Need Help! on my 20mW green laser module.

[ParangSalawaku]

Hi there,

I recently bought an 20mW green laser module.
My problem is how do I power this thing I know it uses batteries but which one?
the specifications are:
20mW
532nm
250mA

And one last thing ho do I connect the power source.
my first time trying this out.

thanks.

Can you tell us more about the module?
Where did you buy it?
Does it include a driver?
If so, what is the voltage requirement?

Okay I bought it from this site DealExtreme: $8.81 20mW 532nm Green Laser Module (3V 11.9mm)

there is not much info on the laser module itself
the voltage requirement is just 3V some said if I go over that I will damage the module.
i hope this is usefull.

Welcome to LPF.

Just use two AA 1.5v (serial) or two AAA 1.5v.

The review on DX say that the wires are blue and red, with the blue being the +.

It might be true for yours as well, you could get a battery holder for two batteries?
Or just use some tape?

You could also start reading up on how to build a laser, there is plenty of material on this site. Just be careful, it can be an expensive hobby.

Use this: AA/14500 size battery holder w/ 6 leads, cover and switch [BH3] - $2.39 : Modwerx Shop

Is there a way to operate it, like say in a spirograph, with it wired up to a switch on the outside?


Like if you didn't want to use that little button on it, if you were mounting it within a spirograph.

 

[Toke]

Yes, but you will have to solder a bit of wire across the connections on the button.

(or maybe improvise something with a bit of eraser and tape to hold the button down. )

 

[warrior24769]

Is there a way to pop off the button part and solder under it?

Or is that what you meant?

 

[Toke]

It is possible, but it would be much easier to short it where it connects to the print.
