Re: Any interest in an 2x 18650 EDC ?? Pictures Included
I am taking note of these ideas and will put most of them to practical use with this project.
Cause i Loves me Some Challenges!
#2 The whole point of my design was Versatility.
I wanted to give people the ability to have multiple led options when in the field, on the road, underwater.
It is basically a light that won't go out of style anytime soon, Becuase of the options i will make for it
#3 The heat will transfer from the led to the body of each removable led module, and then to the body of the light with a replaceable thermal transfer pad. I will have more drawings up soon to show you how its done.
#4 The Quad-Die Led's are being worked into the plan. But they will not be run at their full drive currents for sake of heat dissapation. Yes, i know that sounds silly, But those particular led's will be used for a Flood beam, and be driven at 1400mA to be on the safe side of heat dissapation. Even if you run a quad-die led at that level, you are still outshining any single die led out there
#5-9 Maybee we should talk further about this driver design.. P.M. me with you driver ideas if you would please. You do seem to have some good ideas here.
And thats why i asked people for advice on the project.
It will be a community project
Hmmm, maybee that could be arrainged!:tinfoil::tinfoil:
I wanted something that can take the very common 18650's.. and with a spacer tube, your 18500's
That is a Wonderful idea! My Machinist buddy can make custom plastic-injection molds that can be made to have the magnets cast inside the rubber booty from protection. As far as a stand, thats an easy one too
I am taking note of these ideas and will put most of them to practical use with this project.
#1 I have allready thought of making a Single-Cell 18650 light that will use the same interchangable heads as the "Chimera". It would be a little easier to make too, but thats not the point#1 Even though I like your double li-ion, double LED flashlight concept (I thought up ideas to use two 18650 cells as well, but didnt go anywhere with them), it would be neat if you could eventually create a single 18650 cell, single LED flashlight.
#2 I like the idea that you can slide on different heads for different uses.
#3 I hope that the LED modules will be able to heatsink the LED adequately.
#4 The MC-E and P7 creates quite a bit of heat when powered at spec currents. I hope you can find nice optics for each LED, as well. I know you will not be able to create a "thrower", but a wide beam of light is more useful most of the time.
#5 Can I suggest that you put an LED driver into each module, then use the circuit in the flashlight body strictly for battery monitoring and switching and/or mode changes?
#6 You may find it difficult to design an all-in-one LED driver that can power a single XR-E at ~3.5V and 1000mA, a MC-E in series (~3.2V X 4) at 700mA, a Seoul P7 at 3.7V and 2.8A, and a colored LED at its ideal voltage and current (Red Luxeon III at <3V at 1500mA).
#7 Plus, for a driver circuit that is in boost mode to drive something like the MC-E, it is bad if someone forgot to pop in a module head, then they switched on the driver (it may be a tough as nails light, but it has to be user-proof as well).
#8 For many boost drivers, it can destroy themselves if you remove the load and put an open circuit on the output. However, if the boost circuit is like the Shark or TaskLEDs Chippo (can have an open circuit on the output), you will fry the LED if you insert the module after you turn on the driver (the driver will be operating at its max boost voltage at the time).
#9 If you use individual drivers for each module, it will make things much less complicated in the design. You will see that many LED drivers are designed to be around 0.55in (14mm) in diameter to fit in common sized flashlights. You can use individual drivers for each LED type for specific voltage and current regulation needs, then use an universal driver in the body that uses high frequency PWM switching to create your modes.

This sounds like a truly amazing and versatile light. Depending on cost I would probably be in for one. I am definitely subscribing to this thread.
Great ideas and I hope this comes through at a reasonable cost. Keep up the good work.

I understand that totaly....
I was looking for a more compact size while not being to small either....
Thanks...!
This one is sure intersting....!

Any estimates on price?
$50-$100? (I wish know it won't happen)
$100-$300
$300+?
I hope for the sake of my wallet that these are nowhere near as expensive as the Spy 007's.

