I have not found anyone interested in this.. I thought i would, so im gonna leave it here on LPF where it belongs. I am open to trades for this huge piece of laser, PM me, no prob. I know i'm a newbie here and trust is difficult to earn and easy to lose(for life in general), so i am willing to...

As zyxwv99 mentioned Rayleigh scattering makes a laser beam visible. It also seems that some people perceive UV better than others. Dot shape & optics are no1 factors in beam forming. In any case it seems that beam visibility is "subjective" and depends on many variables. What i don't really...

A friend found that it is an old product of Fixturlaser - Shaft Alignment and measurement instruments company. He doesn't know how old and couldn't find the specific product anywhere.. The company changed its name from fixtur-laser AB to FIXTURLASER, keeping the old logo. I will leave this up...

Here is a laser that was given to me by a German Mechanical engineer. It states Klass 3B, not sure about that... I have no way of testing its power. Beam and dot seem much weaker than a chinese 200mw red i got. However i tested outside at night and could see the dot 1Km away. The dot seems...

Big bang theory is a nice sciency/geeky series with good humor and a hot playmate. Don't watch that! trully sucks.

I was actually thinking of getting 3 of these. I could probably use them with ir or blu diodes as well yea?

I haven't got that asus drive yet, but i decided to ruin an old recorder, the NEC ND-3520A. Only 1 thread has pics for this one , and mine looks different, so i thought id post some pics. Anyone know if i can use the circuits as a dummy load driver??? The diode with the glass is......IR???

Thx man, from that i'l keep that my diode is probably still alive, as i read they are not as sensitive. But if something specific was ruined on the driver and current still managed to go to the diode it might have killed it. Anyway im not touching it again till i get my equipment.

No clue about polarities. Driver is probably set around 200mA as it was attached to a phr. I hooked it up to a square 9v battery, and wow blue light, it was very feint and weak though. And, while everything seemed to go smooth, sparks start flying out of the driver, i tryed connecting again and...

I have almost none equipment,i had a rkctr driver that i am not sure if it works, soldered wires from diode on to it, and on the other end i soldered two wires hooked to a cr2 and no light at all.

Can a a-140 die by touching a solder tip on the end of 6cm wires attached on diode? I hold it about 2-3 seconds, and felt the wires get hot. Don't have a driver to see whats going on.

I think il also buy a 24x and try that as well, hoping to get something more out of it compared to the loc. Here in greece i can buy a Asus 24B1ST for 12.99eu (could it be loc?), il play with it anyway.

Thank you, that was very helpful, i'l probably start on the LPC-815. Although i thought that a 24x burner would output more.

Thank you for your help, my main problem is choosing a red diode (sled). I can't find any info on specific diodes, for instance their max power, or with what driver they work nicely. I am looking to build a powerful (>300mW) red laser.

No one?? Should i just buy any dvd writer, and start experimenting with a driver and random voltage? searching on this forum is kinda messed up, i got better chances scanning the red laser section.
