Just checked it, and like you said, it's fine. Yes but I should have at least have different voltage change, right ? But it's the exact same one, 4.9V to 4.7V. And the 1N4007 diodes were getting actually pretty hot after a long time, but the voltage stayed at 4.7V :confused: And some times...

Yes but like I said a bit earlier I tried with different diodes and even TO-220s with heatsinks to try to get rid as much temperature as possible.

Like I said on my last post I tried with different diodes (I just didn't makes any photos) but the results were pretty much the same. Apart from this, I don't have such a resistor but thanks, I'll buy one soon! Yes I'm going from off to on. Are you talking about the ripples of 300mA peak to...

The input signal to the driver comes from my laboratory power supply, which has an extremely clean output so it doesn't come from that :/ That's what I thought for the voltage change so I tried with some 1N5408 and even with some MUR1520 (with heatsinks!) to eliminate the heat parameter but it...

Thanks! Well it's more like 200-230mA average (the very big peaks are not always here) but yes that still is enormous! I was planning to use it with my NDB7A75 before the tests, I changed my mind afterward :p

Ok no problem ! Doesn't the forum resize the images automatically accordingly to the screen size ? I'll change the resolution when I'm back home.

Hey ! I recently bought one of those cheap laser drivers: 5A 12VDC Power Supply Driver for 445nm 450nm 3.5w NDB7A75 Blue Laser LD with TTL Not to use it as an actual driver but to perform tests on it. But hey, if it works fine I might use it with my NDB7A75. So I started by making a test load...

There is no hole in goggles and they don't even heat ! The light just go through it. The dot is a bit dimmer after going through them but that's all.

Hey ! I didn't know what to use as a title but here's the problem: All these links: are leading to a down website, which is useless: I just wanted to point that out.

What a really nice build ! Bravo !

Thanks ! Yeah that's exactly what I did :D I'm going to test those ones next, with the money they refunded me. I asked them (you can see it in the questions tab a the bottom of the page) if they were enough for a 2.5W laser and they said yes :crackup:

Oh ok thanks !

Ahah thanks ! :) Try what ? I only have a 405nm and some 650/660nm lasers, I'm a newbie :D Yeah, that's what I'm going to do. I'm gonna buy some Eagle pair or those ones (the LSG08. I would prefer to buy those ones since there's way less shipping fees, but I didn't see any review on it, plus...

Yes thanks I edited :whistle: Well I saw here that I need dark green glasses for 650/660nm lasers. Plus it says 600-700nm on banggood. I guess he meant dot ^^ At the end banggood refunded me and I guess I'll buy Eagle pair ones. It's just that since I'm in Europe I have a lot of shipping...

Hello ! Here is a REALLY quick test, just to inform you guys that those glasses which are supposed to protect from red laser are aweful ! I use a 250mW (not sure about that, I bought it from the same website, here) To focus the laser they are fine but when talking about direct hit, look at that...
