Neat! Looks like the focusing lens out of an old, dead CDROM drive I've got sitting around will work for this too! Now I just need some plexi glass and maybe a couple of bolts.

I was ready to get all indignant and decry the $10 price tag as not including the laser pointer that you have to destroy to get at the lens, but I was pleasantly surprised to learn that $10 gets you all the materials (besides the smartphone).
Very cool. Any idea when the followup $20 scanning-electron microscope attachment is forthcoming?

You could probably get a crude STM going for $20 (if you have the right parts in your junk bin). I recall a colleague of a friend of mine (physics prof) building a crude one in the early 90's with discarded stuff from a university -- he spent a lot more money and time over the following years refining his build with vacuum and cryogenics and a much more precise positioning system.
to bring it back to TFA, you could interface it with your phone through the earphone jack

Oh man, I turfed all my old CD-ROM drives and burners years ago. Not sure I want to sacrifice a DVD drive...
