Re: 405nm AR glass lenses - fit AixiZ  FEELER 2 405 blu lens' please :)

Yeah, like the 750 watt heating element in there which i'm using to heat the place!

Darn, that makes it an IR right?

Someone should take them to trading standards or something if the output is not within the stated range over a large number of products.

Dam i didn't think of that, I've ripped all that out now as yes there was a motor with a rotating mirror, i might have to put that all back together... Also the printer is scrap so no worries there. Is there anyway to determine the max power ie therefore the max current that can be put into it...

Hey all, Was given this printer recently http://www.brother.co.uk/g3.cfm/s_page/50670/s_level/31150/s_product/HL2030ZU1 Anyone have any idea what sort of laser I've got? The box indicates it's a class 3b and gives a warning of invisible laser radiation so it is likely to be an infrared? If so...

If you assume that nearly all the heat dissipates into the axizs module and they have a good thermal contact, then then temperature of the module isn't going to be much lower than the LD itself although the junction temperature may be higher. Only a very small wattage is being dissipated from...

Ack, my 2nd diode just died but I have no idea why. All i can think of is that I ran it at too high power (280ma) for too long, although I had a big 120mm fan resting on top of it which kept it at room temperature the whole time. Is it advisable to lower the current to 250ma when leaving it on...

Re: 4x Rechargable CR123 @ 3.7v @ 1000mah + Charge Thanks for the warning, I have now found these which are safe and are still pretty good value...

Ignore this ..

While I've been testing it, I've had the laser at the floor at the side of a desk and made my self 'hidden' round the front side incase of reflections. It's worked very well so far, lol. I can then stand up slowly over it check for reflections.

I focus the beam to the shortest range possible with the lens fully unscrewed when burning. I will try something like that with the smoke as I don't have any goggles yet, I have been very careful so far though.

The Aixiz modules are pretty good although there is still a fair bit of light lost. I understand what your saying about the matches yeah, I finally managed to get one to light from about 5cm away after colouring it black, it took along time though. Can you explain the focussing with the smoke...

I didn't to begin with and realised that some light was being reflected, however I read that the red safety matches could be lit with only 160ma, without colouring them black. Are you able to light matches without colouring them? I actually don't know why it is now burning and it wasn't...

The problem was that killed it being an idiot and not thinking that I would be zapping it with the fully charged capacitor when connecting the LD with the circuit already on and the cap at the regulator end. 320ma sounds very high, other forum members who know more than me will be able to...

Thanks for the continuted help, I'm very impressed with the members of this forum, it's one of the best i've come across :) I now have the LD burning and have cut away the plastic, I'm trying to burn right through a floppy disk at the moment hehe. IgorT, in this circuit, the voltage is fixed...

Thanks for all the help, I'll get the circuit all sorted tomorrow and might leave a pot in there. The current source seemed a little unstable even though the diode wasn't getting too warm with surges up to > 270 ma but I was quick to rip off the wires at that point. I think the regulator was...

Thanks for all your replys, it turns out I had blown the first LD, but I now have the 2nd working fine in an Aixiz module, apart from tha fact it won't burn anything even though focussed within a milimeter or two :S Regarding the PSU, I was only using the adapter to test it and wasn't planning...

Thanks for all the replys guys, sorry to turn it into yet another 'omg my diode broke' thread. Benm, I did use an antistatic wrist strap when handling the diode and soldering so hopefully that wasn't the case. I had two wires on the LD an nothing more, the regulator circuit was seperate meaning...
