This looks like a neat little project. We've had our share of fun with microscopes here at Digital Diner. This particular one looks pretty sweet because you can make it yourself fairly cheaply and it uses the fancy camera parts of your smartphone to give you some advanced functions like time lapse photography. The tricky bit is finding a cheap laser pointer whose lens you can steal. Everything else looks very straight forward. You end up with great, high resolution images showing the wonders of the tiny worlds all around us. Seems worth a try to me.
