At the beginning of this week I made a WTB post here and after a few messages back and forth I made a purchase from mhemling33. I wanted only a green but picked up a nice deal for two lasers and some crackle marbles. The green was a custom build, and I am impressed at how nice it is. The extra...

I bought another host off his site since I liked the LPF special has on here. I got it in the mail but the dust cap was missing. I asked if it was suppose to be in there cause I wasn't sure and he said it was. So without anymore questions he is shipping one out. Anyone looking to purchase from...

While lazerer is out of stock again on the one I was thinking about, I'm looking on here if anyone has green laser pen in the range of 100-200mw.

Can be deleted.

While I was making my laser, the button cover got ripped. So I'm throwing this out there to see if anyone has one.

After I built my first laser I thought about the old lasers you got for running the pets around. Could a laser have a fixed focus like one of those and still be able to burn if the output was high enough (able to burn through an adjustable focus lens)?

I just finished my first laser the other day and I have a question about the negative connection from the battery to the driver. I couldn't tell where to put the negative so I just made a little coil of bare wire (which contacts the battery) and soldered it to a straight piece of wire up along...

If I set the current with a one set of batteries will it change if I use different batteries if the voltage changes. It will still be in the range of the driver plus diode required voltages.

I'm wondering how the shipping prices are for those two sites. I've ordered from Newark.com and got funky shipping numbers. At the time of the purchase the shipping was stated for once price, while my invoice said another price and lastly my card was charged a third price. Now that p*ssed me off...

Just curious to see if anyone has a 100 ohm pot and a 4 ohm resistor for the DDL driver. Then a 1 ohm 1 watt resistor to make a driver test load.

I saw the kipkay video and decided to make one, but not before reading here that I should use a driver, at this stage I'm just gathering materials and knowlegde. With that said I'm going to make this driver laserpointerforums(dot)com/forums/YaBB.pl?num=1185701612 . Now my question is, will this...