A single head side by side 18650 light would be nice.
Is it possible to do this and use P60 sized drop-ins?
There is something exciting :naughty: on the way in the p60 sized drop-in market and a body like this would be just the right showcase for it!

Re: Any interest in an 2x 18650 EDC ?? Pictures Included
I would imagine that one larger head could be used, mounted with both mounts, but driven through only one... or a MC-E in 2S2P driven through both!

My "Roundabout" price is 500$ but that can change
because i am still in the design stages. The light will
start out in Aluminum, and later on, Titanium, and
other exotic metals will be put on the list. But aluminum
is the starting point to get this design out the door and
in peoples hands
Prototyping will be in a Bismuth/Tin Alloy from a reverse
wax casting method. That way i can play with it at home
instead of sending it off to the machinist at every design
change. I can't link it directly, but the metal is called
"Cerrocast" and is composed of 40%Bismuth/60@Tin.
It is sold at Mcmaster.com, Go to Metals at the bottom
of the page in "Raw Materials".
And it has a melting point starting around 281F.
I just need to hand "Machine" :naughty: the wax to my desired
shape, cast that in plaster, and then heat the plaster
to release the wax.. Then pour the metal, and Viola!
Instant Edc!! This won't be a final product, but one
i can pass around for Cpf Members to play with.
Who wants to be on the list of passarounds?? Beuller?
I was thinking of that, but i need a sample of the dropin
to use in my design. I am going to make the "Pill"
design more universal than i had originally planned.
So that gives people more options for upgrades and
makes it easier to find parts. The 18650's will be setup
Independantly, Ie, they won't be in series or parallel.
You can option for 2 different switches, Reverse, or
Forward Clickie. For instance, The left side will be a
Forward clickie for tactical use, and the Right side will
be a Reverse Clickie for changing modes easier if the
pill you have installed has different mode to change.
I will initially be using a Reverse and Forward clickie in
"Passaround Prototype" along with a 15-Mode
customizable driver, powering a Q2 led in each head.
The driver is a Buck/Boost capable of running from
1v-4.5v. That means you can use a single AA/AAA
in an adapter tube (That will be included) or
14500-18650's with the appropriate adapter tube.
Does all this sound good ?
Let me know what else you can think of..

I'm not quite getting how the batteries are going to work. Not series and not parallel. Is each battery going to power its own head? If so, what if you run one cell out but want to continue using that head?

Re: Any interest in an 2x 18650 EDC ?? Pictures Included
You "Could" actually run both cells in parallel...
But, you would "Have" to change both cells at once
when they get low. If you mismatched a dead and
charged lion,
It would be easy to put a switch
inside the light to make the batteries work in
parallel or independant modes. If you wanted to
run an 18650 and a CR123/RCR123, then put the
switch to independant mode. The same would apply
if you wanted to run an AA and an 18650.
Then, if you wanted more runtime on single head,
just switch it to parallel mode. Same goes for
running 2 seperate AA's or even AAA's.
I can put pushbutton switch on the outside
of the light, or right behind the battery door.
It just depends on how safe you guys think it is
by having the switch outside or inside. Think if
you accidentally switched and AA and an 18650
in parallel !! :tinfoil::tinfoil: goes your pocket!
More Good Suggestions Please :candle: :kiss:

I just had a brainfart about how to make the light
hold AA, AAA, 17650, 123's, and 14500 batteries
"without" an adapter or spacer tube.. It will also
be included in the light design..

Im just thinking about my favorite Setup.:thinking:
1.Head:Allround-light,Heavy Orange-peel Reflector (or an Optic) for smooth Flood & Mid-range lightning.Brightnes selectable by Driver maybe.
2.Head:Mini Aspheric Thrower:devil:
Hmmm...that woud be my Baybe....
I know, i know its too earliy for this...
(But seriously interested)

Do you know how many people have expressed interest without counting everybody one by one (because I could do that)?
EDIT: I counted myself (decided to not be lazy) and I got 10 people interested.
