Hello again folks,

I recently bought a 80-100mW green laser module from olike.
http://www.o-like.com/b2b_cpinfo.asp?id=909

My plan was to fit it into an old green laser casing that I had around, some old cheap chinese green laser used to be in there.
Now the new one does not fit, and I was sort of expecting that, it´s too long.
Anyways, if I want to put this little thing to life, how would I go about that?

3V battery, one wire to the spring, the other one to the brass? Where does the + go, in that case?

Thanks for you help!

its case positive you need to have a mount fabbed thats threaded or pressed or just somehow mounted but neg to the spring then the plus is the brass top

I don't have an O-like module handy but IIRC there are 2 solder joints to the diode on one side of the board and a single on the other, that is your case positive so you could solder the + to that joint and use the - to the spring (if you didn't want to fiddle around with mounting, etc)

Ok, I tried with a wire and it works on an old module I have, but not the new one?!
Could it be broken?

There is a little white "button" on the circuit board - what´s it for?

That would be to turn the laser on... Hook up the - end of the battery to the spring and the + end up to the brass, press the button.

Aaah, I actually have to hold the white button in all the time.
I guess I have to make a casing that uses that button function then :)

Cheers!

Either that or if the host you choose has a different button or switch you can solder a wire from one end of the button to the other, shorting it out and making it "always on" so you can use a different switch to control the laser.
