This is an interesting project for gathering pollen samples for analysis. It’s basically a fan controlled by a PIC16F690. The fan draws air over a piece of sticky tape for a specific amount of time in hopes of catching some airborne particles. Apparently it works quiet well. Be sure to check out the all the pictures of the pollen, spores, and “weird stuff” that was collected.
The idea is simple: a timer-controlled fan would produce constant airflow over a sticky tape and hopefully will make some of the airborne particles stick; attach the tape on a slide, pop it under the microscope and you are in business.

Excellent little project. And would you believe right on the desk I do all my PIC programming and electronics projects I happen to have a microscope. I usually look at things in pond water or sea water but I might give this a try having enough bits in the junk box to make one. I didn’t know about hydrating the pollen to see the true shape either. Luckily I also happen to have some isopropyl and glycerin here too. It’s good to be a well prepared geek!
BTW, that box loos lie it might have been some kind of Satellite dish setup tool? A fancy alignment/signal strength meter?
