??? Michael, where was trust an issue here? :-? DanQ

They're worth a lot to the people who don't have 'em but want one... back when the project was happening, our source for the heads ran out, leaving a bunch of folks wanting but not getting. That head makes an excellent power meter, and much cheaper than buying a comparable meter. I wish I'd...

:o :o :o :o you may just want to auction off those heads! (you will be asked to sell them) ;-) DanQ

in this case a compromise is in order... fast is safer, if done well! ::) I didn't mean, above, to imply that there is no sensitivity to heat - just that they aren't butterfly wings. or Icarus' wings, is closer... Better to have a bit extra heat, than shaky hands nervously stumbling in trying...

can't help myself:

Re: 405nm AR glass lenses - fit AixiZ  FEELER ooh... an opportunity for extreme obxcure punditry! (not directed at anyone!!) Hey Igor, I'm just sticking this dippy little post in here, to see if you really read all these pages of pleading for your wares... I do hope you are either having fun...

I've used this 6mm one from Aixiz -- I think... the one I got last year had an adjustable lens, but their page says 'fixed'. Their website has changed since (but not in my opinion much for the better) It would be worth an email to ask for clarification, the little ones I have are great for...

Somebody suggested a while back, to just use something like fingernail clippers to cut it off bit by bit. That sounds good to me. But... I normally do like most people, use an exacto blade under the circuit and pry up while heating all 3 pins. The LD's aren't really hypersensitive to heat, in...

maybe... but first, there are some very cheap multimeters that are also very good, for basics. I have one from RadioShack a while back that was about $5 (US). Anyway... do you have any loose LED's? resistors? if so: - solder a resistor to the negative side of the LED; that would be the short...

Re: Two, 10280 200 mAh batteries available ??? he's not that far south... :-? ;) ;D

It would be best to do that, any time you are working with static-sensitive electronics - which includes laser diodes, integrated circuits, FET's, and others... That said, I must confess that all I do is, if it seems like a static-y day, I will ground myself by holding on to s grounded metal...

good - that's what we're trying to convey right... words are the medium we're using to convey the answer... I'm not going to waste more time on this... but maybe you should know, it's not wise to argue with the Old Farts we've been through flame wars that would curl your DNA... but...

Good! ;) now go learn a little more, so next time you won't need to fix it! ;)

it sounds like electric circuits are new for you? if so, I'd suggest some basic learning/experimenting. You'll save a lot of time and money if you get a basic background before trying laser-making. You can start with just a switch, some batteries, light bulbs etc.... or better yet, find a kit...

I'd like to hear from other people who've ordered from VV. Good, or bad? I recommend you watch out for them, they can really nail you for shipping multiple items! When I ordered several lenses, they charged me their regular shipping rate for each one! I did see that on the checkout page...

being an engineer, you will understand that for a system working beyond its design parameters, those factors are highly variable and dependent on specific characteristics of each individual situation. Which is a long way of saying that I don't know the exact values for your case - which is why...

yes, I know - the problem is, most of the people saying things like that are not long-term, knowledgeable LPF members; or knowledgeable people who count on this: complicating matters is the fact that under certain conditions such practices may be safe. Note the double modifiers there! The...

::) ::) ::) hasn't this been said enough times? not to you specifically, but about 12 times a week: DO NOT DO THAT :P

Consulting Arborist - not too many know what that is, so: I figure out stuff about trees. Why is it sick / how to make it better; risk evaluation / prevention ("that branch is going to fall on your house within 5 years"); construction planning (to protect trees and buildings from each other)...

yes - depending of course on how much different the powers are - but that's only for human skin like mine ;-) I just now tried it... 100mW blu-ray and 200mW red, both focused to a spot about 2mm diameter, from 6" away. The blu-ray stung after about 5 seconds; the red felt warm after 20-30...
