If you want to push the power of the laser I think one would need to do something wacky , like sending pure oxygen in to get the heat high enough to start burning metal.<br><br>There is a group that has made a modification to the air assist system. They channel the air and the laser through a gap to try and get more cutting power.<br>

It does open the road to potential hacking in the future, definitely if you start mixing gases.<br>

The laser unfortunately can't cut through metal. The best one can do
is to coat the board in black spraypaint, remove it with the laser and
use it as a resist.<br><br><a href="http://blog.makezine.com/archive/2007/01/how-to-use-a-laser-to-etc.html" target="_blank">http://blog.makezine.com/archive/2007/01/how-to-use-a-laser-to-etc.html</a><div><div></div><div>

We should try some copper clad board to see if we can cut a PCB with the laser... I've seen some people with fantastic success, and that laser is so fine that we could get some really accurate PCB traces with it.<div>

Hehe. Good idea. <br><br>It isn't that small yet. Using three credit cards I can build two trebuchettes. It is based on these guys design, which uses no glue or tape to hold the whole thing together:<br><br><a href="http://www.siegetoys.com/design.html" target="_blank">http://www.siegetoys.com/design.html</a><div>
