Mini-match gets infinite brightness via QTC

Oh yes! That is a nice mod Match! Well done sir. And thanks to Don for obliging with that QTC material.

Very sweet man, puts what I did to shame - you put the flashlight together AND did the QTC.

that looks awesome..i'd love to have one..

Wow! Match, you never cease to amaze me with your sweet creations! I just popped a piece of qtc into my e07 as well and it is absolutely awesome! Now I need to begin a project such as this mini mag!:slight_smile: well done sir!

Just a thought, but this would work with a standard incan AA-mini mag with an LED upgrade, wouldn't it? I mean, something like a Terralux mini-star extreme wouldn't be any where near the brightness of Match's masterpiece, but unfortunately not all of us are blessed with his modding skills.

Nice job...... I want one!

Excellent! Now just out of couriosity... since the fancy material used act as a resistor and the more you press it the less resistance it has.... how did you manage to "prevent" the loss of energy on the resistor?

*** and low only draws 1ma from the tailcap ***

You probably used the quantum goop as a variable resistor in the driver or it's a trade secret? :)


As I understand it, the stuff either passes current or doesn't - there's no resistive heating involved. Since a 4 x 4 x 2mm pill of the stuff can handle 400W there is clearly a different action from the usual resistor. But i could be miles out, it is 29 years since I had to do quantum mechanics and I was never any good at it.

What I'd like to know is how it is mounted in the light.

If the stuff does not have any noticeable power loss when current passes through ant any pressure level it is truly an outstanding material.

Fascinating!

The technology that makes touch-screens work adapted to flashlight applications. A loss-free dimmer switch... I'm getting ideas...!

Now, where do I get the stuff, and how to work with it?

There are various places sell it, or PM me.

Amazing as usual , how do you manage to not burn the emitters with two 14500 , relying in the internal resistance of the battery ?

Match is my idol.

Wow! Thanks for the positive responses, Guys! Let me try and answer some of the above questions:

Yup. I actually used it first on a bone stock incan mini-mag, and it worked fine. Lowest setting would barely dribble yellow light out the end...

By using fairy dust and unicorn piss.... On a more serious note, I think there may be a misunderstanding out there on exactly what goes on in a series circiut. Edit: Just deleted huge wall of technical text...

Think of it this way: Adding a QTC is like having variable internal battery resistance. We're only controlling how much current can come out at any given moment. In the same way that the "internal resistor" of the battery doesn't waste power, neither does the QTC.

I'm still using the single mode buck driver from the original build.


I agree with that!

Cool! are you physicist or something like that?

It is truly a wonder material if it acts like a current regulator per se without wasting energy. Still have my doubts that the losses are so small but could be.

Hows the liftime of the thing? 1000+ squeezes?

"Cool! are you (Don) physicist or something like that?"

He has a degree or vast knowledge in almost anything that has to do with science or chemistry and beer or ale (never understood what's the difference)

Traditionally here, beer has hops in it, ale doesn't. Though this seems to vary around the world.

Oh that's it? I guess ale is less bitter and aromatic? Not something i would like a good beer lacks...

I already did. And am happy to pass them on at cost. I can easily get more in under a week in people want them.

Today's sterling dollar exchange rate is as bad (for sterling users) as I've seen it in years. They cost 18p each and 20 of them will ship for 76p airmail. They are very small and light so 20 of them will weigh less than 2 grammes. I don't think I have 20 uncommitted so I'll order some more (Minimum order works out at 70 of them).

Paypal is fine for payment.
