    Stripping Anodise With Hydroxide

    Depends on how strong the solution is Cheech, also keep in mind that CS affects plastics too so avoid Q-tips with plastic "sticks" if possible.(it tends to destroy the joint between the tip and the stick) I'd say give it a go with a test piece before trying it out on your Laser to be honest...

    Homemade CO2 laser

    I've been away due to work but I gotta say that is IMPRESSIVE Henry!! Brilliant piece of work and I can think of a few people who will be watching with interest ;) If you need tougher electrodes the ones in the standard tubes can be smashed out and are tungsten :) great stuff all round...

    Medical Flight Hit by Laser!

    I'm stuck without any diodes :( But I do have 7.5Kw of IR running happily in front of me :)

    Medical Flight Hit by Laser!

    The only danger from IR is the lack of a blink reflex when compared to visible beams. For the Nuclear guys reading maybe there should be an auto SCRAM (Safety Control Rod Axe Man) system fitted to $5 Ebay pens that electrocutes the operator if they point it at an aircraft :) cheers Dave

    Homemade CO2 laser

    Good news and a great choice of Uni, it's been some years since I attended there but I doubt it has changed much :) cheers Dave

    New Zealand Laser Law Change - DUE March 1st 2014

    Hiya J, It's never about what is right or stopping dangerous behaviour, it's about appearing to do something to make the underinformed public feel safer in their daily lives (note: member of public = registered voter) The only way to win this kind of situation is to appeal to the public and not...

    New Zealand Laser Law Change - DUE March 1st 2014

    In answer to the "how will they prove" questions... They won't...it's called probable cause...they will simply seize the item and ship it off to some lab somewhere who will write up a nice big report on how your death ray is illegal. Much the same way they do here in the UK, The "reasonable...

    Laser-Aircraft events

    Likely why your not a pilot :) Your miles up in the air inside a pressured thin skinned tube with 300+ lives that are your responsibility, passing through an atmosphere that would kill you in seconds with your arse strapped in a cigar tube that weighs 200+ tonnes with 2,000,000+ parts built by...

    Laser-Aircraft events

    That's no cheap kiddy laser my friend. At 1/2 mile the human face is a VERY small target and if moving even smaller. It's unlikely even a simple mount would be able to follow a human sized target at 1/2 mile. A laser fired at the general direction of an aircraft is a "criminal offence"...sad to...

    class V (5) laser build specifications

    Nothing in Physics limits the amount of energy that can be bound into a laser beam. Funnily enough a death star type laser is actually possible :) cheers Dave

    Protective viewing window, film, or enclosure

    Therein lays half the problem, I treat my 7.5kW CO2 with less respect than I do a 50 watt RF Galvo. The physical presence of a machine near the size of a small house tends to demand respect just because *it exists*, tiny little Galvo's that look like toys in comparison don't have the same kind...
