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 ?

Thanks! It's working now!

Blue laserpointer seized at custums Sweden (gothenburg). "Det började omedelbart ryka och det brändes hål i väggen. Vid undersökningen visade det sig att pekaren hade en maxeffekt på 50W." translated to english "It immediately began to smoke and it burned a hole in the wall. The investigation...

I know more programming languages than thoose I can speak:) Those I can speak is Swedish, English, German and Norwegian

I want 5 :D, hope that they will be ready soon.

If you have a lathe you can make a heatzink that will fit, I used 2 simular hosts and it was no big problem. price 3$ each.

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

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...

Are those hosts aluminum? I guess it's just one way to anodiz aluminum so I guess it will work fine if it is aluminum.

:oops: I think i used more like 1 part soda 4 parts water :D Thank's I will add more water next time.

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.

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 ?

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.
