9-Volt Laser-----Easy,Cool, and FUN!!!!!!!!!

so you want to make a 9-volt laser? I will tell you how to make one. After all, i got this idea after i combine a lot of idea from a lot of Instructable, like the 9-volt from YAN9VUSBC and the laser from Laser Flashlight Heck.

Step 1 You will need...

1) 2 9-volt battery
2)a mini pushbutton or a small on/off switch from Radio Shack
3)a 650nm 5mW 12x30mm brass case Laser Module from http://mfgcn.com/_wsn/page2.html
4)a hot glue gun
5)a metal cutter
6)a pincer pliers
7)some wires
8)a solder station or gun
9) some solder

Optional:
Spray paint
sand paper
power drill

Does the 9volt burn out the laser module?

[WudWar]

The reason this works without killing the laser diode is because the aixiz housing has a current limiting circuit built in it. Using it with a 9volt is wasting a lot of power.

[Liberty92]

I use a 9volt in my laser, but thats just because my button cell battery case broke :( lol, oh well

[Xellers]

The how much power should you apply?

[i am cool 101]

but who cares?

[WudWar]

I'm just trying to help you out by saying that it wouldn't burn the diode. I really like your Instructable.

[i am cool 101]

thanks

[tater killer]

hey i am cool 101 it will still work

[recon506]

it would be really nice if you showed some pictures of the 3rd step and also if you labeled the clip from the 9v for us. Otherwise, GREAT INSTRUCTABLE!!!

[i am cool 101]

thanks

[GorillazMiko]

very good idea! but, you should add pictures at the step when stuffing the stuff in the empty 9v holder.

[i am cool 101]

i know, but i make the laser before i make the Instructable, that's why i can't show the step in pictures.

[kruser495]

your going to fry the laser diode in about ten minutes

[i am cool 101]

i didn't. my laser work with th 9-volt for about a month!

[guyfrom7up]

normally yes, but some laser diode modules have limiting resistors built in. Still I'm not sure about 9 volts.

[Trinity]

i know for a fact that this one doesn't...and if it did you are only supposed to put 6v to them

[!Andrew_Modder!]

sure that neat to make your own laser pointer! but this is actually not as good as a crap 5mW store bought 1. cause the mw-age is the same, and the voltage is actually lower, cause in store bought ones there are 3 3.7 lithium button cells (3*3.7=11.1 volts total) so your running a 11.1 volt thing at only 9 volts :-\. so you may fry out your diode, or experiance weakness.

[i am cool 101]

the button cells battery do have a high power but it don't last as long as the 9-volt!!!!!

[guyfrom7up]

actually the ones at the stores work at 4.5 volts, those button cells are 1.5 volts each. It would be extremely inefficient to run it at that high of a voltage, beacue red laser diodes take somewhere between 1.7 and 2 volts.

[i am cool 101]

you are wrong!!! those laser can take up to 12 volt! i try that with a 9-volt and two AA batteries and it work.

[!Andrew_Modder!]

:-/...

[!Andrew_Modder!]

:-\? really.. cause i have a ghetto chinese one that runs on 3 3.7 volt batterys...? thats really weird...?... i mean it came with 3.7's, and i only had to replace the batterys once b4, so it still works, it didnt burn out.. idk i guess its just 'special' LOL :-D

[i am cool 101]

it's not special, it's because that the laser can take up to 12 volt or more.

[!Andrew_Modder!]

ok lol

[HazardRush]

You're better off just removing the 9 volt and instead hooking up a battery case from radio shack that holds two AA batteries. It has the same 9 volt terminals so it would connect easily.

[i am cool 101]

the 9-volt holds 6 small 1.5 volt battery, and it's not size AA!!!!!!!!
