[meteorite-list] Green LASER Pointers

[mark ford]

Hi,


Yeah I bought a green laser some time back, best thing I ever did. At
night you can point out stars as the beam is very easy to see. There are
also some modifications around on the net to increase the output power,
they ship them with power typically set to 3-5mW max.

 Usually there is a variable resistor inside which controls the drive
current, turning it usually increases the output power, or changing the
fixed drive resistor to a lower value. Caution though, overheating can
be an issue with over driving them too much, but usually they are
capable of a lot more than shipped, and are set low to meet the regs.

I managed to get mine to safely run to 10mW (measured with a Yag power
meter also bought on ebay), and when focused with a lense it will
actually burn paper!!

If you get one I guarantee you will go outside on a foggy night and play
Darth Vader Light Sabre fights, its going to happen I bet you cannot
resist it!!  -  Lol!

Gracias, Doug,

This will give me the confidence for a Chinese Ebay purchase with one of

their more scrupulous dealers.

Cheers,
Pete

Hi Pete,

The ones from China are the same ones that are imported here at the low 
price end through middlemen who will need their $ cut.  They are less 
expensive and all you have to do is wait two weeks, but I don' know
anyone 
who's had a problem and many of us have ordered.  If you do buy one
here, 
expect to pay $7 to $10 more if you are lucky on the least expensive
ones, 
and in a month you will forget you ever had to wait with your pointer in

hand.

Best wishes, Doug
