Transfer to your veroboard and solder it up. Again, goggles/glasses and a fan are really good to have. I build a fan out of a PC fan hooked up to a switch and a 9v power supply. It's a 12v fan, but it goes fast enough to blow all the fumes away, and I hardly smell anything while it's on. There are all kinds of nasty things that happen if you breath in enough of these fumes, or so I'm told. Either way, they smell bad, so It's probably not a good idea to go breaking them in.

I left the switch and LED disconnected. Why? So I could mod them into a nifty case, of course (and because the switch doesn't have pins).
