Your physics teacher is awesome. Just sayin'.

Hmm... Well, I don't think there is an IC like that in a through-hole package. What I'm thinking now is that it's definitely possible, but it requires you to wind your own toroid, and the component count goes up considerably. I'll have a stab at it today.

Welcome to the forums, Cad602 :) The main advantage of laser drivers you can buy seems to be size and convenience. There are other ICs you can use to make constant-current drivers suitable for laser diodes. The one I'm looking at now is the LM2621, which is capable of boosting, so you can drive...

styropyro: Is the FAP any good for DPSS purposes? I know I have very few posts, but I've been active on laserchat for quite a while.

I'm gonna speak out here against the advice to carry a gun. Don't. Do you know what kind of things happen in jail?

Eek! Good to hear you're unharmed and lost no cash.

the15thwiseone: The optics in the PHR sled are dichroic mirrors and beam splitters, and I think there's a diffraction grating as well. I'm not sure what you mean by "beam contaminator". The collimation and focusing lenses are not very useful; you're better off using a standard aixiz acrylic...

100mW of any wavelength burns the same? You sure about that? ;)

405nm tends to burn better than longer wavelengths, because it has higher energy per photon. They don't use red or IR in tanning salons, do they? :P Silvershot: I'm not such a fan of the hotlights host, but it looks like a nice build :gj:

If only one end of the capacitor is connected, then it's useless.

I'm sorry for your loss, Jeff. :(

I got my wire today! Well, I got some green instead of red, because I got the last 8' of red, but that's not a problem :P This stuff is great! Thanks, Flaminpyro!

If I were you, I'd adjust the layout so as not to require the mirror, but that's just me. It's certainly a nice and roomy case, have fun transporting that :P

Over 9000.

Low-Q: Ultraviolet light is not actually black, some people simply call it that because it's shorter than UV and sounds cool. IR is also invisible, but nobody calls that "black".

hydguy: I think it's called something like perception of relative luminance. If, for example, you project a white rectangular box (with a hollow inside) on to your white screen, the inside will look black, but the portion of the screen that is outside the projection area will look also look...

Psychoo008: give people cancer?

Y'all should head on over to #laserchat on irc.ecnet.org, if you're familiar with IRC. Myself and most of the other LPF Sydneysiders hang out there. Normally there's an easy web-chat interface at laserchat.org, but that seems to be down at the moment.

r1lazer: I live in Leichhardt :)

Hi r1lazer and Narcissa. R1: What part of Sydney are you from?
