about this part - first I have not built this but this makes sense to me "This is an easy way to take up the extra space in the barrel so that your battery doesn't 'rattle'. Since the host is fit for an 18650, the RCR123 fit is loose. Just put a piece of the foam type double sided tape on the...

only thing I dont understand is the clicky switch thingie - its just a open/closed switch, I bet it could handle hundreds of volts and 10+ amps and 1000000+ watts before it melts - its a switch as far as I know it has nothing in there to fail like a resistor so why?

I think someone should make a better driver for the lasers - a digitally controlled one that used the 3rd pin on the diodes that is never used and use it for what I think it can be used for - that is to read the current draw and adjust accordingly isnt the 3rd pin a feedback loop or whatever is...

pretty sure its not illegal to point a laser in the sky, probably not illegal to make it a design either since there probably isnt even a law that covers making designs with lasers in the sky - could be but I dont think so I would like to see a actual UFO - like from the 50's movies projected...

not so sure about welding goggles being no good I have seen and used a pair of black tinted laser goggles that looked exactly like welding goggles - I even said to the people in charge that these look like my welding goggles and they said its designed for about 400-500nm lasers so it would work...

well having glasses that are the same color as the light they are protecting from would be good if it allowed you to see the laser better I got one of those laser levels - it says 0.95mW - and it came with a pair of red glasses to allow you to better see the dot when in a brightly lit room or...

I am wondering if a really powerful IR laser could damage a camera if unfocused to the point that it wont hurt any ones eyes but will damage the camera you know as in stop paparazzi or other people spying on you without sending out a really bright beam of visible light - yea the camera should...

question about these - they look to be a $230 version of what you get for free at a taning salon - lol Laser Safety Styles - P02 | Laservision do they just block all light? because of so who needs to pay this for that

so if I wanted glasses to use for a 3 color laser build red green blue would they be brown or black tinted - because it will be a "white" laser if the beams are combined correctly so would you use something like welding goggles I have seen some but never got to look up close, they looked brown...

well I just assume the led's were around 532nm but probably not now that I think about it but the color not being a good way to identify the wavelength they protect from? is that for lasers that are not 532,445,680? as in complementary colors because I assume that those lasers would need the...

just got the glasses from OEM and they say on the paper it came with that its a maximum of 10 seconds exposure - but nothing about what happens after that I assume this is meaning a direct beam onto the lens not a reflection but I think that there needs to be some clear info about what happens...

well anyone?

I have to talk to the guys I know at work that use high powered lasers and see if I can get some stuff from them - but I dont really know them that well and I am not spsopsta be in that building without taking a safety course and I havent so I can only do it when the bosses arent around like...

so what about the aixiz ones - AixiZ they dont even have info about exposure or weather they are reflective or absorptive anyone know about that

just noticed that they are in East Lansing MI and I am in Detroit - do they have a location I can go and buy from so I dont have to get them shipped and save on shipping

so about my other question, does wearing 2 pairs make double protection - like the goggles and glasses, you know like those old people who wear the huge sunglasses over there normal glasses

so has anyone used this and do you know if it is good - iWap IUC-23 20-in-1 Universal Battery Charger Shopxtreme I need to get a battery charger for my laser I am building it uses the 18650's I was looking into one of the the charger that is at the bottom of this page where I am getting the...

since most people that are here using lasers that are handheld and have goggles they are burning things - so how long can you look at what you are burning before it becomes a problem also are those glasses I linked to certified? - I have not seen anything on the site but that doesent mean they...

yea what I was thinking also - but being a OD 7+ they are probably great I remember seeing a review of goggles and I searched for it but cant find it anymore, they showed these and 3 others

LMAO really I know what you mean but wouldnt there be all this scattered light from all the beams that could blind someone - I would assume that just looking at the beam from 10 mega watt laser or whatever would be needed to do things like cut a tree down in a second or cut steal doors like its...
