Dave, very sorry, I didn't even see that I had received a PM. I guess i deserve the public warning. Coherent Light, I had posted my build briefly in this link: http://laserpointerforums.com/f67/super-simple-a140-project-61577.html Maybe my resistor is too small in terms of watts? i think...

Merged multiple consecutive posts Man, If it is a zombie, im gonna be pretty upset (who wouldnt be lol) I mean, that means i'll have to get another one since the vendor doesn't do returns. And yeah, Ive even used an acrylic magnifying glass and it hasnt melted either. I mean, it doesnt make...

Merged multiple consecutive posts but see, the whole thing that confuses me is that i have an acrylic lens. If i am really pushing close to 1 amp, then the lens should melt. But it works fine. It does get warm after about 30 seconds. So basically I need to make a battery pack that will have...

Merged multiple consecutive posts I have seven soldered together, but im connecting it at the forth diode. The 9v battery I am using is one of the new lithium 9v. Apparently they have more current then the regular ones. I am trying to get some stats to see if this explains things. How does...

ok so i ran the test properly and got a little over 900mv

Merged multiple consecutive posts Why would that kill the driver? Even with a test load you cant be 100% sure if the regulator is putting the right current for the diode. I mean, Im sure there is the ever present problem of getting a capacitor discharge when reconnecting the diode to the...

When i first created the circuit, i used a testload. It is 4 diodes and a 1ohm resistor. I basically followed that same pic you posted. I had found it while researching how to make this. The reason I said that i was not sure if the resistor in the circuit may be a 1 or a 2 is because the color...

very sorry, I meant 10Amps. There are 2 settings, one for DC and another for AC. I am using the DC side (the next smallest demoniation is 200m) Currently im testing with the diode itself ( since its a working laser i dont have to worry about blowing the diode...right? ) How long does it take...

Merged multiple consecutive posts ok so i took a multimeter reading again and it shows .9 when i have the meter set to the 10amp setting. I figure that means 900ma. Am I reading this wrong? :o i put the meter between the driver and the diode this time Ok, so i had a makeshift battery pack...

Merged multiple consecutive posts I made a testload out of a few diodes and a 1ohm resistor. But It never behaved just as the LD would. Plus I figured since the diode could handle all those miliamps, I could get away with just using a 1ohm resistor to regulate the voltage. I have one of the...

Merged multiple consecutive posts http://laserpointerforums.com/f67/super-simple-a140-project-61577.html thats what it looks like. but I have a heatsink on the regulator now. are you saying, that as bright as this mofo is...im barely pushing it? I guess that a good thing since I just now...

Merged multiple consecutive posts See thats the werid thing. Ive only turned it on at the most, for about 30 seconds. The lens has gotten "warm", but it has never gotten hot. There is also no smoke or burning anything from inside the housing. The dot on the wall appears to be properly focused...

Hello Everyone, I have a little 445nm a140 LD in an aixiz housing with an acrylic lens. I have about 900milliamps goin to it. I have seen posts where people say anything over 300mw Must have a glass lens. But I have not had serious issues with it. I do feel that the quality of the beam is not...

Yeah thats mostly what ive done.

Shamefully, I do not. I have a pair on order. I have only used this very sporadically to aim at the sky (away from anything moving up there). Its astonishingly bright. --ICWiz
