Buy an Axon, Axon II, or Axon Mote and build a great robot, while helping to support SoR.

If you do, please let me know where because I could have some major fun with a 1W laser. (*poof* and Andrew goes on the homeland security watch list for that one statement)
check out this one toohttp://www.dragonlasers.com/catalog/Aurora-GW-price0-p-1-c-274.html
You know had you found that 1000mW laser a week ago it would have been great. My girlfriend had lasik eye surgery last Friday, she could have just given me the $3K for the laser and I could have done the surgery, saving her $2K. Either way, she would have never needed glasses again. Muahahahaha
Those lasermate high power diodes look pretty promising, but you would probably need a focusing lens of some sort (basing that statement off the beam divergence spec). I wonder if they will sell them to the general public... I'll get a friend to call
very nice design BANE , very organizedyou used CNC right?
No, not at all actually, I used a jig saw w/ super fine blade and some mad machining skillzzzz But hey, it took alittle more time but saved alot of $$$$I'm going to make a totoral on it someday when i get it finishedBane
If I am not mistaken the last page of the instructables article you are referring to had a comment where someone posted a schematic for a proper powersupply for the laser. $4.50 for the laser housing (the 5mW brass housing referred to in the article), $20 for a DVD burner, and about $10-15 for parts for the power supply and you can "legally" build yourself out a higher watt laser.

I'm making this robot for my college portfolio and i just thought that using a laser would be a cool yet difficult project to make. I mean how many kids make robot's that use a laser to make something? The melting of two pieces on plastic has no purpose other than being able to do it. And don't get me wrong on this but if someone gots a better way to make something cool, i'm all ears .Bane
Make sure your plastic wheels aren't made out of polyvinyl chloride. That stuff is Bad bad bad for you (if burnt). We cant put that stuff in our lasers because, not only can it be lethal, it's also caustic.

OK, the old soldering iron looks like my best option. I want my robot to be all battery operated though, if i used a 9.6 vdc 1.3ah drill battery to just power the iron, do you think it will work? I have never tried running a AC appliance with DC .Bane
Hello, I am working on a robot that can welding two small pieces of plastic with a laser.
me now, and I am wondering why you want to melt the wheels together with a laser instead of some other method like a hot air iron or even chemical welding? Given the difficulty of finding a high enough power laser and the price associated, not to mention the actual danger to your poor eyeballs; it would seem there would be better choices out there.
