Decided to make both the cone based and razor blades based ones. Here's the cone one (will take a while to complete the razor one): Plump bob bolted to a 50mmx50mm square washer. All parts sprayed matt black with heat proof BBQ paint: Fully assembled: Side view 52mW 520nm then 1W 445nm...

10W for $18 - not legit.

I'm glad I'm not a cheap multimeter in your home - burnt, lego brick in face! Multimeters behave or end up in multimeter hell hosted by 3Pig! :evil:

I've had my 1W 445nm with the spot on white paper and didn't experience anything like you're describing. But I see one big difference between my and your glasses; yours are better with a visible light transmission of 50%, mine are only 20% so whilst I can barely see a thing maybe it spares me...

Good to see more reviews :-) Got a link to where you got your glasses? Even if they were a low OD2 then that would make your 400mW look like 4mW. Which I wouldn't have thought would be hard to look at.

Nice pics. Got any idea what you will aim your 2.4w at without burning your house!

Yeah I questioned them about that and I think that is just poor English. i.e. it has a blue ray/beam not that it is bluray (405). This was the dialog:

Just a FYI - I ordered this 10mW 445nm pen laser: "Unique 10mW 445nm 450nm Blue Ray Portable Laser Pointer Pen Osram Diode" It has just arrived and it actually is 10mW and 445nm! I'm so used to seeing lies that I found it unbelievable that this seller tells the truth! Update: I compared it to...

Hopefully USAbro will see this as funny: Don't remove diode windows with your drill arm: ;)

Wow - that is great! I would prefer a slower color change so I can enjoy the color but maybe that's because I'm an old git. I presume you're using fog/etc to capture the beam?

Please don't - you started an discussion that I found interesting and I found the mix of responses interesting. It's good to see how different people think/feel. It would be boring if everybody was the same and everybody agreed.

Yep (when spelt correctly): *********

Would be nice if beam ***** (D U M P S) wasn't censored :-)

And meeting the aliens is how you got the idea of using a laser as a weapon! It all makes sense now!

rhd - That looks great!

Sure will - I just have to run some more tests to decide if razors or a painted cone are best and then to begin constructing the final item. If razors win then I will be drilling two holes through the box section to hold the razors, if the cone wins then I will need a metal end cap as the...

After researching beam stops I decided to make one, but weren't sure of the finer details so have been experimenting. This thread covers my process so far, and will be updated until I have my final beam dump. UPDATE: The completed beam stops are in later posts. There were two types I was...

Cool - most of mine (except 2) are cheap pens so I didn't won't to kill them all. Once I have duplicate wave lengths then I will start relaxing more with them.

Really? I've been too scared to leave mine on for more than 30 seconds. The green will have a powerful 808nm diode and that size host you would assume couldn't offer enough cooling.

You've got great PR, did you have to do much to get it (other than making the watch)?
