    correcting a NDG7475

    Okay, I just want to make sure I'm reading things correctly. Using the 6x cylindrical lens set, I only need those two pieces and a G2 lens? No lens goes after the 6x set? I see the Ebay listing says 35mm between the lenses that come in the set. I assume that is between the front of one and the...

    custom positive battery connection

    I was looking for something like that. Ebay items usually come up when I do a search.

    Post your random pics!

    Don't forget Germany has the autobahn. I very rarely ran across someone doing less than 130. The 4x4 truck I had would go faster than the VW and it weighed a lot more. I think the transmission gearing was part of the problem.

    custom positive battery connection

    Does anyone have a source for 26mm round circuit boards? I need one to use for a positive battery connection. The other thing I thought of was getting something like this, cutting it, and adding some solder in the middle to the positive connection along with some around the edge for negative.

    CDBEAM777, I ran across this: http://laserpointerforums.com/f49/opt-lasers-cylindric-lenses-nubm44-beam-correction-tests-96445-3.html#post1423709 Did you have a problem where the "line" formed on the opposite axis? What lenses did you use? I found these but it says they are 2x. Cylindrical...

    correcting a NDG7475

    I've been wanting to build a 1W 520 for a while now. I hate the beam specs though. I finally came up with an idea for a host which I'll try to keep under wraps until the project is finished. The problem is getting a better beam. I've been looking around and came across this. Is it necessary...

    World first high power underwater handheld laser

    Any idea when they will be available for purchase? The watch I wear is uspposedly rated for 30m. I have worn it in the shower and gone swimming with it on multiple times. It hasn't had a problem yet.

    Post your random pics!

    Talking about cars, I had a VW Polo for a rental while my truck was in the body shop when I lived in Germany. That thing had a 3 banger with a 5 or 6 speed manual. That thing barely hit ~150 km/h. That was with the engine near redline. The screaming of the engine just about put you to sleep. It...

    FAIL THREAD!!!!

    I try to be unbiased and all of that. That crap is getting out of hand on the liberal side though. The blame finger can be pointed in multiple directions.

    FAIL THREAD!!!!

    I've noticed that it quit working on a couple websites for me. Youtube works fine along with embedded YT videos on at least one other website I visit. I use Chrome and it updates every time it is reopened. I just restarted my computer yesterday and YT videos still don't work on LPF.

    Holy @#$%... $100 488nm diode!!

    Re: Holy @#$%... $120 488nm diode!! I think Adam initially told me about that. 473 also works. I may have tried with my 445 or 450 but don't remember the results if I did. I like combining different powers and wavelengths in something like quartz to see the results.

    Holy @#$%... $100 488nm diode!!

    Re: Holy @#$%... $120 488nm diode!! Here's a couple pictures of the 488 in my signature. I actually need to see about getting it repaired or finding another one. The 488 with my 589.
