Sorted Cut into 9cm strips, staying in very nicely. Took a bit of force to get them in, but that clearly will pay back with long-term grip. Didn't use any tools.

Good on ya!

Some people like 'em. Some people don't. None of mine have the inserts in them. I do like the look of the black inserts on a plain barrel though.

Peace,
dave

200mW of violet light will do that

Have fun, but be careful 8-)

Just thought I'd show all you what I've been up to today with the laser I bought off Dave

Burnt paper very easily... my Hulk Ultra 400 can't do this.

Glow lights... better seen off the camera really.

I did also wonder why your battery was about 2mm taller than the other ICR18650's I have.

Other stuff I've been doing with the collection (more boring though).

I'm pleased that you are enjoying the laser.

Yes the baatery I supplied to you is taller than your other batteries. *The one I supplied is a protected battery. *It has a protection circuit that prevents the battery from being over-charged or over-discharged. *Look at the portion of your picture in the circle below. *You can actually see the circuit on the bottom. *That's where the extra length comes from

It has fine, insulated, solid-copper wires. *You can easily bend them. *However, if you repeatedly bend them, the copper will fatigue and break.

Wow Dave, all this time and I finally caught you in a slip-up, haha! ;D Never thought I'd see the day, you seem to know everything else. So I'll relish that opportunity to actually teach something to one of our resident experts. :P

That wouldn't be fatigue, that would be work-hardening. Fatigue is when the weakening/breaking of a metal is from excess repetitions of elastic deformation. This is the kind of deformations that comes back, a la a spring. If you are only elastically deforming something, it goes back to the original size and shape on its own when you remove the applied force, it does not permanently deform.

Bending a copper wire changes the shape of the metal, so that's plastic deformation: the deformation stays when you remove the force. Doing this over and over does make the metal more brittle and easier to break, but due to work hardening, not fatigue.

And that's your materials science lesson of the day. [smiley=thumbsup.gif]

Is this FS thread still hanging around?

I guess it is.

Only the Newwish style 110mW PHR based laser left


My last Kryton is now sold.
