Hey JayRob, It has been a while, eh? I'd like to buy a couple more of your 405 G-1 lenses. Could you PM me with the details? Kurt

Isn't it interesting that the more these incidents get sensationalized by media coverage, the more it happens? And, does anyone here suppose that the people who run the media services don't realize that sensationalizing these kinds of stories leads to just that? Like most of these crusades in...

Oh. Sorry for raising anyone's expectations. :o

My self made mug-shot. Can't decide if my glasses are crooked, or if it's my head...:undecided:

Using the turntable was purely laziness - the other alternative was searching through my junk for a motor :o. I figured since I might be a little shy on power, best to blacken the kernel, just to make sure, but this wavelength is usually pretty well absorbed by most colors. No video, but if I...

Here is the look with the smooth cap pressed on: Here is the entire mechanical disassembly: In contradiction of my earlier statement about removing the module through the lens end - Don't! My second attempt ended with broken-off coil and broken pot whilst attempting this. :can: Some are...

I think it was "The Dancing Wu Li Masters by Gay Zukav". Maybe I shouldn't have said "current" the book is 30 years old ...:o

It was a blu-ray laser shinning in the dark - not very memorable, so I didn't try to hard to find it. LOL

Hey all, thanks for the comments and generosity! It took me a minute to understand what you mean, but you know it does look like the focus ring could be pressed or made to fit into the end cap, and if the skirt were cut off at the bottom, it just might work. After I am done modifying a couple...

Like may other members here, I couldn't resist buying a few of these cheap 405nm laser pointers off Ebay. Upon testing them, I was pleased to find they all output right around 50mW with a couple of Ni-MH AAA batteries. That is enough to light a match with 405nm if focused to a fine point. The...

Isn't the current thinking in physics, that the very tinniest particles are actually nothing more than patterns of energy?

Been ill, but now I'm back. Still Kage. Thanks to LPF for keeping my login all that time. This forum definitely Rocks! My old avatar and sig were lost in the transition, so they are different now. Kind of still working on the sig... So, Hi everyone!

I did. It does. WOW! :eg:

Based on this, the overall efficiency could be derived by: 5.6/(18.4 + 5.6) x100 = 23%. An good example of where a switch-mode buck regulator could vastly improve the efficiency. Some of these approach 95%.

I use a LOT of these batteries and build some of my own chargers, and I have to agree with Bionic-Badger. 4.15 to 4.2V is the usual target voltage for charging these type of lithium Ion cells. They are pretty much depleted by the time they reach 3.3-3.6V. If discharged below 2.75V, they can...

Nice job Netscott! It really is great to see someone doing things beside burning holes in stuff. I was actually able to reproduce this at home on my workbench, using a phonograph turntable to spin the popcorn kernel. I don't have 2 1 watt 445nm lasers, but I do have 1 1W and 1 500mW, so I...

This is a great deal. I bought 5 for "stocking stuffers" for $8 ea. They arrived in 5 days including the Veteran's day holiday. All were between 35 and 50mW. Remember these are powerful enough to damage your eye with a direct hit, so be careful :thinking:

Re: Thread topics: make sure they describe subject not "woot!" or "check it dude" DUDE!! That is So appropriate! :beer:

Donation sent. My first time! :o
