Hey bro, I'm new to this, and I want know the estimation about how long will the button cell will last if I use for red laser module 650nm 5mW? how many voltage usually you use for that kind of module? :thanks:

:eek:

can u show me the link? :thanks:

:angel: no way I'm going to do that, lol I already said that I just want to point to a screen so the other surgeon can see the spot I pointed....

:eg: muahahaha (evil doctor laugh)

for a secret operation :cool: that's why I also need a security system, and I control the laser (on/off) using wireless transmission (foot switch)... do you have any idea to prevent any accident? :thinking:

thanks dude! :bowdown:

:crackup: lol, I just want to use it to point into a screen while I use both of my hands, for some operation (real operation).... and I do need a good form, just like the "locutus" :crackup: *seriously.... so I really cannot use a duct tape here... cos it's for real :thanks:

:thinking: Hm.. I'm going to use it continually, I can't duct tape my head every time, lol but thanks!

Hm... So I can use both of my hands :crackup: I just need to turn on then I can do something with both of my hands... or do you have other suggestion besides using headband? :thanks:

Yes, that's also what I mean... :thanks: So, if I have two 1000mA.h battery (AAA) and it works at 30mA, how long will it hold? 30 hours? :thinking: Hm.. Can you give me how to calculate the power (W) I'll use with a certain red laser pointer? in this case, 650nm and I use AA battery with 3V...

Hi Laser Guys, I'm a newbie for laser topics here :D I just want to ask, how much specifically does red laser pointer energy consumption? and how much energy output does it emit? :) thx again!

Hello, newbie here, do you have any shops that sell besides line generating lens, coz I need different pattern while using 3 laser pointer at the same time :thanks:

where can I buy that stuff Steve? can I get a picture of it? coz I'm newbie and doesn't really have a clue... :yabbem: yeah, just like I wrote above, it's only for operation, so I only need 5-10m and just like normal laser pointer, its function is just to point something :D
