflex <<<

Thanks guys, I REALLY like this light.
Its soooo useful. Its great to be able to pick a level of light suitable for whatever situation you are in .

Printer,
I had to completely remove the stock switch. The ONLY thing left is the big plastic part that held the switch and bulb base assembly.
It now has a momentary push button. Much like the one supplied with the Uflex, but slightly larger, and with more travel.

Only bad thing is, my friends tend to pick it up, and try to push till it clicks.
 
Re: >>> The MagUflex <<<

Very nice Ticey! VO is the wave of the future.

I love the concept of modularity. Being able to easily switch Luxeons is brilliant. In fact, this whole mod is brilliant from top to bottom.

Ideally, you could have a few Luxeon modules, with mix-and-match resistors, or regulators, and several battery tubes and bezels that you can insert them into. Your mod is helping to lead the way to a better flashlight world.

Luxeons should be just as easy to deal with as PR bulbs.
 
Re: - The MagUflex -- Variable Output, Variable

Thanks for the kind words guys.

The 8AA battery holder could run 6 or 7 AAs also, I think the Uflex would run just fine off that.

I can also stick 2 or 3x123 in it. Runs just as well, and is alot lighter.

I currently just have the White LuxIII TWAK, and the 5W Cyan LED Modules for it.

The converter doesnt need to be changed with the differnt configurations, that the beauty of the Uflex, it will run up to 1000mA, and up to,, I think 20 V.

And as far as heads, a 3" Carley turbo head is next. /ubbthreads/images/graemlins/wink.gif
Just havent got my hands on one yet. /ubbthreads/images/graemlins/frown.gif
 
Re: - The MagUflex -- Variable Output, Variable

Nice! What I like the most is the modules. I had an idea about that long ago, but alas no means to make anything like that. Simple as changing bulbs! Dimability is nice as well, but seems to be most usefull in broader beam apps, such as 5w. No one can really use a tiny spot with no sidespill at dim levels close up! I guess you can unfocus, but then theres that black hole!
 
Re: - The MagUflex -- Variable Output, Variable

Good man, you are ahead of me. I didn't do it because I was worry about the length may be too long even if I chop off the oedestal of the switch assembly.

Now, you proved that by chopping a bit further the thing can be done. Good job, I will go for it. Thanks for sharing.

jtice -

The "auto sleep" of the uFlex actually effectively turns the light off for you, if you leave it on for longer than 45 minutes. You set it up for this feature by pressing and holding the button until it comes on dim then bright, then dim again. Release the button at this point, and it is in auto-sleep mode. After 45 minutes, it will automatically drop one level per minute until it reaches full low. It'll stay there for another two hours, then enter sleep, or OFF mode. The idea behind the stepping down is so it didn't just shut off and leave you in the dark if you really wanted to leave it on that long. A good safety measure to have the auto sleep turned on.

Great mod, BTW! /ubbthreads/images/graemlins/thumbsup.gif
