Re: FS: LaserBee II Deluxe LPM (Laser Power Meter) - $279 shipped + freebie! how much is shipping to Brazil? i need a LPM..

their capacitance is too small to burn a diode. I bet all my m140s, they wont burn

Hello, I've done several builds lately and I've faced a real problem here. I used a m140 w/ 1,25A driver from DX in c6 host. When i use two 16340 ultrafire batteries the laser turns on and after 10 seconds it's so dim that seems to be a 5mW laser. I've connected my psu setted at the same...

That has nothing to do with dirt on the eyes. If this floaters are disturbing you visit an ophtalmologist and he'll suck them out of your eye. But I don't think he's talking about floaters, it's a black circle, you should visit a doctor, there are various diseases that can cause this kind of...

exactly, thats what I meant to say, mabe english fail. No need to do that with ceramic capacitors

Some of you may think in Brazil we eat bananas and speak indian but i actually can speak 5 languages: :D portuguese italian english french spanish

1 minute sun exposure = 10^6 DNA damages Normal humans (exept for xeroderma pigmentosum or cockaynes) can handle very well acute UVA/UVB exposure (lasers have only UVA that's the risky one), there's barely no risk of getting a skin cancer while ocasionally hitting your skin with a laser. I...

Even not shooting IR this pens can still be dangerous. Most of them are overspec and may reach 50-80mW.

I suggest a ceramic capacitor, they won't burn your diode if you don't short the leads before running it. They have a very low charge. By the way: Great forum name you got there

Re: 1.9W 445nm SH-032 (New :) Once I had an aquatic turtle, when i bought it they told me he wouldn't grow. In about one month it didn't fit the aquarium anymore. How come your does not grows in 3 years? edit: totally off laser topic

Re: 1.9W 445nm SH-032 (New :) I can't even imagine a blind turtle.

Re: 1.9W 445nm SH-032 (New :) Did you really shoot your laser at the aquarium?

I guess a lathe does not needs that much power to work, even on metal. A 1500mm (a professional quality lathe) works with about 2hp that equals 1400W of power. We can buy home drilling machines with about that power. A good bit is important for quick machining, but of course the power...

By the way richard, what's the brand of that lathe?

I already have some HSS bits here at home. I'll save more money and buy a little lathe but not that from DX.

Flaminpyro's is too expensive. By the way, that PSU i sent you trough PM is manufactured here in Brazil, they have a website, manuals etc... They look serious, and i think i can return it if it fails. I'm in serious doubt...

In brazil i can buy an used cheap lathe for minimum $700. That's why I was thinking about getting this. Gave up already

The hole on the heatsink will be made with a 12mm HSS drill, it will be exactly 12mm. I don't see your point

yes, i have two test loads, one from rckstr and one I've built myself. I'm looking forward to buy one of those 'heavy duty' ones, i'll put it on my next cajunlasers order.
