    Hi DTR. I am thinking on building a locator beacon for underwater use. I saw you had some nice diods. Do you have some suggestion on what to use ? I want a 0.5 second burst that repeats every 5 seconds, just as a beam. Do any driver have that feature ?

    Question for the firearms afficianados out there.

    The desert Eagle uses the gas from the explosion to reload, that's why it's quit nice and does not recoil so mutch as some others :D

    Question for the firearms afficianados out there.

    My own favourite is the "Baby Eagle" and I use it with 9mm. I have been doing some "practical shooting" earlier in my life so I know a little about handguns. If I were to go into bear country I would at least buy a .44 or .454 revolver, the Desert Eagle .500 is nice also but it's a little...

    De-annodized Hotlight!

    It did for mee, I must have used a solution that was to strong then cause it realy was a lot of bubbles and the exposed treads did not fit at all like before. And it was pure aluminum, I used nitric acid to test that.

    De-annodized Hotlight!

    Okey, but tell us what that ingredient is please, so we can use it:) But one question remains, you must get rid of the old aluminum oxide, and what eats up aluminum oxide but not aluminum ?

    De-annodized Hotlight!

    I user caustic soda, and a rather strong solution. But remember to proteckt threads and parts that needs a perfect fitting, this because the caustic "soda eats" aluminum. I use a "hot glue" gun to protect treading.

    GB: 2$ copper modules ALL SIZES CLOSED

    Re: GB: 2$ copper modules ALL SIZES I measured some azix and found that they are smaller than 5.6, then I used my lathe and made a test stick that exactly fits the azix, and I use this to check the pressfit for the 5.6mm diode. I make it with a 5.5 milling drill, and just press sideways a...
