Well, don't connect out and adj right at the pins. You should connect them after the resistors, and then connect the load at the adj pin. ETA: It looks like you have ground/- connected to the regulator +in, that would make a short circuit. You don't need ground for the regulator.

Overlapping legislation is nothing new. Maybe the purpose simply is to emphasise the point about pilots really not liking being blinded by lasers when near the ground. Fine with me.

You size and shape limitations does not really match a green module. Perhaps you should try get hold of a 5mW red module and mount it in one of those flat led lights intended to be stuck to a surface with double adhesive tape.

twhite828, :D Yes, surgeons are not always the most technical types. But it does remind me of a bridge offices telling about his tour at a hospital (they are supposed to be the ships doctors.) He asked a surgeon what the big difference was between the surgeons handheld drill for bones and the...

Welcome to the forum. :)

It sounds great to go on vacation with the wife and two 20-year porn stars. :) The cocaine sounds more risky, at least he looks like a good reason not to overdo it. You know, the wild eyed megalomania thing.

It was likely a CO2 laser, the wavelength (10.000-some nm) does not penetrate the eye, and does therefore not get focused by the lens onto the retina. A reflection could still burn the corona badly so I don't understand why he would not wear something, like a cheap pair of clear plastic...

In order to identify a diode you have to know where it comes from, then you can check the relevant datasheet or forum post to seen the correct + and - pins. You are going to need the datasheet anyway to know how many mA to give it. To see if one is burned off you can try the diode check setting...

It sounds very interesting, particularly if cost plus shipping could be held below the Danish custom limit of app. $14. I would want several packages.

Then you have a problem, this is a quite expensive hobby. Also, when you write on a forum, you should take more care with your spelling. People are less likely to respond to a poorly written post. I assume you have a full keyboard and are not using a phone?

It looks like you have an IR diode, it does not get any brighter.

I have not seen that type before, and it looks broken to me. What is the resistance between each leg? Does your meter have a diode setting? What colour was the laser?

I agree. A DDL driver gives pure DC so there should be no problem, the KHz/Mhz pulsed DC from a buck/boost would likely give problems.

It looks like it doesn't really matter any more. The "try them all" approach have burned/melted the small wires that is supposed to connect the centre bit to the legs. Can you tell if there have been a leg on the left, maybe broken off during dismantling?

I have one, from Priceangles. It takes a P60 dropin and I have replaced the stock one with a red single mode drop-in I had lying around. It looks pretty cool, but will be even better with a 600lm red LED and some optics to give a narrow beam. :D

But hopefully in a smaller and cheaper projector. At $200 I would likely end up with just one of each.

I doubt that cobber tape would give a good enough fit. At least compared to a heatsink that is machined to fit. And yes, the answers here have shown me why the idea a p60 laser dropin is not used.

You could gut a green module and install a 445nm instead of the IR one. :D

You have a point there. :(

I wonder if the rather long tread of some green modules would enable one to turn it into some kind of beam expander by using two lenses?
